Safety Information
engine saFetY
danger
„ The engine fuel exhaust gases contain poisonous carbon
monoxide. This gas is colorless and odorless, and can
cause death if inhaled.
„ The engine of this equipment
requires an adequate free
flow of cooling air. never
operate this equipment in
any enclosed or narrow area
where free flow of the air is
restricted. If the air flow is
restricted it will cause injury to people and property and
serious damage to the equipment or engine.
Warning
„ do not place hands or fingers inside engine
compartment when engine is running.
„ never operate the engine with heat shields or
guards removed.
„ keep fingers, hands hair and clothing away
from all moving parts to prevent injury.
„ do not remove the radiator cap while the
engine is hot. High pressure boiling water
will gush out of the radiator and severely
scald any persons in the general area of
the generator.
„ do not remove the coolant drain plug while the engine
is hot. Hot coolant will gush out of the coolant tank and
severely scald any persons in the general area of the
generator.
„ do not remove the engine oil drain plug while the
engine is hot. Hot oil will gush out of the oil tank and
severely scald any persons in the general area of the
generator.
Caution
„ never touch the hot exhaust manifold,
muffler or cylinder. Allow these parts to cool
before servicing equipment.
NOTICE
„ never run engine without an air filter or with a dirty air
filter. Severe engine damage may occur. Service air filter
frequently to prevent engine malfunction.
„ never tamper with the factory settings
of the engine or engine governor. Damage
to the engine or equipment can result
if operating in speed ranges above the
maximum allowable.
„ Wet stacking is a common problem with diesel engines
which are operated for extended periods with light or
no load applied. When a diesel engine operates without
sufficient load (less than 40% of the rated output), it will
not operate at its optimum temperature. This will allow
unburned fuel to accumulate in the exhaust system,
which can foul the fuel injectors, engine valves and
exhaust system, including turbochargers, and reduce
the operating performance.
In order for a diesel engine to operate at peak efficiency,
it must be able to provide fuel and air in the proper ratio
and at a high enough engine temperature for the engine
to completely burn all of the fuel.
Wet stacking does not usually cause any permanent
damage and can be alleviated if additional load is
applied to relieve the condition. It can reduce the system
performance and increase maintenance. Applying an
increasing load over a period of time until the excess
fuel is burned off and the system capacity is reached
usually can repair the condition. This can take several
hours to burn off the accumulated unburned fuel.
„ State Health Safety Codes and Public Resources
Codes specify that in certain locations, spark arresters
must be used on internal combustion engines that use
hydrocarbon fuels. A spark arrester is a device designed
to prevent accidental discharge of sparks or flames
from the engine exhaust. Spark arresters are qualified
and rated by the United States Forest Service for this
purpose. In order to comply with local laws regarding
spark arresters, consult the engine distributor or the
local Health and Safety Administrator.

Installation
Outdoor Installation
Generator Grounding
Install the generator in a area that is free of debris,
bystanders, and overhead obstructions. Make sure the
generator is on secure level ground so that it cannot slide
or shift around. Also install the generator in a manner so
that the exhaust will not be discharged in the direction of
nearby homes.
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground (Figure 2).
The installation site must be relatively free from moisture
and dust. All electrical equipment should be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in short circuits and
grounding.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
CAUTION
Pay close attention to ventilation when operating the
generator inside tunnels and caves. The engine exhaust
contains noxious elements. Engine exhaust must be
routed to a ventilated area.
Indoor Installation
Exhaust gases from diesel engines are extremely
poisonous. Whenever an engine is installed indoors the
exhaust fumes must be vented to the outside. The engine
should be installed at least two feet from any outside wall.
Using an exhaust pipe which is too long or too small can
cause excessive back pressure which will cause the engine
to heat excessively and possibly burn the valves.
Article 250 (Grounding) of the National Electrical Code
(NEC) provides guide lines for proper grounding and
specifies that the cable ground shall be connected to the
grounding system of the building as close to the point of
cable entry as practical.
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
1. Use one of the following wire types to connect the
generator to earth ground.
a. Copper - 8 AWG (5.3 mm2) or larger.
b. Aluminum - 6 AWG (8.4 mm2) or larger.
2. When grounding the generator (Figure 2) connect the
ground cable between the lock washer and the nut on
the generator and tighten the nut fully. Connect the
other end of the ground cable to earth ground.
3. NEC article 250-52(c) specifies that the earth ground rod
should be buried a minimum of 8 ft. into the ground.
NOTICE
When connecting the generator to any buildings
electrical system ALWAYS consult with a licensed
electrician.
Mounting
The generator must be mounted on a solid foundation (such
as concrete) and set firmly on the foundation to isolate
vibration of the generator when it is running. The generator
must set at least 6 inches above the floor or grade level (in
accordance to NFPA 110, Chapter 5-4.1). DO NOT remove
the metal skids on the bottom of the generator. They are
to resist damage to the bottom of the generator and to
maintain alignment.

General Information
Generator
Open Delta Excitation System
The MQ Power Model DCA20SPXU2 generator (Figure 3)
is a high quality portable (requires a trailer for transport)
power source for telecom sites, lighting facilities, power
tools, submersible pumps and other industrial and
construction machinery.
This generator is equipped with the state of the art “OpenDelta” excitation system. The open delta system consist
of an electrically independent winding wound among
stationary windings of the AC output section.
There are four connections of the open delta A, B, C and
D. During steady state loads, the power from the voltage
regulator is supplied from the parallel connections of A to
B, A to D, and C to D. These three phases of the voltage
input to the voltage regulator are then rectified and are the
excitation current for the exciter section.
When a heavy load, such as a motor starting or a short
circuit occurs, the automatic voltage regulator (AVR)
switches the configuration of the open delta to the series
connection of B to C. This has the effect of adding the
voltages of each phase to provide higher excitation to the
exciter section and thus better voltage response during the
application of heavy loads.
The connections of the AVR to the AC output windings are
for sensing only. No power is required from these windings.
The open-delta design provides virtually unlimited excitation
current, offering maximum motor starting capabilities. The
excitation does not have a “fixed ceiling” and responds
according the demands of the required load.

The definitions below describe the controls and functions
of the Engine Control Panel (Figure 6).
1. Oil Pressure Gauge — During normal operation this
gauge should read between 35 to 65 psi. (241~448 kPa).
When starting the generator the oil pressure may read a
little higher, but after the engine warms up the oil pressure
should return to the correct pressure range.
2. Water Temperature Gauge — During normal operation this
gauge be should read between 180°~221°F (82°~105°C)
3. Charging Ammeter Gauge — Indicates the current
being supplied by the engine’s alternator which provides
current for generator’s control circuits and battery
charging system.
4. Fuel Gauge — Indicates amount of diesel fuel available.
5. Tachometer — Indicates engine speed in RPM’s for 60
Hz operation. This meter should indicate 1800 RPM’s
when the rated load is applied. In addition a built in hour
meter will record the number of operational hours that
the generator has been in use.
6. Panel Light — Normally used in dark areas or at night
time. When activated, panel lights will illuminate. When
the generator is not in use be sure to turn the panel light
switch to the OFF position.
7. Panel Light Switch — When activated will turn on control
panel light.
8. Fuel Filter Water Level Alarm Lamp — This lamp will
illuminate when water in the fuel filter has reached an
abnormal level.
9. Auto START/STOP Engine
Controller (ECU) — This controller
has a vertical row of status LED's
(inset), that when lit, indicate
that an engine malfunction (fault)
has been detected. When a fault
has been detected the engine
controller will evaluate the fault
and all major faults will shutdown
the generator. During cranking
cycle, the ECU will attempt to crank the engine for 10
seconds before disengaging.
Also the engine controller will shut down the engine in
the event of low oil pressure, high coolant temperature,
low coolant level, and loss of magnetic pickup. These
conditions can be observed by monitoring the LED
status indicators on the front of the controller module.
A. MPEC Control Switch — This switch controls the
running of the unit. If this switch is set to the OFF/
RESET position, the unit will not run. When this switch
is set to the manual position, the generator will start
immediately.
If the generator is to be connected to a building’s
AC power source via an automatic transfer switch
(isolation), place the switch in the AUTO position. In this
position, should an outage occur, the automatic transfer
switch (ATS) will start the generator automatically
via the generator’s auto-start contacts connected to
the ATS’s start contacts. Please refer to your ATS
installation manual for further instructions for the
correct installation of the auto-start contacts of the
generator to the ATS.
B. Low Oil Pressure — Indicates the engine pressure
has fallen below 15 psi (103 kPa). The oil pressure is
detected using variable resistive values from the oil
pressure sending unit. This is considered a major fault.
C. High Coolant Temperature — Indicates the engine
temperature has exceeded 230°F (110°C). The engine
temperature is detected using variable resistive values
from the temperature sending unit. This is considered
a major fault.
D. Overcrank Shutdown — Indicates the unit has
attempted to start a pre- programmed number of
times, and has failed to start. The number of cycles and
duration are programmable. It is pre-set at 3 cycles with
a 10 second duration. This is considered a major fault.
E. Overspeed Shutdown — Indicates the engine is
running at an unsafe speed. This is considered a
major fault.
F. Engine Running — Indicates that engine is running
at a safe operating speed.
If the engine does not engage (start) by the third
attempt, the engine will be shutdown by the engine
controller’s Over Crank Protection mode. If the engine
engages at a speed (RPM's) that is not safe, the
controller will shutdown the engine by initializing the
Over Speed Protection mode.

Load Application/Generator output
Single Phase Load
Always be sure to check the nameplate on the generator
and equipment to insure the wattage, amperage, frequency,
and voltage requirements are satisfactorily supplied by the
generator for operating the equipment.
Generally, the wattage listed on the nameplate of the
equipment is its rated output. Equipment may require
130—150% more wattage than the rating on the nameplate,
as the wattage is influenced by the efficiency, power factor
and starting system of the equipment.
NOTICE
If wattage is not given on the equipment’s name plate,
approximate wattage may be determined by multiplying
nameplate voltage by the nameplate amperage.
WATTS = VOLTAGE x AMPERAGE
The power factor of this generator is 0.8. See Table 6 below
when connecting loads.

Motors and motor-driven equipment draw much greater
current for starting than during operation.
An inadequate size connecting cable which cannot carry the
required load can cause a voltage drop which can burn out
the appliance or tool and overheat the cable. See Table 7
„„When connecting a resistance load such as an
incandescent lamp or electric heater, a capacity of up
to the generating set’s rated output (kW) can be used.
„„When connecting a fluorescent or mercury lamp, a
capacity of up to the generating set’s rated output (kW)
multiplied by 0.6 can be used.
„„When connecting an electric drill or other power tools,
pay close attention to the required starting current
capacity.
When connecting ordinary power tools, a capacity of up to
the generating set’s rated output (kW) multiplied by 0.8 can
be used.
DANGER
Before connecting this generator to any building’s
electrical system, a licensed electrician must install
an isolation (transfer) switch. Serious damage to
the building’s electrical system may occur without this
transfer switch.

General Inspection
Prior to each use, the generator should be cleaned and
inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts or other fasteners. Also check for
fuel, oil, and coolant leaks. Use Table 12 as a general
maintenance guideline Engine Side (Refer to the Engine
Instruction Manual)
Air Cleaner
Every 250 hours: Remove air cleaner element (Figure 40)
and clean the heavy duty paper element with light spray of
compressed air. Replace the air cleaner as needed.
Air Cleaner with Dust Indicator
This indicator (Figure 40) is attached to the air cleaner.
When the air cleaner element is clogged, air intake
restriction becomes greater and the dust indicator signal
shows RED meaning the element needs changing or
service. After changing the air element, press the dust
indicator button to reset the indicator.
Figure 40. Air Cleaner/Indicator
NOTICE
The air filter should not be changed until the indicator
reads “RED”. Dispose of old air filter. It may not be
cleaned or reused.
DCA20spxu2 servpro® • operation and parts manual — rev. #0 (09/23/13) — page 35
Maintenance
If the engine is operating in very dusty or dry grass
conditions, a clogged air cleaner will result. This can lead to
a loss of power, excessive carbon buildup in the combustion
chamber and high fuel consumption. Change air cleaner
more frequently if these conditions exists.
Fuel Tank Inspection
In addition to cleaning the fuel tank, the following
components should be inspected for wear:
Fuel Addition
„„Rubber Suspension — look for signs of wear or
deformity due to contact with oil. Replace the rubber
suspension if necessary.
Add diesel fuel (the grade may vary according to season
and locations).
„„Fuel Hoses — inspect nylon and rubber hoses for signs
of wear, deterioration and hardening.
Removing Water from the Fuel Tank
„„Fuel Tank Lining — inspect the fuel tank lining for signs
of excessive amounts of oil or other foreign matter.
After prolonged use, water and other impurities accumulate
in the bottom of the tank. Occasionally inspect the fuel
tank for water contamination and drain the contents if
required.
During cold weather, the more empty volume inside the
tank, the easier it is for water to condense. This can be
reduced by keeping the tank full with diesel fuel.
Cleaning Inside the Fuel Tank
If necessary, drain the fuel inside the fuel tank completely.
Using a spray washer (Figure 41) wash out any deposits
or debris that have accumulated inside the fuel tank.
Replacing Fuel Filter
„„Replace the fuel filter cartridge with new one every 500
hours or so.
„„Loosen the drain plug at the lower top of the fuel filter.
Drain the fuel in the fuel body together with the mixed
water. DO NOT spill the fuel during disassembly.
„„Vent any air
Air Removal
If air enters the fuel injection system of a diesel engine,
starting becomes impossible. After running out of fuel,
or after disassembling the fuel system, bleed the system
according to the following procedure. See the ISUZU
Engine Manual for details.
To restart after running out of fuel, turn the switch to the ON
position for 15-30 seconds. Try again, if needed.
Figure 41. Fuel Tank Cleaning
page 36 — DCA20spxu2 servpro® • operation and parts manual — rev. #0 (09/23/13)
Maintenance
Check Oil Level
Radiator Cleaning
Check the crankcase oil level prior to each use, or when the
fuel tank is filled. Insufficient oil may cause severe damage
to the engine. Make sure the generator is level. The oil level
must be between the two notches on the dipstick as shown
in Figure 17 .
The radiator (Figure 42) should be sprayed (cleaned) with
a high pressure washer when excessive amounts of dirt
and debris have accumulated on the cooling fins or tube.
When using a high pressure washer, stand at least 5 feet
(1.5 meters) away from the radiator to prevent damage to
the fins and tube.
Replacing Oil Filter
„„Remove the old oil filter.
„„Apply a film of oil to the gasket on the new oil filter.
„„Install the new oil filter.
„„After the oil cartridge has been replaced, the engine oil
will drop slightly. Run the engine for a while and check for
leaks before adding more oil if needed. Clean excessive
oil from engine.
Flushing Out Radiator and Replacing
Coolant
„„Open both cocks located at the crankcase side and at
the lower part of the radiator and drain coolant. Open
the radiator cap while draining. Remove the overflow
tank and drain.
„„Check hoses for softening and kinks. Check clamps for
signs of leakage.
Figure 42. Radiator Cleaning
Generator Storage
For long term storage of the generator the following is
recommended:
„„Tighten both cocks and replace the overflow tank.
„„Drain the fuel tank completely. Treat with a fuel stabilizer
if necessary.
„„Replace with coolant as recommended by the engine
manufacturer.
„„Completely drain the oil from the crankcase and refill if
necessary with fresh oil.
„„Close radiator cap tightly.
„„Clean the entire generator, internal and external.
„„Flush the radiator by running clean tap water through
radiator until signs of rust and dirt are removed. DO
NOT clean radiator core with any objects, such as a
screwdriver.
„„Cover the generating set and store in a clean, dry place.
WARNING
Allow engine to cool when flushing out
radiator. Flushing the radiator while hot
could cause serious burns from water or
steam.
„„Disconnect the battery.
„„Make sure engine coolant is at proper level.
„„If generator is mounted on a trailer, jack trailer up and
place on blocks so tires do not touch the ground or block
and completely remove the tires.

Jacket Water Heater and Internal Battery
Charger 120 VAC Input Receptacles
This generator can be optionally equipped with a single
120 VAC, 15 amp input receptacle (Figure 43) located on
the output terminal panel.
The purpose of this receptacle is to provide power via
commercial power to the jacket water heater and internal
battery charger (Figure 44).
The receptacle will ONLY function when commercial power
has been supplied to it. To apply commercial power to the
receptacle, a power cord of adequate size will be required
(See Table 7).
When using the generator in hot climates there is no
reason to apply power to jacket water heater. However, if
the generator will be used in cold climates it is always a
good idea to apply power to the jacket water heater at all
times. To apply power to the jacket water heater simply
apply power to the jacket water heater receptacle via
commercial power using an power cord of adequate size.
If the generator will be used daily, the battery should
normally not require charging. If the generator will be idle
(not used) for long periods of time, apply power to the
battery charger receptacle via commercial power using a
power cord of adequate size.
NOTICE
To ensure adequate starting capability, always have
power applied to the generator's internal battery
charger.

Wheel Bearings
Wheel bearings (Figure 46) must be inspected and
lubricated once a year or 12,000 miles to insure safe
operation of your trailer.
If trailer wheel bearings are immersed in water, they must
be replaced.
DANGER
If trailer wheels are under water for a long period of
time, wheel bearings may fail. If this is the case, service
wheel bearings immediately.
The possibility exists of the wheels falling off causing
equipment damage and severe bodily harm even death!
„„Lubricate the bearings with a high quality EP-2
automotive wheel bearing grease.
Wheel Hub Adjustment
Every time the wheel hub is removed and the bearings are
reassembled, follow the steps below to check the wheel
bearings for free running and adjust.
„„Turn the hub slowly, by hand, while tightening the spindle
nut until you can no longer turn the hub by hand.
„„Loosen the spindle nut just until you are able to turn it
(the spindle nut) by hand. Do not turn the hub while the
spindle nut is loose.
„„Install a new cotter pin through the spindle nut and axle.
„„Check the adjustments. Both the hub and the spindle nut
should be able to move freely (the spindle nut motion
will be limited by the cotter pin).

Trailer guidelines
The following guidelines are intended to assist the operator
in the operation and handling of a trailer.
„ Shift your automatic transmission into a lower gear for
city driving.
Safety precautions should be followed at all times when
operating a trailer. Failure to read, understand and follow
the safety guidelines could result in injury to yourself and
others. Loss of control of the trailer or tow vehicle can result
in death or serious injury.
„ alWaYs use lower gears for climbing and descending
grades.
Common Causes For loss oF trailer
„ Driving too fast for the conditions (maximum speed when
towing a trailer is 55 mph).
„ Overloading the trailer or loading the trailer unevenly.
„ Trailer improperly coupled to the hitch.
„ No braking on trailer.
„ Not maintaining proper tire pressure.
„ Not keeping lug nuts tight.
„ Not properly maintaining the trailer structure.
„ Ensure machine is towed level to tow vehicle.
trailer toWing guidelines
„ Recheck the load tiedowns to make sure the load will
not shift during towing.
„ Before towing, check coupling, safety chain, safety
brake, tires, wheels and lights.
„ Check the lug nuts or bolts for tightness.
„ Check coupler tightness after towing 50 miles.
„ Use your mirrors to verify that you have room to change
lanes or pull into traffic.
„ Use your turn signals well in advance. Allow plenty of
stopping space for your trailer and tow vehicle.
„ Allow plenty of stopping space for your trailer and tow
vehicle.
„ do not drive so fast that the trailer begins to sway
due to speed.
„ Allow plenty of room for passing. A rule of thumb is that
the passing distance with a trailer is 4 times the passing
distance without the trailer.
„ do not ride the brakes while descending grades, they
may get so hot that they stop working. Then you will
potentially have a runaway tow vehicle and trailer.
„ To conserve fuel, don’t use full throttle to climb a hill.
Instead, build speed on the approach.
„ Slow down for bumps in the road. Take your foot off the
brake when crossing the bump.
„ do not brake while in a curve unless absolutely
necessary. Instead, slow down before you enter the
curve and power through the curve. This way, the towing
vehicle remains in charge.
„ do not apply the brakes to correct extreme trailer
swaying. Continued pulling of the trailer, and even slight
acceleration, will provide a stabilizing force.
„ Anticipate the trailer “swaying.” Swaying is the trailer
reaction to the air pressure wave caused by passing
trucks and buses. Continued pulling of the trailer provides
a stabilizing force to correct swaying. DO NOT apply the
brakes to correct trailer swaying.
„ Use lower gear when driving down steep or long grades.
Use the engine and transmission as a brake. Do not
ride the brakes, as they can overheat and become
ineffective.
„ Be aware of your trailer height, especially when
approaching roofed areas and around trees.
„ Make regular stops, about once each hour. Confirm
that:
•Coupler is secure to the hitch and is locked.
•Electrical connectors are secure.
•There is appropriate slack in the safety chains.
•There is appropriate slack in the breakaway switch
pullpin cable.
•Tires are not visibly low on pressure.
DCA20spxu2 servpro® • operation and parts manual — rev. #0 (09/23/13) — page 41
Trailer guidelines
driving Conditions
When towing a trailer, you will have decreased acceleration,
increased stopping distance, and increased turning radius
(which means you must make wider turns to keep from
hitting curbs, vehicles, and anything else that is on the
inside corner). In addition, you will need a longer distance
to pass, due to slower acceleration and increased length.
„ Be alert for slippery conditions. You are more likely to be
affected by slippery road surfaces when driving a tow
vehicle with a trailer, than driving a tow vehicle without
a trailer.
„ Check rearview mirrors frequently to observe the trailer
and traffic.
„ never drive faster than what is safe.
Warning
Driving too fast for severe road conditions can result in
loss of control and cause death or serious injury.
Decrease your speed as road, weather, and lighting
conditions deteriorate.
Always check for local trailer tow speed limits in your
area.
Warning
Do not transport people on the trailer. The transport of
people puts their lives at risk and may be illegal.
Coupling to tHe toW veHiCle
Follow all of the safety precautions and instructions in
this manual to ensure safety of persons, equipment, and
satisfactory life of the trailer. Always use an adequate tow
vehicle and hitch. If the vehicle or hitch is not properly
selected and matched to the Gross Vehicle Weight Rating
(GVWR) of your trailer, you can cause an accident that
could lead to death or serious injury.
If you already have a tow vehicle, know your vehicle tow
rating and make certain the trailer’s rated capacity is less
than or equal to the tow vehicle’s rated towing capacity. If
you already have (or plan to buy) a trailer, make certain
that the tow rating of the tow vehicle is equal to or greater
than that of the trailer.
The trailer VIN tag contains the critical safetyinformation
for the use of your trailer. Again, be sure your hitch and tow
vehicle are rated for the Gross Vehicle Weight Rating of
your trailer.
Warning
Proper selection and condition of the coupler and hitch
are essential to safely towing your trailer. A loss of
coupling may result in death or serious injury.
• Be sure the hitch load rating is equal to or greater
than the load rating of the coupler.
• Be sure the hitch size matches the coupler size.
• Observe the hitch for wear, corrosion and cracks
before coupling. Replace worn, corroded or cracked
hitch components before coupling the trailer to the
tow vehicle.
• Be sure the hitch components are tight before
coupling the trailer to the tow vehicle.
Warning
An improperly coupled trailer can result in death or
serious injury.
do not move the trailer until:
• The coupler is secured and locked to hitch.
• The safety chains are secured to the tow vehicle.
• The trailer jack(s) are fully retracted.
do not tow the trailer on the road until:
• Tires and wheels are checked.
• The trailer brakes are checked.
• The breakaway switch is connected to the tow vehicle.
• The load is secured to the trailer.
• The trailer lights are connected and checked.
Warning
Use of a hitch with a load rating less than the load rating
of the trailer can result in loss of control and may lead
to death or serious injury.
Use of a tow vehicle with a towing capacity less than
the load rating of the trailer can result in loss of control,
and may lead to death or serious injury.
Be sure your hitch and tow vehicle are rated for the
Gross Vehicle Weight Rating of your trailer.
page 42 — DCA20spxu2 servpro® • operation and parts manual — rev. #0 (09/23/13)
Trailer guidelines
inoperaBle Brakes, ligHts or mirrors
Be sure that the brakes and all of the lights on your trailer
are functioning properly before towing your trailer. Check
the trailer taillights by turning on your tow vehicle headlights.
Check the trailer brake lights by having someone step on
the tow vehicle brake pedal while you look at trailer lights.
Do the same thing to check the turn signal lights. See Trailer
Wiring Diagram section in this manual.
Standard mirrors usually do not provide adequate visibility
for viewing traffic to the sides and rear of a towed trailer.
You must provide mirrors that allow you to safely observe
approaching traffic.
Warning
Improper electrical connection between the tow vehicle
and the trailer will result in inoperable lights and can
lead to collision.
Before each tow, check that the tail lights, brake lights
and turn signals work.
trailer toWing tips
Driving a vehicle with a trailer in tow is vastly different
from driving the same vehicle without a trailer in tow.
Acceleration, maneuverability and braking are all diminished
with a trailer in tow.
It takes longer to get up to speed, you need more room to
turn and pass, and more distance to stop when towing a
trailer. You will need to spend time adjusting to the different
feel and maneuverability of the tow vehicle with a loaded
trailer.
Because of the significant differences in all aspects of
maneuverability when towing a trailer, the hazards and risks
of injury are also much greater than when driving without
a trailer. You are responsible for keeping your vehicle and
trailer in control, and for all the damage that is caused if
you lose control of your vehicle and trailer.
As you did when learning to drive an automobile, find
an open area with little or no traffic for your first practice
trailering. Of course, before you start towing the trailer, you
must follow all of the instructions for inspection, testing,
loading and coupling. Also, before you start towing, adjust
the mirrors so you can see the trailer as well as the area
to the rear of it.
Drive slowly at first, 5 mph or so, and turn the wheel to
get the feel of how the tow vehicle and trailer combination
responds. Next, make some right and left hand turns.
Watch in your side mirrors to see how the trailer follows
the tow vehicle. Turning with a trailer attached requires
more room.
Stop the rig a few times from speeds no greater than
10 mph. If your trailer is equipped with brakes, try using
different combinations of trailer brake and tow vehicle brake.
Note the effect that the trailer brakes have when they are
the only brakes used. When properly adjusted, the trailer
brakes will come on just before the tow vehicle brakes.
It will take practice to learn how to back up a tow vehicle
with a trailer attached. Take it slow. Before backing up, get
out of the tow vehicle and look behind the trailer to make
sure that there are no obstacles.
Some drivers place their hands at the bottom of the steering
wheel, and while the tow vehicle is in reverse, “think” of the
hands as being on the top of the wheel. When the hands
move to the right (counterclockwise, as you would do to
turn the tow vehicle to the left when moving forward), the
rear of the trailer moves to the right. Conversely, rotating
the steering wheel clockwise with your hands at the bottom
of the wheel will move the rear of the trailer to the left while
backing up.
If you are towing a bumper hitch rig, be careful not to allow
the trailer to turn too much because it will hit the rear of the
tow vehicle. To straighten the rig, either pull forward or turn
the steering wheel in the opposite direction.
trailer vin tag
Figure A below is a sample of the Vehicle Identification
Number (VIN) Tag which is typically located on the left front
of the trailer. See Figure B for location.

Trailer guidelines
To determine the “empty” or “net” weight of your trailer,
weigh it on an axle scale. To find the weight of the trailer
using an axle scale, you must know the axle weights of
your tow vehicle without the trailer coupled. Some of the
trailer weight will be transferred from the trailer to the tow
vehicle axles, and an axle scale weighs all axles, including
the tow vehicle axles.

The trailer VIN Tag contains the following critical safety
information for the use of your trailer.
toW veHiCle
The towing hitch attached to your tow vehicle must have a
capacity equal to or greater than the load rating of the trailer
you intend to tow. The hitch capacity must also be matched
to the tow vehicle capacity. Your vehicle dealer can provide
and install the proper hitch on your tow vehicle.
suspension sYstem
gaWR: The maximum gross weight that an axle cansupport.
It is the lowest of axle, wheel, or tire rating.
Sway bars, shock absorbers, heavy duty springs, heavy
duty tires and other suspension components may be
required to sufficiently tow the trailer and pump.
Usually, the tire or wheel rating is lower than the axle rating,
and determines GAWR.
side vieW mirrors
gVWR: The maximum allowable gross weight of the trailer
and its contents. The gross weight of the trailer includes
the weight of the trailer and all of the items within it. GVWR
is sometimes referred to as GTWR (Gross Trailer Weight
Rating), or MGTW (Maximum Gross Trailer Weight). GVWR,
GTWR and MGTW are all the same rating.
The sum total of the GAWR for all trailer axles may be less
than the GVWR for the trailer, because some of the trailer
load is to be carried by the tow vehicle, rather than by the
trailer axle(s). The total weight of the cargo and trailer must
not exceed the GVWR, and the load on an axle must not
exceed its GAWR.
psiC: The tire pressure (psi) measured when cold.
vin: The Vehicle Identification Number.
emptY WeigHt: Some information that comes with the
trailer (such as the Manufacturer’s Statement of Origin)
is not a reliable source for “empty” or “net” weight. The
shipping documents list average or standard weights and
your trailer may be equipped with options.
The size of the trailer that is being towed and your state
law regulations determine the size of the mirrors. However,
some states prohibit extended mirrors on a tow vehicle,
except while a trailer is actually being towed. In this
situation, detachable extended mirrors are necessary.
Check with your dealer or the appropriate state agency
for mirror requirements.
HeavY dutY FlasHer
A Heavy Duty Flasher is an electrical component that may
be required when your trailer turn signal lights are attached
to the tow vehicle flasher circuit.
eleCtriCal ConneCtor
An Electrical Connector connects the lights on the trailer
to the lights on the towing vehicle.
emergenCY Flares and triangle reFleCtors
It is wise to carry these warning devices even if you are
not towing a trailer. It is particularly important to have these
when towing a trailer because the hazard flashers of your
towing vehicle will not operate for as long a period of time
when the battery is running both the trailer lights and tow
vehicle lights.

saFetY CHains
If the coupler connection comes loose, the safety chains
can keep the trailer attached to the tow vehicle. With
properly rigged safety chains, it is possible to keep the
tongue of the trailer from digging into the road pavement,
even if the coupler-to-hitch connection comes apart.
JaCkstand
A device on the trailer that is used to raise and lower the
coupler. The jack is sometimes called the “landing gear” or
the “tongue jack”.
Coupler tYpes
Two types of coupler used with the trailer are discussed
below.
„ Ball Hitch Coupler
„ Pintel Eye Coupler
Ball HitCH Coupler
A ball hitch coupler (Figure C) connects to a ball that is
located on or under the rear bumper of tow vehicle. This
system of coupling a trailer to a tow vehicle is sometimes
referred to as “bumper pull.”
A ball hitch trailer may be fitted with a tongue jack that can
raise and lower the coupler. The tongue jack is mounted to
the A-frame (front or tongue) part of the trailer. By rotating
the jack handle clockwise, the jack will extend and raise
the tongue of the trailer.
Check the locking device that secures the coupler to the
ball for proper operation.
If you see or feel evidence of wear, such as flat spots,
deformations, pitting or corrosion, on the ball or coupler,
immediately have your dealer inspect them to determine
the proper action to prevent possible failure of the ball and
coupler system. All bent or broken coupler parts must be
replaced before towing the trailer.
The coupler handle lever must be able to rotate freely and
automatically snap into the latched position. Oil the pivot
points, sliding surfaces, and spring ends with SAE 30W
motor oil. keep the ball socket and latch mechanism clean.
Dirt or contamination can prevent proper operation of the
latching mechanism.
The load rating of the coupler and the necessary ball size
are listed on the trailer tongue. You must provide a hitch and
ball for your tow vehicle where the load rating of the hitch
and ball is equal to or greater than that of your trailer.
Also, the ball size must be the same as the coupler size. If
the hitch ball is too small, too large, is underrated, is loose
or is worn, the trailer can come loose from the tow vehicle
and may cause death or serious injury.
THE TOW VEHICLE, HITCH AND BALL MUST HAVE A
RATED TOWING CAPACITY EQUAL TO OR GREATER
THAN THE TRAILER gross vehicle Weight rating
(gvWr). IT IS ESSENTIAL THAT THE HITCH BALL BE
OF THE SAME SIZE AS THE COUPLER.
The ball size and load rating (capacity) are marked on the
ball. Hitch capacity is marked on the hitch.
Warning
Coupler-to-hitch mismatch can result in uncoupling,
leading to death or serious injury.
Be sure the LOAD RATING of the hitch ball is equal or
greater than the load rating of the coupler.
Be sure the SIZE of the hitch ball matches the size of
the ball coupler.

inside of the coupler for worn spots and pits.
„ Be sure the coupler is secured tightly to the tongue of the
trailer. All coupler fasteners must be visibly solid against
the trailer frame.
„ The bottom surface of the coupler must be above the top
of the hitch ball. Use the tongue jackstand to support
the trailer tongue. Wood or concrete blocks may also
be used.
Coupling the trailer to the tow vehicle (Ball Coupler)
„ Lubricate the hitch ball and the inside of the coupler with
a thin layer of automotive bearing grease.
„ Slowly back up the tow vehicle so that the hitch ball is
near or aligned under the coupler.
„ Using the jackstand at the front of trailer (tongue), turn
the jackstand crank handle to raise the trailer. If the ball
coupler does not line up with the hitch ball, adjust the
position of the tow vehicle.
Figure D. Ball Hitch Coupling Mechanism
„ Engage the coupler locking mechanism. In the engaged
position, the locking mechanism securely holds the
coupler to the hitch ball.
„ Insert a pin or lock through the hole in the locking
mechanism.
„ Be sure the coupler is all the way on the hitch ball and
the locking mechanism is engaged. A properly engaged
locking mechanism will allow the coupler to raise the rear
of the tow vehicle. Using the trailer jackstand, verify that
you can raise the rear of the tow vehicle by 1 inch after
the coupler is locked to the hitch.
„ Lower the trailer so that its entire tongue weight is held
by the hitch.
„ Raise the jackstand to a height where it will not interfere
with the road.
NOTICE
Overloading can damage the tongue jack. do not
use the tongue jack to raise the tow vehicle more than
one inch.
If the coupler cannot be secured to the hitch ball, do not
tow the trailer. Call your dealer for assistance. Lower the
trailer so that its entire tongue weight is held by the hitch and
continue retracting the jack to its fully retracted position.
„ Open the coupler locking mechanism. Ball couplers have
a locking mechanism with an internal moving piece and
an outside handle. In the open position, the coupler is
able to drop fully onto the hitch ball.

a pintle hitch and pintle coupler for your tow vehicle, where
the load rating of the pintle hitch and pintle coupler is equal
to or greater than that of your trailer.
Also, the pintle hitch size must be the same as the pintle
coupler size. If the hitch is too small, too large, underrated,
loose or worn, the trailer can come loose from the tow
vehicle, and may cause death or serious injury.

If a tire has a bald spot, bulge, cuts, is showing any cords,
or is cracked, replace the tire before towing. If a tire has
uneven tread wear, take the trailer to a dealer service
center for diagnosis.
Uneven tread wear can be caused by tire imbalance, axle
misalignment or incorrect inflation.
Tires with too little tread will not provide adequate tracking
on wet roadways and can result in loss of control, leading
to death or serious injury.
Improper tire pressure causes an unstable trailer and
can result in a tire blowout and loss of control. Therefore,
before each tow you must also check the tire pressure. Tire
pressure must be checked when tires are cold.
Allow 3 hours cool-down after driving as much as 1 mile at
40 mph before checking tire pressure. Trailer tires will be
inflated to higher pressures than passenger vehicle tires.
Since trailer wheels and lug nuts (or bolts) are subjected
to greater side loads than automobile wheels, they are
more prone to loosen. Before each tow, check to make
sure they are tight.
The proper tightness (torque) for lug nuts is listed in the
lug nut tightening section of this manual. Use a torque
wrench to tighten the lug nuts. If you do not have a torque
„ Be sure the pintle hook is inserted completely through

wrench, use a lug wrench (from your tow vehicle) and
tighten the nuts as much as you can. Then have a service
garage or trailer dealer tighten the lug nuts to the proper
torque.
Warning
Metal creep between the wheel rim and lug nuts will
cause rim to loosen and could result in a wheel coming
off, leading to death or serious injury.
Tighten lug nuts before each tow.
Lug nuts are also prone to loosen after first being
assembled. When driving a new trailer (or after wheels
have been remounted), check to make sure they are tight
after the first 10, 25 and 50 miles of driving and before
each tow thereafter.
Failure to perform this check can result in a wheel parting
from the trailer and a crash, leading to death or serious
injury.
Warning
Lug nuts are prone to loosen after initial installation,
which can lead to death or serious injury.
Check lug nuts for tightness on a new trailer or when
wheel(s) have been remounted after the first 10, 25

If additional work items (hoses, tools, clamps etc.) are
going to be added to the trailer, be sure they are distributed
evenly to prevent overloading front to back and side to side.
Heavy items should be placed low and as close to the axle
positions as reasonable. Too many items on one side may
overload a tire.
Excessive loads and/or underinflation cause tire overloading
and, as a result, abnormal tire flexing occurs. This situation
can generate an excessive amount of heat within the tire.
Excessive heat may lead to tire failure. It is the air pressure
that enables a tire to support the load, so proper inflation
is critical. The proper air pressure may be found on the
certification/VIN label and/or on the Tire and Loading
Information placard. This value should never exceed the
maximum cold inflation pressure stamped on the tire.
Improper tire pressure can result in a blowout and loss
of control, which can lead to death or serious injury.
Perform the following steps to determine the load limit of
your trailer.
Be sure tires are inflated to pressure indicated on side
wall before towing trailer.
step 1.
determining load limit of trailer
Determining the load limits of a trailer includes more than
understanding the load limits of the tires alone. On all
trailers there is a Federal certification/VIN label that is
located on the forward half of the left (road) side of the unit.
Locate the statement, “The weight of cargo should never
exceed XXX kg or XXX lbs.,” on your vehicle’s Tire and
Loading Information placard (Figure I). This value equals
the available amount of equipment load capacity.
page 50 — DCA20spxu2 servpro® • operation and parts manual — rev. #0 (09/23/13)
Trailer guidelines
step 2.
Determine the weight of the equipment being loaded
on the tow vehicle. That weight may not safely exceed
the available equipment load capacity. The trailer’s Tire
Information Placard is attached adjacent to or near the
trailer’s VIN (Certification) label at the left front of the trailer
(See Figure I).

„ Improve fuel economy.
„ Increase the tire life.
Use the information contained in this section to make tire
safety a regular part of your vehicle maintenance routine.
Recognize that the time you spend is minimal compared
with the inconvenience and safety consequences of a flat
tire or other tire failure.
step 2.
tire Fundamentals
Determine the combined weight of the driver and
passengers who will be riding in your vehicle.
Federal law requires tire manufacturers to place standardized
information on the sidewall of all tires (Figure I). This
information identifies and describes the fundamental
characteristics of the tire and also provides a tire
identification number for safety standard certification and
in case of a recall.
determining load limit of tow vehicle
step 1.
step 3.
Subtract the combined weight of the driver and passengers
from XXX kilograms or XXX pounds.
step 4.
The resulting figure equals the available amount of cargo
and luggage capacity. For example, if the “XXX” amount
equals 1400 lbs. and there will be five 150 lb. passengers
in your vehicle, the amount of available cargo and luggage
capacity is 650 lbs. (1400-750 (5 x 150) = 650 lbs.).
step 5.
Determine the combined weight of luggage and cargo
being loaded on the vehicle. That weight may not safely
exceed the available cargo and luggage capacity calculated
in Step 4.
If your vehicle will be towing a trailer, load from your trailer
will be transferred to your vehicle. Consult the tow vehicle’s
manual to determine how this weight transfer reduces the
available cargo and luggage capacity of your vehicle.
Studies of tire safety show that maintaining proper tire
pressure, observing tire and vehicle load limits (not carrying
more weight in your vehicle than your tires or vehicle can
safely handle), avoiding road hazards and inspecting tires
for cuts, slashes and other irregularities are the most
important things you can do to avoid tire failure, such as
tread separation or blowout and flat tires. These actions,

month.
„ do not overload tow vehicle. Check the tire information
and loading placard for safe allowable tire loading
conditions.
sidewall should not be repaired. Tires must be removed
from the rim to be properly inspected before being plugged
and patched.
replacing Worn or damaged tires
Replace the tire before towing the trailer if the tire treads
have less than 1/16 inch depth or the telltale bands are
visible. Check inflation pressure weekly during use to insure
the maximum tire life and tread wear. A bubble, cut or bulge
in a side wall can result in a tire blowout. Inspect both side
walls of each tire for any bubble, cut or bulge; and replace
a damaged tire before towing the trailer.
Table B below will help pinpoint the causes and solutions
of tire wear problems.
table B. tire Wear troubleshooting
Wear Pattern
Cause
Solution
Center Wear
Over inflation.
Adjust pressure to particular
load per tire manufacturer.
Edge Wear
Under inflation.
Adjust pressure to particular
load per tire manufacturer.
Side Wear
Loss of camber
or overloading.
Make sure load does not
exceed axle rating.
Align wheels.
Toe Wear
Incorrect toe-in.
Align wheels.
Cupping
Out-of-balance.
Check bearing adjustment
and balance tires.
Wheel lockup and
tire skidding.
Avoid sudden stops when
possible and adjust brakes.
Flat Spots
Warning
ALWAYS wear safety glasses when
removing or installing force fitted parts. DO
not attempt to repair or modify a wheel.
DO NOT install an inner-tube to correct a
leak through through the rim. If the rim is
cracked, the air pressure in the inner tube may cause
pieces of the rim to explode (break off) with great force
and cause serious eye or bodily injury.
tire repair
The proper repair of a punctured tire requires a plug for the
hole and a patch for the area inside the tire that surrounds
the puncture hole. Punctures through the tread can be
repaired if they are not too large, but punctures to the
DCA20spxu2 servpro® • operation and parts manual — rev. #0 (09/23/13) — page 53
Trailer guidelines
Wheel rims
If the trailer has been struck, or impacted, on or near the
wheels, or if the trailer has struck a curb, inspect the rims for
damage (i.e. being out of round); and replace any damaged
wheel. Inspect the wheels for damage every year, even if
no obvious impact has occurred.
3. Check to see if the lug nuts are tight after the first 10,
25 and 50 miles of driving and before each tow
thereafter
Wheels, Bearings and lug nuts
A loose, worn or damaged wheel bearing is the most
common cause of brakes that grab.
To check wheel bearings, jack trailer and check wheels
for side-to-side looseness. If the wheels are loose, or spin
with a wobble, the bearings must be serviced or replaced.
Check inflation pressure weekly during use to insure the
maximum tire life and tread wear. Most trailer axles are
built with sealed bearings that are not serviceable. Sealed
bearings must be replaced as complete units.
Warning
Lug nuts are prone to loosen after initial installation,
which can lead to death or serious injury. Check all
wheel lug nuts periodically.
lug nut torque requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence. See Figure k. DO
NOT torque the wheel lug nuts all the way down.
Tighten each lug nut in 3 separate passes as defined
by Table C.
NOTICE
never use an pneumatic air gun to tighten wheel
lug nuts.
Over-tightening lug nuts will result in breaking the studs
or permanently deforming the mounting stud holes in
the wheels.

lights and signals
Before each tow, check the trailer taillights, stoplights, turn
signals and any clearance lights for proper operation.
Replace any broken or burned-out lamps as necessary.
Check the wire harness for cuts, fraying or other damage.
If it needs replacing, contact your dealer.
Warning
Improper operating taillights, stoplights and turn signals
can cause collisions.
Check all lights before each tow.
