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.

Figure 2. Typical Generator Grounding Application
page 14 — DCA70USI2 60 hz Generator • operation and parts manual — rev. #0 (06/28/11)
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.
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)
b. Aluminum - 6 AWG (8.4 mm2)
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
This 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.

Engine
This generator unit incorporates an ISUZU BJ-4JJ1X diesel
engine. This engine is designed to meet every performance
requirement for the generator. Reference Table 2 for engine
specifications.
In keeping with MQ Power’s policy of constantly improving
its products, the specifications quoted herein are subject
to change without prior notice.
Electric Governor System
The electric governor system controls the RPMs of the engine.
When the engine demand increases or decreases, the
governor system regulates the frequency variation to ±.25%.
Extension Cables
When electric power is to be provided to various tools or
loads at some distance from the generator, extension cords
are normally used. Cables should be sized to allow for
distance in length and amperage so that the voltage drop
between the generator and point of use (load) is held to
a minimum. Use the cable selection chart (Table 6) as a
guide for selecting proper extension cable size.

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.
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.
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

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.

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.
When calculating the power requirements for 3-phase
power use the following equation:
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

WARNING
If adding coolant/antifreeze mix to the
radiator, DO NOT remove the radiator cap
until the unit has completely cooled. The
possibility of hot! coolant exists which can
cause severe burns.
Day-to-day addition of coolant is done from the recovery
tank. When adding coolant to the radiator, DO NOT remove
the radiator cap until the unit has completely cooled. See
Table 12 for engine, radiator, and recovery tank coolant
capacities. Make sure the coolant level in the recovery tank
is always between the “H” and the “L” markings.
Periodic cleaning/replacement is necessary. Inspect it in
accordance with the ISUZU Engine Owner’s Manual.
Fan Belt Tension
A slack fan belt may contribute to overheating, or to
insufficient charging of the battery. Inspect the fan belt for
damage and wear and adjust it in accordance with the

cables are loose. Poor contact may result in poor starting
or malfunctions. Always keep the terminals firmly
tightened. Coating the terminals with an approved battery
terminal treatment compound. Replace battery with only
recommended type battery.
2. Place a small amount of battery terminal treatment
compound around both battery terminals. This will
ensure a good connection and will help prevent
corrosion around the battery terminals.
The battery is sufficiently charged if the specific gravity
of the battery fluid is 1.28 (at 68° F). If the specific gravity
should fall to 1.245 or lower, it indicates that the battery is
dead and needs to be recharged or replaced.
Before charging the battery with an external electric source,
be sure to disconnect the battery cables.

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 14 as a general
maintenance guideline Engine Side (Refer to the Engine
Instruction Manual)
Air Cleaner
Every 250 hours: Remove air cleaner element (Figure 56)
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 56) is attached to the air cleaner.

DCA70USI2 60 hz Generator • operation and parts manual — rev. #0 (06/28/11) — page 37
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 Addition
Add diesel fuel (the grade may vary according to season
and locations).
Removing Water from the Fuel Tank
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 57) wash out any deposits
or debris that have accumulated inside the fuel tank.
Fuel Tank Inspection
In addition to cleaning the fuel tank, the following
components should be inspected for wear:
„„Rubber Suspension — look for signs of wear or
deformity due to contact with oil. Replace the rubber
suspension if necessary.
„„Fuel Hoses — inspect nylon and rubber hoses for signs
of wear, deterioration and hardening.
„„Fuel Tank Lining — inspect the fuel tank lining for signs
of excessive amounts of oil or other foreign matter.
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.

page 38 — DCA70USI2 60 hz Generator • operation and parts manual — rev. #0 (06/28/11)
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 28.
The radiator (Figure 58) 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 58. 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.

Trailer Maintenance
Trailer Maintenance
This section is intended to provide the user with generic
trailer service and maintenance information. The service
and maintenance guidelines referenced in this section refer
to a wide range of trailers.
Remember periodic inspection of the trailer will ensure safe
towing of the generator and will prevent personal injury and
damage to the equipment.
The definitions below describe some of the major
components of a typical trailer that would be used with
generator.
1. Fuel Cell — Provides an adequate amount of fuel for
the equipment in use. Fuel cells must be empty when
transporting equipment.
2. Braking System — System employed in stopping
the trailer. Typical braking systems are electric, surge,
hydraulic, hydraulic-surge and air.
3. GVWR — Gross Vehicle Weight Rating (GVWR) is
the maximum number of pounds the trailer can carry,
including the fuel cell (empty).
4. Frame Length — Measurement is from the ball hitch
to the rear bumper (reflector).
5. Frame Width — Measurement is from fender to
fender
6. Jack Stand — Trailer support device with maximum
pound requirement from the tongue of the trailer.
7. Coupler — Type of hitch used on the trailer for
towing.
8. Tire Size — Indicates the diameter of the tire in
inches (10,12,14, etc.), and the width in millimeters
(175,185,205, etc.). The tire diameter must match the
diameter of the tire rim.
9. Tire Ply — The tire ply (layers) number is rated in
letters; 2-ply,4-ply,6-ply, etc.
10. Wheel Hub — The wheel hub is connected to the
trailer’s axle.
11. Tire Rim — Tires mounted on a tire rim. The tire rim
must match the size of the tire.
12. Lug Nuts — Used to secure the wheel to the wheel
hub. Always use a torque wrench to tighten down the
lug nuts. See Table 18 and FigureFigure 61 for lug nut
tightening and sequence.
13. Axle — Indicates the maximum weight the axle can
support in pounds, and the diameter of the axle
expressed in inches. Please note that some trailers
have a double axle. This will be shown as 2-6000 lbs.,
meaning two axles with a total weight capacity of 6000
pounds.
14. Suspension — Protects the trailer chassis from shocks
transmitted through the wheels. Types of suspension
used are leaf, Q-flex, and air ride.
15. Electrical — Electrical connectors (looms) are provided
with the trailer so the brake lights and turn signals can
be connected to the towing vehicle.
16. Application — Indicates which units can be employed
on a particular trailer.
page 40 — DCA70USI2 60 hz Generator • operation and parts manual — rev. #0 (06/28/11)
Trailer Maintenance
Brakes
Hydraulic Surge Brakes
Trailer brakes should be inspected the first 200 miles of
operation. This will allow the brake shoes and drums to seat
properly. After the first 200 mile interval, inspect the brakes
every 3,000 miles. If driving over rough terrain, inspect the
brakes more frequently.
Figure 59 displays the major hydraulic surge brake
components that will require inspection and maintenance.
Please inspect these components as required using steps
1 through 8 and Table 15 as listed below:
Hydraulic surge brakes (Figure 59) should not require any
special attention with the exception of routine maintenance
such as shoe and lining replacement. Brake lines should
be periodically checked for cracks, kinks, or blockage.
Brake Adjustment
1. Place the trailer on jack stands. Make sure the jack
stands are placed on secure level ground.
2. Check the wheel and drum for free rotation.
3. Remove the adjusting hole cover from the adjusting
slot at the bottom brake backing plate.
4. With a screwdriver or standard adjusting tool, rotate
the star wheel of the adjuster assembly to expand the
brake shoes.
5. Adjust the brake shoes outward until the pressure of
the lining against the wheel drum makes the wheel
difficult to turn.
6. Adjust, rotate the star wheel in the opposite direction
until the wheel rotates freely with slight lining drag.
7. Replace the adjusting hole cover and lower the trailer
to the ground.
8. Repeat steps 1 through 7 on the remaining brakes.
Figure 59. Hydraulic Brake Components
Actuator
Hydraulic surge braking requires the installation of an
actuator at the tongue of the trailer. Remember the surge
or push of the trailer toward the tow vehicle automatically
synchronizes the trailer brakes with the tow vehicle brakes.
As the trailer pushes against the tow vehicle the actuator
telescopes together and applies force to the master cylinder,
supplying hydraulic pressure to the trailer brakes.
Periodically check and test the surge “actuator” to make sure that
it is functioning correctly. Never use an undersize actuator.

Trailer Maintenance
Tires/Wheels/Lug Nuts
Suspension
Tires and wheels are a very important and critical
components of the trailer. When specifying or replacing the
trailer wheels it is important the wheels, tires, and axle are
properly matched.
The leaf suspension springs and associated components
(Figure 60) should be visually inspected every 6,000 miles
for signs of excessive wear, elongation of bolt holes, and
loosening of fasteners. Replace all damaged parts
(suspension) immediately. Torqued suspension components
as detailed in Table 17.
CAUTION
ALWAYS wear safety glasses when
removing or installing force fitted parts.
Failure to comply may result in serious
injury.
CAUTION
DO NOT attempt to repair or modify a
wheel. DO NOT install in inner tube to
correct a leak 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.
Figure 60. Major Suspension Components
