DCA-180SSK — TOWING
Towing Safety Precautions
CAUTION:
Check with your county or state safety
towing regulations department before
towing your generator.
To reduce the possibility of an accident while transporting
the generator on public roads, always make sure the trailer
(Figure 1) that supports the generator and the towing vehicle
are in good operating condition and both units are
mechanically sound.
The following list of suggestions should be used when towing
your generator:
■ Make sure the hitch and coupling of the towing vehicle
are rated equal to, or greater than the trailer "gross vehicle
weight rating" (GVWR).
■ ALWAYS inspect the hitch and coupling for wear. NEVER
tow a trailer with defective hitches, couplings, chains
etc.
■ Check the tire air pressure on both towing vehicle and
trailer. Also check the tire tread wear on both vehicles.
■ ALWAYS make sure the trailer is equipped with a "Safety
Chain".
■ ALWAYS attach trailer's safety chain to bumper of towing
vehicle.
■ ALWAYS make sure the vehicle and trailer directional,
backup, brake, and trailer lights are connected and working
properly.
■ Remember the maximum speed unless otherwise posted for
highway towing is 45 MPH. Recommended off-road towing
is not to exceed 10 MPH or less depending on type of terrain.
■ Place chocked blocks underneath wheel to prevent rolling,
while parked.
■ Place support blocks underneath the trailer's bumper to
prevent tipping, while parked.
■ Use the trailer's hand winch to adjust the height of the trailer,
then insert locking pin to lock wheel stand in place, while
parked.
■ Avoid sudden stops and starts. This can cause skidding, or
jackknifing. Smooth, gradual starts and stops will improve
gas milage.
■ Avoid sharp turns to prevent rolling.
■ Remove wheel stand when transporting.
■ DO NOT transport generator with fuel in tank.

If your trailer has a braking system, the 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.
Before any brake synchronizations adjustments can be made,
the trailer brakes should be burnished-in by applying the
brakes 20-30 times with approximately a 20 m.p.h. decrease
in speed, e.g. 40 m.p.h. to 20 m.p.h. Allow ample time for
brakes to cool between application. This allows the brake
shoes to slightly be seated into the brake drum surface.
Electric Brakes
Electrically actuated brakes (Figure 2) are similar to hydraulic
brakes. The basic difference is that hydraulic brakes are
actuated by an electromagnet.
Listed below are some of the advantages that electric brakes
have over hydraulic brakes:
 Brake system can be manually adjusted to provide the
corrected braking capability for varying road and load
conditions
 Brake system can be modulated to provide more or less
braking force, thus easing the brake load on the towing
vehicle
 Brake system has very little lag time between the time
the vehicle’s brakes are actuated and the trailer’s brakes
are actuated
 Brake system can provide an independent emergency
brake system
Figure 2 displays the major electric brake components that
will require inspection and maintenance. Please inspect these
components as required.
Electric 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. Rotate the star wheel in the opposite direction until the
wheel rotates freely with slight lining drag.
Remember in order to properly synchronize the tow vehicle’s 7. Replace the adjusting hole cover and lower the trailer to
the ground.

Hydraulic/Air/Surge Brakes
Hydraulic brakes (Figure 3) should not require any special
attention with the exception of routine maintenance such as
shoe and lining replacement. These brakes can be adjusted
in the same manner as electric brakes. Brake lines should
be periodically checked for cracks, kinks, or blockage.
Figure 3 below displays the major hydraulic/air/surge brake
components that will require inspection and maintenance.
Please inspect these components as required using steps 1
through 6 as referenced in the electric brake adjustments

DCA-180SSK — TRAILER SAFETY GUIDELINES
Tires/Wheels/Lug Nuts
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.
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.
Tire Wear/Inflation
Tire inflation pressure is the most important factor in tire life.
Pressure should be checked cold before operation DO NOT
bleed air from tires when they are hot. Check inflation
pressure weekly during use to insure the maximum tire life
and tread wear.
Table 2 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.
Suspension
The leaf suspension springs and associated components
(Figure 4) 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 3.
CAUTION:
NOTE
ALWAYS wear safety glasses when removing
or installing force fitted parts. Failure to comply
may result in serious injury.

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 5. DO NOT
torque the wheel lug nuts all the way down. Tighten
each lug nut in 3 separate passes as defined by Table 4.
3. After first road use, retorque all lug nuts in sequence.
Check all wheel lug nuts periodically.

Microprocessor Controlled Alarm System
The DCA-180SSK generator is equipped with various alarms
and LED status indicators. These alarms and status indicators
are provided to add safety to the generator when operating
under normal conditions. The DCA-180SSK generator is
designed to shutdown in the event of low oil, high coolant
temperature, low battery and other operation conditions that
may cause severe damage to the generator.
Open Delta Excitation System
The DCA-180SSK generator is equipped with the state of
the art "Open-Delta" 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: A, B, C and D. During steady
loads, the power to the Automatic Voltage Regulator (AVR)
is supplied from the parallel connections of A to B, A to D,
and C to D. These three phases are rectified and are used as
the current for the exciter section.
During a heavy load, such as motor starting, the AVR
switches the configuration of the Open-Delta to the series
connection B to C. This has the effect of adding the voltages
of each phase to provide better voltage response during heavy
loads.
The connections of the AVR to the AC output windings are
for the sole purpose of sensing. No power is required from
these windings.
The open-delta design provides virtually unlimited excitation
current due to its independent power supply offering maximum
motor starting capabilities. The excitation does not have a
"fixed ceiling" and responds according the demands of the
required load.
PAGE 26 — DCA-180SSK — PARTS AND OPERATION MANUAL — REV. #3 (06/11/09)
DCA-180SSK — GENERAL INFORMATION (OPTIONS)
Engine
The DCA-180SSK is powered by a 4 cycle, water cooled,
turbocharged KOMATSU Model SA6D108E-2 diesel gasoline
engine. This engine is designed to meet every performance
requirement for the generator. Reference Table 7, page 25
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.
The basic controls and indicators for the DCA-180SSK
generator are addressed on the following pages.
Mechanical Governor System
The mechanical governor system control the RPM of the
engine. When the engine demands increase or decrease,
the mechanical governor system regulates the frequency
variation to ±1.0%. The electronic governor option
increases frequency variation to ±0.25%.
Electronic Governor System
The electronic governor system is made up of two parts, an
electronic controller that monitors frequency variation as the
load increases and decreases and an electronic actuator
that controls the engine throttle. The frequency is regulated
at ±0.25 to help protect sensitive equipment.
CAUTION :
ALWAYS unplug the jacket water heater
before servicing.
There is a bleed screw on the valve on the engine block.
After service of either the heater or the cooling system, it is
possible to create an air bubble in this area. The air bubble
would prevent hot water created by the jacket water heater
from circulating, if the air bubble were not allowed to escape.
This bleed screw allows for the bleeding process to be
accomplished.
Battery Charger (OPTIONAL)
The battery charger will operate in a ‘BOOST’ mode until
the battery’s current acceptance falls to 70% of the
charger’s rating. The charger will then go into a ‘FLOAT’
mode, where it discharges a lower voltage until an AC
failure, or the battery is discharged.
Fuel Water Separator
The fuel water separator separates water mixed in the
fuel. It has an indicator to let the operator know to drain
the water. See maintenance section for instructions how
to drain water from separator.
Jacket Water Heater (OPTIONAL)
The jacket water heater is a 1500-watt heater designed to
keep the coolant from freezing in the engine block. The
heater is thermostatically controlled and once an acceptable
engine temperature is achieved it will cycle on and off,
operating only about 1/3 of the time. This becomes a very
energy efficient option compared to a direct immersion block
heater. It is designed to keep the engine between 100 and
120 degrees Fahrenheit. This is not a throwaway heater. It
is completely serviceable.
In normal conditions, 20 to 15 minutes is all that is required
to raise the engine temperature of a cold engine to 100
degrees Fahrenheit.

DCA-180SSK — INSTALLATION
Outdoor Installation
Install the generator in a location where it will not be exposed
to rain or sunshine. 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 the exhaust will not be
discharged in the direction of nearby homes.
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.
CAUTION :
An electric shock may happen when
vibrators are used. Pay close attention
to handling when operating vibrators and
always use rubber boots and gloves to
insulate the body from electrical shock.
Generator Grounding
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to the
engine parts and the alternator.
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.
CAUTION :
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
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.
1. Use one of the following wire types to connect the
generator to earth ground.
a. Copper - 10 AWG (5.3 mm2) or larger.
b. Aluminum - 8 AWG (8.4 mm2) or larger.
2. When grounding the generator (Figure 27) 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.
NOTE
When connecting the generator to
any buildings electrical system
ALWAYS consult with a licensed
electrician.

General Inspection Prior to Operation
Circuit Breakers
The DCA-180SSK generator has been thoroughly inspected
and accepted prior to shipment from the factory. However,
be sure to check for damaged parts or components, or loose
nuts and bolts, which could have occurred in transit.
Extension Cable
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 Guide (Table 10)
as a guide for selecting proper cable size.
To protect the generator from an overload, a 3-pole, 500 amp,
main circuit breaker is provided to protect the UVW output
terminals from overload. In addition two single-pole, 20 amp
GFCI circuit breakers are provided to protect the GFCI
receptacles from overload. Three 50 amp load circuit breakers
have also been provided to protect the load side of the
generator from overload. Make sure to switch ALL circuit
breakers to the "OFF" position prior to starting the engine.
NOTE
ALWAYS consult with a licensed
electrician for correct extension
cord wire size.

Lubrication Oil
Fuel
Fill the engine crankcase with lubricating oil through the filler
hole, but do not overfill. Make sure the generator is level.
With the dipstick inserted all the way, but without being screw
into the filler hole, verify that the oil level is maintained
between the two notches (Figure 28) on the dipstick. See
Table 11 for proper selection of engine oil.
Pay attention to the fuel tank capacity when replenishing
fuel. Fill the fuel tank with clean and fresh diesel fuel. DO
NOT fill the tank beyond capacity.
The fuel tank cap must be closed tightly after filling. Handle
fuel in a safety container. If the container does not have a
spout, use a funnel. Wipe up any spilled fuel immediately.
CAUTION :
Never fill the fuel tank while the engine is
running or in the dark. Diesel fuel spillage
on a hot engine can cause a fire or
explosion. If diesel fuel spillage occurs,
wipe up the spilled fuel completely to
prevent fire hazards.
Coolant
Use only drinkable tap water. If hard water or water with
many impurities is used, the inside of the engine and radiator
may become coated with deposits and cooling efficiency
will be reduced.
Figure 28. Engine Oil Dipstick
When checking the engine oil, be sure to check if the oil is
clean and viscous. If the oil is not clean, drain the oil by
removing the oil drain plug, and refill with the specified amount
of oil as outlined in the Komatsu Engine Owner's Manual.
An anticorrosion additive added to the water will help prevent
deposits and corrosion in the cooling system. See the engine
manual for further details.

Battery Cable Installation
ALWAYS be sure the battery cables (Figure 30) are properly
connected to the battery terminals as shown below. The
RED cable is connected to the positive terminal of the battery,
and the BLACK cable is connected to the negative terminal
of the battery.
CAUTION :
Inadequate battery connections may cause
poor starting of the generator, and create
other malfunctions.
Wiring
Inspect the entire generator for bad or worn electrical wiring
or connections. If any wiring or connections are exposed
(insulation missing) replace wiring immediately.
Piping and Hose Connection
Inspect all piping, oil hose, and fuel hose connections for
wear and tightness. Tighten all hose clamps and check hoses
for leaks.
Figure 30. Battery Connections
CAUTION :
If the battery cable is connected
incorrectly, electrical damage to the
generator will occur. Pay close attention
to the polarity of the battery when
connecting the battery.
When connecting battery do the following:
1. DO NOT connect the battery cables to the battery
terminals when the Off/Manual/Auto switch is in either
the manual or auto position (ON). ALWAYS make sure
that the Off/Manual/Auto switch is in the OFF position
when connecting the battery..
If any hose (fuel or oil) lines are defective replace them
immediately.
Battery
This unit is of negative ground DO NOT connect in reverse.
Always maintain battery fluid level between the specified
marks. Battery life will be shortened, if the fluid level is not
properly maintained. Add only distilled water when
replenishment is necessary.
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 the battery is
discharged and needs to be recharged or replaced.
Check to see whether the battery cables are loose. Poor
contact may result in poor starting or malfunctions. Always
keep the terminals firmly tightened. Coating the terminals
with a thin film of grease will help inhibit corrosion.
2. Place a small amount of grease around both battery
terminals. This will ensure a good connection and will
help prevent corrosion around the battery terminals.

DCA-180SSK — LOAD APPLICATION
CAUTION:
Single Phase Load
Motors and motor-driven equipment draw
much greater current for starting than
during operation.
Always be sure to check the nameplate on the generator
and equipment to insure the wattage, amperage and
frequency 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.
NOTE
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 14

WARNING:
The engine's exhaust contains harmful
emissions. ALWAYS ventilate the
exhaust when operating inside tunnels,
excavations or buildings. Direct exhaust
away from nearby personnel.
Before Starting
Engine
1. Check the lubricating oil level prior to starting the engine.
Make sure the generator is level. The oil level must be
maintained between two notches on the dipstick.
2. When there is not enough lubricating oil, fill the crankcase
with high grade motor oil. Use a high quality detergent
oil classified CC or higher (See Table 9 on page 39).
3. Check the coolant level in the radiator and subtank.
Replenish with antifreeze as necessary. Always maintain
the coolant level between the FULL and LOW markings
on the coolant container. Be sure the radiator cap is
fastened securely.
4. Check the fuel level on the fuel gauge. If fuel is low, fill
the fuel tank with clean fresh diesel fuel. If fuel spillage
occurs, completely wipe up the spilled fuel immediately.
Before Starting
Generator and Control Panel
CAUTION:
 NEVER start the engine with the
main, GFCI or load circuit breakers
in the ON position.
1. Be sure to disconnect the electrical load and switch the
main, load and G.F.C.I. circuit breakers (Figure 31) to
the “OFF” position prior to starting the engine.
Jacket Water Heater and Internal Battery Charger 120
VAC Output Receptacles (OPTIONAL)
This generator is equipped with two 120 VAC, 20 amp output
receptacles located on the output terminal panel, page 35
Figure 14.
The purpose of these receptacles is to provide power via
commercial power to the jacket water heater and internal
battery charger.
These receptacles will ONLY function when commercial
power has been supplied to them (Figure 32). To apply
commercial power to these receptacles, a power cord of
adequate size will be required.
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 an power cord of
adequate size.
When connecting the generator to a isolation (transfer)
switch, ALWAYS have power applied to the generator's
internal battery charger. This will ensure that the engine will
not fail due to a dead battery.
CAUTION:
ALWAYS have power applied to the
generator's internal battery charger when
connecting the generator to a isolation
(transfer) switch. Remember before
connecting this generator to any buildings
electrical system, have a licensed electrician
perform the installation of the transfer switch.

DCA-180SSK — MAINTENANCE
General Inspection
Prior to each use, the generating set should be cleaned and
inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts or other fasteners. Also check for fuel
or oil leaks.
Air Cleaner
Every 50 hours: If dust indicator is red, clean the air cleaner
element.
Outer Element:
1. Loosen wing bolt, remove dust cup, then remove wing
nut and take out element.
2. Clean the inside of the body and cover using a damp
cloth.
3. Blow dry with compressed air (0.69Mpa {7kgf.cm2,
99.4 PSI} maximum against the side of the element
along the pleats. Then blow dry against outside along
the pleats, then against inside again.
4. Remove one seal each time the element is cleaned.
5. Replace the outer element after cleaning it 6 times or
after one year. Replace the outer element if indicator is
red even after cleaning it.
6. Check the inner cylinder element clamping nut for
looseness, and retighten if necessary.
7. If seal washer is damaged or the threads of wing nut are
damaged, replace.
8. Remove evacuator valve and clean it with compressed
air. Reinstall.
Inner element (if equipped)
1. Remove the cover and outer element, then remove the
inner element.
2. Cover the air connector opening (outer side) with clean
cloth or cloth tape.
3. Clean the inside of the body. Remove air connector
opening protection.
4. Install a new inner cylinder element to the cylinder and
tighten the nut.
5. Install element.
6. After replacing the element, press the button of the dust
indicator to return the red piston to its original position.
Fuel Addition
Add diesel fuel (the grade may vary according to season
and locations). Always pour through the mesh filter.
Removing Water from the Tank
After prolonged use, water and other impurities accumulate
in the bottom of the tank. Occasionally remove the drain
cock and drain the contents. During cold weather, the greater
the empty volume inside the tank, the easier it is for water to
condense. This can be reduced by always keeping the tank
as full as possible.
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.
To restart after running out of fuel, turn the key switch to the
“START” position for 15-30 seconds. Try again, if needed.
This unit is equipped with an automatic air bleeding system.
Service Daily
If engine is operating in very dusty and dry grass conditions,
a clogged air cleaner will result in high fuel consumption,
loss of power and excessive carbon buildup in the
combustion chamber.
Cleaning the Fuel Strainer
Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in diesel. Securely
fasten the fuel strainer cap so that fuel will not leak. Check
the fuel strainer every 200 hours of operation or once a month.
Check Oil Level
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, page 43.
Flushing Out Radiator and Changing Coolant
1. Stop the engine and allow to cool. Tighten valve of the
corrosion resistor (if equipped).
2. Turn water filer cap slowly and remove it.
3. Prepare a container to catch the coolant, then open drain
plug of the radiator or heat exchanger and drain plug of
the engine, and drain the coolant.
4. After draining the coolant, close drain plugs and fill with
tap water.
PAGE 54 — DCA-180SSK — PARTS AND OPERATION MANUAL — REV. #3 (06/11/09)
DCA-180SSK — MAINTENANCE
5. When the water level is near the mouth of the water
filler, open drain plugs and start the engine, and run at
low idling. Keep the engine running at low idling and
flush the radiator for about 10 minutes.
Changing Oil
1. Make sure the oil is cool before changing.
2. Set a container directly under the drain plug of the oil
pan. Loosen the drain plug slowly.
6. Adjust the flow of the water flowing in and draining out to
ensure that the radiator is always full during the flushing 3. Check the drained oil for excessive metal particles or
