DCA-500SSK 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.  
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.  
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.  
CAUTION:  
NOTE  
ALWAYS wear safety glasses when removing  
or installing force fitted parts. Failure to comply  
may result in serious injury.

DCA-500SSK GENERAL INFORMATION  
DCA-500SSK FAMILIARIZATION  
Generator  
Open Delta Excitation System  
The DCA-500SSK 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.  
The MQ Power Model DCA-500SSK is a 550 kW generator  
that has been designed as 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.  
There are four leads: A, B, C and D. During light loads, the  
power to the Automatic Voltage Regulator (AVR) is supplied  
from the leads parallel connections of B&C. When loads  
increase, the AVR switches and accepts power from leads  
A&D. The output of leads A&D increase proportionally with  
load. This of adding the voltages to each phase provides  
better voltage response during heavy loads.

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.

DCA-500SSK INSTALLATION  
CAUTION :  
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.  
An electric shock will 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  
The installation site must be free from excessive moisture  
and dust. All electrical equipment must be protected from  
excessive moisture.Failure to do will result in deterioration  
of the insulation and will result in short circuits and  
grounding.  
To prevent electrical shock and possible damage to the  
equipment, it is important to provide a good EARTH ground.  
Article 250 (Grounding) of the National Electrical Code (NEC)  
provides guide lines for proper grounding and specifies the  
cable ground shall be connected to the grounding system of  
the building as close to the point of cable entry as practical.  
Foreign materials such as dust, sand, lint and abrasive  
materials will cause excessive wear to the engine and  
alternator parts.  
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.  
CAUTION :  
a. Copper - 10 AWG (5.3 mm2) or larger.  
b. Aluminum - 8 AWG (8.4 mm2) or larger.  
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.  
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.  
Indoor Installation  
Exhaust gases from diesel engines are extremely  
poisonous. If the generator is installed indoors, the exhaust  
fumes must be vented to the outside.The engine must be  
installed at least two feet from any outside wall. Using an  
exhaust pipe that is too long or too small will cause  
excessive back pressure resulting in engine overheating.  
Eliminate the danger of deadly carbon monoxide gas.  
Exhaust fumes from any diesel engine are very poisonous  
if discharged in a closed room, but harmless if allowed to  
mix with the outside air.  
NOTE  
When connecting the generator  
to any buildings electrical system  
ALWAYS consult with a licensed  
electrician.

DCA-500SSK PRE-SETUP  
General Inspection Prior to Operation  
Circuit Breakers  
The DCA-500SSK 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.  
To protect the generator from an overload, a 3-pole,1400  
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.  
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 8) for selecting proper cable  
size.  
NOTE  
ALWAYS consult with a licensed  
electrician for correct extension  
cord wire size.

Lubrication Oil  
Fill the fuel tank with clean and fresh diesel fuel. DO  
NOT fill the tank beyond capacity.  
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 9 for proper selection of engine oil.  
Pay attention to the fuel tank capacity when replenishing  
fuel. Refer to the fuel tank capacity listed on page 26,  
Specification Table 7.  
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 spillage  
on a hot engine can cause a fire or  
explosion. If diesel spillage occurs,  
wipe up the spilled diesel 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  
An anticorrosion additive added to the water will help  
prevent deposits and corrosion in the cooling system.  
See the engine manual for further details.  
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

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.

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.  
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  
operation, While flushing water through the system,  
watch carefully the water inlet hose does not come out  
of the radiator filler port.  
3. Check the drained oil for excessive metal particles or  
foreign material. Contact the distributor if there is metal  
particles or foreign material.  
4. Using a filter wrench, turn filter cartridge to the left to  
remove it. If the filter cartridge is filled with a large  
amount of oil, wait 10 minutes or so before removing.  
Make sure there is no old gasket stuck on the filter holder.  
7. After flushing, stop the engine, open drain plug and drain  
the water, then close drain plugs.  
8. After draining the water, flush the system with a flushing  
agent. See instructions on flushing agent label.  
5. Tighten drain plug. Clean the filter holder, fill the new  
filter cartridge with clean engine oil, coat the packing  
and thread of the new filter cartridge with engine oil,  
then install it to the filter holder. Tighten until the gasket  
surface contacts the seal surface of the filter holder,  
then tighten it a further 3/4 to 1 turn.  
9. After flushing, open drain plugs and drain out all the  
water, then close drain plugs and add tap water so the  
water level is near the mouth of the water filler.  
10. When the water level is near the mouth of the water  
filler, open drain plugs and start the engine, run at low  
idling and continue to flush the system until clean water  
comes out. Adjust the flow of the water flowing in and  
draining out to ensure the radiator is always full during  
the flushing operation.  
6. Add engine oil through oil filler until the oil level is between  
the H and L marks on the dipstick.  
7. Run the engine at idling for a short time, then stop the  
engine. Recheck the oil level and fill as necessary.  
Replacing fuel filter  
11. When clean water comes out, stop the engine, drain all  
the water, then close drain plugs.  
1. Set the container under the filter cartridge to catch fuel.  
2. Using a filter wrench, turn the filter cartridge to the left  
to remove it.  
12. Remove the corrosion resistor (if equipped) and open  
valve.  
3. Clean the filter holder, fill the new filter cartridge with  
fuel, coat the packing surface of the filter cartridge with  
engine oil, then install the cartridge to the filter holder.  
13. Supply water until it flows over the water filler.  
14. Drain the water inside reserve tank, clean the inside of  
the reserve tank, then fill with coolant/water mixture to  
between the full and low lines.  
4. When installing, tighten until the packing surface  
contacts the seal surface of the filter holder then tighten  
a further 2/3 of a turn. If the filter cartridge is tighten too  
much, the packing will be damaged and will cause fuel  
leakage. Fuel leakage will occur if the filter cartridge is  
not tightened enough. Always tighten to the correct  
angle.  
15. Stop the engine, wait for 3 minutes, add tap water until  
the water level reaches near the water filer port, then  
tighten the radiator cap.  
Check Electric Heater (If equipped)  
Before starting in cold weather (once a year), please contact  
your Komatsu distributor for inspection. Remove electric  
heater from the engine intake manifold and check for  
disconnections or dirt. When checking or installing the electric  
heater, replace the gasket with a new part.
