Circuit Breakers
To protect the generator from an overload, a 3-pole, 800 amp,
main circuit breaker is provided to protect the UVWO 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 auxiliary receptacles
from overload. Make sure to switch ALL circuit breakers to
the "OFF" position prior to starting the engine.
Lubrication Oil
Fill the engine crankcase with lubricating oil through the filler
hole, but DO NOT overfill. Make sure the generator is level.
Also verify that the oil level is maintained between the two
notches (Figure 29) on the dipstick. See Table 11 for proper
selection of engine oil.
Figure 29. Engine Oil Dipstick
When checking the engine oil, be sure to check if the oil is
clean. 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. Oil should be
warm before draining.
Other types of motor oils may be substituted if they meet
the following requirements:

Fuel Check
DANGER - EXPLOSION/FIRE HAZARDS
Fuel spillage on a hot engine can cause a fire or explosion .
If fuel spillage occurs, wipe up the spilled fuel completely
to prevent fire hazards. NEVER smoke around or near the
generator.
REFILLING THE FUEL SYSTEM
The DCA300SSK series generators may (if equipped with a
trailer or skid) have a double fuel tank system (Figure 30),
which consists of an internal generator fuel tank, and a
trailer mounted fuel tank. It is also possible the generator
can be equipped with a skid mounted fuel tank (Figure 31).
The skid type fuel system does not use the internal generator
fuel tank.
Use the instructions in this section that applies to your type
of fuel tank system.
ALWAYS fill the fuel tank with clean and fresh #2 diesel
fuel. DO NOT fill the fuel tanks beyond their capacities.
Pay attention to the fuel tank capacity when replenishing
fuel. 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 - REFUELING THE GENERATOR
ONLY properly trained personel who have read and
understand this section should refill the fuel tank system.
