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.

Figure 30. Double Fuel Tank System
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.
