METHOD FOR CHECKING FOR MISSING FUEL SPRAY PREVENTION CAP,
HARDENING OF RUBBER
The fuel spray prevention caps (10 places) on the fuel injection piping and both ends of the high-pressure piping
act to prevent the fuel from coming into contact with high-temperature parts of the engine and causing a fire if
the fuel should leak or spray out.
Check visually and touch by hand to check that there are no missing fuel spray prevention cap, loose bolts or
hardening of the rubber.
Replacement is required if any trouble is found. Ask your Komatsu distributor for that work.
METHOD FOR REPLACING RADIATOR CAP
WARNING
Immediately after the engine is stopped, the coolant is still hot and the pressure is accumulated in the
radiator. If the cap is removed under this condition and the coolant is drained, it may cause burn. Al-
ways wait for the temperature to go down, and turn the cap slowly to release the pressure.
1.
Place the machine on a level ground, then stop the engine.
2.
Open the engine hood (1).
