SERVICE PROCEDURE
CHECK FUEL SPRAY PREVENTION CAP FOR LOOSENESS AND HARDENING OF RUBBER
The fuel spray prevention caps (12 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 caps, loose bolts or
hardening of the rubber. If there are any problems, the parts must be replaced. In this case, please ask your
Komatsu distributor to carry out replacement.
