SAFETY MAINTENANCE INFORMATION
q
There is a hazard that high-pressure oil leaking from small
holes may penetrate your skin or cause blindness if it con-
tacts your eyes directly. If you are hit by a jet of high-pres-
sure oil and suffer injury to your skin or eyes, wash the place
with clean water, and consult a doctor immediately for medi-
cal attention.
PRECAUTION FOR HIGH FUEL PRESSURE
High pressure is generated inside the engine fuel piping when the engine is running. When carrying out inspection
or maintenance of the fuel piping system, wait for at least 30 seconds after stopping the engine to let the internal
pressure go down before starting inspection or maintenance.
SAFETY HANDLING HIGH-PRESSURE HOSES
q
If oil or fuel leaks from high-pressure hoses, it may cause fire or defective operation, which may lead to serious
injury. If any loose bolts are found, stop work and tighten to the specified torque. If any damaged hoses are
found, stop operations immediately and contact your Komatsu distributor.
Replace the hose if any of the following problems are found.
q
Damaged or leaking hydraulic fitting.
q
Frayed or cut covering or exposed reinforcement wire layer.
q
Covering swollen in places.
q
Twisted or crushed movable portion.
q
Foreign material embedded in covering.
PRECAUTION FOR HIGH VOLTAGE
When the engine is running or immediately after it has stopped,
high voltage is generated at the injector terminal and inside the
engine controller, so there is danger of electrocution. Never
touch the injector terminal or the inside of the engine control-
ler.
If it is necessary to touch the injector terminal or the inside of
the engine controller, please contact your Komatsu distributor.
