OPERATION

CHECKS AFTER STARTING ENGINE

CHECK PARKING BRAKE
Check that the parking brake works properly.
If there is any abnormality in the operation of the parking brake or the brake does not provide the proper braking
effect, please contact your Komatsu distributor for adjustment.
CHECK BRAKE PEDAL
Set to the machine on level ground with no obstacles in the surrounding area, then drive the machine slowly forward
and in reverse and check the braking effect of the brakes.
If there is any abnormality in the operation of the brakes, please ask your Komatsu distributor to carry out
adjustment.
CHECK TRAVEL OF BRAKE PEDAL
Depress the brake pedal fully and check the distance from the floor. Check that the pedal is not too close to the floor
and that there is no abnormal feeling when operating the brake pedal.
If any abnormality is found, please ask your Komatsu distributor to carry out adjustments.
CHECK FOR EASE OF STARTING ENGINE, ABNORMAL NOISE
When starting the engine, check that the engine causes no abnormal noise and that it starts up easily and smoothly.
Check also that there is no abnormal noise when the engine is idling or when the revolution rises slightly.
When there is an abnormal noise at the engine startup and if that condition continues, the engine may be
damaged. In that case, ask your Komatsu distributor to check the engine as soon as possible.
CHECK ENGINE AT LOW SPEED AND WHEN ACCELERATING
Check that there is no irregularity in the engine speed and that the engine does not suddenly stop when the machine
is stopped during normal travel.
Check also that the engine accelerates smoothly when the accelerator pedal is depressed.
Carry out the inspection in a safe place and check that there is no one in the surrounding area.
If the condition at low speed or when accelerating is extremely poor and that condition continues, there is danger
that the engine may be damaged, that the operating feeling may become strange, that the braking effect may
deteriorate, or that an unexpected accident may happen, so please ask your Komatsu distributor to carry out
repairs as soon as possible.
CHECK LOCATION OF ABNORMALITIES FROM PREVIOUS DAYS
Check the places where problems occurred when using the machine on previous days.
If any abnormality is found, please contact your Komatsu distributor for inspection and repair.
