12.3 OPERATIONS AND CHECKS AFTER
STARTING ENGINE
• Emergency stop
If there has been any abnormal actuation or trouble, turn the
starting switch key to the OFF position. The electrical system
and engine will stop. Then contact your Komatsu distributor
for inspection.
• If the work equipment is operated without warming the ma-
chine up sufficiently, the response of the work equipment to
the movement of the control lever will be slow, and the work
equipment may not move as the operator desires, so always
carry out the warming-up operation. Particularly in cold areas,
be sure to carry out the warming-up operation fully.
12.3.1 WHEN NORMAL
NOTICE
• When the hydraulic oil is at a low temperature, do not carry out
operations or move the levers suddenly. Always carry out the
warming-up operation. This will help to extend the machine life.
• Do not suddenly accelerate the engine before the warming-up
operation is completed.
Do not run the engine at low idling or high idling continuously
for more than 20 minutes. This will cause leakage of oil form the
turbocharger oil supply piping.
If it is necessary to run the engine at idling, apply a load from
time to time or run the engine at mid-range speed.
After starting the engine, do not immediately start operations. First,
carry out the following operations and checks.
1. Turn fuel control dial to the center position between LOW IDLING
(MIN) and HIGH IDLING (MAX) and run the engine at medium speed
for about 5 minutes with no load.
2. While running the engine at medium speed, press working mode
switch until the heavy-duty operation mode lamp is turned on.
