3.3.2 AFTER STARTING THE ENGINE
WARNING
q
Emergency stop
If a failure has occurred or an anomaly has been observed, turn the ignition key to position OFF.
q
If the work equipment is operated without warming up the engine sufficiently, the response of the work
equipment to the movements of the control lever will be slow, and the work equipment may not move as
desired by the operator, so always carry out the warming up procedure. Particularly in cold areas, be
sure to carry out the warming up procedure correctly.
3.3.2.1 RUNNING-IN
CAUTION
q
Komatsu machines are adjusted and tested completely before shipment. However, operating the ma-
chine under severe conditions at the beginning can adversely affect the performance of the machine
and shorten its life.
It is advisable to run in the machine for the first 100 hours of operation (as indicated by the hour meter).
During the running-in period, follow the precautions indicated in this manual.
q
After starting the engine, let it idle for 5 minutes.
q
Avoid using the machine with excessive loads and avoid high speeds.
q
Immediately after starting the engine, avoid sudden starts, sudden accelerations, unnecessary sudden stops,
and sudden changes in direction.
3.3.2.2 ENGINE STARTING CAPACITY AND NOISE LEVEL CHECK
When the engine is started, check that this does not cause abnormal noise and that the engine can be simply and
correctly started.
Check also there is no abnormal noise when the engine is in neutral or the speed is slightly increased.
q
If there is abnormal noise when the engine is started and such condition continues, the engine may be damaged.
In such case, contact your Komatsu Distributor as soon as possible to have the engine checked.
3.3.2.3 ENGINE ACCELERATION AND DECELERATION CHECK
Check that engine speed increases gradually when the fuel control lever is set from the minimum neutral position
to the maximum (MAX) speed position after the heating phase.
Check also that the engine speed gradually increases when the fuel control dial is taken to the maximum level
(Max).
q
Carry out a check in a safe place; make sure that safety conditions are present in the surrounding area.
q
When the engine performance is poor at low idle speed and when accelerating and if such condition persist, the
engine may be damaged, the operator has not carry out an operation correctly or braking efficiency has been re-
duced; all these conditions can easily cause an unexpected accident. In such case, contact your Komatsu Dis-
tributor as soon as possible to have the engine checked.
