OPERATIONS, CHECKS AFTER STARTING ENGINE

WARMING-UP OPERATION
NOTICE
Avoid accelerating the engine suddenly before the warming-up operation is completed.
Do not run the engine for more than 20 minutes at low idling or high idling.
If it is necessary to idle the engine, apply a load from time to time or run at a mid-range speed.
On machines equipped with auto emergency steering, if the machine is not fully warmed up, the emergency steering may be
actuated momentarily when the parking brake switch is set to TRAVEL or the dump control lever is operated.
After the engine starts, do not start operating the machine immediately. First, perform the following operations and
checks.
1. After starting the engine, run the engine at low idle for 5 minutes for warming up operation.
2. After the warming-up operation, check that the machine monitor is normal.
If there is any problem, carry out maintenance or repair.
When the AISS LOW switch is at the AUTO position and the engine coolant temperature is still low, high idle
revolution is automatically maintained.
3. Check if there is no problem in the steering operation, flashing of lights, sound of horn, exhaust gas color, noise,
or vibration. If any problem is found, repair it.
Immediately after the engine is started, if the steering oil temperature is low, the steering will be slightly heavy,
so avoid traveling at high speed.
If there are any problems, please ask your Komatsu distributor to carry out adjustment and repairs.
