4.7.3 CHECKS BEFORE STARTING
4.7.3.a VARIOUS CHECKS
4.7.3.b CHECKING THE COOLANT LEVEL
DANGER
• Dirt, oil and fuel spread in the engine compartment near the hot areas may cause fires and damage the
machine.
Check if there are leakages frequently and carry out the necessary repairs immediately; if this occurs
repeatedly, contact your Komatsu Utility Dealer.
Before starting the engine, check:
1. if there are loose screws or nuts;
2. if there are oil, fuel or coolant leakages;
3. if the work equipment is worn;
4. the track tension and wear;
5. the conditions and efficiency of the instruments and warning lights on the dashboard, of the acoustic alarm, of
the working lights and of the horn.
The other general checks concern safety, and precisely:
6. soundness of the safety belt;
7. soundness and legibility of the warning plates;
8. cleanliness of the handles used to reach the driver’s seat, cleanliness inside the driver’s cab.
DANGER
• Do not remove the radiator cap; the coolant must be
checked with cold engine, through the compensation
tank.
The coolant tank (1) can be reached after opening the engine
hood and the coolant level must be included between the LOW
and FULL marks.
If necessary, add water or coolant and, if a constant and consid-
erable decrease in the coolant level can be noticed, check the
tightness of the engine-radiator unit and of the radiator body.
