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 re-
peatedly, 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: instruments and warning lights on the dashboard, acoustic alarm, working
lights, windshield wiper and 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 expansion tank.
The coolant tank (1) can be reached after opening the engine
hood: the coolant level in the tank must be included between the
MIN. and MAX. marks.
If necessary, add water or coolant and, if a constant and consider-
able decrease in the coolant level can be noticed, check the tight-
ness of the radiator-engine unit and of the radiator casing.
