4.7.2 MAINTENANCE EVERY 10 HOURS OF OPERATION OR EVERY DAY
4.7.2.a VARIOUS CHECKS
DANGER
• Dirt, oil and fuel in the engine compartment near hot parts may damage the machine and even cause
fires.
Check frequently and eliminate any leakage; if leakages occur repeatedly, contact your Komatsu Utility
Dealer.
Before starting the engine, proceed as follows:
1.
Verify that the boom inclination indicator pendulum is free to rotate and reach the end of the scale and that it
returns to its original position, performing the necessary adjustment swings, once it has been released.
2. Check for loose screws or nuts.
3. Check for oil, fuel or coolant leakages.
4. Check for unusual wear, deformation or cracks.
5. Check the condition of the rims and the condition and wear of the tyres.
6. Make sure that lights, work lights and direction indicators work correctly.
The other general checks concern the safety of the operator and he is required to:
7. Check the soundness of the safety belt.
8. Check the soundness and legibility of the warning plates.
9. Make sure that the ladders and handles used to reach the driver’s seat are clean, as well as the inside of the
cab.
4.7.2.b CHECKING THE ACOUSTIC ALARMS, WARNING LIGHTS AND INSTRUMENTS
This checking procedure concerns three units:
1 -
Acoustic alarm and warning lights on the dashboard: this check is performed by turning the ignition key to
position “ I ”. In this condition, the red warning lights on the dashboard should come on and the acoustic alarm
should start sounding.
If a red warning light remains off, this means that the corresponding function is not active; before using the
machine, check the circuit concerned and eliminate the fault.
2 - Sli-Safe Load Indicator: the procedure consists in checking that all the LEDs of the device come on when
the ignition key is turned to position “ I ”. Furthermore, an additional test is necessary and should be carried out
halfway through the work shift.
The additional test consists in pressing the TEST button (see «3.2.5 MACHINE CONTROLS» 7 - SLI-SAFE
LOAD INDICATOR) and checking that the LEDs come on and that the acoustic alarm sounds.
3 - Instruments: the instruments should be checked during the warming up of the machine and the first travel
movements.
More specifically, the following checks can be performed during warming up: coolant thermometer, engine
revolution counter and fuel level indicator.
The correct operation of the speedometer can be checked during travel.
