2.
Check that the red line in the transparent portion of dust in-
dicator (2) does not indicate 7.5 kPa {0.076 kg/cm
If the red line indicates 7.5 kPa {0.076 kg/cm
place the air cleaner element immediately.
For the cleaning method of the element, see "METHOD
FOR CHECKING, CLEANING AND REPLACING AIR
CLEANER (4-15)".

After cleaning or replacing, press the top of dust indicator

METHOD FOR CHECKING ELECTRIC WIRING
•
If fuses are frequently blown or if there are traces of short-circuiting on the electrical wiring,
promptly ask your Komatsu distributor to locate the cause of it and to perform the repair.
•
Keep the top surface of the battery clean and check the vent hole in the battery cap. If it is clogged
with dirt or dust, wash the battery cap with water to clear the vent hole.
NOTICE
In particular, inspect the wiring of "battery", "starting motor", and "alternator" with care.
Perform the following inspection.
•
Perform inspection to confirm that the fuses have no defect and their capacity is proper.
•
Perform inspection to confirm that there is no disconnection or trace of short-circuiting in the electric wiring
and no damage to the coating.
•
Perform inspection to confirm that there is no loose terminals, and tighten any loose parts if found.
•
Always check if there is any accumulation of combustible material around the battery, and remove such
combustible material.
METHOD FOR CHECKING FUEL LEVEL, ADDING FUEL
Do not add any more fuel after the fuel filler gun has automatically stopped when refilling with fuel. If
fuel is excessively added, fuel may expand and flow out when ambient temperature increased. It is dan-
gerous.
Also, it may cause fire. Wipe up the spilled fuel completely.
Fuel is highly flammable, and it is dangerous. Never bring any open flame near fuel.
NOTICE
When restarting the engine that has stopped because of running out of fuel, all air must be sufficiently
bled from the circuit.
For the method of bleeding air, see "METHOD FOR REPLACING FUEL PREFILTER CARTRIDGE (4-56)".
Take care not to cause engine stall because of running out of fuel.
When fuel is used up, you can cut the air bleeding time by filling up the fuel tank with fuel.
