Check that the yellow piston shown in dust indicator (3)
display does not enter the red (7.5 kPa {0.08 kg/cm
sition.
If the yellow piston has entered the red (7.5 kPa
2
{0.08 kg/cm }) position, clean or replace the air cleaner el-
ement immediately.

5.
After cleaning and replacing, push the button of the dust
indicator (3).
The yellow piston returns.
In an environment where the rubber is deteriorated or the
surface is damaged easily (in the direct sunlight, sandy
district, etc.), replace it before reading becomes difficult
because of dirt.
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.
