USE OF THE MACHINE AND RELATED CONTROLS
CHECKING AND CLEANING THE WATER SEPARATOR
Fuel is flammable; do not use naked flames and do not
q
smoke while draining the water separator.
If fuel is spilled, wipe it up immediately.
q
If the red ring (1) of the water separator is on the bottom of the
casing (2), this means that there is no water.
If the ring (1) is floating, this means that there is water up to its
lower surface, therefore drain the water by proceeding as follows.
1 - Open the radiator cover and turn the lever (3) to the "locked"
position (A). (For details, see "3.2.7 RADIATOR COVER").
2 - With a filter wrench, loosen the metal ring (4), remove the
casing (2) and eliminate the water contained inside it.
3 - Put back the casing (2) and tighten the metal ring (4).
4 - Turn the lever (3) to the "open" position (B).
5 - Drain any water or sediment from the fuel tank. For further
details, see "4.9.1.d DRAINING THE FUEL TANK".
CHECKING THE WIRING SYSTEM
If fuses are corroded, rusted or do not hold well in place, replace them with fuses featuring the same rat-
q
ing; before replacing a fuse, make sure that both the starter key and the battery main switch are turned
to OFF.
If the wirings show traces of short circuits, contact your Komatsu Distributor, who will locate the fault
q
and carry out any necessary repairs.
Before checking the wiring, take all the necessary safety precautions.
q
Always keep the battery surface clean and make sure that the charge level warning light is always visi-
q
ble.
Make sure that the fuses are not damaged, that fuses with the required capacity are used, that there are no dis-
connected, broken, or short-circuited wires; furthermore, check the terminals, and tighten any loose ones.
Check the wiring of the battery, the starter and the alternator carefully.
In addition, remove any flammable material that may have accumulated around the battery.
For troubleshooting and repairs, contact your Komatsu Distributor.
