PRECAUTIONS FOR MAINTENANCE

2.8.4 EQUIPMENT

The normal or special equipment that must be installed on the
machine or that have been removed must be stored in safe
places, preventing them from falling down. If they fall on some-
one, they can cause serious bodily harm.
When assemblying or removing any equipment, make sure
that the ropes and the lifting hook are in good conditions and
properly dimensioned for the load to be lifted.

2.8.5 WORKING UNDER THE MACHINE

Always lower the work equipment to the ground or in any case
to its lowest position before performing service or repairs un-
der the machine.
Always lock the machine tracks securely.
Do not work under the machine, if this is not sufficiently sup-
ported.

2.8.6 CLEANING THE MACHINE

Spilled oil or grease, scattered tools or broken pieces are dan-
gerous, because they may cause someone to slip or trip. Al-
ways keep the machine and the work site clean and tidy.
To clean the machine, use a pressurized jet of warm water or
steam and the appropriate detergents available on the market.
Do not use gas oil, oil or solvents, since the former leave an
oily coat that favours the sticking of dust, while the latter (even
if weak) damage the painted surfaces and therefore facilitate
rusting.
While cleaning the machine, keep the pressurized jet at a min-
imum distance of approx. 60 cm in order not to damage the
warning plates and the pictograms.
If the plates are damaged, request Komatsu Utility or your Ko-
matsu Utility Dealer to send you spare plates and change
them.
Water into the electrical system provokes the oxidation of the
contacts and may hinder the start of the machine or even
make it start suddenly and abruptly. For this reason, never use
water or steam jets to clean sensors, connectors or the inside
of the operator's cab.
