2.8.5 WORKING UNDER THE MACHINE
2.8.6 KEEPING THE MACHINE CLEAN
RWA01320
•
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 cables and the lifting hook are in good conditions and prop-
erly dimensioned for the load to be lifted.
RWA02520
•
Always lower the work equipment to the ground or in any case
to its lowest position before performing service or repairs under
the machine.
•
Always lock the machine tracks securely.
•
Do not work under the machine, if this is not sufficiently support-
ed.
RWA01330
•
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 diesel 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 rust-
ing.
•
While cleaning the machine, keep the pressurized jet at a mini-
mum 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.
