PRECAUTIONS FOR MAINTENANCE

WEAM012101
2.8.5 EQUIPMENT
q
The normal or special equipment that must be installed on the
machine or that have been removed must be stored in a safe
place and positioned in such a way as to prevent them from fall-
ing down. If they fall on someone, they may cause serious inju-
ry.
q
When assembling or removing any equipment, make sure that
the ropes and the lifting hook are in good conditions and proper-
ly dimensioned for the load to be lifted.
2.8.6 WORKING UNDER THE MACHINE
q
Before performing service or repairs under the machine, always
lower the work equipment to the ground or in any case lower it
as much as possible.
q
Always secure the tracks so that they cannot move.
q
Do not work under the machine, if this is not sufficiently support-
ed.
2.8.7 CLEANING THE MACHINE
q
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.
q
To clean the machine, use a pressurized jet of warm water or
steam and the specific 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.
q
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 or your Komatsu
Distributor to send you spare plates and change them.
q
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, avoid using water
or steam jets to clean sensors, connectors or the inside of the
cab.
