PRECAUTIONS FOR MAINTENANCE
52
WEAM009300
2.8.7 USE OF THE ENGINE DURING MAINTENANCE
q
During maintenance operations, make the engine run only when indispensable. If it is necessary to have the
engine running (for example, to wash the cooling circuit or to check the functionality of the alternator), an
operator should constantly remain in the cab, in order to be able to stop the engine whenever necessary.
q
During maintenance operations with running engine, do not release the control locking devices from the “locked”
position or change the position of the travel levers.
Maintenance staff must not move any control lever.
q
When carrying out maintenance operations, do not touch the moving parts of the machine and avoid wearing
large and loose clothes.
2.8.8 PERIODICAL CHANGE OF THE PARTS THAT ARE CRITICAL FOR
SAFETY
q
Periodically change the following parts, which are important to prevent fires.
Fuel system: fuel delivery and return pipes.
Hydraulic system: main delivery pipes of the hydraulic pump.
q
Even if they seem to be in good conditions, these components must be periodically changed with new ones. In
fact, these components tend to deteriorate over time.
q
If one of these parts is defective, change or repair it even if the prescribed change interval has not elapsed yet.
(See "4.7 PERIODICAL CHANGE OF SAFETY-RELATED COMPONENTS").
2.8.9 STOP THE ENGINE BEFORE
CARRYING OUT ANY
MAINTENANCE OPERATION OR
INSPECTION
q
Stop the machine only on firm and level ground and stop the
engine before carrying out any maintenance operation or
inspection.
q
If it is necessary to have the engine running during
maintenance, shift the safety lever (1) to the “locked” position
(L) and carry out any maintenance operation with the help of
another person; one operator must remain on board and the
words to be used during the operation must be agreed upon in
advance.
q
The person who carries out the maintenance operation must be
very careful not to touch any moving part of the engine.
