Use Of The Engine During Maintenance; Periodical Change Of The Parts That Are Critical For Safety; Stop The Engine Before Carrying Out Any Maintenance Operation Or Inspection - Komatsu SK818-5 Operation & Maintenance Manual

2.8.7 USE OF THE ENGINE DURING MAINTENANCE

During maintenance operations, run the engine only when indispensable. If it is necessary to have the engine
q
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 this is required.
During maintenance operations with running engine, never disengage the safety locks of the controls from the
q
normal LOCK position.
Service personnel must not move any control lever.
When carrying out maintenance operations, do not touch the moving parts of the machine and avoid wearing lar-
q
ge and loose clothes.
2.8.8 PERIODICAL CHANGE OF THE PARTS THAT ARE CRITICAL FOR
SAFETY
Periodically change the following parts, which are important to prevent fires.
q
Fuel supply system: fuel delivery and return pipes.
Hydraulic system: main delivery pipes of the hydraulic pump.
Even if they seem to be in good conditions, these components must be periodically changed with new ones. In
q
fact, these components tend to deteriorate over time.
If one of these parts is defective, change or repair it even if the recommended change interval has not elapsed
q
yet (see "4.6 PERIODICAL CHANGE OF THE COMPONENTS CONNECTED WITH SAFETY").
2.8.9 STOP THE ENGINE BEFORE CAR-
RYING OUT ANY MAINTENANCE
OPERATION OR INSPECTION
Stop the machine only on firm and level ground and stop the
q
engine before carrying out any maintenance operation or in-
spection.
If the engine must be running during a maintenance opera-
q
tion, shift the safety bars to the LOCK position and carry out
the maintenance operation with the help of another person;
one operator must remain on the machine and the words
and signs to be used must be agreed upon in advance.
The person who carries out the maintenance operations
q
must be very careful not to touch any moving part of the en-
gine.
