Follow the maintenance intervals by checking the hour
meter every day. Before starting maintenance, park the
machine on flat, firm ground, away from any obstacles,
with the attachments on the ground. Keep all unautho-
rized personnel clear of the area. Unless otherwise spec-
ified, all maintenance operations should be carried out
with:
• the engine stopped
• the machine parked on a firm, level surface
• the parking brake engaged
• the key removed from the key switch
• a "DO NOT OPERATE" tag on the key switch
• wheel chocks blocking the tracks
• all circuits cooled down prior to starting work
• all hydraulic pressure released
• any accumulator pressure released for the appropriate
circuit
Clean the grease fittings before lubrication. Clean around
plugs and filler holes before adding fluid. No dust or dirt
must enter the components or the circuits. Wear suitable
clothing, and use the necessary safety equipment.
Place a Do Not Operate tag on the instrument panel or
key switch when performing service work on the machine.
Turn off engine, and remove the key before leaving oper-
ator's compartment.
Any modification to this machine without prior authoriza-
tion could cause serious injury. Do not make any mod-
ifications without authorization. Consult your authorized
dealer.
The service intervals in this chapter refer to normal op-
erating conditions. During the first operation period of a
new machine or rebuilt component and under particularly
severe conditions, the service intervals should be carried
out more frequently.
Take particular care to replace all filters regularly. Clean
filters mean longer engine running life.
Oils and fluids must be disposed of properly.
