Care and
maintenance
Observe the care and maintenance intervals
Observe the periods specified in the operator’s manual for recurrent
checks and inspections. If these periods are not observed, damage to
the machine and accidents may be caused as a result.
Use original parts
Many components have special properties that are essential for the
stability and correct operation of the machine. Only spare parts and
accessories supplied by the manufacturer have been tested and
approved. Other products may adversely affect the correct operation
of the machine and safety. Using non-OEM replacement parts renders
the manufacturer's guarantee null and void and frees the manufac-
turer from all liability.
When performing care and maintenance work:
•
Switch off the PTO shaft drive.
•
Depressurise the hydraulic system.
•
Whenever possible, uncouple the tractor.
•
Place all controls in neutral or park.
•
Set tractor parking brake.
•
Shut off the engine, set the parking brake, remove the ignition key
and secure the tractor against rolling away.
•
Ensure the machine is standing on firm, secure and level ground,
and provide additional support, if necessary.
•
Secure the machine against rolling away (use wheel chocks).
Only if these regulations are observed can safe working be ensured
during care and maintenance work.
Turn off the electrical supply
Prior to carrying out work on the electrical system, disconnect the
system from the power supply. Systems being supplied with electrical
power can cause damage to equipment and injury to persons.
Caution when cleaning with a high-pressure cleaner
Exercise caution when cleaning with a high-pressure cleaner.
Bearings, seals and pipe unions are not waterproof. In order to
prevent damage to the machine, the bearings, seals and pipe unions
must not be exposed to direct contact with the high pressure water jet.
No aggressive washing additives
Do not use any aggressive washing additives for cleaning. Uncoated
metal surfaces can be damaged.
Before carrying out welding work
Disconnect all electrical connections from the tractor when carrying
out welding on the hitched machine. Damage may otherwise be
caused to the electrical system.
Retighten all nuts, bolts and screws
All screwed/bolted connections that are loosened during maintenance
and repair operations must be retightened. Serious injury and damage
to property can be caused by loose pin and screw connections.
See »Tightening bolts«, page 92 for proper torque values.
