3.9 Maintenance work
3.9.1 Preliminary remarks
Adhere to the specified operating, maintenance and repair meas-
ures.
The machine must only be serviced by qualified personnel author-
ised by the operating company.
Keep unauthorised persons away from the machine.
Perform maintenance work only with the engine shut down.
Make sure that the engine cannot be accidentally started during
maintenance work.
3.9.2 Working on hydraulic lines
Relieve hydraulic pressures before working on hydraulic lines.
Hydraulic oil escaping under pressure can penetrate the skin and
cause severe injury. Immediately call for medical assistance if
injured by hydraulic oil.
Do not step in front of or behind the machine when performing
adjustment work in the hydraulic system.
Do not change the setting of pressure relief valves.
Drain the hydraulic oil at operating temperature – danger of
scalding!
Any hydraulic oil must be collected and disposed of in an environ-
mentally friendly way.
Always collect and dispose of hydraulic oils separately.
Do not start the engine after draining off the hydraulic oil. Once all
work is completed (with the system still depressurized!) check all
connections and fittings for leaks.
Hydraulic hoses must be visually inspected at regular intervals.
Do not mix up hoses by mistake.
Only genuine replacement hydraulic hoses ensure that the correct
hose type (pressure range) is used at the right location.
3.9.3 Working on the engine
Drain the engine oil at operating temperature – danger of scalding!
Wipe off spilled oil, catch running out oil and dispose of environ-
mentally.
When working on the air filter no dirt should fall into the air duct.
Do not work on the hot exhaust - danger of burning!
Store used filters and other oil contaminated materials in a sepa-
rate, specially marked container and dispose of environmentally.
