This product is a precision made hydraulic machine. Therefore great care and
cleanliness should be taken when handling any of the hydraulic components. Dirt is
the worst enemy in hydraulic systems.
Handle the parts carefully and remember to cover any cleaned and dried parts with
clean lint-free cloth. Do not use anything other than purpose designed materials for
cleaning hydraulic parts. Never use water, paint thinners or carbon tetrachloride.
Components, gaskets and seals in the hydraulic system should be oiled with clean
hydraulic oil before assembly.
Note: The time intervals given refer to the carrier hours while the attachment is
installed.
Check that the grease cartridge is not empty. Replace if necessary.
Check that the tool has received sufficient grease.
Grease manually if the automatic greasing device is not in use. See “Manual
greasing” on page 44.
Observe hydraulic oil temperature, all lines and connections as well as impact
efficiency and evenness of operation.
Tighten loose connections.
Remove the tool retaining pin and the tool and check their condition. Grind the
burrs away if necessary. See “Changing the tool” on page 55.
Check that the tool has received sufficient greasing. Grease more frequently, if
necessary.
