
Fuses: check the values.
Heat sink and fan: clean.
Height measuring system for the main lift: check the function and condition of the
measuring tape and check that the component is securely mounted.
Height measuring system for the auxiliary lift: check the condition of the magnetic
strip and protective tape and check that the components are securely mounted.
Displacement transducer for the load wheel: check for contamination, check the
condition and check that the component is securely mounted.
Displacement transducer for the load wheel: check the O-rings for contamination,
check the condition and check for wear. Replace if necessary.
Hydraulics
Check the oil level in the hydraulic system To do this, fully lower the load support.
The oil level must be between the minimum and maximum marking. The markings
on the hydraulic oil tank become visible once the control compartment hood is re-
moved.
Hydraulic system: check for leak tightness.
Hydraulic oil filter of the hydraulic oil tank: replace.
Air filter of the hydraulic oil tank: replace.
Pump motor: check for operating noise.
Hose lines: check the pre-load.
Load lift system
Stops and end lift cut-out: check the condition and function.
Lift cylinder: check the mounting.
Lift cylinder: visually check bearing points and their weld seams.
Main lift load chains: check the condition, lubrication and tension and check for
wear, elongation and damage.
Auxiliary lift load chains: check the condition, lubrication and tension and check for
wear, elongation and damage.
Main lift load chains: determine wear (maximum permissible wear is 2%)
Auxiliary lift load chains: determine wear (maximum permissible wear is 3%)
Load chains: lubricate with chain spray.
Chain rollers: check for ease of movement.
Mast channels: check the surfaces for wear.
Mast channels: lubricate the surfaces with grease.
