Battery cables, battery connectors, battery male connectors: check the condition
and check for secure attachment.
Battery cable: visually check the insulation.
Battery: measure the battery voltage under load
Battery: measure the tray for short circuits.
Battery: check the electrolyte level.
Drive and pump controller: check the driving, acceleration, braking and reversing
functions.
Plugs and connections: check that they are securely attached.
Openly routed cable
s: visually check the insulation.
Contactor contact
s: check the condition and check for erosion. Replace if necessary.
Fuses: visually check the condition.
Fuses: check the values.
Heat sink and fan: clean.
Hydraulics
Hydraulic system: check the oil level 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 removed.
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
Sto
ps and limit stop: check the condition and function.
Lift cylinder: check the mounting.
Lift cylinder: visually check bearing points and their welded seams.
Main lift load chains: check the condition, lubrication and voltage and check for wear,
elongation and damage.
Auxiliary lift load chains: check the condition, lubrication and voltage 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%)
