5 Description of Required Inspection and Maintenance
Hydraulic System
5.1
The hydraulic system consists of the hydraulic aggregate with mounted-on speed-adjustable lowering
valve and safety valve, as well as lifting cylinder with incorporated lowering brake valve.
The hydraulic system requires almost no maintenance apart from the recommended tests and the
required oil change.
Prior to maintenance or repair relieve the pressure in the hydraulic system. Lower the fork completely and
remove the load.
If repair is unavoidable on the extended lifting structure, secure all parts (fork, mast, cylinder)
against unintended lowering.
Do not run the hydraulic pump without oil!
Replace the pressure hoses in case of damage or on demand, but at least after 6 years.
For oil changing suck the oil out of the oil tank.
Ventilate the hydraulic system after oil change or on demand.
Ventilation may only be effected in unloaded state.
Adjustment of the Lifting Chain
5.2
Adjust the chain length by tightening the tension nut
and
so that the load
chain is tightened when the fork is completely lowered.
At regular intervals, check the lifting chains for fractures, scores and marks of wear.
The permissible elongation must not exceed 3%.
Replace damaged chains or those elongated by more than 3%
Electro-magnetic Spring Brake
5.3
Works on the brake may only be executed by authorised and competent personnel.
The electromagnetic brake works directly on the drive motor.
The brakes are virtually maintenance-free.
However, we recommend to check the ventilation gap at regular intervals depending on
type of application (every 2000 operating hours).
5.3.1 Brake EGV PSL 10..
The electromagnetic brake works directly on the drive motor. The braking
force can be set by adjusting the screws (A).The gap (0.4 mm) between
disc (C) and brake lining is adjusted by means of the screws (B).
5.3.2 Brake EGV PSL 12..
The electromagnetic brake works directly on the drive motor. The braking force
can be adjusted by rotating the slotted ring. Rotate the ring clockwise to
increase the brake force.
Electric System
5.4
During all works on the electric system, pull the battery plug out of the feeding socket.
Due to danger of short circuit , no metallic objects must be laid on the battery.
5.4.1 Fuses
Fuses are located on the electrical installation in the battery box. To change a fuse remove the battery
box cover. Replace failed fuses with a new fuse of the same current strength. Before replacing a fuse
check the system for reasons why the fuse failed.
