Description of Required Inspection and Maintenance
5.1 Hydraulic System
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 unin-
tended 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.
5.2 Adjustment of the Lifting Chain
Adjust the chain length by tightening the tension nut
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%
5.3 Electric System
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.
Maintenance works may only be executed by authorised and competent personnel.
5.3.1 Fuses
Fuses are located on the electrical installation in the battery box. Before replacing a fuse check the
system for reasons why the fuse failed.
Only use the recommended fuse size. Replace failed fuses with a new fuse of the same current strength.
In no case it is allowed to mount repaired fuses or several fuses together.

6.1 Substituting the battery
To avoid short circuits, batteries with unprotected terminals or connectors should be covered with a
rubber mat. When replacing batteries with lifting tackle the crane should execute a vertical movement so
that the battery tray is not compressed. Hooks are to be attached in such a way that they cannot fall on
the battery cells when the lifting tackle is not tensioned. Where the battery replacement is made with a
battery trolley it must be ensured that the vehicle and trolley are secured against involuntary movement
while the battery is being shifted.
Remove the battery from its retainers; Remove the cables from the battery terminals; Slide out the
battery; Mount the battery following the above instructions in reserve order, fixing in place and
connecting it correctly.
Before assembly check the battery for correct mechanical condition.
Fix the pole terminals safely to the respective end poles + and - of the battery. This is a permanent
connection and shall not be used for continuous changes.
