Lift synchronization

• Uneven running of the lift is not possible in proper
operation.
• For this, raise the lift to its uppermost end position.
Push the operating lever for 2 more seconds. Dur-
ing this procedure the lift rails are equalised to
each other as hydraulic oil flows to the tank as
an overflow from the command cylinder via the
downstream cylinder to the tank.
• Release the operating lever. The lift rails then
lower some millimetres and thereby block the
overflow opening of the cylinder.
• Both lift rails are now at the same height.
5.4 Lowering the vehicle
• Check that there are no people or objects in the
hazardous area of the lift.
• Lower the vehicle to the desired working height
or to its lowest position; pull the operating lever
slowly v "Lower".
• For heavier vehicles, lift it slightly before lowering
to prevent an "sticking" and any corresponding
jolt during lowering.
• The lowering speed can be varied seamlessly.
• Once the lift is in the lowest position, push the lift-
ing arms to the start position.

Lifting arm start position
Once the lift is in the lowest position, swing out the lifting arms to
the start position.
• Move the vehicle out of the lift.

Behaviour in cases of error

Defective operational readiness of the lift may be
due to a simple error. Check the system for the list-
ed sources of error.
If the error cannot be removed after an inspection
to the named causes, then inform customer service
or your dealer.
Independent repairs to the lift, espe-
cially on the safety devices, as well as
inspections and repairs to electrical
systems are prohibited.
Work on electrical systems may only
be done by electricians.
Problem: The lift cannot be raised
Possible causes:
No power supply pres-
ent
The main switch is not
switched on, or is de-
fective
Operating lever defec-
tive
Defective fuse
Power line interrupted
