• The lift must be raised and lowered several times with-
out a vehicle while observing the entire lifting and low-
ering process.
• The covers must be replaced.

6.2 Emergency discharge of the lift

An emergency discharge is an
access into the lift controls and
may only be done by experienced
specialists.
The emergency discharge must be
done in the following described
sequence, otherwise it can lead to
damage and hazard to life and limb.
Any kind of external leakage
(defective hydraulic pipe) is not
permitted and must immediately
taken care of. This is absolutely
necessary especially before an
emergency discharge.
An emergency discharge can only
be done by personnel who are
trained to operate the lift.
Reason which make an emergency discharge necessary
are for example, electrical blackout, for errors in the low-
ering valves, etc.
For a power outage or defective valves, there is the option
of lowering the lift to the lowest position with some man-
ual movements, so the vehicle can be moved from the lift.
Do an emergency discharge
• Switch off the main switch and secure against restart
(shut down).
• Loosen and remove all unit covers.
• For safety reasons, block off the endangered area and
the lift leaving ample room.
• Loosen and remove 2 counter nuts (spanner width 41)
at the upper end of the lift rails in the direction of the
arrow. This procedure must be done on all lift rails.

• The piston rods can jam in the upper bore of the lift rail
when they are limited by any contamination deposits.
To loosen these connections, we recommend a commer-
cially available solvent and simultaneous lubricant (e.g.
WD40). Spray this penetrating spray generously be-
tween the thread and bore. The treatment time depends
on the degree of contamination.

• The cover of the mini-measurement connection and the
tank cover must be loosened. Unscrew the correspond-
ing mini-measurement hydraulic line approx. 500 mm
long (available from your dealer), connect it to Me 3
and insert the other end into the tank.
Figure 8
• Screw on the long threaded sleeve (available from
your dealer) and tighten clockwise using a suitable tool
(spanner width 24) Lower the lift rails approx. 5-10 cm.
Repeat the process on the next lift rails etc. The lift rails
may only be lowered in steps of 5-10 cm until the entire
lift has reached the lowest position.
