Before the emergency lowering can be done, the safety
catches (j) must be manually retracted. When the safety
latches are snapped, the lift must be moved out of the lat-
ches or lifted with a suitable device to release the latches.
Then the safety ratchet can be tied back via a cable tie (i)
or a wire (see figure 012). This has to be done on all four
columns of the lift.
During the emergency discharge ensure the-
!
re are no people under the lift!

To lower the lift the control valve MV2 (m) on the aggre-
gate has to be opened.
Therefore the unit cover has to be removed. The control
valve MV2 is the left one of the two valves. Again, first the
black cap has to be removed and then the screw-on cap
with the Allen screw (f) is fastened.
By tightening the Allen screw the valve MV2 is opening
and the lift begins to lower. The lower-ing speed can be
controlled by adjusting the Allen screw.
In case of danger stop the lowering operation by closing
the valve MV2.

The lowering process must always
be observed!
The safety latches must be relea-

7 Maintenance and care of the
system
Before maintenance, do all prepa-
ration work so there is no danger
to life or limb or object damage du-
ring maintenance and repair work.
To guarantee the utmost availability and to ensure that the
lift remains functional, maintenance work contracts are
organised between our clients and their local retailers.
A service must be performed at regular intervals of
3 months through the operator in accordance with follow-
012
ing service manual. If the lift is in continuous operation
or in a dirty environment, the maintenance rate must be
increased.
During daily operation the lift must be closely observed
to ensure that it is functioning correctly. In the case of
malfunction or leakage the technical service must be in-
formed.
7.1 System maintenance plan
Before beginning service, discon-
nect from power. The system is to
be secured against unintentional
lowering and unauthorized access.
