6.1 Moving onto an obstacle
If the lift moves onto an obstacle during lowering, or re-
mains stuck with the safety catches in the catch bar, a ca-
ble loosens. A safety switch (5) located below the drive-in
rail is acti-vated and the lift switches off. In this case, move
the lift upwards by pushing the "Bridge" and the "LIFT"
buttons
on the operating panel until the obstacle can be
o
removed or the cable is tensioned again.
Afterwards the lift is in a normal work condition and can
continue to be operated as de-scribed in the operating
manual.
6.2 Emergency Lowering
In case of power failure or defect of the electromagnet,
the control valve (m) can not be opened. Therefore, the lift
can not be lowered. In this case, it is possible to open the
control valve (m) manually and bring the lift in the lowest
position so that the vehicle can be driven from the lift.
An emergency lowering is an
engagement into the system con-
trols and may only be done by
experienced specialists. The emer-
gency lowering 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 is not permitted
and must immediately taken care of. This is ab-
solutely necessary especially before an emergen-
cy lowering.
i
If there is a power failure an emergency lowering can
only be done if the safety ratchets (j) are not engaged.
For this reason wait until the power failure is over.
If there is a defective valve, a latched in lift can be
slightly lifted by pushing the "LIFT" button
catches (j) can be manually retracted.
People may not stand in the hazardous area around the
lift.
The safety ratchets must be capable of being manually
retracted in order to fasten them using a suitable object
(e.g. wire) against latching in.
In order to execute the emergency lowering the following
tools are required:
• 1 x screw-on cap with Allen screw (f)
• 2 x screw-on cap with wing bolt (g)
• 1 x 3 Allen key (h)
• 4 x cable ties/wire (i)
