6.2 Emergency discharge
If there is a power outage or a defective motor the lift can
no longer be lowered. There is the option of placing the
lift into the lowest position.
An emergency discharge can only
be done by personnel who are
trained to operate the lift. Follow
the conditions to "Lower".
Emergency discharge procedure
• Disconnect from power or switch off the main switch
and secure against switch on.
• Remove both v-belt covers.
• Carefully turn the hexagonal nut at the upper end of
the lift spindle anti-clockwise using a suitable tool. This
procedure is to be done alternately (5 cm) on both lift
spindles, until the vehicle is placed on the wheels and
the lifting arm can be positioned in the starting position.
If there is a defect stop the lift and secure against unau-
thorised use. Inform customer services.
6.3 Triggering the safety mechanism
The lift is provided with a safety mechanism that activates
when the lift nut breaks. After a break of the lift nut, the
safety nut moving with the spindle takes up the slack on
the spindle and assumes the load. After a lift nut break the
lift can be lowered once. After reaching the lowest posi-
tion, the lift can no longer be lifted, this means the lift is
mechanically interlocked on the defective side by a safety latch. If an attempt is made to raise the lift, the lifting rails
move out of the control range and the lift switches off. The
lift is then to be secured against unauthorised use (e.g.
switch off and lock the main switch) until the lift has been
properly repaired. (this also includes the exchange of the
lift and safety nuts).
As the triggering of the safety
mechanism is a result of a lift
defect, customer services must be
informed.
The main switch must be switched off, or the
!
lift power disconnected and secured against
switch on for all errors and repairs.
The electrical controls may only be
opened by a trained electrician.
6.4 Manual equalization of the lifting rails
To ensure synchronous running of both lifting rails, both
are connected to a position measuring system. If one lift-
ing rail moves forwards approx. 18 mm, this is detected

by the electronic controls. Following that, the more ad-
vanced lifting rail is stopped until both lifting rails are at
the same height again, only then is the motor restarted.
However if the lift moves out of a switch off or control win-
dow more than 64 mm, this is detected by the electronic
controls and the lift switches off.
To enter the normal control range of 18 mm again, the lift
must be manually equalised.
Remove the upper column of a cover, turn the nut on the
upper end of the spindle until both sides are at the same
height again.
6.5 Readjustment of the "Up and Down
Off"
The potentiometers are to be set and checked in the fac-
tory for proper function. For safety reasons, settings on
the potentiometers can only be done by factory trained
specialists (competent personnel).
A check of the settings must be done during
!
assembly.
• If maintenance of repair work is done on the operating
element, it must be disconnected from power first. (e.g.
pull out the power plug)

The maximum height from the upper edge of the base
plate to the upper edge of the lift rails, during the change
of the "bottom off" via the potentiometer on the controls,
must not exceed 695 mm.
