7.1 Emergency lowering in case of power failure
In case of power failure the lift can not lowered with the motors. In this case there is the
possibility to lower the lift manually. Draw the main plug or switch off and lock the
main switch and remove the cover of the v-belt pulleys. For this the lift must be turned
down to lowest position at the nut on the top end of the spindle. If the lift is in the
lowest position removes the vehicle.
The emergency lowering must only carried out by persons which are
instructed to using the lift. Please refer to the regulation “Lowering the
vehicle”.
Procedure – emergency lowering
• loose the main plug; switch off the main switch and lock it.
• remove the cover of the v-belt pulleys.
• lower the lift: turn the nuts (every side) alternately 5 cm until the lift has reached
lowest position.
• after the emergency lowering: Do not work with the lift until the faulty parts are
exchanged.
7.2 Driving onto an obstacle
If the lifting arm or the lifting carriage is driven on a obstacle, the motor from this side
locked. The lift switched off if the lifting carriage are not more in the regulation range
(approx. 25 – 30 mm) (since 9/99 64 mm).
An additional protection is a temperature control in the motor. Which interrupt the
electrical circuit when it is overloaded. You can not work with the lift. Cool down
approx. 5 – 10 min. dependently on the outside temperature.
After the locking of the motor check the V-belt if necessary replace it. Call the service-
partner.
7.3 Function of safety device
The lift is equipped with a safety switching, which controls the wear of the main nut.
If the lifting nut is broken, a safety nut which is conducted loose in the spindle, carries
the load. After a break of the nut, the lift can only once being lowered in the lowest
position. If the lift has reached the lowest position it is not possible to raise the lift.
The lifting carriage of the broken side gets mechanically locked. During the lifting the
other side is driving out of the regulation range and switched off the lift. You can not
work with the lift anymore. Call the service-partner.
If the safety device is active call the service partner!
Switch off the main switch at all repairs and disturbances!
The electrical system may only be opened by trained persons!
