6. Troubleshooting
If the lift does not work properly, the reason for this might be quite simple. Please check
the lift for the potential reasons mentioned on the following pages. If the cause of
trouble cannot be found, please call the technical service of the dealer.
A simple fault delimitation can be carried out at the LED-display of the operating unit.
(see the step 5.5 LED-Display visibly at the operating unit).
Repairs at the security devices of the lift as well as repairs and examinations
of the electrical fittings are forbidden.
Problem: The lift does not lifting and not lowering!
possible causes: remedying:
the main switch is not switched on switch it on
the main switch is faulty replace it
the fuse is faulty replace it
the feed line is cut replace it
the motor is overheated let it cool down
the plug is not plugged in plug in
the lift is not in the regulation range equalize manually
Problem: The lift does not lifting!
possible causes: remedying:
the lift is running at 2 phases make sure 3 phases by customer
V-belt is torn/slack check it / replace it
the lifting nut is broken call the service partner
top limit is active lower the lift
Problem: The lift does not lowering!
possible causes: remedying:
the bottom limit switch is active raise the lift
lift is driven on a obstacle equalise manually
6.1 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.
