If any defects occur on the lift, turn off electricity,
make safe, secure against unauthorised use and
contact your HOFMANN dealer.

neers!
-
Noise during operation

Lack of lubrication, worn lifting spindle, loose V-
belt

Lubricate spindles according to operating label
on lift column. If spindle is defective, replace it.
Tighten V-belt (or replace it).
-
Lift does not operate
Remedy:
Check supply current and motor.
Check main switch, control circuits and thermal
cut-out in motor winding and motor operation.

ting capacity.
Check lubrication between lifting nuts and
spindle.
Check electric lead to motor, check all three
phases.
