Worm gear
In order to guarantee long product lifetime, we recommend to
operate the winch for some time long at the start.
Effect approx. five full drum rotations with approx. 50% of the
nominal load.
Remove the protection plate and distribute the fat with a paint
brush over the worm gear wheel and the shaft.
Make sure that no fat gets on the load pressure brake (A).
Install the protection plate again.
NOTICE!
To ensure correct functioning of the load pressure brake, the winch must be loaded with at least 5 % of the
nominal load.

Wire rope
Wire ropes must be free from corrosion, dirt or damage.
They must be lubricated before commissioning.
No lubrication shortens the lifetime of the wire rope and the maintenance intervals.
WARNING!
It is not allowed to use plastic wire ropes or plastic-coated wire ropes.

Safety check
Before putting into service initially or when putting back into service, it must be checked whether:
All fastening screws (if existent), socket pins, flap socket and safety devices are tightened and secured.

Functional test
The functional test must be effected with the load capacity mentioned on the type plate.
Check the brake when lifting/lowering - it must hold the load safely.
Check the condition of the wire rope and the supporting structures.
Check screw connections.
