Use common multi-purpose oil or grease for lubricating.
Do not use any lubricants which contain molybdenum
disulphide (MoS
2
) or PTFE!
C) Motor and motor brake
The electro-motor of the winch is maintenance-free.
Clean the motor cover if it is extremely dirty to make sure that the motor
is supplied with enough air.
The motor brake is maintenance-free; it must, however, be kept free of
oil and grease!
Only clean in the case of exceptional operation conditions and in the case
of strong dirt accumulation.
6.1 Maintenance and servicing
A) Rope drive and gearbox
Rope drive and gearbox are almost maintenance-free.
Lubricating the ropes on a regular basis provides the rope drive with
sufficient lubrication.
The service life of the rope drive is considerably increased
by lubrication. The traction of the rope is not affected by
proper lubrication.
B) Wire ropes
• Wire ropes must always be slightly lubricated. Ensure that they are
clean, i.e. do not deposit them on dusty ground or in dirty surroundings.
• Never use wire ropes to fix a load.
• Always wind and unwind the wire ropes properly on/from the reels.
• Never pull wire ropes over edges.
