Vane motor and transmission parts inspection
We recommend to perform the first inspection after an operating time of 12 000 times 1 meter lifts. Follow
the instructions in the Maintenance section in the Service manual.
Brake adjustment
The disc brake of the air hoist is correctly adjusted upon delivery. If adjustment is necessary, use the fol-
lowing procedure:
1.
Unhook the load.
2.
Unscrew the setting screw approximately 360 degrees.
3.
Connect the hoist to the air supply and run it slowly in the lifting direction, without any load.
4.
Tighten the setting screw until the hoist stops or clearly slows down.
5.
Unscrew the setting screw approximately 45 degrees until the hoist rotates easily again.
If the brake cannot be adjusted in accordance with these directions, the brake shoes and brake
disc should be cleaned with a grease solvent, see section Service.
6.
Before using the hoist again, load and lift the intended load – or rated load if possible – approxi-
mately 15-30 cm (6-12 inches) and check that the brake holds the load in position. Adjust if neces-
sary.
Make sure that the brake is not adjusted too hard by driving the hoist unloaded at 1 bar air pressure.
The hoist should start easily without influence from the brake.
