Checking

• Raise the hook block until there are approx. 10 turn on the hoist drum.

switches off properly.
The lowering limit switch must switch off the hoist while 3 rope turns are

The lowering limit switch must always be reset after repair work on the
hoist and after rope replacement. A faulty lowering limit switch must
always be replaced!
