Check that the auxiliary hoist is functioning properly

Check the slewing direction before laying on the hoist rope.
Risk of accidents due to incorrect slewing direction
Check after each installation that the slewing direction is correct.
This prevents accidents caused by the hoist rope winding up unexpectedly
when it is applied.

Ask someone to observe the slewing direction for you, or stand next to the
auxiliary hoist and use the hand-held control.
