Danger of overturning when moving into the shutdown ranges
Avoid lowering the boom. If you cannot avoid lowering, try to set down the

Lifting capacity table .
Before slewing, always check whether this is permissible in the current rig-
ging mode;

Risk of accidents when operating the slewing gear
Set down in the crane cab to operate the slewing gear. This prevents you
being pushed off the carrier or being crushed by the carrier as a result of
slewing.
Lay the connecting cable of the hand-held control so that it will not catch
on anything.
