Fault Possible cause Remedy
Lifting not possible Overload protection has Lower hook briefly, limit load to permissible
caused deactivation load carrying capacity, then lift again. If loads
within the load carrying capacity range are
not lifted, the overload protection must be
adjusted.
Set the air pressure correctly. Air pressures
which are too high can cause deactivation
within the load carrying capacity range.
Air pressure too low Increase air pressure to the required value
EMERGENCY STOP button Release the EMERGENCY STOP button once the
is pressed danger has been rectified
Hand control is faulty Have hand control repaired
Only very slow lifting possible Brake does not release fully Set air pressure to the relevant value, check
seal of brake piston and change seal if

necessary
Lifting or lowering speed declines Brake piston setting too tight Correct adjustment of brake piston. At high
with high lifting heights or the ambient temperatures, perform adjustment
motor comes to a standstill with the device warmed up accordingly.
