A damaged or non-existent buffer can lead to a
fracture of the chain if the upper or lower hook
end position is met.

Have the product repaired (replace buffer)
The buffer of the lifting limiter (optional) and low-
ering limiter must be visually inspected daily. If the
buffers have cracks, permanent deformations or
other damage, they must be replaced.
8.11. Check lifting limiter
WARNING
Danger from chain fracture
If the buffers are damaged, inadmissibly high
loads may act on the chain upon actuation of the
lifting limiter. The chain may break.

1. Move the unloaded load hook until just short
of the upper end position.
2. Stop immediately before reaching the end po-
sition and then carefully (by repeatedly press-
ing the control element) move to the end posi-
tion.
3. The movement of the chain must be stopped
due to deformation of the buffer. Due to the
overload protection, the lifting movement is
additionally limited by shutting off the motor.
4. Following successful testing, the buffer must
be unloaded.
