Removing the
lifting limit switch
This section describes complete removal.
If the hook block is to be attached to the bumper at a later point, you will

halves of the weight apart.

rope line.
• Pull the safety pin (1) out, fold the two
halves of the weight back together and let
the safety pin engage.
• Remove the lifting limit switch weight (2).
• Remove the lifting limit switch weight on the
other side too, if necessary.

• Pull the plug from the socket (1).
• Insert the bridging plug (2) into the socket
(1).
• Remove the lifting limit switch (4) from the
clamp (3).
