(extension tube 3).
• Adjust required height of the towbar.
• Tighten locking nut (2) by hand first.
• Secondly tighten locking nut (2) with a tightening 
torque corresponding to table. With an extension 
tube (3) (“A” corresponding to table) and 
handforce (“B” corresponding to table) easy 
tightening is possible.

levelled ground and in coupled condition.
• When readjusting, make sure that the front point 
of the towbar is horizontal to the coupling point.
• Before starting a trip, make sure that the 
adjustment shaft is secure, so that the stability and 
safety is guaranteed while driving. If necessary 
tighten the locking nut (2) corresponding to table.
LIFTING INSTRUCTIONS
When lifting the compressor, the hoist has to be
placed in such a way that the compressor, which must
be placed level, will be lifted vertically. Keep lifting
acceleration and retardation within safe limits.
Preferably use the lifting eye (1) after opening the
small door (2).
Before towing the compressor, make
sure that the joints of the towbar are
secured with maximum strength without
damaging the towbar. Be sure that there
is no clearance between the teeth of the
joints.
