NOTE! Adjustment of hydraulic cylinders is to be carried out without pressure in the system.

WARNING! Nobody is allowed to be under the boom whilst adjustment is carried out.

Glide shoes - yaw damping

If slack occurs (backwards and forwards movements of the boom)
adjustment of yaw damping is needed. This is done by slightly
tightening the bolts (A). Be carefull not to overtighten or squeeze the
rubber bushings (B). Only tighten until there are no more play!

Trapeze locking device

The trapeze helps the boom to stay horizontal when unfolded and it protects the boom against vibrations and impacts. In
order to lock the boom during folding, the chains must be tight. If this is not the case even when the cylinder is fully
retracted, the chains must be strained.
