Setting the height adjustment for the spring arm /
changing the left/right sled guide
The element for mounting the spring arm can be mounted for left or right-bearing operators. To switch the position,
open both smaller clamping levers (Fig. 57). Pull the mount out of the guide completely and turn it 180 degrees
(Fig. 58 & 59).
Re-attach the sled to the guide and adjust to the desired height by closing the clamping lever. Your preference for the
post guide is crucial for the carrying position. Just try both variants.

Setting the adjustment angle
The assembly unit also has a stepless angle adjustment option for the spring arm with -20 to +20 degrees of travel. This
adjustment makes system balance possible depending on your natural body posture and shape or the task.
Generally, an angle adjustment of up to 10-15 degrees to the rear is desired, i.e. raising the mounted spring arm. If the
angle points too far forward, the system moves strongly away from the body and too much effort is expended to
counteract the movement. If the angle points too far back, the system moves toward the body appropriately.
The goal is to achieve a neutral angle position in which a natural, straight posture can be maintained and the system can
be guided "near the body" without exertion. Freehand balance exercises show you the correction requirement.
Open the large clamping lever (Fig. 61). You can move the lever by pulling it and re-
engaging it in position.
