Adjusting the backrest upholstery
Adjust the tension of the backrest´s top-belt
- Tear both velcroed halves of the top belt apart (Fig.4.25)
- Tension the top-belt or remove tension. Once the desired
strain is set, velcroe both halves back together
- In case of the top-belt laterally protruding over the push-
handles, the belt can be cut to size with a pair of scissors.
Cut the belt between the grey stitchings. The stitching will
prevent the belt from fraying, Melt the cutting edge of the
belt for additional fray-protection. (Fig.4.26)

Do not use the velcro-laces around the push-handles to set the
strain of the belt (Fig.4.27). Those must be velcroed to the top-
belt using their full length.
