Gridded backrest
The gridded backrest's positioning guide allows you to quickly and efficiently
measure the width of an individual's shoulders and chest, as well as determine
the correct position of lateral supports.
Adjusting the lateral supports
Lateral supports are positionned by default in the outer adjustment slots. Before
beginning adjustments, determine if the lateral supports should be placed in the
inner adjustment slots. If so, follow these steps :
1. Unscrew both handles A completely.
2. Move both lateral supports to the inner adjustments slots.
3. Refasten handles A.
Once the lateral supports are positionned in the correct adjustment slots, you
may begin adjusting the lateral supports:
1. Loosen both handles A.
2. Adjust the height of the lateral supports by moving the laterals upwards or
downwards along the adjustment slots.
3. Adjust the distance between both lateral supports.
4. Firmly tighten handles A when lateral supports are correctly positionned.
5. Note the position of the laterals on the gridded backrest.
