assistance if clip is missing or damaged. Clean polyurethane
seat and backrest with soap and water. To repair cuts, apply
a few drops of quick drying glue in the cut and press the

SEAT HEIGHT ADJUSTMENT
Sit centered in seat. Locate handle (Key
No. 5) under seat and pull up. Ease weight
up or down until you have reached the
height you want, and release lever. The
proper height is determined by a combination
of height of work surface, task performed and
body size. Stool should be high enough so
arms form 90° angle at the elbow or slightly
greater. This allows better circulation in
shoulders and neck area and reduces
fatigue in forearms and hands. Feet should
be flat on ground or footrest. Maintain a 90°
angle at bend of knees.
BACKREST DEPTH ADJUSTMENT
Adjustment knob (key No. 11) is located
under seat just behind pneumatic lift.
Loosen knob to slide backrest into position.
Allow surface of backrest to help support
upper body weight by positioning backrest
in curve of your spine. This will reduce
pressure on the spinal discs, especially in
lumbar area. Backrest should tilt freely to
enable support in various positions.
Tighten knob.
BACKREST HEIGHT ADJUSTMENT
Loosen knob (Key No. 14) behind backrest.
Adjust backrest until curve fits into small of
your back. This will reduce pressure on the
spinal discs, especially in lumbar area.
Retighten knob.
