GRAHL DUO-BACK 11 & 12 - INSTRUCTIONS
1. SEAT HEIGHT
To raise the chair height, lift this
lever on the right-hand side (whilst
facing away from the chair) whilst
unseated. To lower the chair height,
lift this lever whilst seated.
4. SEAT TILT (IF FITTED)
Push the lever on the right-hand side
(whilst seated) pull down and
backwards to release the independent
seat tilt. Adjust the seat in angle back
or forth and lock in the desired
position by pushing this lever down
and forwards.
2. ASYNCHRO ADJUSTMENT
On the left hand-side (whilst seated)
pulling up this lever the chair
mechanism will be in free float. To
lock asynchronous mechanisms
simply find a position you find
comfortable and lower the lever to
lock it off.
5. SLIDING SEAT
Depress this button and slide the seat
back and forth to adjust the seat to
your leg length. Releasing the button
will lock the seat in place
3. WEIGHT TENSION CONTROL
First pull this out sideways to the

clockwise you will increase the level
of resistance to the asynchro action
of the chair and by rotating it
anticlockwise, the resistance is
reduced.
6. BACK HEIGHT ADJUSTMENT
Turn the bottom wheel in an
anticlockwise direction to loosen the
back rest; with your free hand raise or
lower the back rest to the desired
height and lock it in place by turning
this wheel in a clockwise direction.
