BACKREST ANGLE – OPTION Z-C3-A
The backrest angle adjustment is done with a 4-position telescopic support
located under the seat.
1. Lay the chair on its side. Unlock
the spring pull by turning the knob
counterclockwise until it won’t turn
any further, then pull while holding
the backrest with one hand.
The backrest angle adjustment can vary from 93 to 112 degrees to
accommodate the shape of a user’s back. Adjust the backrest tilt for a
comfortable position with the lower back supported as well as the head
so that there is a good field of vision in front of you.
3. IMPORTANT: lock the spring pull by
firmly turning the knob clockwise.
WARNING: THE CHAIR MUST BE UNOCCUPIED WHEN MAKING THIS
ADJUSTMENT.
2. Adjust the backrest angle as
desired then release the pull while
ensuring that it slides into a hole.
