D1 SEAT HEIGHT ADJUSTMENT
Pull up the single rod control
lever and hold it while raising
or lowering the seat to change
the seat height. When the
lever is released, the seat
height is locked.
Since an incorrect seat height
contributes to back’s fatigue,
it is recommended that the
angle of knees is slightly less
than 90° and feet are level
with the floor.
