For Rhythm, each rear suspension element controls
the pitch damper mechanism on that side of the chair.
Timing of the initiation of the anti-pitch function on the
Rhythm can be accomplished by the following method.
Place the chair on a pedestal so that the drive •
wheels are suspended off of the riding or work
surface.
To allow a clearer indication of anti-pitch function, •
move to the front of the chair and remove the
6mm hardware that secures the anti-sway bar
end links to the motor mounts (Fig. 1.60).
Lift the rear caster so that the black rubber pad •
on the front of the rear shock mount is against
the chassis tube (Fig 1.61).
The motor on that side of the chair should move •
freely on its pivot and the anti-pitch tube.
Slowly lower the rear suspension so that the •
black rubber pad on the front of the rear shock
mount separates from the chassis tube (Fig
1.62).
After the rubber pad separates from the chassis •
tube the effort required to move the motor about
its pivot should increase substantially. This is
the pitch damper increasing the suspension
damping level.
The increase in motor movement effort should •
take affect before the rubber pad has separated
from chassis tube by more than 1/8”. This
constitutes pitch damper “timing”
