POWER BASE SECTION
Adjusting the timing of the anti-pitch effect is •
accomplished by rotating the nut at the end of
the anti-pitch actuation cable at the anti-pitch
housing. The anti-pitch housing is located on
the stainless steel anti-pitch shaft inboard of
the drive motor. (Fig 1.63) (NOTE: The free
threads seen between the nut and the cable
rotary barrel indicate that this anti-pitch is fully
engaged.)
As seen, the barrel end of the cable has
•
a hexagonal shape and while an adjustable
wrench could be set to
fi t this portion of the
cable, a vise-grip type of pliers would be better
suited to this application.
Adjusting the nut clockwise will increase the
•
amount of suspension travel prior to anti-pitch
damping engagement. Adjusting the nut counter
clockwise will reduce the amount of suspension
travel prior to anti-pitch engagement.
After evenly adjusting the timing of the anti-pitch
•
on each side, reinstall the 6mm anti-sway bar
and attaching hardware, then set torque to 6
ft-lbs or 8.13 Newton-meter.
Remove the chair from the pedestal. The
•
procedure is complete.
