9.0 DEALER SERVICE AND ADJUSTMENT
J. ADJUSTING TILT ANGLE
(Seat to Floor angle)
Tilt angle (seat-to-fl oor angle) can be adjusted to
10°, 20°, or 30°. (Fig 9.46, on next page)
Removing Tilt Pin
1.
Remove legrests. Flip chair upside down
(Fig. 9.37) and remove wheels.
2.
Familiarize yourself with the tilt adjustment
components shown in Fig 9.38 (outer bolt
not shown).
Note: actual large spacer may look diff erent
than as pictured.
3.
Using a 5mm allen wrench for tilt pin bolts
and 4mm allen wrench to keep tilt pin from
spinning, remove inner bolts and outer bolts
on both sides of chair. (Fig 9.39 & Fig 9.40)
4.
Starting on one side of the chair, remove tilt
link from tilt pin. If the tilt link doesn’t easily
detach from the tilt pin, use a 4mm allen in
tilt pin hole and rotate tilt pin back and forth
until tilt link detaches (tilt spring releases tilt
link). (Fig 9.41)
5.
On the same side of the chair, remove the
spring and small spacer (can keep large
spacer attached to tilt pin if desired). Next,
remove the tilt pin from the lower link and
then from the rear frame, ensuring you catch
the small spacer located between these two
frame components. If the tilt pin doesn’t
easily remove, use a mallet and 8mm Allen to
lightly tap the tilt pin free. (Fig 9.42)
6.
Repeat steps 4 and 5 for the opposite side
of the chair.
