O. REAR AXLE
1. Center of Gravity Adjustment
The more you move your rear wheels forward, the more likely your chair will tip
over backwards. Always make adjustments in small increments, and check the sta-
bility of your chair with a spotter to prevent a tip-over. We recommend that you
use anti-tip tubes until you adapt to the change and are sure you are not at risk to
tip over. Refer to additional Warnings in Section VI "Falls and Tip Over".
NOTE– Changes to the center of gravity may affect the rear seat height, toe-in/toe-out of the rear wheels and
the squareness of the casters. If you change your center of gravity position, re-adjust all of these settings
if necessary.
NOTE– Adjusting your chair's center of gravity will require re-adjusting the location of the wheel locks
(if provided). See Section ""Q" for instructions on adjusting the wheel locks.
The GTX Swing Away and GTX Fixed Front has two methods of adjusting Center of Gravity (CG).
2. Primary Center of Gravity Adjustment
a. GTX Swing Away & Fixed Front
Place the entire wheelchair on a flat horizontal table or ground surface. Remove both rear wheels
from wheelchair. Remove the four screws, washers and nuts (A) (2 per side). Thus allowing the
axle sleeve clamp to be repositioned in desired location. Axle sleeve clamp can also be reversed to
achieve greater range of adjustment
side clamp with the right side to eliminate the need to remove and flip axle sleeves. Reinsert four
screws (A) (2 per side), washers and nuts to secure sleeve clamp. Tighten screws to 144in-lbs.
(16.3Nm)
b. GTX Swing Away and Fixed Front using Short Axle
There is no primary Center of Gravity adjustment with the short axle. See Section 3 for second-
ary adjustment.

from wheelchair. Remove four screw screws (A) atop the axle plate (2 per side) and reposition
into desired location by sliding along frame. Securely tighten all four screws (A) (2 per side).
Tighten screws to 88in-lbs. (10Nm). Ensure that axle plates are positioned symmetrically on
frame.

frame screws (B) (1 per side). Reposition into desired location by sliding along top frame and tele-
scoping in our out of the lower frame. On lower frame adjust plastic sleeve to cover telescoping
tube. Securely tighten all four screws (A) (2 per side) atop the axle plate and two lower frame

c. Reposition Seat Sling Tube- GTX Swing Away

After making Secondary Center of Gravity adjustment the seat sling tube will need to be reposi-
tioned. Loosen the four nuts (A) (2 per side) that hold the seat sling tube to the cross brace
assembly. Slide the seat sling tube either fore or aft to make the seat sling tube even with the rear
frame tube. Tighten the four nuts (A) (2 per side) that hold the seat sling tube to the cross brace
assembly, 88in-lbs. (10Nm). Ensure front seat sling tube position screw (B) lines up with slot in
