M.rear Axle - Quickie Q7 Adjustable Mode D'emploi

E N G L I S H
M. REAR AXLE
The most important adjustment on your Quickie wheelchair is the position of the rear axle.
The center of gravity and wheel camber are determined by the axle adjustment.
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
stability 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 (Section K), toe-in/toe-out of the rear
wheels (Section M-3) and the squareness of the casters (Section P). 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 R for instructions on adjusting the wheel locks.
NOTE– Range of adjustment can be limited by chair configuration and options selected.
Quickie Q7 Adjustable
You can adjust your center of gravity position by moving the two axle plate clamps (A) for-
ward or rearward on the seat tube (B). Moving the axle plate clamps forward shortens the
wheelbase and lightens the front end, making your chair more maneuverable. Moving the
axle plates rearward makes the chair more stable and less likely to tip over rearward.
To adjust the center of gravity location, remove both rear wheels. Loosen the 4 screws (C) (2
per side) that secure the axle plates (A) to the seat tubes. Slide both axle clamps forward or
rearward along the seat tube to the desired position. Make sure both sides are adjusted sym-
metrically before tightening screws. Tighten screws to 62 in-lbs. (7 Nm).
Once the axle plate clamps are secured, attach the rear wheels. Occupy the chair and
maneuver it with a spotter to get a feel for the new adjustment.
Quickie Q7 Active Rigid
NOTE– Adjusting your chair's center of gravity will require re-adjusting the location of the wheel locks (if
provided). See Section R for instructions on adjusting the wheel locks.
NOTE– Active Camber Setup: Axle plate is welded per Center of Gravity requirement, per order.
NOTE– Camber clamp to be centered on camber tube mount except when the Center of Gravity is set at
0.5" or 4.0".
You can adjust the center of gravity position by moving the camber tube clamps (D) forward
or rearward on the camber tube mount. Moving the camber tube clamps forward shortens
the wheelbase and lightens the front end, making your chair more maneuverable. Moving the
camber tube clamps rearward makes the chair more stable and less likely to tip over rear-
ward.
To adjust the center of gravity location, remove both rear wheels. Remove the 4 screws, (E)
(2 per side) that secure the camber tube clamp to the camber tube mount (F). Slide both
camber tube clamps forward or rearward (keeping even on both sides) to the desired posi-
tion insuring that holes in the camber tube clamp line up with the camber tube mount. Make
sure both sides are adjusted symmetrically before tightening screws. Tighten screws to 62 in-
lbs (7 Nm). Once the camber tube clamps are secured, attach the rear wheels. Occupy the
chair and maneuver it with a spotter to get a feel for the new adjustment.

2. Wheel Camber
Wheel camber, shown as angular relationship (G), provides greater side-to-side stability due
to the increased width and angle of the wheelbase. It also allows for quicker turning and
greater access to the top of the handrims.
Wheel camber is determined by pairs of interchangeable camber plugs which are available
from your authorized supplier in 0º, 3°, and 6º angles.
