N.rear Wheel Spacing; O.casters - Quickie Q7 Adjustable Owner's Manual

Q 7
Before tightening the screws (G), make certain that the camber tube is centered left-to-right
relative to the wheelchair frame and the flat portions underneath outer camber tube clamp
are parallel side to side. The end of the camber tube should be flush with the outer most
portion of the camber tube clamp. Torque the fasteners to 62 in-lbs. (7 Nm).
NOTE– When turning the 4-Link Rear Suspension, always make one change at time and write down the
change. This takes patience, but allows you to understand how each change affects the ride of the
wheelchair in conjunction with rear suspension.
NOTE– Lower shock mount is designed to have a loose feel, this is by design to allow for proper suspension
travel.
NOTE– Never remove the barrel nut (I) that connects camber clamp to the shock camber clamp.
3. Maintenance
The maintenance requirements listed below should be followed along with general wheel-
chair maintenance called out in Section XI.
a. Do not apply lubrication to shock end bushings or coils.
b. You can apply lubrication to the link ends after cleaning with a mild soap and soft
brush.
c. Use a soft brush to clear any dirt or debris from coil system.
d. Never use a high-powered washer for cleaning the 4-Link Rear Suspension.
O. REAR WHEEL SPACING
Rear wheel spacing is measured as the gap between the top of the rear wheels and the back-
canes, and is shown as dimension X
depending on the options chosen.
NOTE– When setting the rear wheel spacing only make adjustments to one side of the chair at a time.
Loosening both sides will undo the toe setting.
To adjust the rear wheel spacing, the camber inserts (A) telescope in and out of the camber
tube (B) with hard stops at the outer limit of travel. On the left side of the chair, loosen
screws (C) (the ones closest to the camber tube). Slide the camber insert in or out to estab-
lish the required wheel spacing. Tighten screw to 62 in-lbs. (7 Nm). Repeat on the right side
of the chair, matching the wheel spacing set on the left side.
P . CASTERS
NOTE– Setting the wheelchair on a very flat table or a workbench makes this setting more accurate.
1. Adjusting Caster Angle
Checking for Caster Squareness:
Your Quickie wheelchair leaves the factory with the casters adjusted square. Any time you
change your wheelchair rear axle height, rear tire size, center of gravity position or camber
tube, you should check that the casters are still square. A caster that is not square will result
in the caster lifting off the floor as it rotates around the stem bolt
front of the wheelchair up and down. Check for squareness by placing your wheelchair on a
flat, horizontal surface. Rotate both forks so that the casters are towards the rear of the
wheelchair. Place a square or pocket level against the flat surface on the rear of the fork and
note whether this surface is vertical (square)
from vertical, your casters require re-squaring.
2. Re-squaring Your Casters
Locate the screw (D) inside the right caster tube and loosen using a custom 6mm Allen
wrench. Do not remove the screw. Simply loosen it enough to allow the teeth on the upper
and lower splines (E) to clear one another. With the stem bolt loosened, the caster fork
should pivot freely. Place the wheelchair on the floor so that the two rear wheels and left
caster contact the floor. Place some weight in the seat towards the rear to help stabilize the
chair. Place a square or pocket level against the flat surface of the fork and pivot the fork until
it is vertical (square) 36 . With the fork vertical, engage the teeth of the two splines to the
closest mating position. Make certain that the teeth are properly engaged and not crossed.
Shine a bright light behind the mating spline teeth and check for proper teeth engagement.
Tighten the screw (D) to secure the spline mating position. The screw should be tightened to
