R. CASTERS
NOTE– Setting the wheelchair on a very flat table or a workbench makes this setting more accurate.
NOTE ON TORQUE SETTING– A torque setting is the optimum tightening which should be made on a par-
ticular fastener. Use proper torque settings when specified.
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
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)
away from vertical, your casters require re-squaring.
2. Re-squaring Your Casters
Gently pry cap (A) off of both caster tubes. Locate the set screw (B) inside the right caster tube and
loosen using an 8mm Allen wrench. Do not remove the set screw. Simply loosen it enough to allow the
teeth on the upper and lower splines (C) 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 con-
tact 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)
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 set screw (B) to secure the spline mating position. The set
screw should be tightened to 192 in-lbs. (21.7 Nm) to ensure that it does not loosen during use.
Record the teeth engagement position of the splines on the right fork, and adjust the left fork in a similar
fashion to the same position. Reassemble both casters, and re-check that they are square. Replace caps.
S. ANTI-TIP TUBES (OPTIONAL)
Quickie recommends anti-tip tubes for all wheelchairs.
Use a torque setting of 100 in.-lbs. when setting up the anti-tip tubes.
1. Inserting Anti-Tip Tubes Into Receiver
a. Press the rear anti-tip release pin (A) on the anti-tip tube so that both release pins are drawn
inside.
b. Insert into the anti-tip tube receiver.
c. Turn the anti-tip tube down until release pin is positioned through the receiver mounting hole (B).
d. Insert second anti-tip tube the same way.
NOTE– If using standard or amputee axle plate, an adapter plate will be necessary to mount anti-tip
receiver to axle plate
