N. UPHOLSTERY FABRIC
1. Replace worn or torn fabric of seat and seat back as soon as you can.
If you fail to do so, the seat may fail.
2. Sling fabric will weaken with age and use. Look for fraying or thin spots or
stretching of fabrics at rivet holes.

J. QUICK-RELEASE AXLES
1. Do not use this chair UNLESS you are sure that both quick-release rear axles are
locked. An unlocked axle may come off during use and cause a fall.
2. An axle is not locked until the quick-release button pops out fully. An unlocked
axle may come off during use, resulting in a fall, tip-over or loss of control and
cause severe injury to the rider or others.
• Quick-Release Axles should be inspected for function and any signs of
wear or bending. Replace as necessary.

may occur and cause severe injury to the rider or others.
K. REAR AXLES
A change in the set-up of the rear wheels will affect the center of balance of
your chair.
1. The farther you move the rear axles FORWARD, the more likely it is that your
chair will tip over backward.
2. Consult your doctor, nurse or therapist to find the best rear axle set-up for your
chair. Do not change the set-up UNLESS you are sure you are not at risk to tip over.
3. Adjust the rear wheel locks after you make any change to the rear axles.
a. If you fail to do so, the locks may not work.
b. Make sure lock arms embed in tires at least 1/8" (3 mm) when locked.
If you fail to heed these warnings damage to your chair, a fall, tip-over or loss of control
may occur and cause severe injury to the rider or others.
L. REAR WHEEL LOCKS
Rear wheel locks are NOT designed to slow or stop a moving wheelchair. Use the rear wheel
locks only to keep the rear wheels from rolling when your chair is at a complete stop.
1. NEVER use rear wheel locks to try to slow or stop your chair when it is
moving. Doing so may cause you to veer out of control.
2. To keep the rear wheels from rolling, always set both rear wheel locks when you
transfer to or from your chair.
3. Low pressure in a rear tire may cause the wheel lock on that side to slip and
may allow the wheel to turn when you do not expect it.
4. Make sure lock arms embed in tires at least 1/8" (3 mm) when locked. If you fail
to do so, the locks may not work.
If you fail to heed these warnings damage to your chair, a fall, tip-over or loss of control
may occur and cause severe injury to the rider or others.
