Rear Wheels; Axles; Pneumatic Tires - Permobil Aero Z 2 Series Owner's Manual

H. REAR WHEELS
I WARNING
Rear wheels are standard components on your wheelchair. The positioning of the rear wheels is a critical factor in locating
the center of balance of your chair. Any change to your rear wheel position will change your center of balance. Therefore,
use extreme caution when making any adjustment to the position of your rear wheels.
1. As you move the rear wheels and axles forward on your chair, you shift the center of balance FORWARD. This means
it is easier for your chair to tip over backward.
2. As you move the rear wheels and axles backward on your chair, you shift the center of balance BACKWARD. This means
your chair is less likely to tip-over backward. However, even if your rear wheels and axles are set as far back as possible,
the chair can still tip-over backward.
3. ALWAYS consult with your health care provider to determine the best rear wheel/axle setup for you based on your
weight and body type and your abilities to control the chair.
4. Once you and your health care provider have determined the best rear wheel/axle setup for you, NEVER change the
setup UNLESS you are sure you are not at risk to tip over.
5. If you do change the rear wheel/axle position, you MUST adjust the positioning of the rear wheel locks to ensure they
work properly to lock the rear wheels. When relocating the rear wheel locks, make sure the locking arm indents the tire
by at least 5 mm when the wheel lock is in the "locked" position.
I. AXLES
I WARNING
Stainless quick-release axles are a standard Permobil Manual wheelchair component. Other axle types are optional
equipment. All Permobil Manual axles are designed to make your rear wheels easy to remove quickly. However, if not used
properly, they can be dangerous.
NEVER use your chair UNLESS you are sure that both rear axles are locked into place in the axle receiver. If an axle is not
fully locked into place, the rear wheel may come off during use of the chair and cause you to fall. You can tell when the axle
is locked into place because the quick-release button in the center of the axle will pop out fully. It is also a good idea to pull
on the wheel to double-check that the axle is securely locked as a final precaution.
J. PNEUMATIC TIRES
I WARNING
Pneumatic rear tires are standard components on Permobil Manual wheelchairs. Pneumatic front tires are optional equipment
on some Permobil Manual wheelchairs.
With pneumatic tires, it is important to maintain the proper inflation. Maintaining the proper inflation will extend the life of your
tires and will reduce the rolling resistance of your chair, making it easier to use.
1. Check your tires WEEKLY for proper inflation. The correct inflation level is imprinted on the tire sidewall.
2. DO NOT use your chair if any of the pneumatic tires are under-inflated or over-inflated.
3. If any tire is under-inflated, the chair may tend to veer to one side, which could cause you to lose control of the chair.
4. If a rear tire is under-inflated, the wheel lock for that wheel may not work properly and may slip, thereby allowing the
wheel to turn unexpectedly.
5. An over-inflated tire may burst, thereby causing a loss of control of the chair.
6. ALWAYS have pneumatic tire inner tubes replaced by an authorized Permobil Manual dealer.
