L. REAR WHEEL LOCKS (OPTIONAL)
If you request them, we will install rear wheel locks at Sunrise.
1. Rear wheel locks are
not designed to slow or stop a moving wheelchair.
Never apply them when your chair is moving. Doing so may cause you to veer
out of control.
•Use wheel locks
only to keep the rear wheels from rolling when your chair is at
a complete stop.
2. 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.
3. Make sure lock arms embed in tires at least 3/8 inch (9.5 mm) when locked. If
you fail to do so, the locks may not work.
M. SEATING SYSTEMS
1. Use of a seating system not approved by Sunrise may alter the center of
balance of this chair. This may cause a fall or tip-over.
2.
Never change the seating system of your chair unless you consult your
supplier first.
N. UPHOLSTERY FABRIC
1. Replace worn or torn fabric of seat sling and seat back as soon as you can.
If you fail to do so, the seat may fail and cause you to fall. Worn fabrics may
increase the potential for a fire hazard.
2. Sling fabric will deteriorate with age and use. Look for fraying, thin spots, or
stretching of fabric at rivet holes. Replace fabric as required.
3. “Dropping down” into sling seat will weaken fabric and result in the need to
inspect and replace sling on a more frequent basis.
4. Be aware that washing may reduce flame retardation of the fabric.

I. PNEUMATIC TIRES
Proper inflation extends the life of your tires and makes your chair easier to use.
1. Do not use this chair if any of the tires are under- or over-inflated. Check
weekly for proper inflation level, as listed on the tire sidewall.
2. Low pressure in a tire may cause the chair to veer to one side and result in a
loss of control.
3. An over-inflated tire may burst.
4.
Never use a gas station air pump to inflate a tire. Such pumps provide air at
high volume, and could cause the tire to burst. To prevent tire damage:
•Use a hand pump (or a
low volume air pump) to inflate tires.
•Use a tire gauge to check pressure.
5. Driving over sharp objects may cause damage to pneumatic tires and tubes.
J. POSITIONING BELTS (OPTIONAL)
Use a positioning belt only to help support your posture. Improper use of such belts
may cause severe injury or death.
1. Make sure you are not at risk to slide down in the wheelchair seat. If this occurs,
you may suffer chest compression or suffocate due to pressure from the belt.
2. A pelvic wedge or a similar device can help keep you from sliding down in the
seat. Consult your health care professional to find out if you need such a device.
3. The belt must be snug, but must not be so tight that it interferes with breath-
ing. You should be able to slide your open hand, flat, between the belt and your
stomach.
4. Make sure you can easily remove the belt in an emergency.
5.
Never use a positioning belt:
•In place of a motor vehicle seat belt. In an accident or sudden stop you may
be thrown from the chair. A positioning belt will not prevent this, and further
injury may result from the belt.
•As a restraint. A restraint requires a doctor’s order.
•On a rider who is comatose or agitated.
K. PUSH HANDLES
1. Push handles provide secure points for an attendant to propel and control the
chair. This helps to prevent a fall or tip-over.
2. Check to make sure push handle grips will not rotate or slip off.
