If you use parts or make changes not authorized by Sunrise it may create a safety hazard and will void the Warranty.

A. ANTI-TIP LEVERS

Never remove or alter anti-tip levers. They help keep your chair from tipping over backward in normal use. Make sure rubber rollers are in good condition.

B. ARMRESTS

Armrests detach and will not bear the weight of this chair.

1.Never lift this chair by its armrests. They may come loose or break.

2.Lift this chair only by non-detachable parts of the main frame.

C.BATTERIES

1.Only deep cycle sealed case construction batteries should be used in this device.

2.To prevent an acid spill, always keep batteries upright (wet batteries).

3.Never smoke or hold an open flame near batteries. They are a known explosion hazard.

4.Always wear rubber gloves and safety glasses when you handle batteries.

5.Read all of section XI Batteries before attempting to change, or charge batteries.

D.CUSHIONS & SLING SEATS

1.Quickie sling seats, standard foam cushions, and other body supports are not designed for the relief of pressure.

2.If you suffer from pressure sores, or if you are at risk that they will occur, you may need a special seat system or a device to control your posture.

•Consult your doctor, nurse or therapist to find out if you need such a device for your well-being.

E.FASTENERS

Many of the screws, bolts and nuts on this chair are special high-strength fasteners. Use of improper fasteners may cause your chair to fail.

1.Only use fasteners provided by Sunrise.

2.If fasteners become loose, tighten them as soon as you can.

3.Over- or under-tightened fasteners may fail or cause damage to chair parts.

•See Section IX for proper torque settings.

F.FOOTRESTS

1.At the lowest point, footrests should be at least 2 1/2 inches off the ground. If set too LOW, they may “hang up” on obstacles you can expect to find in normal use. This may cause the chair to stop suddenly and tip forward.

2.To avoid a trip or fall when you transfer:

•Make sure your feet do not “hang up” or get caught in the space between the footrests.

•Avoid putting weight on the footrests, as the chair may tip forward. •Remove or swing the footrests out of the way, if possible.

3.Never lift this chair by the footrests. Footrests detach and will not bear the weight of this chair. Lift this chair only by non-detachable parts of the main frame.

G.MOTOR LOCKS

1.Do not engage or disengage motor locks unless power to the chair is off.

2.Be aware that the chair will not have brakes when motor locks are in the free-wheel position.

3.Make sure that the person pushing the chair has full control when motor locks are disengaged.

H.ON/OFF SWITCH

1.Never use the ON/OFF switch to stop the chair except in an emergency. This will result in an abrupt stop, and may cause you to fall.

2.To slow your chair to a stop, return the joystick to neutral.

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.
