D. FASTENERS
WARNING
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 immediately.
3. Over- or under-tightened fasteners can cause damage to
your chair or it’s components.
E. FOOTPLATE & FOOTRESTS
WARNING
1. At the lowest point, footrests should be at least 2 1/2 inches
(65 mm) 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.

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.
4. Make sure that the chair is on level ground when motor
locks are disengaged.
G. ON/OFF SWITCH
WARNING
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.
H. PNEUMATIC TIRES
WARNING
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.
4.
An over-inflated tire may burst.
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 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.
