Quantum J4E - Care and Maintenance

Care and Maintenance
Your J4E is a sophisticated power chair. Like any motorized
vehicle, it requires routine maintenance checks. You can
perform some of these checks, but others require assistance
from your Quantum Rehab Provider. Preventive maintenance
is very important. If you follow the maintenance checks in
this section as scheduled, you can help ensure that your
power chair gives you years of trouble-free operation. If you
have any doubt as to your power chair’s care or operation,
contact your Quantum Rehab Provider.
Do not service the power chair when the seat is occupied.
Your power chair, like most electrical equipment, is
susceptible to damage from the elements. Avoid damp areas
of any kind.
Direct or prolonged exposure to water or dampness could
cause the power chair to malfunction electronically and
mechanically. Water can cause electrical components
to corrode and the chair’s frame to rust. Power chairs
should be examined periodically for signs of corrosion
caused by water exposure, bodily uid exposure, or
incontinence. Damaged components should be replaced
or treated immediately.
Should your power chair come in contact with water:
1. Dry your power chair as thoroughly as possible with a
towel.
2. Allow your power chair to sit in a warm, dry place for
12 hours to allow unseen water to evaporate.
3. Check the joystick operation and the brakes before
using your power chair again.
4. If any inconsistencies are found, take your power
chair to a Quantum Rehab Provider. Power chairs that
are frequently exposed to sources of water, such as
incontinence, should be inspected often for corrosion
and electronic components may need to be replaced
frequently.
Temperature
 Although your power chair can withstand short-term
storage temperatures between -40°F (-40°C) to 149°F
(65°C), it is recommended that long-term storage
temperatures be between -13°F (-25°C) and 122°F
(50°C). Ideal storage conditions are 68°F (20°C) to
70°F (21°C) wherever possible, but we realize that
is not always feasible due to di󰀨erent climates and
environments.
 In extremely cold temperatures the batteries may freeze.
The specic temperature at which they freeze depends
on a number of factors, such as battery charge, usage,
and composition of the batteries (e.g., AGM or Gel-Cell).
General Guidelines
 Avoid knocking or bumping the controller, especially the
joystick.
 Avoid prolonged exposure of your power chair to extreme
conditions, such as heat, cold, or moisture.
 Keep the controller clean.
 Check all connectors to ensure that they are all tight and
secured properly.
 Make sure pneumatic tires are inated to the psi/bar/kPa
air pressure rating indicated on the tire.
Make sure your tires are inated to the psi/bar/kPa
air pressure rating indicated on the tire for pneumatic
tires. Do not under inate or over inate your tires. Low
pressure may result in loss of control, and overinated
tires may burst. Overinating tires can cause them to
explode.
Do not use a high pressure hose to inate your tires.
 Use a rubber conditioner on the tire sidewalls to help
preserve them.
Never use a rubber conditioner on the tread area of the
tires; doing so may make the tires slippery and cause
your power chair to skid.
 All wheel bearings are prelubricated and sealed. They
require no subsequent lubrication.
 If your power chair has a body shroud with a glossy
nish, the body shroud has been sprayed with a clear
sealant coating. You can apply a light coat of car wax to
help it retain its high-gloss appearance. If your power
chair has a body shroud with a matte nish, use ONLY
products developed for matte-nish paint. Do not use
wax, detail spray, ArmorAll®, or any product made for
glossy paint.
Carefully choose the correct product to protect the
nish of your power chair's shroud(s). ONLY products
developed for matte-nish paint should be used on
shrouds with a matte nish. Failure to follow this warning
may result in damage to the shroud's matte paint nish.
 Check all electrical connections. Make sure they are tight
and are not corroded. Batteries must sit at within the
battery tray, with the battery terminals facing rearward.
Refer to the battery wiring label for the correct wiring
layout.
