CARE AND MAINTENANCE
Your R-4000 is a sophisticated power chair. Like any motorised vehicle, it requires routine maintenance checks. You can
perform some of these checks, but others require assistance from your Quantum Rehab Dealer. 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 Dealer.
WARNING! 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.
WARNING! 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 fluids 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 your Quantum Rehab Dealer. 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
!
Some of the parts of your power chair are susceptible to extreme changes in temperature. Always keep your power
chair between the temperatures of -8° C (18° F) and 50° C (122° F).
!
In extremely cold temperatures the batteries may freeze. The specific 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).
!
Temperatures above 50° C (122° F) may cause your power chair to operate at a reduced speed. This reduced speed
is a safety feature built into the controller that helps prevent damage to the motor and other electrical components.
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 drive tyres are inflated to the psi/bar/kPa air pressure rating indicated on each tyre.
WARNING! Make sure pneumatic tyres are inflated to the psi/bar/kPa air pressure rating indicated
on the tyre. Low pressure may result in loss of control, and overinflated tyres may burst.
Overinflating tyres can cause them to explode.
WARNING! Do not use a high pressure hose to inflate your tyres.
!
Use a rubber conditioner on the tyre sidewalls to help preserve them.
WARNING! Never use a rubber conditioner on the tread area of the tyres; doing so may make the
tyres slippery and cause your power chair to skid.
