Maintenance
Tire Pressure
The rear tire pressure should be kept at 27 psi and the front tire pressure at 25
psi. We recommend a maintenance check up every 12 - 18 months.
If you have a back problem and the ride seems too bumpy, there are two things
that you can do easily to smooth the ride:
1. Consult the tire pressure guide above and subtract three pounds (psi) from
each indicated pressure.
2. A 2” foam cushion can work wonders. You can do this yourself or see us
about a specially made upholstered orthopedic foam seat.
Circuit Breaker
If your wheelchair stops for no apparent reason, it is probably due to the circuit
breakers on the batteries.
# 19 on the Diagram
On rare occasion, it happens that there is a temporary overload on the electric
circuit. If this happens, the circuit breakers will pop out. It is merely a matter
of pressing them back in, and you’re going again. They are white buttons
marked 30. Turn the power off, press the buttons, and turn the power on
again. The circuit breakers can be found underneath the seat of your chair.
Care of Batteries
Rangers have two long lasting 12 volt batteries. They are sealed and are
maintenance free. The charger is fully automatic. There is no danger of
spillage. They will work or transport in any position.
Battery Charging
PLEASE, always follow the procedure in this sequence:
1. Turn the on/off button to the off position.
2. Plug the charger into the wall and leave the charger switch turned OFF.
