Maintenance And Repair - Sahara HP7K User Manual

MAINTENANCE & REPAIR
Your power wheelchair is designed for minimal maintenance. However, like any motorized
vehicle it requires routine maintenance.
To keep your HP7C for years of trouble-free operation, we recommend you follow the
following maintenance checks as scheduled.
DAILY CHECKS
1. With the controller turned OFF, perform a joystick check. Make sure it is not bent or
damaged and that it returns to center when you release it. Visually inspect the rubber boot
around the base of the joystick for damage. Do not handle or try to repair it.
2. Visually inspect the controller harnesses. Make sure that they are not frayed, cut or have any
exposed wires.
3. Inspect the battery condition meter on the controller to determine if batteries need to be
charged.
WEEKLY CHECKS
1. Inspect the connections by disconnecting the controller and charger harnesses from the
electronics connector housing. Look for signs of corrosion.
2. Ensure that all parts of the controller system are securely fastened to your power wheelchair.
Do not over tighten any screws.
3. Check for proper tire inflation. Your power wheelchair comes with standard flat-free solid
tires. If your power wheelchair come with optional air tires, make sure to maintain the
pressure of the tires between 30-35 psi.
4.
Check the brakes. This test should be carried out on a level surface with at least three feet of
clearance around your power wheelchair.
To check the brakes ( Your power wheelchair may move slightly when performing this test):
→Turn on the controller and turn down the speed and response adjustment knob.
→After one second, check that the battery condition meter remains on condition.
→Slowly push the joystick forward until you hear the parking brakes click. Immediately release
the joystick. You must be able to hear each parking brake operate within a few seconds of
joystick release.
→Repeat this test of the brake for the back, left and right joystick positions
SEMI-ANNUAL CHECKS
1.
Check the motor brushes. We recommended that your authorized dealer inspect the bushes every
six months, or sooner if your power wheelchair is not operating
smoothly. If inspection determines excessive wear on the brushes, they must be replaced or motor
damage will result.
Warning! Failure to maintain the brushes could void the power wheelchair warranty.
