Suggested Maintenance Procedures

1. Before using your wheelchair, make sure all nuts and bolts are tight. Check all parts
for damage or wear and replace. Check all parts for proper adjustment.
2. Keep quick release axles free of dirt and lint to ensure positive locking and proper
operation. Refer to Adjusting Quick Release Axles paragraph, on section 5.
DO NOT use WD-40, 3-in- 1 oil, or other penetrating lubricants on quick-release
axles. Otherwise, binding and/or damage to the wheelchair may occur.
3. Clean quick release axles once a week with a Teflon lubricant.
DO NOT use your wheelchair unless it has the proper tyre pressure (BAR, KPa or P.S.I.).
DO NOT over inflate the tyres. Failure to follow these suggestions may cause the
tyre to explode and cause bodily harm. The recommended tyre pressure is on the
sidewall of the tyre.
4. Recommended tyre pressure is listed on the sidewall of the tyre (BAR, KPa or P.S.I.).
As with any vehicle, the wheels and tyres should be checked periodically for cracks
and wear, and should be replaced if damaged.
