damage or wear and re lace if necessary. Check all arts for ro er adjustment.
2. Kee quick release axles free of dirt and lint to ensure ositive locking and ro er
o eration.
3. Clean quick release axles once a week with a Teflon lubricant.
4. Recommended tire ressure is listed on the sidewall of the tire (BAR, KPa or P.S.I.).
5. The wheels, castors and tires must be checked eriodically for cracks and wear and must
be re laced when necessary.
6. Regularly check for loose s okes in the rear wheels. If loose, have them adjusted.
7. Periodically check handrims to ensure they are secured to the rear wheels.
CAUTION
All other nuts not noted here must be tightened FINGERTIGHT!
WARNING
DO NOT use WD-40, 3-in- 1 oil, or other enetrating lubricants on quick-release axles.
Otherwise, binding and/or damage to the wheelchair may occur.
WARNING
DO NOT use your wheelchair unless it has the ro er tire ressure (BAR, KPa or P.S.I.).
DO NOT over inflate the tires. Failure to follow these suggestions may cause the tire to
ex lode and cause bodily harm. The recommended tire ressure is on the sidewall of the
tire.
CAUTION
As with any vehicle, the wheels and tires must be checked eriodically for cracks and wear

8. Periodically check caster wheel bearings to make sure they are clean and free from
moisture. Use a Teflon
®
lubricant if necessary.
9. Check u holstery for sagging, ri s or tears.
10. Clean u holstery with mild soa and water.
1.4 Stability Warning
The seat height, seat de th, back angle, seating system/u holstery, size/ osition of the central
wheels, size/ osition of the front castors, seating o tions (e.g., back bag, …) as well as the user
condition directly relate to the stability of the wheelchair.
Any change to one or any combination of these factors changes the centre of gravity and may
cause the wheelchair to increase/decrease in stability.
Seat-to-floor heights have s ecific ositions de ending on central wheel size, central wheel
osition, front castor size/ osition and seat-to-floor angle.
NOTE: Refer to section Changing Seat-to-floor Height table in the ordinar Action3 NG Service
Manual.
