SECTION 1-MAINTENANCE GUIDELINES

SECTION 1-TROUBLESHOOTING A N D MAINTEN A N CE GUIDELINES NOTE: Twice a year, take your wheelchair to a qualified dealer for a thorough inspection and servicing. Regular cleaning will reveal loose or worn parts and enhance the smooth operation of your wheelchair. To operate properly and safely, your wheelchair must be cared for just like any other vehicle. Routine maintenance will extend the life and efficiency of your wheelchair. Initially and at least every six months, follow these maintenance procedures:

Troubleshooting

If pneumatic tyres, check for correct equal pressure. Check for loose stem nuts/screws. Check castor angle adjustment. Check that castor contact ground at the same time.

Maintenance guide lines: Safety Inspection Checklists Initial adjustments should be made to suit the personal body structure needs and preferences of the user. Thereafter follow these maintenance procedures:

Inspect/Adjust Initially (User or Attendant) Wheelchair rolls straight (no excessive drag or pull to one side). Ensure all hardware is tight (see page 7). All fasteners on clothing guards are secure. Arms are secure but easy to release and locking systems engage properly. Adjustable height arms operate and lock securely. Armrest armpad sits flush against arm tube. Seat and/or back upholstery have no rips. Inspect adjustable angle back attaching hardware is securely tightened. Ensure hand grips are secure to backrest canes. Sealed bearings and axle nut tension are correct. No excessive side movement or binding when rear wheels are lifted and spun.

SECTION 1- MAINTENANCE GUIDELINES

Inspect/Adjust Initially (user or attendant) Quick-release axles lock properly (see page 22). Inspect handrims for signs of rough edges or peeling finish. Inspect for broken spokes. Wheel/fork assembly has proper tension when castor is spun. Castor should come to a gradual stop. Wheel bearings are clean and free of moisture. Loosen/tighten locknut if wheel wobbles noticeably or binds to a stop Ensure all castor/wheel/fork/head tube fasteners are secure (see pages 7 & 27). Wheel brakes do not interfere with tyres when rolling. Wheel brakes pivot point are free of wear and looseness. Wheel brakes are easy to engage. Inspect tyres/castors for flat spots and wear. Check pneumatic tyres for proper inflation (recommended tyre pressure is listed on the side wall of the tyre). Clean quick-release axles with a Teflon® lubricant. Ensure axles are free from dirt, lint, etc. Ensure roller bearings are free from dirt, lint, etc. Adjust wheel brakes as tires wear. Clean and wax all parts. Clean upholstery and armrests. Ensure castors are free of debris.

Inspect/Adjust Weekly (User or Attendant) Wheelchair rolls straight (no excessive drag or pull to one side). Quick-release axles lock properly (see page 22). Inspect for broken spokes. Wheel/fork assembly has proper tension when castor is spun. Castor should come to a gradual stop. Inspect tyres/castors for flat spots and wear. Check pneumatic tyres for proper inflation (recommended tyre pressure is listed on the side wall of the tyre). Ensure castors are free of debris.

Inspect/Adjust Monthly (User or Attendant) Inspect seat positioning strap for any signs of wear. Ensure buckle latches. Verify hardware that attaches strap to frame is secure and undamaged. Replace if necessary. Loosen/tighten locknut if wheel wobbles noticeably or binds to a stop.

SECTION 1- MAINTENANCE GUIDELINES

WARNING After ANY adjustments, repair or service and before use, make sure all attaching hardware is tightened securely - otherwise injury or damage may occur.

CAUTION DO NOT over tighten hardware attaching to the frame. This could cause damage to the frame tubing.

Tightening torques The tightening torques stated in the following table are dependent on the thread diameters for the nuts and bolts for which no special values are determined. All values apply to dry and grease-free threads. Thread M4 M5 M6 M8 M10 Tightening torque 3 Nm 6 Nm 10 Nm 25 Nm 49 Nm in Nm maximum

Caution: All other nuts not noted here must be tightened FINGERTIGHT !

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 on section 5.

WARNING 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.

WARNING 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.).

CAUTION As with any vehicle, the wheels and tires should be checked periodically for cracks and wear, and should be replaced if damaged.

5. The wheels, castors and tyres should be checked periodically for cracks and wear, and should be replaced when necessary. 7

SECTION 1- MAINTENANCE GUIDELINES & STABILITY WARNING

6. Regularly check for loose spokes in the rear wheels. If loose, have them adjusted. 7. Periodically check handrims to ensure they are secured to the rear wheels. Refer to Replacing Handrims on section 5. 8. Periodically check castor wheel bearings to make sure they are clean and free from moisture. Use a Teflon® lubricant if necessary. 9. Check upholstery for sagging, rips or tears. 10. Clean upholstery with mild soap and water.

Stability Warning The seat height, seat depth, back angle, seating system/upholstery, size/position of the rear wheels, size/position of the front castors, seating options (e.g. headrest, back bag, …) as well as the user condition directly relate to the stability of the wheelchair. Any change to one or any combination of the nine may cause the wheelchair to increase/decrease in stability.

CASTOR SIZE CASTOR POSITION

Seat-to-floor heights have specific positions depending on rear wheel size, rear wheel position, front caster size/position and seat-to-floor angle. These adjustments MUST be performed by a qualified technician. Refer to sections 5 & 6.
