Example of spokes guards

7. Maintenance, inspections and controls

Weekly:

  • ✓ Check the tyre pressure. Each tyre shows on the lateral bands the maximum pressure for which they are designed. A flat tyre affects the efficiency of brakes and the agility of the wheelchair.

  • ✓ Check the efficiency of the quick-release axle (see 5.1, “Quick-Release Check (HAPPY STANDING)”) and if necessary proceed with the lubrication of axle and bushes.

  • ✓ Check the tension of the backrest upholstery to maintain a comfortable position.

Quarterly:

  • ✓ Check the tightness of all the devices' screws.

  • ✓ Check the perpendicularity of the front fork support screws.

  • ✓ Check the wear of the front wheels. Solid wheels might be worn to the point of affecting the overall wheelchair front setup. In this case adjust the front fork assembly or replace the wheels (see [replace_front_wheel]).

  • ✓ Check the efficiency of the bearings. Replace any stuck bearings if necessary (see [replace_bearings_rear], [replace_bearings_front] and [replace_bearings_fork]).

  • ✓ Check the efficiency of the brakes and, in case, adjust them. If the knurled pin has to be replaced, consult authorised personnel.

  • ✓ Lubricate moving parts such as hinges, bearings and quick-release axles. It is suggested to use silicon oil, which is efficient and doesn’t smear.

Important Only choose original parts when purchasing accessories or spare parts.
Contact OFFCARR if you can’t find original spare parts on the market elsewhere.
Important It is recommended to refer only to authorized and qualified personnel to perform maintenance programs, adjustments, and to replace components or accessories.

Assembly

  • Place the new bearing B1 on the inside of the hub so that it is coaxial with the hub and apply pressure to fit it into place.

  • Before placing the second bearing B2, insert shaft A in a way that you can use it as a guide for the second bearing and to ensure the coaxiality of the system.

7.3. Quick extraction devices (HAPPY STANDING)

7.3.1. Check

The quick extraction axles are shipped already checked and adjusted. However, it is recommended to periodically verify the effectiveness of their operation.

  • Make sure that the X button is fully released once the wheel is correctly mounted.

  • Check the effectiveness of the latch by trying to pull the wheel outward without pressing the button and make sure it does not slip off.

Wheel removal diagram

7.3.2. Adjustment

If necessary, it is possible to adjust the axle to eliminate any play between the wheel and the frame or to complete the release of the button once the wheel is inserted.

Wheel pin scheme

  • If the quick-release button is not completely relaxed when the wheel is inserted in the frame, it is necessary to extend the useful length of the L axle by partially unscrewing the Y nut.

  • If once the wheel has been inserted into the frame, there is play between the frame and the wheel itself, it is necessary to reduce the useful length of the L axis by partially tightening the Y nut.

Note The Y nut thread has a pitch of 1 mm, therefore the unscrewing or screwing of one turn involves the elongation or reduction of 1 mm. In case of adjustment, it is advisable to proceed with successive adjustments of ¼ of a turn at a time.
