3.4.1 Tyre repair for swivel wheels
Repair a flat tyre as follows:
•
Support the wheelchair so that the wheel is off the ground.
•
Pull out the valve to completely deflate the tyre.
•
Loosen the wheel bolt using an open-ended spanner with a width of 13 mm and stop the bolt with the same open-
ended spanner.
Slide the wheel out of the fork. Watch the washers that come free: collect them so they will not be lost.
•
Loosen the wheel bolts using an Allen key with a width of 5 mm. Separate the rim halves.
This will release both tyres, allowing the valve to be slid out of the rim half.
•
Remove the inner tube from the tyre.
•
Repair the inner tube or replace it.
Refit the tyre (with repaired or new inner tube) as follows:
•
Place the (repaired or new) inner tube in the tyre.
•
Stick the valve through the opening in the rim half.
•
Slide the other rim half over the hub of the wheel.
•
Screw both rim halves together with the Allen bolts.
The inner tube must not be jammed between the two rim halves.
•
Tighten the wheel bolts.
•
Pump the tyre up.
•
Replace the wheel in the fork, in the reverse order of disassembly.
