3.3.5 Tire repair swivel castors
Repairing a leaking tire should be done as follows:
• Support the wheelchair so that the wheel is elevated.
• Let the tire run empty completely by pulling out the valve.
• Loosen the locking nut using a box spanner with a key width of 13 mm and stop the bolt with the same box
spanner.
Now the wheel can be slid out of the fork. Watch the washers that come free: collect them so they will not be
lost.
• Loosen the Allen bolts from the rim halves using an Allen key with a key width of 5 mm.
Now the rim halves can be taken apart.
This released both tires and the valve can be slid out of the rim half.
• Remove the inner tube from the tire.
• Repair the inner tube or replace it.
Now the tire (with repaired or new inner tube) should be assembled as follows:
• Place the (repaired or new) inner tube in the tire.
• Put the valve through the opening in the rim half.
• Slide the other rim half over the hub of the wheel.
• Screw both rim halves with the bolts and locking nuts to each other.
Attention:
• Locknuts may not be used again – use new ones when replacing.
• The inner tube must not be jammed between the two rim halves.
• Tighten the locking nuts and hold the bolts.
• Pump up the tire.
• Replace the wheel in the fork, in the reverse order of disassembly.

3.3.6 Replacing the swivel castor
• See fig. 020703030.
Replace the swivel castor as follows:
• Support the wheelchair so that the swivel castor is
elevated.
• Remove the plastic cover cap (A) with a screwdriver.
• Loosen nut (B) using a box spanner with a spanner
width of 19 mm.
• Now the complete swivel castor (C) can be removed
from the ball head.
Watch the rings under the nut so that they are not
lost.
Now the (new) swivel castor can be placed in the reverse
order.
Adjusting the ball head:
• Tighten nut (B) until the fork starts
moving.
This way, the front wheel is prevented from vibrating.
