3.3.2 Replacing the tire of the drive wheel
When replacing a tire of a drive wheel neutral should not be switched off, so that the wheel does not turn along.
The tire should be replaced as follows:
• Support the wheelchair so that the wheel is elevated.
• Let the tire run empty completely by pulling out the valve.
• Using tire levers, pull the front of the tire across the edge of the rim.
• Carefully pull the inner tube across the edge of the rim.
• Push the valve from the opening in the rim.
• Pull the inner tube from the tire.
• The whole tire can now be removed.
Now the tires (with repaired or new inner tube) should be assembled as follows:
• Place one side of the tire around the rim.
• Put the valve of the inner tube through the opening in the rim and press the inner tube into the tire.
• Place the tire around the rim.
• Use tire levers to place the tire around the rim: be careful not to damage the inner tube with the tire
levers.
The inner tube must not become jammed between the rim and the tire.
• Pump up the inner tube, see 'technical data'.
• Remove the support from the wheelchair.
The wheelchair is ready to drive again.

3.3.3 Replacing the drive wheel
• See fig. 020702040.
When the rim of a drive wheel is replaced, the neutral should not
be switched off, so that the wheel does not turn along.
Replace this as follows:
• Support the wheelchair so that the wheel is elevated.
• Remove the cap (A) with a screwdriver.
• Bend back the lip on the locking plate (B).
• Using a box spanner with a key width of 17 mm,
remove bolt (C) with the washers that holds the rim
onto the drive unit.
• Pull the wheel (E) off the shaft.
• When the wheel is removed, a key (F)
may come loose or remain in the rim.
This key must be slid into the key way
of the outgoing shaft of the drive unit.
• If there is no key, this will cause drive
problems.
• Behind the key, a bush is slid onto the
outgoing shaft. This bush does not have to be removed.
Now the new wheel can be assembled as follows:
• Put a layer of grease on the outgoing shaft (G) of the drive unit.
• Slide the wheel onto the outgoing shaft of the drive unit.
Attention:
• Make sure that the notch in the rim falls over the key.
• The locking plate has to be replaced: do not use the old one again.
• Screw the bolt with the rings and the locking plate in the thread hole of the outgoing shaft of the drive
unit and tighten the bolt with the box spanner.
• Bend back the lip on the locking plate, so that the bolt is prevented from being unscrewed.
• Remove the support from the wheelchair.
The wheelchair is ready to drive again.
