Repairing the tyre:
ATTENTION: Explosion hazard!
The wheel will explode if you do not let the air out of the tyre before removing the wheel
rim!
· Always allow the air to escape completely from the wheel before you remove the rim.
· Remove valve cap.
· Exhaust the air from the tyre by pressing the
spring pin in the valve.
· Remove the 5 cylinder head bolts (reverse
side of the wheel, 2) using the Allen key.
· Remove the rim halves from the tyre.
· Remove the inner tube from the tyre.
· Repair inner tube and replace, or insert new.
Note
If the old inner tube is to be repaired and re-used, and has become wet during repair, you can
make replacement easier by sprinkling the inner tube with a little talcum powder.
Note
Refit the wheel in reverse order. Please ensure that the wheel is re-fitted on the same side and
in the same running direction as removed.
· Re-insert the rim halves into the tyre.
· Pump a little air into the tyre.
· Insert the socket head screws into the rim and tighten the screws to 10 Nm.
Make sure the inner tube is not crushed between the two rim halves.

· Check that the tyre is still situated directly and correctly on the rim.
· Screw the valve cap back on.
