MAINTENANCE

Tires. The wheels are interchangeable, i.e., they can be assembled either in front or rear,
provided, that they are inflated to the pressures prescribed. For replacing a flat tire:
- Unscrew the four nuts which secure the wheel;
- Pull the latter sideways off the studs; and
- Repair the tube or fit on the spare wheel.
Ensure that the spring washers are present when reassembling wheel. Tighten nuts
diagonally and evenly.
For removing the inner tube, first deflate it then unscrew the six nuts on the wheel, so that the
two halves of the rim fall apart (see Fig. 17).
Tire pressure should be 1.25 to 1.40 Kg/cm2 (18 to 20 psi) on the rear wheel, and 1.00 to 1.1
Kg/cm2 ( 14 to 16 psi) on front wheel. When the machine is ridden by two persons, the
pressure of the rear tire should be increased to 2.0 to 2.2 Kg/cm2 (29 to 31 psi).
