Changing inner tubes

1. Block up the wheelchair and let out the air.

2. Pull the tire off the wheel rim.

3. Change the punctured inner tube.

4. Replace the tire on the wheel rim and fill with air.

Low air pressure in the tires produces abnormal wear and reduces the range.
Therefore, check regularly that the tires have a pressure of 29 psi (0.2 MPa).

1. Unscrew the plastic caps on the air valves of the front and rear tires. 

2. Connect the air nozzle to the valve and adjust the tire pressure to the stipu-

lated level.

Fig. 39. Filling valve

The recommended air pressure is 29 psi (0.2 MPa). Overfilling entails the
risk of explosion.
