Filling with air

The recommended air pressure is 36 psi. Overfilling entails the risk of
explosion.
Low air pressure in the tyres produces abnormal wear and reduces the range.
Therefore, check regularly that the front tires have a pressure of 36 psi.
1. Unscrew and remove the plastic caps on the air valves on the drive wheels.
2. Connect the compressed air nozzle to the air valve and adjust the tire
pressure to the prescribed level.
