4. Setting Contact Pressure
Contact pressure is crucial to ensure consistent power transmission even in bad
weather conditions. It needs to be adjusted, especially if the tyre pressure changes,
in order to prevent increased wear. The contact pressure is regulated by the tyre
pressure and the positioning of the drive unit.
ATTENTION!
Check the contact pressure at regular intervals to prevent the rear
wheel from slipping and to avoid increased tyre wear. The motor
must not slip under any circumstances!
Push the motor t in the highest position till
it touches the tire.
