    13.1.2 CHECK CHAIN TENSION WARNING: Excessive chain tension can lead to increased wear on the chain, chain sprocket and possibly other components tearing or even breaking them. Too low chain tension can cause the chain to jump off the chain pinion or sprocket. If this is the case, the rear wheel can block or the motor may be damaged.

    60.4 13.1.3 SETTING CHAIN TENSION WARNING: A rear wheel that is not properly mounted can lead to damage to the components and accidents The chain tension is adjusted by loosening the rear wheel axle and is set with the nuts via the two chain tensioners.

  • Page 23: Tires

    13.2 TIRES 13.2 AIR PRESSURE WARNING: If the tire air pressure is too low, the wear increases and the tire valve can tear off. Excessive tire air pressure leads to over-stressing of the material and may cause the tire to burst. Therefore, check the air pressure of the cold tires before driving.

  • Page 24: Checking Brake Pads

    WARNING: Worn brake discs reduce braking effect, which can lead to accidents, injuries and damage to the components! Therefore, check the brake disc thickness regularly! To do this, measure the thickness of the brake discs on the front and rear wheels in several places. NOTE: Each braking process reduces the brake disc thickness in the area between the brake pads.

  • Page 25: Changing Brake Fluid

    WARNING: Worn brake discs reduce braking effect, which can result in accidents, injuries and damage to components. Therefore, check the brake pad thickness regularly! To do this, measure the strength of the brake pads on the front and rear wheels. NOTE: Each braking process reduces the brake pad thickness in the area between the brake pads.
