3.2.2 Wheels / Tires
Regularly check the rims and tires for any damage (for example cuts, cracks and bulges). Attention:
damaged rims and tires can lead to accidents! The tires must not come into contact with oil, grease or
fuel.
3.2.3 Steering
The steering equipment must be checked every month for the following:
• Damage, rust, wear and tear.
• All the nuts and bolts must be tightened.
3.2.4 Chain
The product has a driving mechanism with one chain, which needs proper maintenance. Make sure
that the chain is sufficiently oiled so it can run smoothly.
If a chain is too tightly tensioned, the product will be more difficult to pedal and there is a big chance
that wear and tear of the chain and sprocket, among other things, will occur faster. If a chain is not
tight enough, the chain can easily come off the sprocket, or there is a chance of damage to the chain
housing.
To tension the rear chain:
• Remove the plastic chain guard by loosening the bolts on the front side and the bolt on the rear
side.
• Untighten but do not remove the four bolts on the bottom side near the front sprocket.
• Tension the chain by moving the pedal axle forwards and hold it tight.
• The chain has the correct tension if the middle can be pushed 6 millimeters downwards.
• Tighten the four bolts again. Keep the sprocket wheel parallel to the chain guard.
• Mount the chain guard when the chain has the correct tension.
• The chain guard has to be removed to grease the chain and check the chain tension.
