BERG Buzzy Nitro

3.2.4 Chain

The product has a driving mechanism with one chain, which needs proper maintenance.

Make sure that the chain is suciently oiled so it can run smoothly.

If a chain is too tightly tensioned, the product will be more dicult 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 o the sprocket, or there is a chance of damage to the chain

housing.

To tension the 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.

3.2.5 Plastic parts

The plastic parts must be checked regularly for damage a breakage.

In the case of breakage you must immediately replace the part concerned with an original part, in

order to guarantee the safety of the user.
