Steering; Driving Mechanism; Chain; Crank Adjustment - BERG Street-X Mode D'emploi

3.2.3 Steering

The steering equipment must be checked every month for the following:
• Damage and/or wear and tear to steering equipment.
• All the nuts and bolts must be tightened.

3.2.4 Driving mechanism

3.2.4.1 Chain

The go-kart has a driving mechanism with one chain. Make sure that the chains is sufficiently oiled so
that it can run freely. If a chain is too tightly tensioned, the go-kart will be more difficult to pedal and
there is a big chance that wear and tear of the chains and sprocket, among other things, will occur faster.
If a chain is not tight enough, then the chain can easily come off the sprocket, or there is a chance of
damage to the chain housing.
To tension the chain:
• Remove the protective hood.
• Loosen the nuts of the hub.
• Tension the chain by moving the hub.
• Tighten the hub nuts again.
• The chain has the correct tension if the middle can be pushed 6 millimeters downwards.
• 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.

3.2.4.2 Crank adjustment

After using the new product for several days (intensive use) or for up to two weeks (normal use) after
purchase, the mounting bolts with which the left and right cranks are mounted must be tightened
again. Note that they must be 'hand tightened', that is to say with a tightening moment of 30 Nm at
the maximum (it is a normal effect that after a short period of use, as a result of the force applied to the
pedals, the crank assembly settles). An effect when this isn't done regularly, is that a certain amount of
play can occur, which can lead to damage to the crank and the crank axle. This play can be taken up by
tightening the bolts further.

3.2.4.3 Hub

The brake freewheel works like a back-pedalling brake and has a neutral. The brake freewheel can be put
in reverse. The tension of the chain has to be checked every six months.

3.2.5 Plastic parts

The plastic and/or wooden parts must be checked regularly for damage and 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.
