4. Maintenance activities
4.1 Frame
The frame is powder-coated, resulting in a hard finish. To prevent any rust forming it is important to regularly clean the frame. If
you want to conserve the frame with grease, only use acid free substances. You can treat damaged areas with paint.
4.2 Wheels/tires
The wheels are equipped with ball bearings. Regularly check the rims and tires for any damage (for example cuts, cracks and
bulges). Take care: damaged rims and tires can lead to accidents! The correct tire pressure is shown on the outside of the tire.
If the tires are at the correct pressures the go-kart will be light and easy to handle. If the tire pressures are too low, the tires will
leak quicker and will suffer undue wear and tear. If the tire pressure is too high, the tire can for example, come away from the rim,
resulting in dangerous situations. Remember that in bright sunlight and at high temperatures the tire pressures increase! The
tires must not come into contact with oil, grease or fuel. Make sure that the valve caps are always fit ed on the valves.
4.3 Steering
The steering equipment must be checked every month for the following:
•
Breakage, wear and tear and/or damage to the steering equipment.
•
All the nuts and bolts must be tight.
4.4 Drive mechanism
4.4.1 Chains
The pedal go-kart has a driving mechanism with two chains. Make sure that the chains are
suffici tly oiled so that they can travel freely. If a chain is too tightly tensioned, the go- kart will be more difficult o 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 sp ocket, or there is a chance of damage to the chain housing. Tensioning the
chains takes place as described below.
To tension the front chain: loosen the bolts. Tension the chain by moving the crank axle forwards. Tighten the bolts again. It must
be possible to push the middle of the chain downwards by 1 centimeter. To check this you must remove the chain housing. See
page 9 for instructions.
To tension the rear chain: remove the protective hood. Loosen the nuts of the hub. Tension the chain by moving the hub
forwards. Make sure that the hub remains exactly parallel to the rear axle. Tighten the hub nuts again. The chain has the correct
tension if the middle can be pushed 6 millimeters downwards. See page 9 for instructions.
When both chains must be tensioned, always begin with the rear/short chain.
4.4.2 Crank adjustment after first use
After using the go-kart for several days (intensive use) or for up to two weeks (normal use), 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). A secondary effect of this 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.)
4.5 Plastic parts
The plastic 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.
