5. Maintenance activities

5.1 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.

5.2 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 sun-
light 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 fitted
on the valves.

5.3 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.

5.4 Drive mechanism

5.4.1 Crank adjustment when running in a new go-kart

After using the for several days (intensive use) or for up to two weeks (normal
use), the mounting bolts (see Fig. 1) with which the left and right cranks are mount-
ed 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 assem-
bly 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 further.)
