5 Setting-up, assembly and repair
a) Screw the gearwheel plates onto the table base with two recessed-head screws each.
Ensure that the sides of the gearwheels face outwards!
b) Screw the Teflon non-slip surface to the table base with four recessed-head screws.
c) Remove a gearwheel from the guiding rod and push it through the base. Then screw the
gearwheel back in.
d) Place the base on the table in such a way so that the joystick is situated over the non-stick
surface and the gearwheels sit on the gearwheel plate.
e) Place one protective cover to the side of the assembled gear wheel plate and then push
the base forward as far as it will go.
f) Check that the top gearwheel is on the last pinion. This is the only way of ensuring that the
two gearwheels run parallel.
g) Place the second protective cover on the gearwheel plate.
