WARNING!
Only for use by children aged 8 years
and older. Instructions for parents
are included and have to be observed.
Read and keep this booklet for future reference.
WARNING
In order to ensure correct
function of the electric
motor, a small quantity of
grease is added during the
manufacturing process. As
grease can melt at high
temperatures, it may dirty
the motor. However, it can
simply be wiped off with a
piece of kitchen paper or a
napkin. The grease used is
neither toxic nor hazardous.

Technical facts and curiosities
The first car in the world with a
combustion engine was built in
Germany by K. Benz in 1876.
It was just under three metres long,
weighed about 250 kg and could
carry two people.
It had a single wheel at the front,
like a tricycle, and a bar for steering,
since a viable solution for moving
two front wheels at the same time
had not yet been devised.

Build a gear rack
Technical facts about gear racks
A gear rack, together with a pinion, converts
rotational motion into linear motion.
In a car's steering system, the rotational motion
of the steering wheel is converted into the linear
motion of the wheels' tie rods, thus steering
the car.

Assemble a manual gearbox
Technical facts on manual gearboxes
In a real car the gears are sealed inside a box, called the gearbox,
which is positioned between the engine axle and the wheel axles.
Ways of changing gear
The lever (see figure) can be used to move the various-sized
cogwheels horizontally on the transmission axle to make them
engage with the cogwheels on the wheel axles, which, depending on
the driving wheel, causes a change in the rotation of the wheels and
a change in the speed of the car.

First gear allows the
wheels to complete a few
rotations and move slowly.
Second gear allows the
wheels to increase the
number of rotations and
therefore move faster.
Note - The gearbox components (gear
lever and cogwheels for first and second
gear) are assembled in Assembly steps 5
and 6.
In this manual gearbox at least one
cogwheel is always connected to the
motor shaft. This means that there is
no neutral. Always turn off the motor
to change gear.
Engaging the gears
In the final assembled model, to
engage and lock 1st gear, move the
gear lever to the orange peg and
press gently on the gear lever.
To move into 2nd gear, turn off the
motor, lift the gear lever, move it to
the blue peg and press gently on the
gear lever.
Restart the motor.
Warning!
Carefully check the position of the rods
with respect to the sides of the car. The
rods should stick out an equal amount
on both sides.

Technical facts and curiosities
1971
In the Apollo 15 moon mission, NASA,
the US space agency, used the first car
with an electric motor on the surface
of the moon.
It weighed 200 kg, had non-rechargeable
chemical batteries and went about
5 km an hour.
The buggy was abandoned on the
moon.
