This procedure is the quickest way to assemble the model correctly.
Practical tips:
Iftheexactassemblyofacomponentcannotbeclearlyidentiedfromthecurrentdrawing,lookatthe
drawings below. The vehicle is often shown from different perspectives, which can make the assembly of
different components more clear.
If required, the assembly instructions can also be downloaded as a PDF in our online shop, either under
product or in the download centre. Pages can then be enlarged on a monitor and details can be seen more
clearly.
Proceeding with the assembly

Before assembling the components to be screwed from the outside, insert the plastic parts between the side mem-
bers. Make sure to use the round head screw to attach the front plastic part.

The tooth pitch between the main gear and bevel gear must be minimal and both gears must be easy to turn. If there
is too much play between the two gears, insert another shim or a thicker one. If a thinner shim is to be used, clamp
the gears.
