The correct tension of the chain
The chain should not be too tight. It should hang loose. Without effort you should be
able to move the chain up and down, half a centimetre approximately.
To keep the chain tension correct, the back wheel
axle is adjusted. Follow the instructions below:
1. Slightly loosen the nuts of the back wheel
axle, so that it can move backwards and
forwards.
2. Slightly loosen the nut of the bracket, so it
can also move.
3. By tightening the adjusting nuts
at both
sides
, the back wheel slowly moves
backwards. Tighten the adjusting nuts in
such a way that the chain is hanging loose,
as described above.
4. At the same time, make sure that the wheel is
straight and positioned in the centre of the frame,
as illustrated. Not to the left or to the right.
5. Slightly tighten the nuts of the back wheel axle.
6. Check whether the chain tension is correct
and whether the wheel is straight and in
the centre of the frame.
7. Tighten all the nuts again
.
The right lubricant
The chain should be cleaned and maintained at regular intervals (every 3 months
approximately). Only use special chain grease or Tevlon spray. This is the only way
to make sure that the chain will run smoothly, will stay water resistant and will not
rust. Wipe the chain with a cloth, treat it with grease or spray and remove any excess
lubricant with a rag.
Other parts should not be treated with a lubricant.
Checking the rim
Due to the combined action of the brake and the rims, not only the brake lining but
also the condition of the rim is important. For this reason the rim should be checked at
regular intervals, for example when you inflate the tyres. The presence of fine cracks
in the spoke punches or deformation of the rim when there is higher air pressure,
indicate more serious wear and tear. In that case the rim should be replaced,
because it can lead to loss of brake function or even a crack in the rim, which can
lead to all kinds of dangerous consequences.
