SPARK PLUG
The spark plug is a very important part for good en-
gine effi ciency and special care must be given to it.
Before unscrewing the spark plug, the engine head
must be cleaned with a jet of compressed air to
prevent particles of sand, mud
or any other type of dirt on it from entering
the cylinder.prevent particles of sand, mud or any

- Clean it with a metal brush and check that the dis-
tance between the electrodes is 0.5 -0.6 mm.
This should be done approx. once every 1000
km, while the plug must be changed once every
4000 km.
- Refi t the spark plug, inserting it fi rst by hand and
only using the wrench for the fi nal tightening. - Re-
place the spark plug cover tube (1), ensuring that it
has been inserted correctly.
Whenever the spark plug is changed, check the
pitch and the reach of the thread. If the threaded
part is too short, carbon deposits will build up on
the thread seat thereby risking damaging the en-
gine when the correct spark plug is refi tted.
Only use spark plugs of the recommended type,
see (SPECIFICATIONS), otherwise engine perfor-
mance and life could be adversely affected.
