7.3. CLEANING THE AIR FILTER
A dirty air filter will restrict the flow of air to the
carburettor thus losing power, working less effectively
and increasing the consumption of petrol. Remember
to always check the cleanliness of the air filter,
especially in areas of extreme dustiness.
Cleaning the air filter:
1. Unscrew the wing nuts that hold the air filter cover.
2. Remove the air filter cover.
3. Remove the air filter and grille.
4. Clean the air filter with tepid
soaped water.
5. Let the air filter dry.
6. When the air filter is dry,
dampen it lightly with some
oil (the oil increases the capacity of the filter to
retain small particles).
7. Replace the air filter and grille into
place.
8. Replace the air filter cover.
9. Screw back on the wing nuts.
Note: The machine should never run without the air
filter.

Dismounting the spark plug:
1. Remove the spar plug cap.
2. Insert a spark plug key.
3. Unscrew the spark plug.
Mounting the spark plug:
1. Replace the spark plug in place.
