frequently when operating the pump in ex-
tremely dusty areas.
Never use gasoline or low flash point solvents
for cleaning the air cleaner element. A fire or
explosion could result.
IMPORTANT: Never run the engine without the
air cleaner.
Remove the air cleaner cover and remove the
air cleaner filter.
Wash the air cleaner filter in kerosene, then
rinse thoroughly. Allow the element to dry
thoroughly.
Soak the element in clean engine oil, and
squeeze out the excess oil.
Reinstall the air cleaner.
FUEL CLEANER
NOTE: Is recommended that after 25 hours of
use give maintenance to the fuel cleaner, take
the machine to a service center.
A clogged fuel cleaner will reduce the engine
speed and cause unstableness.
SPARK PLUG SERVICE
To ensure proper engine operation, the spark
plug must be properly gapped and free of de-
posits.
1. Remove the spark plug.
NOTE: If the engine has been running, the
muffler will be very hot. Be careful not to
touch the muffler.
2. Visually inspect the spark
plug. Discard it if the insu-
lator is cracked or chipped.
Clean the spark plug with a
wire brush if it is to be re-
used.
NOTE: Measure the plug
gap with a feeler gauge.
The gap should be 0,6 - 0,7
mm. Correct as necessary by
bending the side electrode.
3. Check that the spark plug washer is in good
condition, and thread the spark plug in by
hand to prevent cross-threading.
4. After the spark plug is seated, tighten with
a spark plug wrench to compress the washer.
IMPORTANT: The spark plug must be securely
tightened. An improperly tightened plug can
become very hot and damage the engine.
Never use a spark plug with an improper heat
range.

a separation of 2 mm,
add oil as shown in
the illustration.
2. Start running again
slowly then keep
them with a 2 mm of
separation and oil it

3. Finally, make sure
that both blades
match and add oil at
the tips of the blade.
MUFFLER
