Remove the oil filler cap/dipstick. If the level is low, slowly
add oil until oil level registers between high (H) and low (L),
Fig. 3-2 and 3-3 in the Set-Up section.
Repeat Steps 14 & 15 to be sure that the correct oil level has
been achieved.
Once the proper oil level has been confirmed, install the Oil
Fill Cap/Dipstick. Tighten securely
Carefully disconnect spark plug wire from grounding post,
if present.
19. Carefully reconnect the spark plug wire to the spark plug.
NOTE: It is advisable to recheck the oil level after you have
operated the engine for a short while, and the normal engine
operating temperature has been achieved.
i_ WARNING! If the engine has been running, the
muffler, engine head and spark plug will be very hot.
Be careful not to touch any of these components
until they have cooled.
AirFilter(Ifsoequipped)
NOTE: Not all engines have air filters, such as engines used for
snow throwers. Service the air filter if one is present.
Paper filters cannot be cleaned and must be replaced once a
year; more often if used in extremely dusty conditions.
ii_ WARNING! Never use gasoline or low flash point
solvents for cleaning the air cleaner element. A fire
or explosion could result.
NOTE: Never run the engine without the air cleaner. Rapid
engine wear will result.
1. Press the tab on the air filter cover and lift the cover. See
Fig. 6-4.

1. Remove the spark plug boot.
2. Clean the area around the spark plug.
3. Use a spark plug wrench to remove the plug.
_ ARNING! 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 the spark plug
if there is apparent wear, or if the insulator is cracked or
chipped. Replace the plug if the electrodes are pitted,
burned or fouled with deposits.
4. Clean the spark plug with a wire brush if it is to be reused.
5. Measure the plug gap with a feeler gauge. Correct as
necessary by bending side electrode. See Fig. 6-5. The gap
should be set to 0.030 in. (0.76ram).
6. Check that the spark plug washer is in good condition
7. Thread the spark plug in by hand to prevent cross-
threading.
8. After the spark plug is seated, tighten with a spark plug
wrench to compress the washer.
NOTE:When installing a new spark plug, tighten 1/2turn
after the spark plug seats to compress the washer. When
reinstalling a used spark plug, tighten 1/8-1_turn after the
spark plug seats to compress the washer.
NOTE:The spark plug must be securely tightened. An
improperly tightened spark plug can become very hot and
may damage the engine.
