TO SERVICE THE AIR FILTER
1. Remove the air filter cover. See Figure 12.
2. Carefully remove the foam pre-filter (if equipped). Clean
the foam pre-filter with warm soapy water. Squeeze out
excess water. Allow pre-filter to air dry prior to installation.
DO NOT add oil to the pre-filter. Replace the foam pre-
filter if damaged.
3. Carefully remove the paper filter element to prevent debris
from falling into the carburetor.
4. Clean debris from the paper filter by gently tapping the
filter on a hard surface. Do not use compressed air
to clean the paper filter as this could damage the filter.
Replace the paper filter if required.
5. Clean all dirt and debris from the inside of the air filter
box. Be careful not to allow any dirt or debris to enter the
carburetor.
6. Replace the paper filter and foam pre-filter (if equipped).
7. Install the air filter cover. Be sure the air filter cover is
snapped securely in place.
TO SERVICE THE SPARK PLUG
1. Clean the spark plug and reset the gap once a season.
Spark plug replacement is recommended at the start of
each mowing season. See “PRODUCT
SPECIFICATIONS” on page 6 for correct plug type and
gap specifications.
WARNING
Do not check for spark with spark plug removed. Do not crank
engine with spark plug removed.
For good engine operation, the spark plug must be free of
deposits or excessive electrode wear.
2. Remove the spark plug wire and remove spark plug with
a spark plug wrench.
CAUTION
If the engine has been running, the muffler will be very hot. Be
careful not to touch the muffler.
3. Visually inspect the spark plug. Discard the spark plug
if there is apparent wear, or if the insulator is cracked or
chipped. Clean the spark plug with a wire brush if it is to
be reused.
4. Measure the spark plug gap with a feeler gauge. Adjust
plug gap as required by bending electrode. See Figure 13
5. Reinstall the spark plug – starting by hand to prevent
cross-threading.
6. After the spark plug is seated, tighten with a spark plug
wrench an additional ¼ turn (18 ft-lbs )
IMPORTANT:
The spark plug must be securely tightened. An
improperly tightened spark plug can become very hot and
may damage the engine.
