Cutting Leaves
When cutting is complete, always be sure that
50% of the lawn shows through the cut leaf
cover. This may require one or more passes over
the leaves.
For light leaf coverage, position all wheels at the
same height-of-cut setting.
If there are more than five inches of leaves on
lawn, set the front wheels one or two notches
higher than the rear wheels. This makes it easier
to feed leaves under mower deck.
Walk at a slower mowing speed if leaves are not
being cut up finely enough to be hidden down in
the grass.
If you cut up a lot of oak leaves, you might want
to add lime to your grass in the spring. Lime
reduces the acidity of oak leaves.

Maintenance

POTENTIAL HAZARD
If you leave the wire on the spark plug,
someone could start the engine.
WHAT CAN HAPPEN
Accidental starting of engine could
seriously injure you or other bystanders.
HOW TO AVOID THE HAZARD
Pull wire off spark plug before you do any
maintenance. Also push wire aside so it
does not accidentally contact spark plug.

Servicing Air Cleaner

Normally, clean air cleaner after every 25 operating
hours or every season. More frequent cleaning is
required when mower is operated in dusty or dirty
conditions. Replace air cleaner parts, if very dirty.
EN–11
1. Stop engine and wait for all moving parts to
stop. Pull wire off spark plug.
2. Rotate knob securing air cleaner cover to engine
until cover can be removed. Clean cover
thoroughly (Fig. 14).
3. If the foam element is dirty, remove it from air
cleaner body (Fig. 14). Clean thoroughly.
A. WASH foam element in a solution of liquid
soap and warm water. Squeeze to remove
dirt, but do not twist because foam may
tear. Rinse thoroughly in clear water.
B. DRY by wrapping in a clean rag. Squeeze
rag and foam element to dry. Do not twist.
C. SATURATE element with engine oil.
Squeeze element to remove excess oil and
to distribute oil thoroughly. A damp
element is desirable.
4. Reinstall foam element and air cleaner cover.
IMPORTANT: Do not operate engine without
air cleaner element because extreme engine
wear and damage will likely result.

Replacing Spark Plug

Remove plug after every 25 operating hours and
check its condition. Replace spark plug every 100
operating hours or every season. Use a Champion
RC12YC spark plug or equivalent.
1. Stop engine and wait for all moving parts to
stop. Pull wire off spark plug.
2. Clean around spark plug and remove plug from
cylinder head.
IMPORTANT: Replace a cracked, fouled, or
dirty spark plug. Do not sand blast, scrape, or
clean electrodes because engine damage could
result from grit entering cylinder.
3. Set air gap at 0.030" (0.76 mm) (Fig. 15). Install
correctly gapped spark plug and gasket seal.
Tighten plug firmly to 14 ft–lb (19 N m).
