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 pre–cleaner after every 25
operating hours or every season. Clean the paper
cartridge after every 100 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.
IMPORTANT: Do not operate engine without
air filter elements; extreme engine wear or
damage will occur.
Note: Tipping mower on wrong side to
service underside of mower may cause
damage to air filters.
1. Stop engine and pull wire off spark plug
(Fig. 10).
2. Remove two (2) knobs securing air cleaner cover
to engine (Fig. 16).
3. Lift cover off. Clean cover thoroughly.
4. Carefully remove pre–cleaner. If pre–cleaner is
dirty, carefully wash it in a solution of liquid
soap and warm water. Rinse in clear water.
Allow to dry thoroughly before using.
5. If paper cartridge is dirty, clean the paper filter
by tapping it gently on a flat surface. If very
dirty, replace cartridge.
IMPORTANT: Do not oil pre–cleaner or
paper cartridge. Do not use pressurized air to
clean paper cartridge.
6. Reinstall pre–cleaner over paper cartridge.
Reinstall air cleaner cover and tighten securely
in place with two (2) knobs.
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 (Fig. 10).
2. Clean around spark plug and remove plug from
cylinder head.
