• To read proper level, tighten engine oil cap
each time.
• Reinstall engine oil cap and tighten.
• Change the oil after every 25 hours of
operation or each season. You may need
to change the oil more often under dusty,
dirty conditions.
GAS
• Under certain conditions, such as very
tall grass, it may be necessary to raise
the height of cut to reduce pushing effort
and to keep from overloading the engine
and leaving clumps of grass clippings. It
may also be necessary to reduce
ground speed and/or run the lawn
mower over the area a second time.
• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of 87
octane. Do not mLxoil with gasoline.
Purchase fuel in quantities that can be used
within 30 days to assure fuel freshness.
• For extremely heavy cutting, reduce the
width of cut by overlapping previously
cut path and mow slowly.
• For better grass bagging and most
cutting conditions, the engine speed
should be set in the fast position.
• When using a rear discharge lawn
mower in moist, heavy grass, clumps of
cut grass may not enter the grass
catcher. Reduce ground speed (pushing speed) and/or run the lawn mower
over the area a second time.
• If a trail of clippings is left on the right
side of a rear discharge mower, mow in
a clockwise direction with a small
WARNING:
Experience indicates that
alcohol blended fuels (called gasohol or using
ethanol or methanol) can attract moisture
which leads to separation and formation of
acids during storage. Acidic gas can damage
the fuel system of an engine while in storage.
To avoid engine problems, the fuel system
should be emptied before storage of 30 days
or longer. Drain the fuel tank, stad the engine
and let it run until fuel lines and carburetor are
empty. Use fresh fuel next season. See
Storage Instructions for additional information.

MULCHINGMOWING
TIPS
• For best results, a_ust the lawn mower

off only the top one-third of the grass blades.
if the lawn is overgrown it will be necessary
to raise the height of cut to reduce pushing
effort and to keep from overloading the
engine and leaving clumps of mulched
grass. For extremely heavy mulching,
reduce your width of cut, mow slowly and
raise the rear of the lawn mower one wheel
IMPORTANT:
For best performance, keep
mower housing free of built-up grass and trash.
Clean UNDERSIDE OF MOWER HOUSING
after each use. See "Cleaning" in
MAINTENANCE
section of this manual.
• The special mulching blade will recut the
grass clippings many times and reduce
them in size so that as they fall onto the
lawn they will disperse into the grass and
not be noticed. Also, the mulched grass will
biodegrade quickly to provide nutrients for
the lawn. Always mulch with your highest
engine (blade) speed as this will provide the
best recutting action of the blades.
• Avoid cutting your lawn when it is wet. Wet
grass tends to form dumps and interferes
with the mulching action. The best time to
mow your lawn is the early afternoon. At this
time the grass has dried and the newly cut
area will not be exposed to the direct sun.
adjuster setting higher than the front.
• Certain types of grass and grass conditions
may require that an area be mulched a
second time to completely hide the
clippings. When doing a second cut, mow
across or perpendicular to the first cut path.
• Changeyour cutting pattern from weekto
week. Mow north to south one week then
change to east to west the next week. This
will help prevent matting and graining of the
lawn.

IMPORTANT:Bladebolt is grade8 heat
treated.
TO SHARPEN BLADE
NOTE: Although multi--viscosity
oils
(5W30, 10W30 etc.) improve starting in
cold weather, these multi_viscosity oils
will result in increased oil consumption
when used above 32°F. Check your
engine oil level more frequently to avoid
possible engine damage from running low
on oil.
NOTE: We do not recommend sharpening
blade - but if you do, be sure the blade is
balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will cause
eventual damage to lawn mower or
engine.
• The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
• To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail exposed. Place center
hole of blade over the head of the nail.
If blade is balanced, it should remain in
a horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.

scan be dangerous. If you think the
engine-governed high speed needs
adjusting, contact your nearest authorized
service center, which has proper equipment and experience to make any
necessary adjustments.

or too slow, take your lawn mower to an
authorized service center for repair and

ENGINE
FUEL SYSTEM
IMPORTANT:
It is important to prevent gum
deposits from forming in essential fuel system
parts ,suchas carburetor, fuel filter, fuel hose,
or tank during storage. Also, experience
indicates that ak:ot_ blended fuels (called
gasehol or using ethanol or methanol) can
attract moisture which leads to separation and
formation of acids during storage. Acidic gas
can damage the fuel system of an engine
while in storage.
• Drain the fuel tank.
• Start the engine and let it run until the fuel
lines and carburetor are empty.
• Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable
alternative in minimizing the formation of fuel
gum deposits during storage. Add stabilizer to
gasoline in fuel tank or storage container.
Always follow the mix ratio found on stabilizer
container. Run engine at least 10 minutes
after adding stabilizer to allow the stabilizer to
reach the carburetor. Do not drain the gas
tank and carburetor if using fuel stabilizer.
ENGINE OIL
Drain oil (with engine warm) and replace with
clean engine oil. (See "ENGINE" in the
Maintenance section of this manual).
CYLINDER
• Remove spank plug.
• Pour one ounce (29 ml) of oil through spark
plug hole into cylinder.
• Pull starter handle slowly a few times to
distribute oil.
• Replace with new spark plug.
