TO START ENGINE
• To start a cold engine, push primer
three (3) times before trying to start.
Use a firm push. This step is not
usually necessary when starting an
engine which has already run for a few
minutes.
• Hold operator presence control bar
down to the handle and pull starter
handle quickly. Do not allow starter
rope to snap back.
• To stop engine, release operator
presence control bar.
NOTE: In cooler weather it may be
necessary to repeat priming steps. In
warmer weather over priming may cause
flooding and engine will not start. If you
do flood engine, wait a few minutes
before attempting to start and do not
repeat priming steps.
• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane.
Do not mix oil with gasoline. Purchase fuel in quantities that
can be used within 30 days to assure
fuel freshness.
AWARNING:
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 gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
next season.
See Storage Instructions
for additional information.
Never use
engine or carburetor cleaner products in
the fuel tank or permanent damage may
occur.

MOWING TIPS
MULCHING
• 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.
• 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
overlap to collect the clippings on the
next pass.
• Pores in cloth grass catchers can
become filled with dirt and dust with use
and catchers will collect less grass. To
prevent this, regularly hose catcher off
with water and let dry before using.
• Keep top of engine around starter clear
and clean of grass clippings and chaff.
This will help engine air flow and
extend engine life.
IMPORTANT:
For best performance,
keep mower housing free of built-up
grass and trash. See "Cleaning" in
Maintenance section of this manual.
MOWING TIPS
• 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 clumps 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.
• For best results, adjust the lawn
mower cutting height so that the lawn
mower cuts 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 by overlapping previously cut path and mow
slowly.
• 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.
• Change your cutting pattern from week
to 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.

GENERAL
RECOMMENDATIONS
LUBRICATION
The warranty on this lawn mower does not
cover items that have been subjected to
operator abuse or negligence.
To receive
full value from the warranty, operator must
maintain mower as instructed in this
manual.
Some adjustments will need to be made
periodically to properly maintain your unit.
All adjustments in the Service and
Adjustments section of this manual should
be checked at least once each season.
• Once a year, replace the spark plug,
replace air filter element and check
blade for wear. A new spark plug and
clean/new air filter element assures
proper air-fuel mixture and helps your
engine run better and last longer.
• Follow the maintenance schedule in this
manual.

FUEL SYSTEM
IMPORTANT: It is importantto prevent gum
deposits from forming in essential fuel system
parts such as carburetor, f fuel filter, fuel hose
or tank during storage. Also, 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.
• 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.

ENGINEOIL
Drain oil (with engine warm) and replace with
clean engine oil. (See "ENGINE" in the
Maintenance section of this manual).
CYLINDER
• Remove spark 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 nev_ spark plug.
OTHER
• Do not store gasoline from one season to
another.
• Replace your gasoline can if your can
starts to rust. Rust and/or dirt in your
gasoline will cause problems.
• If possible, store your unit indoors and
cover it to give protection from dust and dirt.
• Cover your unit with a suitable protective
cover that does not retain moisture. Do
not use plastic. Plastic cannot breathe
which allows condensation to form and will
cause your unit to rust.
IMPORTANT: Never cover mower while
engine and exhaust areas are still warm.
_CAUTION:
Never store the lawn
mower with gasoline in the tank inside a
building where fumes may reach an open
flame or spark. Allow the engine to cool
before storing in any enclosure.
