•Lift door upward on it's hinge until the
deflector frame can be hooked over the
door mounting bracket as shown.
•Release the door to rest against
deflector frame.
•To return to mulching operation, reverse
the above steps and be sure door is in
locked position.
BEFORE STARTING ENGINE OIL
Your lawn mower is shipped without oil in
the engine.
•Be sure mower is level and area around
oil fill is clean.
•Remove engine oil cap w/dipstick and fill
to the full line on the dipstick.
•Use 20 ozs. of oil. For type and grade
of oilto use, see "ENGINE" in Mainte-
nance section of this manual.
•Pour oil slowly. Do not over fill.
•Check oil level before each use. Add oil
if needed. Fill to full line on dipstick.
•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
• Fillfueltank. Usefresh,clean,regular
unleadedgasolinewithaminimumof87
octane.(Useof leaded gasoline will
increase carbon and lead oxide deposits
and reduce valve life). Do not mix oil
with gasoline. Purchase fuel in quanti-
ties that can be used within 30 days to
assure fuel freshness.
IMPORTANT: WHEN OPERATING IN
TEMPERATURES BELOW 32°F(0°C), use
fresh, clean winter grade gasoline to help
insure good cold weather starting.
WARNING: Expedence 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 fue_ 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.
CAUTION: Fill to bottom of gas tank filler
neck. Do not overfill. Wipe off any spilled
oil or fuel. Do not store, spill or use
gasoline near an open flame.

TO START ENGINE
• To start a cold engine, push primer five
(5) 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 pdming steps. In
warmer weather over pdming 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.
MOWING TIPS
•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.
•For extremely heavy cutting, reduce the
width of cut by overlapping previously
cut path and mow slowly.
•For side discharge lawn mowers, cutting
in a counter-clockwise direction, starting
at the outside of the area to be cut,
spreads grass clippings more evenly and
puts less load on the engine. To keep
clippings off of walkways, flower beds,
etc., make the first cuts in a clockwise
direction.
• 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 oft
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.
MULCHING MOWING TIPS
7
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 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, mow slowly and raise the rear of the
lawn mower one wheel 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 perpendicu-
lar to the first cut path.
•Change your cuffing pattem 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.

•To check blade balance, drive anail 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.
GRASS CATCHER
•The grass catcher may be hosed with
water, but must be dry when used.
•Check your grass catcher often for
damage or deterioration. Through
normal use it will wear. If catcher needs
replacing, replace only with a manufac-
turer approved replacement catcher.
Give the lawn mower model number
when ordering.
ENGINE
LUBRICATION
Use only high quality detergent oil rated
with API service classification SF, SG, or
SH. Select the oil's SAE viscosity grade
according to your expected operating
temperature.
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.
Change the oil after every 25 hours of
operation or at least once a year if the
lawn mower is not used for 25 hours in one
year.
Check the crankcase oil level before
starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.

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 carbure-
tor. 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 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 new 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 itto 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.
