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 and fill to the full
line on the dipstick.
NOTE: Allow oil to settle down into
engine for accurate dipstick reading.
• Engine holds 20 ozs. of oil. For type and
grade of oil to use, see "ENGINE" in
Maintenance 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.
ADD GASOUNE
NOTE: Before filling fuel tank, remove and
discard the debris plug that is insidethe tank.
• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of 87
octane. Do not mix oilwith gasoline.
Purchase fuel in quantities that can be
used within 30 days to assure fuel
freshness.
_.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, start the
engine and let it run until 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 fuel tank
or permanent damage may occur.
ACAUTION: 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 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. Ifyou do flood engine, wait a few
minutes before attempting to start and do not
repeat priming steps.

MOWlNGTIPS
• Under certain conditions, such as very tail
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.
• 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.
MULCHING MOWING TIPS
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 intothe grass and
not be noticed. A!so, the mulched grass will
biedegrade quickly to provide nuthents 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 iswet. Wet
grass tends to form clumps and interferes
with the mulching action. The best time to
mow your lawn isthe 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. Ifthe 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 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.

FUEL SYSTEM
IMPORTANT: It is important to prevent
_luUmdeposits from forming in essential
el system parts such as carburetor, 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
