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
upper limit mark on dipstick.
NOTE: Allow oil to settle down into
engine for accurate dipstick reading.
• Engine holds 18 1/2 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 the upper limit mark
on dipstick.
•To read proper level, insert the dipstick
into the tube and rest engine oil cap on
the tube. Do not thread the cap onto
the tube. Remove and read the oil
level.
• 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 GASOLINE
• 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.
_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.

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. 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.
9
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 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
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.
BEFORE EACH USE
• Check engine oil level.
• Check for loose fasteners.
LUBRICATION
Keep unit well lubricated (See "LUBRICA-
TION CHART").

ENGINE
LUBRICATION
Use only high quality detergent oil rated
with API service classification SF, SH or
SG. 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.
TO CHANGE ENGINE OIL
NOTE: Before tipping lawn mower to
drain oil, drain fuel tank by running
engine until fuel tank is empty.
• Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with spark plug.
• Remove engine oil cap; lay aside on a
clean surface.
• Tip lawn mower on its side as shown
and drain oil into a suitable container.
Rock lawn mower back and forth to
remove any oil trapped inside of
engine.
• Wipe off any spilled oil on lawn mower
and on side of engine.
• Fill engine with oil. Fill to the upper
limit mark on the dipstick. DO NOT
OVER FILL.
• To read proper level, insert the dipstick
into the tube and rest oil fill cap on the
tube. Do not thread the cap onto the
tube. Remove and read the oil level.

CARBURETOR
If your engine does not operate properly due
to suspected carburetor problems, take your
lawn mower to an authorized service center
for repair or adjustment.
IMPORTANT: Never tamper with the engine
govemor, which is factory set for proper
engine speed. Overspeeding the engine
above the factory high speed setting can be
dangerous• if you think the engine-govemed
high speed needs adjusting, contact your
nearest authorized service center, which has
proper equipment and experience to make
any necessary adjustments.
ENGINE SPEED
Your engine speed has been factory set. Do
not attempt to increase engine speed or it
may result in personal injury. If you believe
that the engine is running too fast or too slow,
take your lawn mower to an authorized
service center for repair and adjustment.
Immediately prepare your lawn mower for
storage at the end of the season or if the unit
will not be used for 30 days or more.
LAWN MOWER
When lawn mower is to be stored for a period
of time, clean it thoroughly, remove all dirt,
grease, leaves, etc. Store in a clean, dry area.
•Clean entire lawn mower (See "CLEAN-
ING" in the Maintenance section of this
manual).
• Lubricate as shown in the Maintenance
section of this manual•
• Be sure that all nuts, bolts, screws, and pins
are securely fastened. Inspect moving
parts for damage, breakage and wear.
Replace if necessary.
• Touch up all rusted or chipped paint
surfaces; sand lightly before painting.
HANDLE
You can fold your lawn mower handle for
storage.
• Squeeze the bottom ends of the lower
handle toward each other until the lower
handle clears the handle bracket, then
move handle forward.
•Loosen upper handle mounting bolts
enough to allow upper handle to be folded
back.

FUEL SYSTEM
IMPORTANT: It is important to prevent
gum deposits from forming in essential
fuel 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
dama_le 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
TROUBLESHOOTING CHART
PROBLEM CAUSE
