theengine. Engine holds 20 oz. of oil.
For type and grade of oil to use, see
"ENGINE" in Maintenance section of this
manual.
1. Be sure lawnmower is level and area
around oil fill is clean.
2. Remove engine oil cap and fill to the
full line on the dipstick. Pour oil slowly.
Do not over fill.
NOTE: Allow oil to settle down into engine
for accurate reading. To read proper level,
tighten engine oil cap, then remove it to
read the dipstick.
3. Reinstall engine oil cap and tighten.
•Check oil level before each use. Add
oil if needed. Fill to full line on dipstick.
• 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
NOTE: Before filling fuel tank, remove
and discard the debris plug that is inside
the tank.
•Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. Do not mix oil with gaso-
line. 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 dudng storage. Acidic
gas can damage the fuel system of an
enginewhile 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.
_1_CAUTION: Fill to bottom of gas tank

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 ovedoading 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.
•For side discharge lawn mowers,
cutting in acounter-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
flint cuts in a clockwise direction.
•Pores in cloth grass catchers can
"become filled with dirt and dust with
use end 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 MOWINGTIPS
IMPORTANT: For best performance,
keep mower housing free of built-up
grass and trash. See "Cleaning" in
MAINTENANCE section of this manua
•The special mulching blade will reel
the grass clippings many times and
reduce them in size so that as they f
onto the lawn they will disperse into
grass and not be noticed. Also, the
mulched grass will biodegrade quic
to provide nutdents for the lawn.
Always mulch with your highest eng
(blade) speed as this will provide th,
best recurring action of the blades.
•Avoid cutting your lawn when it is w_
Wet grass tends to form clumps and
interferes with the mulching action, "
best time to mow your lawn is the e_
afternoon. At this time the grass has
dried and the newly cut area will no1
exposed to the direct sun.
•For best results, adjust the lawn mo'
cutting height so that the lawn mowq
cuts off only the top one-third of the
grass blades. If the lawn is overgrov
will be necessary to raise the height
cut to reduce pushing effort and to kq
from overloading the engine and
leaving clumps of mulched grass. F¢
extremely heavy mulching, reduce y
width of cut by overlapping previous
cut path and mow slowly.
•Certain types of grass and grass
conditions may require that an area
mulched asecond time to completel
hide the clippings. When doing a
second cut, mow across or peq3end;
lar to the first cut path.
•Change your cutting pattem from w(
to week. Mow north to south one we
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 adiustments 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,
clean or 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
1. Check engine oil level.
2. Check for loose fasteners.
LUBRICATION
Keep unitwell lubricated (Sea "LUBRI-
CATION CHART").

NOTE: Although multi-viscosity oils
(5W30, 10W30 Otc.) 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,

CARBURETOR
Your carburetor has a non-adjustable
fixed main jet for mixture control. If your
engine does not operate propedy due to
suspected carburetor problems, take your
lawn mower to an authorized service
center for repair and/or adjustment.
IMPORTANT: Never tamper with the
engine governor, 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-governed high speed needs
adjusting, contact your nearest autho-
rized service center, which has proper
equipment and experience to make any
necessary adjustments.
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,
1. Clean entire lawn mower (See
"CLEANING" in the Maintenance
section of this manual).
2. Lubdcate as shown in the Mainte-
nance section of this manual.
3. Be sure that all nuts, bolts, screws,
and pins are securely fastened.
Inspect moving parts for damage,
breakage and wear. Replace if
necessary.
4. Touch up all rusted or chipped paint
surfaces; sand lightly before painting.

FUELSYSTEM
IMPORTANT: It is important to prevent
gum deposits from forming in essential
fuel system parts such as carburetor, fuel
filter, fuel hose, or tank dudng 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.
1. Drain the fuel tank.
2. 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
1. Remove spark plug.
2. Pour one ounce (29 ml) of oil through
spark plug hole into cylinder.
3. Pull starter handle slowly a few times
to distribute oil.
4. 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 it to give protection from dust and
dirt.
•Cover your unit with a suitable protec-
tive cover that does not retain mois-
ture. Do not use plastic. Plastic cannot
breathe which allows condensation to
form and will cause your unit to rust.
IMPORTANT: Never cover mower while
engone and exhaust areas are still warm.
ACAUTION: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.
