BEFORE STARTING ENGINE
ADD OIL
Your lawnmower is shipped without oil in
the engine. 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 road proper level,
tightenengine oilcap, then remove itto
read the dipstick.
3, Reinstall engine oil cap and tighten.
• Check oil level before each use. Add
oil if needed. Fillto full line on dipstick.
• Change the oil after every 25 hours of
operationor 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 gaso-
line. Purchase fuel in quantities that
can be used within 30 days to assure
fuel freshness.
A,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 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. Donot overfill. Wipeoffany
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.

MOWINGTIPS
• 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 groundspeed 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
cuttingconditions,the engine speed
should be set in the fast position.
• When using a rear discharge lawn
mower in moist,heavy grass, clumps of
cut grassmay 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 clippingsis left on the right
side of a rear discharge mower, mow in
a clockwise directionwith a small
overlap to collect the clippingson the
next pass.
• Pores in cloth grass catchers can
become filledwith dirtand dustwith use
and catchers willcollect less grass. To
prevent this, ragulady hose catcher off
with water and let dry before using.
• Keep fop 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 the
Maintenance section of this manual.

FUEL SYSTEM
IMPORTANT: It isimportantto prevent
gum deposits from forming in essential
fuel system parts suchas 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.
1. Drain the fuel tank.
2, Start the engine and let it run untilthe
fuel lines and carburetor are empty.
• Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
• Use freshfuel 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 attar 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 rep!,ace
with clean engine oil. (See ENGINE in
the Maintenance section of this manual),
15
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 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 stodng in any enclosure.
