BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped withoutoil in the
engine.

• Be sure mower is level and area around oil

fill isclean.

• Remove engine oilcap and fillto the full

line on the dipstick.

NOTE: Allow oil to settle down into

engine for accurate dipstick reading.

• Engine holds 20 ozs. of oil. Fortype and

grade ofoilto use, see "ENGINE" in
Maintenance section of this manual.

• Pour oilslowly. 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.

6

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.

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 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. 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. 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 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
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.

7

MULCHING MOWING TIPS
IMPORTANT: For best performance, keep

mower housing free of built-upgrass and
trash. 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 aftemoon. 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 thatthe 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

by overlapping previously cut path and

mow slowly.

Certain types of grass and grass condi-

tions 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 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.

ENGINE
FUEL SYSTEM

IMPORTANT: It is importantto prevent gum
depositsfrom 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 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 stabilizeris an acceptable

alternative in minimizingthe formation of fuel

gum deposits during storage. Add stabilizer
to gasoline in fuel tank or storage container.
Always follow the mix ratiofound 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 ifusing fuel stabilizer.

ENGINEOIL
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.

14

OTHER

• Do not store gasoline from one season to

another.

• Replace your gasoline can if your can
startsto rust. Rust and/or dirtin your
gasoline will cause problems.

• If possible, store your unitindoors and
cover it to give protectionfrom dust and dirt.

• Cover your unitwith 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.
