HOWTO USEYOUR LAWNMOWER

ENGINE SPEED CONTROL

The engine speed was set at the factory

for optimum performance. Speed is not

adjustable.

ENGINE ZONE CONTROL

_CAUTION: Federal regulations require

an engine control to be installed on this

lawn mower in order to minimize the risk

of blade contact injury. Do not under any

circumstances attempt to defeat the

function of the operator control. The blade

turns when the engine is running.

•Your lawn mower is equipped with an

operator presence control bar which

requires the operator to be positioned

behind the lawn mower handle to start and

operate the lawn mower.

TO ADJUST cUTrlNG HEIGHT

•Raise wheels for low cut and lower wheels

forhkjhcuL

•Adjust cutting height to suit your require-

merits. Medium positionis best for most

lawns.

•To change cutting height, squeeze adjuster

lever toward wheel. Move wheel up or

down to suit your requirements. Be sure all

wheels are in the same setting.

NOTE: Adjuster is propedy positioned

when plate tab inserts into hole in lever.

Also, 9-position adjusters (if so equipped)

allow lever to be positioned between the

plate tabs.

ADD GASOUNE MOWING TIPS

•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.

AWARNING: 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 five

(5) 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.

Engine oilcap Gasoline filler

cap

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.

• To check blade balance, drive a nail

into a beam or wall. Leave about one

inch of the straight nail exposed. Place

center hole of blade over the head of

the nail. If blade is balanced, it should

remain in a horizontal position. If either

end of the blade moves downward,

sharpen the heavy end until the blade

(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 oilafter every 25 hours of

operation orat least once a year if the lawn

mower is not used for 25 hoursin one year.

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

the proper engine speed. Overspeeding

the engine above the factory high speed

scan be dangerous. If you think the

engine-govemed high speed needs

adjusting, contact your nearest authorized

service center, which has proper equip-

ment and experience to make any

necessary adjustments.

FUELSYSTEM

IMPORTANT: it is importantto prevent gum

deposits from forming in essential fuel system

pads such as carburetor,fuel filter,fuel hose,

or tank during storage. Also, experience

indP..atesthat alcohol blended fuels (called

gasohol or using ethanol or methanol) can

attract moisture wi';tch leads to separatien

and formation of acids during storage. Acidic

gas can damage the fuel system ot an

engine while in storage.

•Drainthefueltank.

•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 fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable

altemative in minimizing the formation of fuel

gum deposits during storage. Add stabirr_er

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 alow the _er to

reach the carburetor. Do not drain the gas
