BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped withoutoil in the

engine.

•Be sure mower is level and area around oil

fillis clean.

•Remove engine oilcap and fillto the full

lineon the dipstick.

NOTE: Allow oil to settle down into

engine for accurate dipstick reading.

•Engine holds 20 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 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.

ADD GASOLINE

•Fillfuel tank. Use frosh, clean, regular

unleaded gasoline with a minimum of 87

octane. (Use of leaded gasoline will

increase carbon and lead oxide deposits

and reduce valve life). Do not mix oil with

gasoline. Purchase fuel in quan_les that

can be used within 30 days to assure fuel

freshness.

_WpAoRNING: E.xp#.rieneaindicatesthat

I 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 of30 days or longer. Drain the gas

tank, startthe engine and let it run untilthe

fuel lines and carburetor are empty. Use fresh

fuel next season. Sea Storage Instructionsfor

additionalinformation. Never use engine or

carburetor cleaner products in the fuel tank or

permanent damage may occur.

TO START ENGINE

•To start a cold engine, push primer five (5)

times before tryingto 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 pullstarter 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.

• 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-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 ontothe

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 iswet. 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 willnot be exposed to the direct

sun.

•For best results,adjustthe lawn mower

cuttingheight so that the lawn mower cuts

off only the top one-thirdof the grass

blades. If the lawn isovergrown it willbe

necessary to raise the height of cut to

reduce pushing effortand to keep from

overloading the engine and leaving

clumps of mulched grass. For extremely

heavy mulching, reduce your width ofcut

by overlapping previously cut path and

mowslowly.

•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 perpendicular to the firstcut path.

•Change your cuttingpattem from week to

week. Mow northto south one week then

change to east to west the nextweek. This

will help prevent matting and grainingof

the lawn.
