BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil in

the engine.

• Be sure mower is level and area

around oil fill is clean.

• Remove engine oil cap and fill to the

full line on the dipstick.

NOTE: Allow oil to settle down into

engine for accurate 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

•Fill fuel tank. Use fresh, 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

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 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.

_I,CAUTION: Fillto bottom of gas tank

filler neck. Do not overfill. Wipe off any

spilled oil or fuel. Do not store, spill or u,_

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.

• Move throttle control lever to fast

position.

• 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 necessaq

to repeat priming steps. In warmer weather

over priming may cause flooding and engine

will not start. If you do flood engine wait a fen

minutes before attempting to start and do not

repeat priming steps.

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 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-up grass and

trash. See "Cleaning" in MAINTENANCE

section of this manual.

•The special mulching blade will recut the

gross 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 iswet. Wet

grass tends to form clumps and interferes

with the mulching action. The best time to

mow your lawn is the early aftemson. 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 that the lawn mower cuts

off only the top one-third of the grass

blades. Ifthe 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 conditions

may require that an area be mulched a

second time to completely hide the

clippings. When doing a second cut, mow

acmas or perpendicular to the first cutpath.

•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.
