BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped withoutoil in the

engine.

•Be sum mower is level and area around oil

fillis clean.

•Remove engine oil cap 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. 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. Fillto full lineon 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 conddions.

ADDGASOUNE

•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.

_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.

_CAUTION: 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 acold engine, push primer three

(3) times before tryingto start. Use a firm

push. This step is not usuaity necessary

when starting an engine which has already

run for afew 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.

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. Clean UNDERSIDE OF MOWER

HOUSING after each use. See "Cleaning"

in MAINTENANCE section of this manual.

The special mulching blade will mcut

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

afternoon. At this time the grass has

dried and the newly cut area wilt 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. 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 ot 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 perpendicu-

tar to the first cut path.

Change your cutting pattern 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.
