BEFORE STARTING ENGINE

OIL

Your lawn mower isshipped without oil in the

engine.

• Be sure mower is level and area around oil

fill is 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. 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.

GAS

• 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.

A0_WARNING: Expe.dence indicates that

alcohol blended nJels (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 gas

tank, start the engine and let it run until the

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 the fuel tank or

permanent damage may occur.

TO START ENGINE

•To start a cold engine, push primer three

(3) times before trying to start. Use a firm

push. This step is net 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 itmay be necessary

to repeat priming steps. In warmer weather

over priming may cause flooding and engine

will net start. If you do flood engine wait afew

minutes before attempting to start and do not

repeat pdming steps.

MOWING TIPS

•For most cutting conditions and better

bagging performance, the engine speed

shouldbe setinthefastposition.

• Under certainconditions,such as when

mowing very tall grass, raise, the mower

height on the first cut to reduce pushing

effort, to avoid overheating the engine, and

to avoid leaving clumps of grass clippings.

Make the second cut to the desired height.

For extremely heavy cutting, reduce the

width of cut.

• Pores in cloth grass catchers can become

filled with dirt and dust with use and the

catcher will collect less grass. To prevent

this, regularly hose catcher off with water

and let dry before use.

MULCHING MOWING TIPS

IMPORTANT: For best performance, keep

mower housing free of built-up grass and

trash. Sea "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 fail 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

SLIn.

• 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 itwill be

necessary to raise the height of cut to

reduce pushing effort and to keep from

overloading the engine and leaving

dumps 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

across or perpendicular to the first cut path.

• Change your cutting pattem from week to

weak. Mow north to south one week then

change to east to west the next weak. This

will help prevent matting and graining of

the lawn.
