o Be sure mower islevel and area around oil

fill is clean.

= Remove engine oil cap w/dipstick and fill to

the full line on the dipstick.

o Use 20 ozs. of oil. Fortype and grade of oil

to use, see "ENGINE" in Customer

Responsibilities section of this manual.

= Pour oil slowly. Do not over fill

-Check oil level before each use. Add oil if

needed. Fil!to full line ondipstick.

° To read proper level, tighten engine oil cap

each time.

o Reinstall engine oilcap and tighten.

°Change the oil after every 25 hours of

operation or each season° You rnayneed

to change the oil more often under dusty,

dirty conditions.

ADD GASOLINE

oFillfuel tank_ Usefresh, clean, regular'

unleadedgasoline witha minimum of87

octane. Do not mix oilwith gasoline.

Purchase fuel in quantities that can be used

within 30 days to assure fuel freshness_

IMPORTANT: When operating in

temperatures below 32°F(0°C), use fresh,

clean winter grade gasoline to help insure

good cold weather starting.

WARNING: Experience indicates that alcohol

blended fuels (called gasohol or using ethanol

or rnethanol) 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:

Drainthe gas tank, start the engine and let it

run untilthe 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.

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 a coldengine, push primerthree

(3) timesbefore tryingtostart. Use a firm

push_ This step is not usually necessary

when starting an engine which has already

runfor a few minutes,

o Hold operator presence control bar down to

the handle and pull starter handle quickly.

Do not allow starter rope to snap back.

o To stop engine, release operator presence

control bar.

NOTE: In cooler weather it may be

necessary to repeat priming steps. In

warmew: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

o 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 clipping&

o For extremely heavy cutting, reduce the

width of cut and raise the rear of the lawn

mower housing one (1) wheel adjuster

setting higher than the front for better

discharge of grass.

° For better grass bagging and most cutting

conditions, the engine speed should be set

in the fast position°

o When using a rear discharge lawn mower in

moist, heavy grass, clumps of cut grass

may not enter the grass catcher. Reduce

ground speed (pushing speed) and/or run

the lawn mower over the area a second

time_

o If a trail of grass clippings is lefton the right

side of a rear discharge lawn mower, mow

in a clockwise direction with a small overlap

to collect the clippings on the next pass.

° Keep top of engine around starter clear and

clean of grass clippings and chaff° This will

helpengine air flow and extend engine life.

• 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 catchers off with water

and let dry before using.

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

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 fawn is the early afternoon. 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°

tf 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.

o 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 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. Max 1/3

GENERAL RECOMMENDATIONS

The warranty on this lawn mower does not

cover items that have been subjected to

operator abuse or negligence. To receive

full value from the warranty, operator must

maintain mower as instructed in this

manual.

Some adjustments will need to be made

periodically to properly maintain your unit.

All adjustments in the Service and

Adjustments section of this manual should

be checked at least once each season.

• Once a year, replace the spark plug,

replace air filter element and check

blade for wear. A new spark plug and

clean/new air filter element assures

proper air-fuel mixture and helps your

engine run better and last longer.

• Follow the maintenance schedule in this

manual.

BEFORE EACH USE

•Check engine oil level,

e Check for loose fasteners.

LUBRICATION

Keep unit well lubricated (See "LUBRICA-

TION CHART").
