BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil in the

engine.

o Be sure mower is level and area around oil

fillis clean.

• Remove engine oil cap w/dipstick and fill to

the full line on the dipstick.

° Use 20 ozs. of oil. For type and grade of oil

touse, see "ENGINE_' inCustomer

Responsibilities section of this manual.

o Pour oil slowly. Do not over' fill.

= Check oil level before each use. Add oil if

needed. FilI to full line on dipstick,

o To read proper level, tighten engine oil cap

each time,

o Reinstall engine oil cap and tighten.

o Change the oil after every 25 hours of

operation or each season. You may need to

conditions,

GAS

• Fill fuel tank. Use fresh, clean, regular

unteaded gasoline with a minimum of 87

octane. Do not mix oil with gasoline.

Purchase fuel in quantities thatcan be used

within 30 days to assure fuel freshness.

IMPORTANT: When operating in

temperaturesbelow 32°F(0°C), use fresh,

clean winter grade gasofine to help insure

good cold weather starting.

WARNING: Experience indicatesthat alcohol

blended fuels (called gasohol or using ethanol

or methano0 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 additiona_ information,

Never use engine or carburetor' cleaner

products in the fuel tank or permanent

damage may occur:

CAUTION: Fill to bottom of gas tank filter

neck, Do not overfill° V'_peoff any spilled oil or

fuel Do not store, spill or use gasoline near an

open flame_

TO START ENGINE

over priming may cause floodin.g and engine

will not start. If you do flood engine, wait a few

minutes before attempting to start and do not

repeat priming steps, Engine oil cap w!

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 overloadingthe engine and

!eaving clumps of grass clippings.

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°

° When using a rear discharge lawn mower in

moist, heaw/grass, clumps of cut grass

may not enter the grass catchen 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 left on 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 ofengine around starter clear and

clean of grass clippings and chaff..This will

help engine 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.

Max,, 1/3

MULCHING MOWING TIPS

IMPORTANT: Forbest 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 wil! 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 dded and the newly cut

area will not be exposed to the direct sun.

o For best results, adjust the lawn mower

cutting height so that the lawn mower cuts

off only the top one4hird 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 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

across or perpendicular to the first cut path.,

o 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.
