engine, a small amount of smoke may be

present dudng the initial use of the

product and should be considered

normal.

1. Turn fuel valve to ON position.

can be used within30 days to assure

fuel freshness.

alcohol blended fuels (called gasohol or

using ethanol or methanol) can attract

moisture which leads to separation and

formation of acids dudng storage. Acidic

gas can damage the fuel systemof an

engine while in storage. To avoid engine

•MOWlNGTIPS

•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

cuttingconditions, 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 catchem willcollect less grass.

To prevent this, regulady 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 MOWINGTIPS

IMPORTANT: Forbest performance,

keep mower housing free of built-up

grass and trash. See =CLEANING" in the

Maintenance section of this manual.

•The special mulching blade will recut

the grass clippingsmany times and

reduce them in size so that as they fall

onto the lawn they will disperse intothe

grass and notbe noticed. Also, the

mulched grass will biodegrade quickly

to provide nutrientsfor the lawn.

Always mulchwith your highest engine

(blade) speed as this will provide the

best recuttlng action of the blades.

•Avoid cuttingyour lawn when it iswet.

Wet grass tends to formclumps and

interferes with the mulching action.

The best time to mow your lawn is the

eady aftemcon. At thistime the grass

has dded and the newly cut area will

not be exposed to the direct sun.

• For best results, adjust the lawn mower

cuttingheight 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 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

conditionsmay require that an area be

mulched a second time to completely

hide the clippings. When doing a

second cut, mow across or perpendicu-

larto the first cut path.

•Change your cutting paffem from weak

to week. Mow northto south one week

then change to east to west the next

week. This will help prevent matting

and graining of the lawn•
