GAS

,, 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.

a_coWARNING: Experience indicates that

hot blended fuels (called gasohot 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 fuet 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.

BEFORE STARTING ENGINE

OIL

in the engine.

• Be sure mower is level and area

around oil fill is clean.

•Remove engine oil cap and fill to the

upper limit mark on dipstick.

• Engine holds 18 1/2 ozs. of oil. For

type and grade of oil to use, see

"ENGINE" in Maintenance section of

this manual.

o Pour oil slowly. Do not over fill.

•Check oil level before each use. Add

oil if needed. Fill to the upper limit mark

on dipstick.

•To read proper level, insert the dipstick

into the tube and rest engine oil cap on

the tube. Do pot thread the cap onto

the tube. Remove and read the oil

level.

o Reinstall engine oil cap and tighten.

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 runthe 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

fitled 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 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 w?[hyour highest

engine (blade) speed as this will provide

the best recutting action of the blades.

°Avoid cutting your lawn when it iswet. 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 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. 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,

mow slowly and raise the rear of the lawn

mower one wheel adjuster setting higher

than the front.

•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

weeP,.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.
