HOW TO USE YOUR LAWN MOWER

ENGINE SPEED

The engine speed was set at the factory

for optimum performance, Speed is not

adjustable.

ENGINE ZONE CONTROL

CAUTION; Federal regulations require an

engine control to be installed on this lawn

mower in order to minimize the risk of

blade contact injury. Do not under any

circumstances attempt to defeat the

function of the operator control° The blade

turns when the engine is running,

°Your lawn mower is equipped with an

operator presence control bar which

requires the operator to be positioned

behind the lawn mower handle to start

and operate the lawn mower.

TO ADJUST CUTTING HEIGHT

°Raise wheels for low cut and lower

wheels for high cut.

° Adjust cutting height to suit your

requirements. Medium position is best

for most lawns.

•To change cutting height, squeeze

adjuster lever toward wheel. Move

wheel up or down to suit your require-

ments. Be sure all wheels are in the

same setting.

NOTE: Adjuster is properly positioned

when plate tab inserts between tabs in

lever. Also, 9-position adjusters (if so

equipped) allow lever to be positioned

between the plate tabs.

Raise wheels for low cut _ Lever'

_ ___ _atetab!I

Lower wheels for

high cut

CAUTION: Do not run your lawn mower

without discharge guard, approved grass

catcher in place.

BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil in

the engine.

= Be sure mower is level and area around

oil fill is clean.

,, Remove engine oil plug and fill to the

top of slot in filler hole.

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

of oil to use, see "ENGINE" in Customer

Responsibilities section of this manual.

o Pour oil slowly. Do not over fill.

o Check oil level before each use. Add oil

if needed.

o Reinstall engine oil plug and tighten.

o 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. Do not mix oil with gasoline.

Purchase fuel in quantities that can be

used within 30 days to assure fuel

freshness. Gasoline filler cap

Oil fillerplug

TO START ENGINE

oTo start a cold engine, push primer five

(5) times before trying to start. Use a

firm push. This step is not 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.

o To STOP engine, release operator

presence control bar.

NOTE:Incoolerweatherit may be o

necessary to repeat priming steps_ In

warmer weather over priming may cause

flooding and engine will not start. If you do o

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 clippings.

• 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

For side discharge lawn mowers, cutting

in a counter-clockwise direction, starting

at the outside of the area to be cut,

spreads grass clippings more evenly

and puts less load on the engine. To

keep clippings off of walkways, flower

beds, etc. make the first cuts in a

clockwise direction

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 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.
