HOW TO USE YOUR LAWN MOWER

ENGINE SPEED CONTROL

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 dsk of blade contact injury. Do not under any circumstances attempt to defeat the function of the operator control. The blade tums 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 requirements, Be sure all wheels are in the same setting.

NOTE: Adjuster is properly positioned when plate tab inserts into hole in lever.

Also, 9-position adjusters (if so equipped) allow lever to be positioned between the plate tabs.

Lower wheels for high cut

Raise wheels for low cut

Formed tabs

Grass frame

TO EMPTY GRASS CATCHER

To remove grass catcher, release operator presence control bar to stop engine,

Lift up rear door and remove the grass catcher by the handle.

NOTE: Do not drag the bag when emptying; it will cause unnecessary wear.

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 full line on the dipstick.

Use 20 ozs. of oil. For type and grade

of oil to use. see =ENGINE" in Mainte- nance section of this manual.

Pour oil slowly. Do not over fill.

Check oil level before each use. Add oil

if needed.

Fill to full line on dipstick.

To read proper level, tighten engine oil plug each time.

Reinstall engine oil plug and tighten.

Change the oil after every 25 hours of operation or each season.

You may need tochange the oil more often under dusty, dirty conditions.

GAS

Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane.

(Use of leaded gasoline will

increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline.

Purchase fuel in quanti- ties that can be used within 30 days to

assure fuel freshness.

WARNING: Experience indicates that alcohol blended fuels (called gasohol 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 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 additional information.

Never use engine

or carburetor cleaner products in the fuel tank or permanent damage may occur.

Gasoline filler cap

Engine oil

TO START ENGINE

To start a cold engine, push primer five (5)

times before trying to start. Use a firm push.

This step is not usually neeessan/when

starting an engine which has already run for

a few minutes.

• Hold operator presence controlbar down to the handle and pull starter handle quickly.

Do not allow starter rope to snap back.

To stop engine, release operator presence control bar.

NOTE: In cooler weather it may be necessary

to repeat priming steps. In warmer weather over priming may cause flooding and engine

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

minutes before attern_ng to start and do not

repeat priming steps.

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 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 cutting conditions, the engine speed

should be set in the fast position.

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.

• If a trail of clippings is left on the right side of a rear discharge mower, mow in a clockwise direction with a small overlap to collect the clippings on the next pass.

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.

FUEL SYSTEM

IMPORTANT: It is importantto prevent gum deposits from forming in essential fuel system parts such as carburetor,fuel filter,fuel hose,

or tank during storage. Also, experience

incr_atesthat alcohol blended fuels (called gasohol or using ethanol or methanol) can

attract moisture which leads to separation and

formation of acids during storage. Ac_bc gas

can damage the fuel system of an engine while in storage.

Drain the fuel tank.

Start the engine and let it run untilthe fuel

linesand carburetor are empty.

Never use engine or carburetor cleaner productsin the fuel tank or permanent

damage may occur.

Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits duringstorage. Add stabilizer to gasoline in fuel tank or storage container.

Always follow the mix ratio found on stabilizer container.

Run engine at least 10 minutes
