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 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 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.

TO EMPTY GRASS CATCHER
Grass frame
• 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 whdn 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 top of slot in filler hole.
• Use 20 ozs. of oil.
For type and grade of oil to use, see "ENGINE" in Maintenance section of this manual.
6
• Pour oil slowly.
Do not over fill.
• Check oil level before each use.
Add oil if needed.
• Reinstall engine oil plug and tighten.
• 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. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quantities 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.

TO START ENGINE
• To starta coldengine, push primerfive(5)
timesbeforetryingto start. Use a firm push.
This step is not usuallynecessarywhen startingan enginewhich has already runfor
a few minutes.
• Holdoperatorpresence controlbar downto
the handleand pullstarter handlequickly.
Do not allow starter ropeto snapback.
• To stopengine, release operatorpresence
controlbar.
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 attempting 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 (push-
ing 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 indicates that alcohol blended fuels (called gesohol 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.
• Drain the fuel tank.
• Start the engine and let it run untilthe fuel
lines and carburetor are empty.
• Never use engine or carburetor cleaner
products in 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 during storage. 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 after adding stabilizer to allow the stabilizer to reach the carburetor.
Do not drain the gas tank and carburetor if using fuel stabilizer.
