MOWING TIPS
•• Under certain conditions, such as ver_
tall grass, it may be necessary to raise
the height of cut to reduce pushing
effort and to keep from overloading thq
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 tt
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.
• For side discharge lawn mowers,
cutting in a counter-clockwise directio
starting at the outside of the area to b_
cut, spreads grass clippingsmore
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 gras
To prevent this, regularly hose catche
off with water and let dry before using
• Keep top of engine around starter cle
and clean of grass clippings and chaf
This will help engine air flow and
extend engine life.

control chemicals which can harm rubber.
• Avoid stumps, stones, deep ruts,sharp
objects and other hazards that may cause
tim damage.
BLADE CARE
For best results, mower blade must be
kept sharp. Replace bent or damaged
blades.
TO REMOVE BLADE
• Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with spark plug.
• Turn lawn mower on its side. Make sure
air filter and carburetor are up.
• Use a wood block between blade and
mower housing to prevent blade from
turning when removing blade bolt.
• Protect your hands with gloves and/or
wrap blade with heavy cloth.
• Remove blade bolt by turning counter-
clockwise.
• Remove blade and attaching hardware
(bolt, lockwasher and hardened
washer).
NOTE: Remove the blade adapter and
check the key insidehub of blade adapter.
The key must be in good conditionto work
properly. Replace adapter ifdamaged.
TO REPLACE BLADE
• Position the blade adapter on the engine
crankshaft. Be sure key inadapter and
crankshaft keyway are aligned.
• Position blade on the blade adapter
aligningthe two (2) holes in the blade
with the raised lugs on the adapter.
• Be sure the trailing edge of blade
(opposite sharp edge) is up toward the
engine.
• Install the blade boltwith the lock
washer and hardened washer intoblade
adapter and crankshaft.
• Use block of wood between blade and
lawn mower housing and tighten the
blade bolt,turning clockwise.
• The recommended tighteningtorque is
35-40 ft. Ibs.
11
IMPORTANT: Blade bolt is grade 8 heat
treated.
TO SHARPEN BLADE
NOTE: We do not recommend sharpening
blade - but ifyou do, be sure the blade is
balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will cause
eventual damage to lawn mower or
engine.
• The blade can be sharpened with a file
or on a grindingwheel. Do not attempt
to sharpen while on the mower.
• To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail exposed. Place center
hole of blade over the head of the nail.
If blade is balanced, it should remain in
a horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.

• If lubricant is required, use only Texaco
Starplex Premium Grease, part no.
750369. Do not substitute.
DRIVE WHEELS
Check front drive wheels each time before
you mow to be sure they move freely.
The wheels not turningfreely means trash,
grass cuttings, etc. are in the drive wheel
area and must be cleaned to free drive
wheels.
If necessary to clean the drive wheels,

FUELSYSTEM
IMPORTANT: It isimportant to 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
gasohol or using ethanol or methanol) can
attract moisture which leads to separ'_on and
formation of acids during storage. Ac'_licgas
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
aitemative 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.
ENGINEOIL
Drain oil (with engine warm) and replace with
clean engine oil. (See "ENGINE" in the
Maintenance section of this manual).
CYUNDER
• Removespa p g.
• Pour one ounce(29 mi) ofoilthrough spark
plughole intocylinder.
• Pullstarterhandleslowlya few timesto

• Replacewith new spark plug.
BA'I-rERY
Disconnect the battery from the engine
connector and charge battery 48 hours.
