MULCHING MOWlNGTIPS
• Under certain concilk_ such as very tail
grass, it may be nenessery to raise the
height of cut to reduce pushing effort and to
keap from overloading the engine and
leaving clumps of grass clipp_s. It may
aise be necessary to reduce ground speed
and/or run the lawn mower over the area a
second time.
• For extremely heavy cutting,reduce the
IMPORTANT:. For best performance, keep
n_wer housing free of buUt-upgrass 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 cl'_opingsmany times and reduce
them in size so that as they fail onto the
lawn they will dispeme into the grass and
not be noticed.Also, the mulched grass will
biodegrade quickly to provide nutrientsfor
the lawn. Always mulch with your highest
engine (blade) speed as this will provide
the best re_fting actien of the I_des.
• Avoid cuttingyour lawn when itis weL Wet
grass tends to form dumps and inte=feres
wi_ the mulching ac'don.The best time to
mow your lawn is the early afternoon. At
this time the grass has dried and the newiy
cut area will net be exposed to the direct
sun.
• For best results, adjust the lawn mower
cutling 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 gra,ss.For extremely
heavy mulching, reduce your width of cut,
mow slowiyand raise the rear of the lawn
mower one wheal adjuster setting higher
than the front.

• For better grass bagging and most cutting
conditions,the engine speed should be set

• Porea in cloth grass catchers can become

this, regularly hose catcher off with water

• Certain types of grass and grass comr_ions
may require that an area be mulched a

acrose or peq_e_rK_jlar to the tirst cut path.
• Chenge your cutlJngpaftem from weak to

• The blade can be sharpened with a file
or on a grinding wheel. 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.

GRASSCATCHER
• The graas catcher may be hosed with
water, but mint be dry when used.
NOTE: Although multi--viscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, these multi--viscosity
oils
will result in increased oil consumption
when used above 32°R Check your
engine oil level more frequently to avoid
possible engine damage from running
low on oil.
Change the oil after every 25 hours of
operation or at least once a year if the
lawn mower is not used for 25 hours in
one year.
Check the crankcase oil level before
starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.

• Keep finished surfaces and wheels free
of all gasoline, oil, etc.
• We DO NOT recommend using a
garden hose to clean lawn mower
unless the electdcal system, muffler, air
filter and carburetor are covered to
keep water out. Water in engine can
result in shortened engine life.
TO ADJUST HANDLE
&CAUTION:
Before performing any
service or adjustments:
• Release control bar and stop engine.
• Make sure the blade and all moving
parts have completely stopped.
• Disconnect spark plug wire from spark
plug and place where it cannot come in
contact with plug.
LAWN MOWER
The handle on your lawn mower has
three (3) height positions - adjust to height
that suits you.
• Squeeze the bottom ends of lower
handle towards each other until the pin
in handle can be inserted into one of
the three height adjustment holes.

CARBURETOR
Your carburetor has a non-adjustable fixed
main jet for mixture control. If your engine
does not operate properly due to suspected
carburetor problems, take your lawn.,mower to
an authorized service center for repair or
adjustment.
IMPORTANT: Never tsmper with the engine
governor,which is factory set for proper
engine speed. Overspeeding the engine
above the factory high speed setting can be
dangerous, if you think the engine-governed
high speed needs adjusting, contact your
nearest AUTHORIZED service center,which
has proper equipment and experience to
make any necessary adjustments.
ENGINE SPEED
Your engine speed has been factory set. Do
not attempt to increase engine speed or it
may result in personal injury. If you believe
that the engine is runningtoo fast or too slow,
take your lawn mower to an authorized
service center for repair and adjustment.

FUEL SYSTEM
IMPORTANT:
It is important to prevent
_uUmdeposits from forming in essential
el 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 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 until the
fuel lines and carburetor are empty.

i damage

may
occur.or carburetor cleaner
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 addin_l
stabilizer to allow the stabilizer to raacn
the carburetor. Do not drain the ._as tank
and carburetor if using fuel stabihzer.
14
ENGINE OIL
• If possible, store your unit indoors and
cover it to give protection from dust and
dirt.
. Cover your unit with a suitable protective cover that does not retain moisture.
Do not use plastic. Plastic cannot
breathe which allows condensation to
form and will cause your unit to rust.
IMPORTANT:
Never cover mower while
engine and exhaust areas are still warm.
Drain oil (with engine warm) and replace
with clean engine oil. (See "ENGINE in
the Maintenance section of this manual).
CYLINDER
Remove spark plug.
Pour one ounce (29 ml) of oil through
spark plug hole into cylinder.
• Pull starter handle slowly a few times to
distribute oil.
• Replace with new spark plug.
OTHER
• Do not store gasoline from one season
to another.
• Replace your 9asoline can if your can
starts to rust. Rust and/or dirt in your
gasoline will cause problems.
