,AWARNING: 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.
_ILCAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.

the engine.
•Be sure mower is level and area around oil
fillis clean.
•Remove engine oilcap and fillto the full
line on the dipstick.
NOTE: Allow oil to settle down into engine
for accurate dipstick reading.
•Engine holds 20 ozs. of oil. For type and
grade of oil to use, see "ENGINE" in
Maintenance section of this manual.
•Pour oil slowly. Do not over fill.
• Check oil level before each use. Add oil if
needed. Fillto full line on dipstick.
•To read proper level, tighten engine oil cap
each time.
•Reinstall engine oil cap and tighten.
•Change the oil after every 25 hours of
operation or each season. You may need
to change the oilmore often under dusty,
dirty conditions.
ADD GASOUNE
•Fillfuel 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.

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.
•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.
MULCHING MOWING TIPS
IMPORTANT: For best performance, keep
mower housing free of built-upgrass and
trash. See "Cleaning" in Maintenance section
of this manual.
•The special mulching blade will recut the
grass clippings many times and reduce
them in size so that as they fall ontothe
lawn they will disperse into the grass and
not be noticed. Also, the mulched grass
will biodegrade quickly to provide nutrients
for the lawn. Always mulchwith your
highest engine (blade) speed as this will
provide the best recuttingaction of the
blades.
• Avoid cuttingyour lawn when it is wet. Wet
grass tends to form clumps and interferes
with the mulching action. The best time to
mow your lawn is the early afternoon. At
thistime the grass has dried and the newly
cut area will not be exposed to the direct
sun.
•For best results, adjust the lawn mower
cutting height so that the lawn mower cuts
off onlythe 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 effortand to keep from
overloading the engine and leaving
clumps of mulched grass. For extremely
beaw mulching, reduce your width of cut
by overlapping previously cut path and
mow slowly.
/3
• Certain types of grass and grass condi-
tions may require that an area be mulched
a second time to completely hide the
clippings. When doing a second cut, mow
across or perpendicular to the first cut path.
•Change your cuffing pattem from week to
week. Mow northto south one week then
change to east to west the next week. This
will help prevent matting and graining of
the lawn.

FUELSYSTEM
IMPORTANT: It is importantto prevant gum
deposits from forming in essential fuel system
partssuch as carburstor,f fuel filter,fuel hose
or tank during storage. Also, experience
indicates that alcohol blended fuels ( called
gesohoforusingethand or mettmnol)can
attract moisture which leads to ssparation ant
fo_ of acids dunng storage.Acidicgas
can damage the fuel system of an engine
while in storage.
13
• 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 usingfuel stabilizer.
ENGINEOIL
Drain oil (with engine warm) and replace with
clean engine oil. (See "ENGINE" in the
Maintenance section of this manual).
CYUNDER
