BEFORE STARTING ENGINE
ADD OIL
Your lawnmower is shipped without oil in
the engine. Engine holds 20 oz. of oil.
For type and grade of oil to use, see
_ENGINE" in Maintenance section ofthis
manual.
1. Be sure lawnmower is level and area
around oil fill is clean.
2. Remove engine oil cap and fill to the
full line on the dipstick.Pour oil slowly.
Do not over fill.
NOTE: Allow oil to settle down into engine
for accurate reading. To read proper level,
tighten engine oil cap, then remove it to
read the dipstick.
3. Reinstall engine oil cap and tighten.
•Check oil level before each use. Add
oil if needed. Fill to full line on dipstick.
•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.
ADD GASOLINE
NOTE: Before figingfuel tank, remove
and discard the debr;s plugthat is inside
the tank.
• Fillfuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. Do not mix oil with gaso-
line. Purchase fuel in quantities that
can be used within 30 days to assure
fuel freshness.
AWARNING: Experience indicates that
alcohol blended fuels (caged gasohol or
using ethanol or methanol) can attract
moisture which leads to separation and
formation of acids dudng storage. Acidic
gas can damage the fuel system ofan
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 untilthe fuel lines
and carburetorare empty. Use fresh fuel
next season. See Storage Instructionsfor
additional information. Never usa engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.
A, CAUTION: Filltobottom of gas tank
filler neck. Do not overfill. Wipe off any
spilledoil or fuel. Do not store, spillor
use gasoline near an open flame.
Gasoline filler cap Engine
(Discard debris plug inside)
Primer
TO START ENGINE
NOTE: Due to protective coatings on the
engine, a small amount of smoke may be
present during the initialuse of the
product and should be considered
normal.
1. To start acold engine, push primer
three (3) times before trying to start.
Use afirm push. This step is not
usually necessary when starting an
engine which has already run for a
few minutes.
2. Move throttlecontrol lever to fast
position.
3. Hold operator presence control bar
down to the handle and pull starter
handle quickly. Do not allow starter
rope to snap back.
TO STOP ENGINE
•To stop engine, release operator
presence control bar.
NOTE: In cooler weather itmay 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.

MOWlNGTIPS
•Under certain conditions, such as very
tall grass, it may be necessary to raise
the height of cut to reduce pushing
effortand 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
cuttingconditions, the engine speed
should be set in the fast position.
•Pores in cloth grass catchers can
become filledwith 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 MOWINGTIPS
IMPORTANT: For best performance,
keep mower housing free of built-up
grass and trash. See "CLEANING" in the
Maintenance section of this manual.
•The special mulchingblade will recut
the grass clippings many times and
reduce them in size sothat as they fall
onto the lawn they will disperse intothe
grass and notbe noticed. Also,the
mulched grass will biodegrede quickly
to provide nutrients for the lawn.
A_ways mulch with your highest engine
(blade) speed as this will provide the
best recutting action 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 isthe
eady afternoon. At this time the grass
has dried and the newly cut area will
notbe exposed to the directsun.
•For best results,adjust the lawn mower
cutting height so that the lawn mower
cuts off only the top one-thirdof 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 grass. For
extremely heavy mulching, reduce your
width of cut by overlapping previously
cut path and mow slowly.
•Certain types of grass and grass
conditionsmay require that an area be
mulched a second time to completely
hide the clippings. When doing a
second cut, mow across or perpendicu-
larto the firstcut path.
•Change your cutting pattern from week
to week. Mow north to southone week
then change to east to west the next
week. This will help prevent matting
and grainingof the lawn.

FUEL SYSTEM
IMPORTANT: It isimportant toprevent
gum deposits from forming in essential
fuel system parts such as carburetor, fuel
I_lter,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 duringstorage. Acidic gas can
damage the fuel system ofan engine
while in storage.
1. Drain the fuel tank.
2. 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 formationof
fuel gum deposits duringstorage. Add
stabilizer to gasoline in fuel tank or
storage container. Always followthe mix
ratio found on stabilizer container. Run
engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach
the carburetor. Do notdrainthe 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).
