I. GENERAL OPERATION
• Read, understand, and follow all
instructions on the machine and in the
manual(s) before starting. Be thor-
oughly familiar with the controls and
the proper use of the machine before
starting.
• Do not put hands or feet near or under
rotating parts. Keep clear of the
discharge opening at all times.
• Only allow responsible individuals,
who are familiar with the instructions, to
operate the machine.
• Clear the area of objects such as
rocks, toys, wire, bones, sticks, etc.,
which could be picked up and thrown
by the blade.
• Be sure the area is clear of other
people before mowing. Stop machine if
anyone enters the area.
• Do not operate the mower when
barefoot or wearing open sandals.
Always wear substantial foot wear.
• Do not pull mower backwards unless
absolutely necessary. Always look
down and behind before and while
moving backwards.
• Do not operate the mower without
proper guards, plates, grass catcher or
other safety protective devices in place.
• See manufacturer's instructions for
proper operation and installation of
accessories. Only use accessories
approved by the manufacturer.
• Stop the blade(s) when crossing gravel
drives, walks, or roads.
• Stop the engine (motor) whenever you
leave the equipment, before cleaning
the mower or unclogging the chute.
• Shut the engine (motor) off and wait
until the blade comes to complete stop
before removing grass catcher.
• Mow only in daylight or good artificial
light.
• Do not operate the machine while
under the influence of alcohol or drugs.
• Never operate machine in wet grass.
Always be sure of your footing: keep a
firm hold on the handle and walk; never
run.
• Disengage the self-propelled mecha-
nism or drive clutch on mowers so
equipped before starting the engine
(motor).
• If the equipment should start to vibrate
abnormally, stop the engine (motor)
and check immediately for the cause.
Vibration is generally a warning of
trouble.
• Always wear safety goggles or safety
glasses with side shields when operat-
ing mower.
II. SLOPE OPERATION
Slopes are a major factor related to slip
and fall accidents which can result in
severe injury. All slopes require extra
caution. If you feel uneasy on a slope, do
not mow it.
DO:
• Mow across the face of slopes: never
up and down. Exercise extreme caution
when changing direction on slopes.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, or bumps. Tall
grass can hide obstacles.
DO NOT:
• Do not trim near drop-offs, ditches or
embankments. The operator could lose
footing or balance.
• Do not trim excessively steep slopes.
• Do not mow on wet grass. Reduced
footing could cause slipping.
IlL CHILDREN
Tragic accidents can occur if the operator
is not alert to the presence of children.
Children are often attracted to the
machine and the mowing activity. Never
assume that children will remain where
you last saw them.
• Keep children out of the trimming area
and under the watchful care of another
responsible adult.
• Be alert and turn machine off if children
enter the area.
• Before and while walking backwards,
look behind and down for small
children.
° Never allow children to operate the
machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.

BEFORE STARTING ENGINE
ADD OIL
Your lawnmower is shipped without oil in
the engine. For type and grade of oil to
use, see "ENGINE" in the Maintenance
section of this manual.
A CAUTION: DO NOT overfill engine with
oil, or it will smoke on startup.
1. Be sure lawnrnower is level and area
around oil fill is clean.
2. Remove oil dipstick from oil fill spout.
Make sure that rim of spout is clean.
3. You receive a container of oil with the
unit. Slowly pour 3/4 (15 oz.) of the oil
from the container down the oil fill
spout into the engine.
4. Wait one minute to allow oil to settle.
Insert and tighten dipstick, then
remove it to check oil level.
5. Continue adding small amounts of oil
and rechecking the dipstick until it
reads full. DO NOT overfill, or engine
will smoke on startup.
6. Always be sure to retighten oil dipstick
before starting engine.
• 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
• Fill fuel tank to bottom of tank filler neck.
Do not overfill 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.
_1,CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
A CAUTION: 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 carbu-
retor cleaner products in the fuel tank or
permanent damage may occur.

TO START ENGINE
NOTE:Dueto protectivecoatingsonthe
engine,a small amount of smoke may be
present during the initial use of the
product and should be considered
normal.
1. To start a cold engine, push primer
three (3) times before tryingto start.
Use a firm push. This step is not
usually necessary when starting an
engine which has already run for a few
minutes.
2. 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 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.
MOWINGTIPS
• 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: Forbest performance, keep
mower housing h'ee of built-up grass and
trash. See "CLEANING" in the Maintenance
section of this manual.
• The special mulching blade will recut the
grass clippings many times and reduce
them insize so that as they fall onto the
lawn they will disperse into the grass and
not be noticed. Also, the mulched grass
will biodegrade quickly to provide nuf_ients
for the lawn. Always mulch withyour
highest engine (blade) speed as this will
provide the best recutting action of the
blades.
• Avoid cutting your lawn when itis wet. Wet
grass tends to form dumps and interferes
with the mulchingaction. The best time to
mow your lawn isthe early afternoon. At
this time 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 _awn mower cuts
off only the top one-third of the grass
blades. If the lawn is overgrown it willbe
necessary to raise the height of cut to
reduce pushing effortand to keep from
overloading the engine and leaving
dumps of mulched grass. For extremely
heavy grass, reduce your width of cut by
overlapping previously cut path and mow
slowly.
MAX 1/3
Certain types of grass and grass conditions
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 cutting pattern from week to
week. Mow north to south one week then
change to east to west the next week. This
will help prevent matting and graining of the
lawn.

GRASS CATCHER
• The grass catcher may be hosed with
water, but must be dry when used.
• Check your grass catcher often for
damage or deterioration. Through
normal use it will wear. If catcher needs
replacing, replace only with a manufac-
turer approved replacement catcher.
Give the lawn mower model number
when ordering.
DRIVE WHEELS
Check rear drive wheels each time you
mow to be sure they move freely. The
wheels not turning freely means trash,
grass cuttings, etc., may be inside the
drive wheel and dust cover area and must
be cleaned out to free drive wheels.
If necessary to clean the drive wheels,
check both rear wheels.
1. Remove hubcaps and Iocknuts.
2. Remove wheels from wheel adjuster
axles.
3. Remove any trash or grass cuttings
from inside the dust cover, pinion and/
or drive wheel gear teeth.
4. If you remove the drive pinions, wipe
clean with dry cloth. Reassemble dry.
Do not lubricate. Do not use oil or
grease.
NOTE: The pinion gears, on both sides of
the mower, are the same, however, they
must be installed correctly. If installed
incorrectly, the drive system will not work.
5. There are arrows embossed on both
sides of the pinion gear. With the
arrow at the top of the pinion, the arrow
must point towards the front of the
mower. If the arrow points to the rear
of the mower, turn the pinion around,
then assemble to mower.
6. Place wheels back on adjuster axles.
7. Replace Iocknuts and hubcaps.

CLEANING
IMPORTANT: For best performance,
keep mower housing free of built-up grass
and trash. Clean underside of mower
housing after each use.
&CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with the spark
plug.
• Clean the underside of your lawn
mower by scraping to remove build-up
of grass and trash.
• Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine life.
• 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
electrical system, muffler, air filter and
carburetor are covered to keep water
out. Water in engine can result in
shortened engine life.
