throwing objects. Failure to observe the following safety instructions could result in
serious injury or death.
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
• 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 with 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.
III. 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.
IV. SERVICES

with the engine running. Allow engine
to cool before refueling. Do not
smoke.
-Never refuel the machine indoors.
- Never store the machine or fuel
container inside where there is an
open flame, such as a water heater.
Never run a machine inside a closed
area.
Never make adjustments or repairs with
the engine (motor) running. Disconnect
the spark plug wire, and keep the wire
away from the plug to prevent acciden-
tal starting.
• Keep nuts and bolts, especially blade
attachement bolts, tight and keep
equipment in good condition.
• Never tamper with safety devices.
Check their proper operation regularly.
• Keep machine free of grass, leaves, or
other debris build-up. Clean oil or fuel
spillage. Allow machine to cool before
storing.

strike an object. Repair, if necessary,
before restarting.
• Never attempt to make wheel height
adjustments while the engine (motor) is
running.
• Grass catcher components are subject
to wear, damage, and deterioration,
which could expose moving parts or
allow objects to be thrown. Frequently
check components and replace with
manufacturer's recommended parts,
when necessary.
• Mower blades are sharp and can cut.
Wrap the blade(s) or wear gloves, and
use extra caution when servicing them.

BEFORE STARTING ENGINE
OIL
Your lawn mower is shipped without oil in
the engine.
• Be sure mower is level and area
around oil fill is clean.
• Remove engine oil plug and fill to the
top of slot in filler hole.
NOTE: Allow oil to settle down into
engine for accurate 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.
• Reinstall engine oil plug and tighten.
• 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.
7
ADD GASOUNE
• Fill fuel 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.
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 fuel tank, start the
engine and let it run until 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 fuel tank
or permanent damage may occur.
ACAUTION: 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.
TO START ENGINE
NOTE: Due to protective coatings on the
engine, a small amount of smoke may be
present during the initial use of the
product and should be considered
normal.
• To start a cold engine, push primer
three (3) times before trying to start.
Use a firm push. This step is not
usually necessary when starting an
engine which has already run for a few
minutes.
• 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, 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.

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.
• For side discharge lawn mowers,
cutting in a counter-clockwise direction,
starting at the outside of the area to be
cut, spreads grass clippings more
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 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 free of built-up grass and
trash. See "Cleaning" in MAINTENANCE
section of this manual.
• The special mulching blade will recurthe
grass clippings many times and reduce
them in size 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 nutrients
for the lawn. Always mulch with your
highest engine (blade) speed as this will
provide the best recutting action of the
blades.
• Avoid cutting your 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 aftemoon. 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 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 grass. For extremely
heavy mulching, reduce your width of cut
by overlapping previously cut path and
mow slowly.
• 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 cutting pattem 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.
