• Do not operate the mower when bare-
foot or wearing open sandals. Always
wear substantial foot wear.
• Do not pull mower backwards unless abso-
lutely necessary. Always Iookdown and be-
hind before and while moving backwards.
• Never direct discharged material toward
anyone. Avoid discharging material
against a wall or obstruction. Material may
richochet back toward the operator. Stop
the blade when crossing gravel surfaces.
• Do not operate the mower without prop-
er 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 ap-
proved 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; walk, never run.
• Disengage the self-propelled mech-
anism or drive clutch on mowers so
equipped before starting the engine.
• If the equipment should start to vibrate
abnormally, stop the engine (motor) and
check immediately for the cause. Vibra-
tion is generally a warning of trouble.
• Always wear safety goggles or safety glass-
es with side shields when operating mower.
II. SLOPE OPERATION
Slopes are a major factor related to slip &
fall accidents which can result in severe
injury. All slopes require extra caution. If
2 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. Neverassume 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 machine.
* Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
IV. SAFE HANDLING OF GASOLINE
Use extreme care in handling gasoline.
Gasoline is extremely flammable and the
vapors are explosive.
* Extinguish all cigarettes, cigars, pipes
and other sources of ignition.
* Use only an approved container.
* Never remove gas cap or add fuel with
the engine running. Allow engine to
cool before refueling.
* Never refuel the machine indoors.
* Never store the machine or fuel contain-
er where there is an open flame, spark
or pilot light such as a water heater or
on other appliances.
* Never fill containers inside a vehicle, on
a truck or trailer bed with a plastic liner.
Always place containers on the ground
away from your vehicle before filling.
* Remove gas-powered equipment from
the truck or trailer and refuel it on the
ground. If this is not possible, then
refuel such equipment with a portable
container, rather than from a gasoline
dispenser nozzle.
* Keep the nozzle in contact with the rim
of the fuel tank or container opening at
all times until fueling is complete. Do
not use a nozzle lock-open device.
* If fuel is spilled on clothing, change
clothing immediately.
* Never overfill fuel tank. Replace gas
cap and tighten securely.
V. GENERAL SERVICE
* Never run 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 accidental starting.
* Keep nuts and bolts, especially blade
attachment bolts, tight and keep equip-
ment 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 spill-
age. Allow machine to cool before storing.
* Stop and inspect the equipment if you
strike an object. Repair, if necessary,
before restarting.
* Never attempt to make wheel height
adjustments while the engine 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 compo-
nents 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.
* Do not change the engine governor set-
ting or overspeed the engine.
* Maintain or replace safety and instruc-
tion labels, as necessary.
AWARN[NG: This lawn mower is equipped with an internal combustion engine and
should not be used on or near any unimproved forest-covered, brush-covered or
grass-covered land unless the engine's exhaust system is equipped with a spark
arrester meeting applicable local or state laws (if any). If a spark arrester is used, it
should be maintained in effective working order by the operator.

IMPORTANT:
• 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. See "TO
CHANGE ENGINE OIL" in the Mainte-
nance section of this manual.
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 fresh-
ness.
& CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
,_ CAUTION: Alcohol blended fuels
(called gasohol or using ethanol or metha-
nol) 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. Empty 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.
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.
& CAUTION: DO NOT overfill engine with
oil, or it will smoke heavily from the muffler
on startup.
1. Be sure lawnmower is level.
2. Remove oil dipstick from oil fill spout.
3. You receive a container of oil with the
unit. Slowly pour the entire container
down the oil fill spout into the engine.
NOTE: Initial oil fill requires only 14 oz.
due to residual oil in engine from the
manufacturers 100% quality testing. When
changing oil you may need 16 oz.
4. Insert and tighten dipstick.

TO STOP ENGINE
• To stop engine, release operator pres-
ence control bar.
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.
NOTE: Your engine is equipped with an
automatic choke system. No priming or
choking is required before starting.
• To start engine, hold operator presence
control bar down to the handle and pull
starter handle quickly. Do not allow
starter rope to snap back.
MOWING TiPS
,A CAUTION: Do not use de-thatcher
blade attachments on your mower. Such
attachments are hazardous, will damage
your mower and could void your warranty.
• 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 cut-
ting 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-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 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 recut-
ting 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
afternoon. At this time the grass has
dried, yet the newly cut area will not be
exposed to direct sunlight.
• 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
grass, reduce your width of cut by overlap-
ping previously cut path and mow slowly.
MAX 1/3
/V
• 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 sec-
ond cut, mow across (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.

GENERAL RECOMMENDATIONS
The warranty on this lawn mower does not
cover items that have been subjected to
operator abuse or negligence. To receive
full value from the warranty, operator must
maintain unit as instructed in this manual.
Some adjustments will need to be made
periodically to properly maintain your unit.
At least once a season, check to see if
you should make any of the adjustments
described in the Service and Adjustments
section of this manual.
• At least once a year, replace the spark
plug, clean or replace air filter element
and check blade for wear. A new spark
plug and clean/new air filter element
assure proper air-fuel mixture and help
your engine run better and last longer.
• Follow the maintenance schedule in this
manual.
BEFORE EACH USE
• Check engine oil level.
• Check for loose fasteners.
LUBRICATION
Keep unit well lubricated
(See "LUBRICATION CHART").

Always observe safety rules when per-
forming any maintenance.
TIRES
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm rubber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
BLADE CARE
For best results, mower blade must be kept
sharp. Replace bent or damaged blades.
A CAUTION: Use only a replacement
blade approved by the manufacturer of
your mower. Using a blade not approved
by the manufacturer of your mower is haz-
ardous, could damage your mower and
void your warranty.
TO REMOVE BLADE
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2. Turn lawn mower on its side. Make
sure air filter and carburetor are up.
3. Use a wood block between blade and
mower housing to prevent blade from
turning when removing blade bolt.
NOTE: Protect your hands with gloves
and/or wrap blade with heavy cloth.
4. Remove blade bolt by turning counter-
clockwise.
5. Remove blade and attaching hardware
(bolt, Iockwasher and hardened washer).
TO REPLACE BLADE
1. Position blade on the blade adapter
aligning the two (2) holes in the blade
with the raised lugs on the adapter.
2. Be sure the trailing edge of blade (oppo-
site sharp edge) is up toward the engine.
3. Install the blade bolt with the lock
washer and hardened washer into
blade adapter and crankshaft.
4. Use block of wood between blade and
lawn mower housing and tighten the
blade bolt, turning clockwise.
• The recommended tightening torque is
35-40 ft. Ibs.

IMPORTANT: Blade bolt is heat treated.
If bolt needs replacing, replace only with
approved bolt shown in the Repair Parts
section of this manual.
TO SHARPEN BLADE
NOTE: We do not recommend sharp-
ening the blade - but if you do, be sure
the blade is balanced. An unbalanced
blade will cause eventual damage to lawn
mower or engine.
• 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.
GoRASSCATCHER
The grass catcher may be hosed with
water, but must be dry when used.
Check your grass catcher often for dam-
age or deterioration. Through normal
use it will wear. If catcher needs replac-
ing, replace only with approved replace-
ment catcher shown in the Repair Parts
section of this manual. Give the lawn
mower model number when ordering.
ENGINE
LUBRICATION
Use only high quality detergent oil rated
with API service classification SG-SL.
Select the oil's SAE viscosity grade accord-
ing to your expected operating temperature.
SAE VISCOSITY GRADES
F -20 0 30 32 40 60 80 100
c -_o -2; -1; ; lo _o _o 4;
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
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°F. 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.
