I. CHILDREN
WARNING: CHILDREN CAN
BE SERIOUSLY INJURED OR
KILLED BY THIS EQUIPMENT.
Carefully read and follow all of
the safety instructions below.
The American Academy of Pediatrics recommends that children be a minimum of 12 year
of age before operating a pedestrian controlled lawn mower and a minimum of 16 years
of age before operating a riding lawn mower.
Tragic accidents can occur if the op er a tor is
not alert to the presence of children. Children
are often attracted to the ma chine and the
mowing activity. Never assume that children
will remain where you last saw them.
• Keep children out of the mowing area
and under the watchful care of a re spon si ble adult other than the operator.
• Be alert and turn machine off if chil dren
enter the area.
• Before and while walking back wards, look
behind and down for small chil dren.
• Never allow children to operate the
machine.
II. GENERAL OPERATION
• Read, understand, and follow all
in struc tions on the machine and in the
manual(s) before starting. Be thor ough ly
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 dis charge opening at all times.
• Only allow responsible individuals, who
are familiar with the in struc tions, 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
blade. Stay behind the handle when the
engine (motor) is running.
• Be sure the area is clear of other people
before mowing. Stop ma chine if anyone
enters the area.
• Do not operate machine bare footed or
while wearing sandals. Al ways wear
substantial footwear with good ankle
support while mowing.
• Do not pull mower backwards unless
absolutely nec es sary. Always look down
and behind 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 blade when crossing gravel
surfaces.
• Do not operate the mower without
proper guards, plates, grass catcher or
oth er 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 grav el
drives, walks, or roads.
• Never leave a running machine unattended.
• Stop the engine (motor) and wait until
the blade comes to a complete stop
before clean ing the machine, removing
the grass catcher, or unclogging the
discharge chute.
• 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.

firm hold on the handle; walk, never run.
3
• Disengage the drive system, if so
equipped, before starting the engine
(motor).
• If the equipment should start to vi brate
abnormally, stop the engine (motor)
and check immediately for the cause.
Vibration is generally a warning of
trouble.
• Always wear eye protection when op er at ing machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
• When loading or unloading this machine, do not exceed the maximum
recommended operation angle of 15°.

footwear, eye protection, and hearing
protection. Do not mow in shorts or
open toed footwear.
Always let someone know you are outside
mowing.
III. SLOPE OPERATION
Slopes are a major factor related to slip &
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: nev er
up and down. Exercise extreme caution
when changing direction on slopes.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, bumps or hidden
objects. Uneven terrain could cause
a slip and fall accident. Tall grass can
hide obstacles.
DO NOT:
• Do not mow near drop-offs, ditches
or embankments. You could lose your
footing or balance.
• Do not mow on wet grass or excessively steep slopes. Poor footing could
cause a slip and fall accident.
IV. SAFE HANDLING OF GASOLINE
To avoid personal injury or property damage, 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 container 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. Dis con nect
the spark plug wire, and keep the wire
away from the plug to prevent ac ci den tal starting.
• Keep all nuts and bolts tight to be sure the
equipment is in safe working condition.
• Never tamper with safety devices.
Check their proper operation reg u lar ly.
Never do anything to interfere with the
intended function of a safety device or
reduce the protection provided by a
safety device.
• Keep machine free of grass, leaves, or
other debris build-up. Clean oil or fuel spillage. Allow machine to cool before storing.
• Stop and inspect the equipment if you
strike an object. Repair, if nec es sary,
before restarting.
• Never attempt to make wheel height adjustments while the engine is running.
• Grass catcher components are sub ject
to wear, dam age, and de te ri o ra tion,
which could expose moving parts or
allow objects to be thrown. Frequently
check com po nents and replace with
man u fac tur er’s recommended parts,
when necessary.
• Mower blades are sharp and can cut.
Wrap the blade(s) or wear gloves, and
use extra caution when ser vic ing them.
• Do not change the engine governor setting or overspeed the engine.
• Maintain or replace safety and instruction labels, as necessary.

BEFORE STARTING ENGINE
ADD OIL
Your lawnmower is shipped without oil in
the engine. For type and grade of oil to
use, see “EN GINE” 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 13.5
oz. due to residual oil in engine from the
manufacturers 100% quality testing. When
changing oil you may need 15.5 oz.
TO STOP ENGINE
• To stop engine, release operator presence con trol 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.
10
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 han dle and
pull starter handle quickly. Do not allow
starter rope to snap back.
MOWING TIPS
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 over load ing the
en gine 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 pre vi ous ly
cut path and mow slowly.
• For side discharge operation, cut in
a coun ter clock wise di rec tion, start ing
at the outside of the area to be cut, in
order to spread grass clip pings more
evenly and to put less load on the
engine. To keep clip pings off of walkways, flower beds, etc., make the first
cuts in a clock wise direction.
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 clip pings 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 bio de grade
quick ly to provide nu tri ents 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
in ter feres with the mulch ing 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 over grown
it will be nec es sary to raise the height
of cut to reduce pushing effort and to
keep from over load ing the engine and
leaving clumps of mulched grass. For
ex tremely heavy grass, reduce your
width of cut by overlapping previously
cut path and mow slowly.
• If a trail of grass clipping is left on the
right side of the lawn mower during rear
discharge operation, mow in a clockwise direction with a small overlap to
collect the clippings on the next pass.
• 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.
MAX 1/3
• Certain types of grass and grass
con di tions may re quire that an area be
mulched a second time to com pletely
hide the clip pings. 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.

TO SHARPEN BLADE
NOTE: We do not recommend sharp en ing the blade - but if you do, be sure
the blade is balanced. An un bal anced
blade will cause eventual damage to lawn
mower or engine.
• The blade can be sharp ened 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 ex posed. 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.
GRASS CATCHER
• The grass catcher may be hosed with
water, but must be dry when used.
• Check your grass catcher often for damage or de te ri o ra tion. Through normal use
it will wear. If catcher needs replacing,
replace only with ap proved replacement
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 SJ–SN.
Select the oil's SAE viscosity grade
according to your expected operating
temperature.
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.
* NOTE: An oil change is not required but
if you desire to change the oil follow the
procedure below.

Check the crankcase oil level before
starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.
TO CHANGE ENGINE OIL
NOTE: Before tipping lawn mower to
drain oil, empty fuel tank by running engine until fuel tank is empty.
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2. Remove engine oil cap; lay aside on a
clean surface.
3. Tip lawn mower on its side as shown
and drain oil into a suitable container.
Rock lawn mower back and forth to remove any oil trapped inside of engine.
CAUTION: Petroleum solvents, such
as ker o sene, are not to be used to clean
car tridge. They may cause de te ri o ra tion
of the cartridge. Do not oil car tridge. Do
not use pres sur ized air to clean or dry
car tridge.
4. Install cartridge, then replace cover.

4. Wipe off any spilled oil from lawn
mower or side of engine.
5. Slowly pour oil down the oil fill spout,
stopping every few ounces to check
the oil level with the dipstick.
6. Stop adding oil when you reach the
FULL mark on the dipstick. Wait a minute to allow oil to settle.
7. Continue adding small amounts of oil,
rechecking the dipstick until oil level
settles at FULL. DO NOT overfill, or
engine will smoke heavily from the
muffler on startup.
8. Always be sure to retighten oil dipstick
before starting engine.
9. Re con nect spark plug wire to plug.
AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air filter.
Replace the air filter every 100 hours of
operation or every season, whichever occurs first. Service air cleaner more often
under dusty conditions.
TO CLEAN AIR FILTER
1. Remove cover.
2. Carefully remove cartridge.
3. Clean by gently tapping on a flat surface. If very dirty, replace cartridge.
MUFFLER
Inspect and replace corroded muffler as it
could create a fire hazard and/or dam age.
SPARK PLUG
Replace spark plug at the beginning of
each mowing season or after every 100
hours of operation, whichever occurs
first. Spark plug type and gap setting
are shown in the “PROD UCT SPEC I FI CA TIONS” section of this manual.
CLEANING
IMPORTANT: For best performance,
keep mower housing free of built-grass
and trash. Clean the underside of your
mower after each use.
CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with 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.
• With the exception of the water washout port (if equipped), we do not recommend using a garden hose to clean
the outside of your lawn mower unless
the elec tri cal system, muffler, air filter
and carburetor are covered to keep
water out. Water in engine can result in
shortened engine life.
