GENERALOPERATION
Read this operator's manual carefully in its entirety •
before attempting to assemble this machine.
Read, understand, and follow all instructions on
the machine and in the manual(s) before
operation. Be completely familiar with the controls
and the proper use of this machine before •
operating it. Keep this manual in a safe place for
future and regular reference and for ordering
replacement parts.
Your rotary mower is a precision piece of power
equipment, not a plaything. Therefore, exercise
extreme caution at all times. Your unit has been
designed to perform one job: to mow grass. Do not
use itfor any other purpose.
Never allow children under 14 years old to operate
a power mower. Children 14 years old and over
should only operate mower under close parental •
supervision. Only responsible individuals who are
familiar with these rules of safe operation should
be allowed to use your mower. •
Keep the area of operation clear of all persons,
particularly small children and pets. Stop engine
when they are in the vicinity of your mower to help
prevent blade contact or thrown object injury. •
Although the area of operation should be
completely cleared of foreign objects, an object
may have been overlooked and could be
accidentally thrown by the mower in any direction
and cause serious personal injury to the operator
or any others allowed in the area.
Wear sturdy, rough-soled work shoes and close-
fitting slacks and shirts. Shirts and pants that cover
the arms and legs and steel-toed shoes are
recommended. Do not wear loose fitting clothes or
jewelry. They can be caught in moving parts. •
Never operate aunit in bare feet, sandals, slippery
or light weight (e.g. canvas) shoes. •
Always wear safety glasses or safety goggles
during operation or while performing an
adjustment or repair, to protect eyes from foreign
objects that may be thrown from the machine in
any direction.
Thoroughly inspect the area where the equipment
is to be used. Remove all stones, sticks, wire,
bones, toys and other foreign objects which could
be picked up and thrown by the mower in any
direction and cause serious personal injury to the
operator or any others allowed in the area. Plan
your mowing pattern to avoid discharge of material
toward roads, sidewalks, bystanders and the like.
To help avoid a thrown objects injury, keep
children, bystanders and helpers at least 75 feet
from the mower while it is in operation.
Do not put hands or feet near or under rotating
parts. Keep clear of discharge opening at all times
as the rotating blade can cause injury.
Many injuries occur as a result of the mower being
pulled over the foot during afall. Do not hang on to
the mower if you are falling; release the handle
immediately.
Never pull the mower toward you while you are
walking. If you must back the mower away from a
wall or obstruction first look down and behind, and
then follow these steps:
a. Step back from the mower to fully extend your
arms.
b. Besure you are well balanced with sure
footing.
c. Pull the mower back slowly, no more than half
way toward you.
d. Repeat these steps as needed.
Do not operate the mower while under the
influence of alcohol or drugs.
Do not engage the self-propelled mechanism on
units so equipped while starting engine.

SlopeOperation
• For your safety, use the slope gauge included as
part of this manual to measure slopes before
operating this unit on a sloped or hilly area. If the
slope is greater than 15 degrees as shown on the
slope gauge, do not operate this unit on that area
or serious injury could result.
Do:
Mow across the face of slopes; never up and
down. Exercise extreme caution when changing
direction on slopes.
Watch for holes, ruts, hidden objects, or bumps.
Tall grass can hide obstacles.
• Always be sure of your footing. A slip and fall can
cause serious personal injury. If you feel you are
losing your balance release the blade control
handle immediately and the blade will stop in less
than 3 seconds.
Donot:
• Do not mow near drop-offs, ditches or
embankments. The operator could lose footing or
balance.
• Do not mow slopes greater than 15 degrees as
shown on the slope gauge.
• Do not mow on wet grass. Reduced footing could
cause slipping.
Children
Tragic accidents can occur if the operator is not
alert to the presence of children. Children are often
attracted to the mower 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 responsible adult other than
the operator.
Be alert and turn mower off if a child enters the
area.
Before and while moving backwards, look behind
and down for small children or other objects.
Never allow children under age 14 to operate the
mower. Children 14 years of age and above
should read and understand the operation
instructions and safety rules inthis manual.
Use extreme care when approaching blind
corners, shrubs, trees, or other objects that may
obscure your vision of a child or hazard.
Service
Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
Use only an approved gasoline container.
Never remove gas cap or add fuel while the engine
is running. Allow engine to cool at least two
minutes before refueling.
Replace gasoline cap securely and wipe off any
spilled gasoline before starting the engine as it
may cause a fire or explosion.
Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
Never refuel machine indoors because flammable
vapors will accumulate in the area.
Never store the machine or fuel container inside
where there is an open flame or spark such as a
gas water heater, space heater, or furnace.
Never run an engine inside a closed area.

Primer
The primer isused to pump gas intothe carburetor. Use
itto start a cold engine, but do notuse itto restart a
warm engine after short shutdown.
CasterWheels
Your mower is equipped with caster wheels in front.
The casters can be locked in a straight ahead position
for mowing on hills,or can be left unlocked to swivel
freely on level ground.
GrassBag
The grass bag is equipped with a bag-fill indicator to
add convenience to your work. While the mower is
running, air willflow through the bag and into the "sail."
Ifthe grass catcher is empty, air flows through easily
pushing the sail up. If the grass catcher is full, air does
not flow through it allowing the sail to fall. So the
position of the sail acts as a bag-fill indicator signifying
when to empty the grass bag.
GrassBagAdapter
When installed, it allows the mower to collect clippings
in the grass bag.
SideDischargeChute
When installed allows the mower to discharge clippings
out the side of the deck.
MulchingCover
When installed, the mulching cover aids in a process of
recirculating grass clippings repeatedly beneath the
cutting deck. The ultra-fine clippings are then forced
back into the lawn where they act as a natural fertilizer.
SECTION5: OPERATINGYOURLAWNMOWER
GasAndOilFill-Up
Oil:
• Only use high quality detergent oil rated with API
service classification SF, SG or SH. Use SAE30 oil;
do not use 10W40 oil.
• Fill oil sump and check the oil level following steps
below. See Figure 9.
a. Position the mower on level ground and
clean area around oil fill plug.
b. Remove oil fill plug and dipstick. Wipe

Figure 9
NOTE: Although multi-viscosity oils (5W30, 10W30,
etc.) improve starting in cold weather, these multivis-
cosity oils will result in increased oil consumption when
used above 32°F. Check oil level more frequently to
avoid possible engine damage from running low on oil.
Gasoline
_ WARNING: Never fill fuel tank indoors, or
when engine is running or hot. Do not
smoke when filling fuel tank.
• Clean area around fuel cap. Remove cap. See
Figure 9. Use a funnel to prevent spillage.
• Pour approximately 1.5 quarts of fresh, regular
grade, unleaded gasoline slowly to the fuel tank.
IMPORTANT:Never mix engine oil with gasoline.
• Fill tank to 1/2" below the bottom of the filler neck.
Wipe any fuel spillage. Do not fill fuel tank
completely. Provide space for fuel expansion.
StartingEngine
WARNING: Be sure no one other than the
operator is standing near the lawn mower
while starting or operating.
Never run engine indoors or in enclosed,
poorly ventilated areas. Engine exhaust
contains carbon monoxide, an odorless
and deadly gas.
Keep hands, feet, hair and loose clothing
away from any moving parts on engine
and lawn mower.
• To prevent the unit from sliding, place your foot
firmly against the tire.
• Attach spark plug wire to spark plug. Make certain
the metal cap on the end of the spark plug wire is
fastened securely over the metal tip on the spark
plug.
• Push primer three times. Wait about two seconds
between each push. In cold weather around 55o F
or below, prime five times. Do not prime to restart a
warm engine after a short shutdown.
• Grasp starter handle and pull rope out slowly until
engine reaches the start of compression cycle
(rope will pull slightly harder at this point). Let the
rope rewind slowly.
• Pull rope with a rapid, continuous, full arm stroke.
Keeping a firm grip on the starter handle, let the
rope return to the starter slowly.
10
StoppingEngine
• Release blade control handle to stop the engine
and the blade.
• Disconnect spark plug wire and move away from
spark plug to prevent accidental starting.
LockingCasters
IMPORTANT:If you are cutting grass on a slope, always
lock the front wheel casters of your mower for straight
ahead operation. On level ground you may leave the
casters unlocked to pivot freely.
• To turn the mower on a slope with casters locked,
depress the upper handle and raise the front
wheels slightly.
• To lock caster: Lift and place the lock pin in the
larger hole on each caster. See Figure 10.
• To unlock caster: Lift and place the lock pin inthe
smaller hole to allow casters to rotate freely.
Locked
Unlocked
• The best mowing pattern is one that allows the
clippings to discharge towards the uncut part of the
lawn. This permits recutting of the clippings to
further pulverize them. When cutting high weeds,
discharge towards cut portion, then recut at right
angles to first direction.
• For a healthy lawn, always cut off one-third or less
of the total length of the grass. Lawn should be
trimmed in fall as long as there is growth.
WARNING: If you strike a foreign object,
stop the engine. Remove spark plug wire
from spark plug, thoroughly inspect the
mower for any damage. Repair the damage
before restarting and operating the mower.
Extensive vibration of the mower during
operation is an indication of damage. The
unit should be promptly inspected and
repaired.
HeightAdjustment
Refer to height adjustments section of this manual on
page 14 for instruction on how to adjust the cutting
height and the handle height.
• For best results in mowing, keep the cutting height
position high until it is determined which height is
best for your lawn.
Figure 10
WARNING: Do not mow on slopes with
casters unlocked since the mower can
drift downhill.
UsingYourLawnMower
Your mower is designed to operate as a mulching,
bagging or a side-discharge unit.
WARNING: Do not operate the mower
without the mulching cover, grass bag
adapter or the discharge chute properly
installed and tightly secured.
• Be sure that the lawn is clear of stones, sticks, wire,
or other objects which could damage lawn mower
or engine. Such objects could be accidently thrown
by the mower in any direction and cause serious
personal injury to the operator and others.
• For best results, do not cut wet grass because it
tends to stick to the underside of the mower,
preventing proper discharge of grass clippings, and
could cause you to slip and fall. New grass, thick
grass or wet grass may require a narrower cut.
AttachingTheGrassBag
• Remove three wing knobs holding the mulching
baffle or side discharge chute in place and remove
from unit. See Figure 11.

EngineMaintenance
• A list of key maintenance jobs required for good
performance by the mower over the years follows
here. Follow the accompanying engine manual for
detailed list and instructions.
• Change engine oil after the first two operating
hours and every 25 operating hours thereafter.
Check oil level before starting the engine.
• Service the foam filter in the air cleaner every 25
hours of use and replace the paper filter component
every 100 hours. You may have to service the air
filter more frequently if you are operating the mower
under extremely dusty conditions.
• Clean the engine periodically. Remove dirt and
debris with a cloth or brush. We do not recommend
the use of pressure washers or garden hose to
clean your unit.These may cause damage to
electric components, spindles, pulleys, bearings or
the engine. The use of water will shorten life of the
mower and reduce its serviceability.
• Clean the spark plug and reset the gap to .030" at
least once a season or every 50 hours of operation.
Spark plug replacement is recommended at the
start of each season. Refer to the engine manual,
shipped with this unit, for correct spark plug type.
• Inspect muffler periodically, and replace if
necessary. Damaged mufflers or spark arresters
can create a fire hazard. Make sure to avoid muffler
and surrounding areas while the mower engine is
hot because temperature of these areas of the
engine may exceed 150° F.
SECTION7: MAKINGADJUSTMENTS
HandleHeight
Your mower is shipped with the handle in the higher
height position. To lower the handle height, proceed as
follows.
Remove the starter rope from the rope guide.
Remove the upper handle by removing the hand
knobs and carriage bolts. Lay the upper handle out
of the way, being careful not to bend or kink the
cables.

legs of the lower handle. Remove lower handle
from the mower.
• Turn the lower handle around so the notch on the
bottom of the lower handle is facing forward as
shown in Figure 17. Reassemble, placing the
bottom holes in the handle over the weld pins in the
handle mounting bracket.
• Reassemble the upper handle to the lower handle.
• Place the hairpin clips in the inner holes in the weld
pins and attach the starter rope as instructed in the
Assembly section.
CuttingHeight
IMPORTANT:All wheels must be placed in the same
relative position. For rough or uneven lawns, move the
height adjustment lever to a higher position. This will
help stop scalping of the grass.
FrontWheel
The front wheel cutting height is determined by placing
the axle rod in one of the six height adjustment
positions in each caster assembly on the front wheels.
• To adjust, remove the wing knob from the axle bolt.
See Figure 18.
• Slide the axle bolt and spring washer from the
assembly and select a cutting height.

• With the spring washer on the axle bolt, reinsert the
axle bolt in the square hole desired, through the
wheel assembly. See Figure 18.
• Secure with wing knob previously removed.

season or if the unit will not be used for 30 days or
more. Store the mower in a clean, dry area.
Mower
• Clean underside of the mower following
instructions on page 12.
NOTE: We do not recommend the use of pressure
washers or garden hose to clean your unit. These may
cause damage to electric components, spindles,
pulleys, bearings or the engine. The use of water will
shorten life of the mower and reduce its serviceability.
Inspect and replace/sharpen blade, if required.
Lubricate mower following the lubrication chart in
Figure 14 of this manual.
You can fold your mower's handle for convenient
storage. Follow the steps below for folding.
a. Remove the starter rope from the rope guide.
b. Loosen the two hand knobs on the sides of
the handle, and let the upper handle fold
down to the rear.
c. Move the hairpin clips to the outer hole in the
weld pins on the handle mounting brackets.
d. Remove the carriage bolts and wing knobs
from the lower handle mounting brackets.
e. Spread the sides of the lower handle, and
push it forward and down.
NOTE: When folding the handle for storage or transpor-
tation, be careful not to bend or kink the cable.
Engine
• Follow recommendations in the accompanying
engine manual for off-season storage of the
engine.
• Change oil if it has not been changed in the last
three months. For instructions on how to change oil,
refer to the engine manual.
• Clean engine and remove any grass clippings, dirt,
or chaff from the exterior of the engine.
• Remove any dirt or debris from cooling fins, air
intake screen, levers, and linkage.
Other
Do not store gasoline from one season to another.
Replace your gasoline can if it starts to rust. Rust
and/or dirt in the gasoline will cause problems.
Store unit in a clean, dry area. Do not store next to
corrosive materials, such as fertilizer.
NOTE: If storing in an unventilated or metal storage
shed, be certain to rustproof the equipment by coating
with a light oil or silicone.
