• Do not engage the self-propelled mechanism on
units so equipped while starting engine.
• 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.
• The blade control handle is a safety device. Never
attempt to bypass its operation. Doing so makes
the safety device inoperative and may result in
personal injury through contact with the rotating
blade. The blade control handle must operate
easily in both directions and automatically return to
the disengaged position when released.
DO NOT:
• Do not mow near drop-offs, ditches or
embankments. The operator could lose footing or
balance.
• Never operate the mower in wet grass. Always be
sure of your footing. A slip and fall can cause
serious personal injury. Keep a firm hold on the
handle and walk, never run. If you feel you are
losing your footing, RELEASE THE BLADE
CONTROL HANDLE IMMEDIATELY and the
blade will stop rotating within three seconds.
• 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.
3. CHILDREN
• Mow only in daylight or good artificial light.
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.
• Stop the blade when crossing gravel drives, walks
or roads.
• If the equipment should start to vibrate abnormally,
stop the engine and check immediately for the
cause. Vibration is generally a warning of trouble.
• Keep children out of the mowing area and under
the watchful care of a responsible adult other than
the operator.
• Shut the engine off and wait until the blade comes
to a complete stop before removing the grass
catcher or unclogging the chute. The cutting blade
continues to rotate for a few seconds after the
engine is shut off. Never place any part of the body
in the blade area until you are sure the blade has
stopped rotating.
• 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 in this manual.
• Never operate mower without proper guards, grass
catcher, plates or other safety protective devices in
place.
• Use extreme care when approaching blind
corners, shrubs, trees, or other objects that may
obscure your vision of a child or hazard.
• Muffler and engine become hot and can cause a
burn. Do not touch.
• Only use accessories approved for this machine
by the manufacturer. Read, understand, and follow
all instructions provided with the approved
accessory.
4. SERVICE
• Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
• If situations occur which are not covered in this
manual, use care and good judgment. Contact
your dealer for assistance. Telephone 1-800-800-
7310 for the name of your nearest dealer.
• 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.
2. SLOPE OPERATION
• Replace gasoline cap securely and wipe off any
spilled gasoline before starting the engine as it
may cause a fire or explosion.
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.
• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
• Never refuel machine indoors because flammable
vapors will accumulate in the area.
DO:
• Mow across the face of slopes; never up and
down. Exercise extreme caution when changing
direction on slopes.
• 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.
• Watch for holes, ruts, hidden objects, or bumps.
Tall grass can hide obstacles.
• Never run an engine inside a closed area.

• To reduce fire hazard, keep mower free of grass,
leaves, or other debris build-up. Clean up oil or
fuel spillage. Allow mower to cool at least 5
minutes before storing.
• After striking a foreign object, stop the engine,
remove the wire from the spark plug, and
thoroughly inspect the mower for any damage.
Repair the damage before starting and operating
the mower.
• Before cleaning, repairing, or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire, and keep
the wire away from the spark plug to prevent
accidental starting.
• Never attempt to make a wheel or cutting height
adjustment 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. For
safety protection, frequently check components
and replace with manufacturer’s recommended
parts, when necessary.
• Check the blade and engine mounting bolts at
frequent intervals for proper tightness. Also,
visually inspect blade for damage (e.g., bent,
cracked or worn). Replace with blade which meets
original equipment specifications listed in this
manual.
• Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves, and use extra caution
when servicing them.
• Keep all nuts, bolts, and screws tight to be sure
the equipment is in safe working condition.
• Do not change the engine governor setting or
overspeed the engine. Excessive engine speeds
are dangerous.
• Never tamper with safety devices. Check their
proper operation regularly.
WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to persons who
read, understand and follow the warnings and instructions in this manual and on the machine.

USINGYOUR ROTARY MOWER
TO START ENGINE AND ENGAGE
BLADE
Be sure that 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.
NOTE: Your engine is a constant speed engine,
which is set at full throttle for best performance.
1. Attach spark plug wire securely to spark plug.
2. Prime engine as instructed in the separate
engine manual.
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 or thick
grass may require a narrower cut.
Blade
Control
Handle
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, never cut off more than one-
third of the total length of the grass. Lawn should
be cut in the fall as long as there is growth.
Recoil Starter
Handle
WARNING: If you strike a foreign
object, stop the engine. Remove wire from
spark plug, thoroughly inspect the mower
for any damage, and 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.
Figure 13
3. Standing behind the unit, depress the blade
control handle and hold it against the upper

SECTION 9: ADJUSTMENTS
WARNING: Do not at any time make
any adjustment to lawn mower without
first stopping engine and disconnecting
spark plug wire.
CARBURETOR ADJUSTMENTS
WARNING: If any adjustments are
made to the engine while the engine is
running (e.g. carburetor), keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
CUTTING HEIGHT ADJUSTMENT
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load. Refer to the separate engine
manual packed with your mower for carburetor
adjustment information.
Adjustment may be made by removing and moving
axle bolts to desired position. Cutting heights will be
raised as axle bolts are moved to a lower hole and
lowered as axle bolts are moved to a higher hole in
the deck. All axle bolts must be mounted in the
same relative position. Cupped washers must be
assembled so that the cupped side of the washers
are against the deck. Refer to Figure 9.
NOTE: A dirty air cleaner will cause an engine to
run rough. Be certain air cleaner is clean and
attached to the carburetor before adjusting
carburetor.
SECTION 10: LUBRICATION
Blade Control - Lubricate the pivot points on the
blade control handle and the brake cable at least
once a season with light oil. See Figure 14. The
blade control must operate freely in both directions.
WARNING: Always stop engine and
disconnect spark plug wire before cleaning,
lubricating or doing any kind of work on
lawn mower.
Blade Control
Handle
Chute Deflector—The torsion spring and pivot
point should be lubricated periodically with light oil
to prevent any rust or binding. Deflector must work
freely.

SECTION 11: MAINTENANCE
WARNING: Be sure to disconnect and
ground the spark plug wire before
performing any repairs or maintenance.
CUTTING BLADE
When removing the cutting blade for sharpening or
replacement, protect hands by using heavy gloves
or a rag to grasp the cutting blade. Remove the bolt
and blade support or bell washer which hold the
blade and adapter to the engine crankshaft.
Remove the blade and adapter from the crankshaft.
NOTE: When tipping the unit, empty the fuel tank
and keep engine spark plug side up.
TROUBLE SHOOTING
Refer to page 14 of this manual for trouble shooting
information.
If the blade is secured to the blade adapter with two
bolts, remove the two small bolts, lock washers and
nuts which hold the blade to the adapter.
12
Download from Www.Somanuals.com. All Manuals Search And Download.
When sharpening the blade, follow the original
angle of grind as a guide. It is extremely important
that each cutting edge receives an equal amount of
grinding to prevent an unbalanced blade. An
unbalanced blade will cause excessive vibration
when rotating at high speeds, may cause damage
to the mower and could break, causing personal
injury.
Blade Mounting Torque
Center Bolt: 450 in. lbs. min., 600 in. lbs. max.
To ensure safe operation of your unit, all nuts and
bolts must be checked periodically for correct
tightness.
DECK
The blade can be tested by balancing it on a round
shaft screwdriver. Remove metal from the heavy
side until it balances evenly. It is recommended that
the blade always be removed from the adapter for
the best test of balance.
The underside of the mower deck should be
cleaned after each use to prevent a buildup of grass
clippings, leaves, dirt or other matter. If this debris is
allowed to accumulate, it will invite rust and
corrosion, and may cause an uneven discharge of
grass clippings at the next cutting.
Before reassembling the blade and the blade
adapter to the unit, lubricate the engine crankshaft
and the inner surface of the blade adapter with light
oil (or engine oil). Lubricating the bolt holes, bolts
and inner surface of the nuts is also recommended.
The deck may be cleaned by tilting the mower and
scraping clean with a suitable tool (make certain the
spark plug wire is disconnected).
ENGINE
Refer to the separate engine manual for engine
maintenance instructions.
Blade
Adaptor
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and
follow instructions carefully.
Blade
Service air cleaner every 25 hours under normal
conditions. Clean every few hours under extremely
dusty conditions. Poor engine performance and
flooding usually indicates that the air cleaner should
be serviced. To service the air cleaner, refer to the
separate engine manual packed with your unit.
Blade Bell
Support
Hex Bolt
The spark plug should be cleaned and the gap
reset once a season. Spark plug replacement is
recommended at the start of each mowing season;
check engine manual for correct plug type and gap
specifications.
Figure 15

tabs in the holes of the blade and insert the hex
bolt. Tighten the hex bolt to the torque listed in the
“Blade Mounting Torque” section below.
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area)
clean to permit proper air circulation which is
essential to engine performance and life. Be certain
to remove all grass, dirt and combustible debris
from muffler area.
SECTION 12: OFF-SEASON STORAGE
The following steps should be taken to prepare lawn
mower for storage.
4. Store mower in a dry, clean area. Do not store
next to corrosive materials, such as fertilizer.
1. Clean and lubricate mower thoroughly as
described in the lubrication instructions.
