SECTION 1: IMPORTANT SAFE OPERATION PRACTICES
WARNING: THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF NOT
FOLLOWED, COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF YOURSELF AND
OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE ATTEMPTING TO OPERATE
YOUR LAWN MOWER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSONAL
INJURY. WHEN YOU SEE THIS SYMBOL, HEED ITS WARNING.
DANGER: Your lawn mower was built to be operated according to the rules for safe operation in this
manual. As with any type of power equipment, carelessness or error on the part of the operator can result
in serious injury. This lawn mower is capable of amputating hands and feet and throwing objects. Failure to
observe the following safety instructions could result in serious injury or death.
1. GENERAL OPERATION
• Read this owner’s guide 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 it for 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.
• Thoroug hly inspect the ar ea where the equipm ent 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 a t least 75 f eet from th e mower whi le it is in
operation.
• 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.
• 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 a unit in bare feet, sandals, or sneakers.
• 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 when the mower is pulled over
the foot during a fall. 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. Be sure 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.
• Disengage the self-propelled mechanism or drive
clutch on units so equipped before starting the
engine.
• 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 w hen released.
• Never operate the mower in wet grass. Always be
sure of your footing. A slip and fall can cause serious
personal in jury. Keep a firm hold on the ha ndle and
walk, never run. Mow only in daylight or in good
artificial light.
• 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 troubl e.
• 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.
• Never operate mower without proper guards, grass
catcher, plates or other safety protective devices in
place.
• 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
instructi ons provided with the approved accessory.
• If situations occur which are not covered in this
manual, use care and good judgment. Contact your
dealer for assistance.
• Do not adjust throttle control with the engine running.
2. SLOPE OPERATION
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 grea ter than 15 degrees
as shown on the slope gauge, do not operate this mower.
3
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.
DO NOT:
• Do not mow near drop-offs, ditches or embankments.
The operator could loose 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.
3. CHILDREN
Tragic acc idents can occur if the oper ator is not alert to the
presence of children. Children are often attracted to the
mower and the mowing activity. Neve r 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.
• Never allow children under age 14 to operate the
mower.
• Use extreme care when approaching blind corners,
shrubs, tr ees, or other ob jects t hat ma y obscure your
vision of a child or hazard.
4. 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.
• 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.
• 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.
• Check the blade and engine mounting bolts at
frequent intervals for proper tightness. Also, visually
inspect blade for damage (e.g., bent, cracked).
Replace with blade which meets original equipment
specifications.
• Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.
• Never tamper with safety devices. Check their proper
operation regularly.
• 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.
• 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.
• 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 setting or
overspeed the engine. Excess ive engine speeds are
dangerous.

SECTION 6: OPERATING YOUR LAWN MOWER
Keep hands and feet away from the chute area on the
cutting deck. See safety labels on page 4.
The operation of any lawn mower can result in foreign
objects being thrown into the eyes, which can result in
severe eye damage. Always wear safety glasses or eye
shields. We recommend wide v ision sa fety ma sk for
over spectacles or standard safety glasses.
NOTE: For best results rais e the cutti ng posi ti on unt il it
is determined which hei ght is best for your lawn. See
Cutting Height Adjustment section.
NOTE: If you encounter any problems, refer to the
Trouble Shooting Guide for helpful information.
Stop Engine And Blade
• Release the blade control handle to stop the engine
and blade.
WARNING: The blade continues to rotate
for a few seconds after the engine is shut
off. Do not touch the blade in any way
while it is still rotating.
Gas And Oil Fill-Up
Service the engine with gasoline and oil as instructed in
the separate engine manual. Read instructions
carefully.
WARNING: Never fill fuel tank indoors,
with engine running or until the engine ha s
been allowed to cool for at least two
minutes after running.
Before Starting
• Attach spark plug wire to spark plug. If equipped
with a rubber boot, make certain the metal loop on
the end of the spark plug wire (inside the rubber
boot) is fastened securely over the metal tip on the
spark plug.
To Start Engine and Engage Blade
• Prime engine as instructed in the engine manual.
• Standing behind the unit, depress the blade control
handle and hold it against the upper handle.
• Grasp starter handle and pull rope out slowly until
engine reaches 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.
Keep a firm grip on starter handle. Return it slowly
to the rope guide.
• Disconnect the spark plug wire and ground it
against the engine to prevent accidental starting
while equipment is unattended.
Using Y our Rotary Mower
• Be sure that lawn is clear of stones, sticks, wire, or
other obj ects w hich could damage lawn m ower 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 yo u to slip and fa ll. New gras s, thick
grass or wet grass may require a narrower cut.
Speed of the mower should be adjusted to the
condition of the lawn.
• When using the side-discharge mower, 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 healthier lawn, always cut off one-third or less
of the total length of the grass. Lawn should be cut
in the fall as long as there is growth.
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 dama ge 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 11
• 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.
• 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 tes t of bal ance.

• Before reinstalling the blade and the blade adapter
to the uni t, lu bricat e th e eng ine cr anksha ft 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.
To Reinstall Blade:
• Be sure to install the blade with the side of the
blade marked “Bottom” (or with part number) facing
the ground when the mower is in the operating
position.
• Be certain the blade is aligned with and seated onto
the blade adapter flanges.
• Place blade bell support on blade. Make sure the
notches on the blade bell support are aligned with
the small hol e in the blade .
• Replace hex bo lt.
• Tighten to torque: 450 in. lbs. min., 600 in. lbs. max.
• To ensure safe operation of mower, check all nuts
and bolts periodically for correct torque.
Deck Maintenance
• 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 prevent proper mulching.
• The deck may be cleaned by tilting the mower and
scraping clean with a suitable tool (make certain the
spark plug wire is disconnected).
NOTE: We do not recommend the use of pressure
washers or garden hose to clea n your unit. Th ey may
cause damage to electric components, spindles,
pulleys, bearings or the engine. The use of water will
result in shortened life and reduce serviceability.
Engine Maintenance
• Refer to the separate engine manual for all engine
maintenance instructions.
• Maintain ENGINE OIL as instructed in the engine
manual.
• 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 engine manual.
• 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.
• CLEAN the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area)
cleaned to permit proper air circulation which is
essential to engine performance and life. Be certain
to remove all grass, dirt and combustible debris
from muff ler area.
SECTION 10: OFF-SEASON STORAGE
The following steps should be taken to prepare lawn
mower for storage.
• Clean and lubricate mower thoroughly as described
in the lubrication instructions.
NOTE: We do not recommend the use of pressure
washers or garden hose to cl ean your unit. They may
cause damage to electric components, spindles,
pulleys, bearings or the engine. The use of water will
result in shortened life and reduce serviceability.
• Refer to engine manual for correct engine storage
instructions.
• Coat mower’s cutting blade with chassis grease to
prevent rusting.
• Store mower in a dry, clean area. Do not store next
to corrosive materials, such as fertilizer.
NOTE: When storing any type of power equipment in
an unventilated or metal sto rage shed, care shou ld be
