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.
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.

WARNING
Do not mow on inclines with a slope in excess of 15 degrees (a rise of approximately 2-1/2 feet every 10 feet). A riding mower
could overturn and cause serious injury. If operating a walk-behind mower on such a slope, it is extremely difficult to maintain
your footing and you could slip, resulting in serious injury.
Operate RIDING mowers up and down slopes, never across the face of slopes.
Operate WALK-BEHIND mowers across the face of slopes, never up and down slopes.
