1. GENERAL OPERATION

State of California to cause cancer, birth defects or other reproductive harm.

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.

• Read, understand, and follow all instructions in the
operator’s manual and on the machine before
starting. Keep this manual in a safe place for future
and regular reference and for ordering replacement
parts.

• Only allow responsible individuals familiar with the
instructions to operate the machine. Know controls
and how to stop the machine quickly.

• Do not put hands or feet under cutting deck or near
rotating parts.

• Clear the area of objects such as rocks, toys, wire,
etc., which could be picked up and thrown by the
blade. A small object may have been overlooked and
could be accidentally thrown by the mower in any
direction and cause injury to you or a bystander. To
help avoid a thrown objects injury, keep children,
bystanders and helpers at least 75 feet from the
mower while 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. Stop the blade(s) when crossing
gravel drives, walks or roads.

• Be sure the area is clear of other people before
mowing. Stop machine if anyone enters the area.

• Never carry passengers.

• Disengage blade(s) before shifting into reverse and
backing up. Always look down and behind before and
while backing.

• Be aware of the mower and attachment discharge
direction and do not point it at anyone. Do not operate
the mower without either the entire grass catcher or
the chute guard in place.

• Slow down before turning. Operate the machine
smoothly. Avoid erratic operation and excessive
speed.

Never leave a running machine unattended. Always
turn off blade(s), place transmission in neutral, set
park brake, stop engine and remove key before
dismounting.

Turn off blade(s) when not mowing.
Stop engine and wait until blade(s) comes to a

complete stop before (a) removing grass catcher or
unclogging chute, or (b) making any repairs, adjusting
or removing any grass or debris.

Mow only in daylight or good artificial light.
Do not operate the machine while under the influence

of alcohol or drugs.
Watch for traffic when operating near or crossing

roadways.
Use extra care when loading or unloading the

machine into a trailer or truck. This unit should not be
driven up or down a ramp onto a trailer or truck under
power, because the unit could tip over, causing
serious personal injury. The unit must be pushed
manually on a ramp to load or unload properly.

Never make a cutting height adjustment while engine
is running if operator must dismount to do so.

Wear sturdy, rough-soled work shoes and close-fitting
slacks and shirts. 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.

Check overhead clearance carefully before driving
under power lines, wires, bridges or low hanging tree
branches, before entering or leaving buildings, or in
any other situation where the operator may be struck
or pulled from the unit, which could result in serious
injury.

Disengage all attachment clutches, thoroughly
depress the brake pedal, and shift into neutral before
attempting to start engine.

• Your mower is designed to cut normal residential
grass of a height no more than 10". Do not attempt to
mow through unusually tall, dry grass (e.g., pasture)
or piles of dry leaves. Debris may build up on the
mower deck or contact the engine exhaust presenting
a potential fire hazard.

2. SLOPE OPERATION

Slopes are a major factor related to loss of control and tip­over accidents which can result in severe injury or death. All
slopes require extra caution. If you cannot back up the slope
or if you feel uneasy on it, do not mow it.

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° as shown
on the slope gauge, do not operate this unit on that area or
serious injury could result.

DO:

Mow up and down slopes, not across.
Remove obstacles such as rocks, limbs, etc.
Watch for holes, ruts or bumps. Uneven terrain could

overturn the machine. Tall grass can hide obstacles.
Use slow speed. Choose a low enough gear so that

you will not have to stop or shift while on the slope.
Always keep machine in gear when going down
slopes to take advantage of engine braking action.

Follow the manufacturer’s recommendations for
wheel weights or counterweights to improve stability.

Use extra care with grass catchers or other
attachments. These can change the stability of the
machine.

Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction.
Rapid engagement or braking could cause the front of
the machine to lift and rapidly flip over backwards
which could cause serious injury.

Avoid starting or stopping on a slope. If tires lose
traction, disengage the blade(s) and proceed slowly
straight down the slope.

DO NOT:

Do not turn on slopes unless necessary; then, turn
slowly and gradually downhill, if possible.

Do not mow near drop-offs, ditches or embankments.
The mower could suddenly turn over if a wheel is
over the edge of a cliff or ditch, or if an edge caves in.

Do not mow on wet grass. Reduced traction could
cause sliding.

Do not try to stabilize the machine by putting your foot
on the ground.

Do not use grass catcher on steep slopes.

3. CHILDREN

Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
machine and the mowing activity. Never assume that children
will remain where you last saw them.

Keep children out of the mowing area and in watchful
care of an adult other than the operator.

Be alert and turn machine off if children enter the
area.

Before and when backing, look behind and down for
small children.

Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere with

the safe machine operation.

Never allow children under 14 years old to operate
the machine. Children 14 years and over should only
operate machine under close parental supervision
and proper instruction.

Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure your
vision of a child or other hazard.

Remove key when machine is unattended to prevent

unauthorized operation.

4. SERVICE

Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the vapors
are explosive.

Use only an approved container.
Never remove fuel cap or add fuel with the engine

running. Allow engine to cool at least two minutes
before refueling.

Replace fuel cap securely and wipe off any spilled
fuel before starting the engine as it may cause a fire
or explosion.

Extinguish all cigarettes, cigars, pipes and other
sources of ignition.

Never refuel the machine indoors because fuel
vapors will accumulate in the area.

Never store the fuel container or machine inside
where there is an open flame or spark, such as a gas
hot water heater, space heater or furnace.

Never run a machine inside a closed area.
To reduce fire hazard, keep the machine free of

grass, leaves or other debris build-up. Clean up oil or
fuel spillage. Allow machine 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., excessive
wear, 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. Use all guards as
instructed in this manual.

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 restarting and operating the mower.

Grass catcher components are subject to wear,
damage and deterioration, which could expose
moving parts or allow objects to be thrown. For
your 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 blade(s).

Check brake operation frequently. Adjust and
service as required.

Muffler, engine and belt guards become hot during
operation and can cause a burn. Allow to cool
down before touching.

Do not change the engine governor settings or
overspeed the engine. Excessive engine speeds
are dangerous.

Observe proper disposal laws and regulations.
Improper disposal of fluids and materials can harm
the environment and the ecology.

Prior to disposal, determine the proper method to
dispose of waste from your local Environmental
Protection Agency. Recycling centers are
established to properly dispose of materials in an
environmentally safe fashion.

Use proper containers when draining fluids. Do not
use food or beverage containers that may mislead
someone into drinking from them. Properly dispose
of the containers immediately following the draining
of fluids.

DO NOT pour oil or other fluids into the ground,
down a drain or into a stream, pond, lake or other
body of water. Observe Environmental Protection
Agency regulations when disposing of oil, fuel,
coolant, brake fluid, filters, batteries, tires and other
harmful waste.

disconnect battery cables. Removing battery
from unit is recommended.

6. Store unit in a clean, dry area. Do not store next
to corrosive materials, such as fertilizer.
