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.

Mow only in daylight or 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 trouble.

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 instructions 
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. Telephone 1-800-800-
7310 for the name of your nearest dealer.

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 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.

Do not:

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 in this 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.

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,
