chine if anyone enters the area.
•
Thoroughly inspect the area where the
equipment is to be used. Remove all stones,
sticks, wire, bones, toys and other foreign
objects which could be tripped over or
picked up and thrown by the blade. Thrown
objects can cause serious personal injury.
•
Plan your mowing pattern to avoid dis
charge of material toward roads, sidewalks,
bystanders and the like. Also, avoid dis
charging material against a wall or
obstruction which may cause discharged
material to ricochet back toward the opera
tor.
•
Always wear safety glasses or safety gog
gles during operation and while performing
an adjustment or repair to protect your
eyes. Thrown objects which ricochet can
cause serious injury to the eyes.

SLOPE OPERATION
Slopes are a major factor related to slip and
fall accidents which can result in severe in
jury. Operation on slopes requires extra
caution. If you feel uneasy on a slope, 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 degrees, do not mow it.
DO:
Mow across the face of slopes; never up
•
and down. Exercise extreme caution when
changing direction on slopes. Watch for
holes, ruts, bumps, rocks, or other hidden
objects which can cause you to slip or trip.
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 rotating within 3 seconds.
DO NOT:
Do not mow near drop-offs, ditches or em
•
bankments, you could lose your footing or
balance.
Do not mow slopes greater than 15 degrees
•
-
as shown on the slope gauge.
Do not mow on wet grass. Unstable 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. They do not understand the
dangers. Never assume that children will remain where you last saw them.
a) Keep children out of the mowing area
and under the watchful care of a responsible adult other than the operator.
b) Be alert and turn mower off if a child en-
ters the area.
c) Before and while moving backwards, look
behind and down for small children.
d) Use extreme care when approaching
blind corners, doorways, shrubs, trees, or
other objects that may obscure your vi
sion of a child who may run into the
mower.
e) Keep children away from hot or running
engines. They can suffer burns from a
hot muffler.
•
Never allow children under 14 years old to
operate a power mower. Children 14 years
old and over should read and understand
the operation instructions and safety rules in
this manual and should be trained and su
pervised by a parent.
SERVICE SAFE HANDLING OF GASOLINE:
•
To avoid personal injury or property damage
use extreme care in handling gasoline. Gas
oline is extremely flammable and the vapors
are explosive. Serious personal injury can
occur when gasoline is spilled on yourself

or your clothes which can ignite. Wash your
skin and change clothes immediately.
a) Use only an approved gasoline container.
b) Never fill containers inside a vehicle or on
a truck or trailer bed with a plastic liner.
Always place containers on the ground
away from your vehicle before filling.
c) When practical, remove gas-powered
equipment from the truck or trailer and
refuel it on the ground. If this is not possi
ble, then refuel such equipment on a
trailer with a portable container, rather
than from a gasoline dispenser nozzle.
d) Keep the nozzle in contact with the rim of
the fuel tank or container opening at all
times until fueling is complete. Do not
use a nozzle lock-open device.
e) Extinguish all cigarettes, cigars, pipes
and other sources of ignition.
f) Never fuel machine indoors.
g) Never remove gas cap or add fuel while
the engine is hot or running. Allow en
gine to cool at least two minutes before
refueling.
h) Never over fill fuel tank. Fill tank to no
more than ½ inch below bottom of filler
neck to provide space for fuel expansion.
i) Replace gasoline cap and tighten se-
curely.
j) If gasoline is spilled, wipe it off the en-
gine and equipment. Move unit to
another area. Wait 5 minutes before start-
ing the engine.
k) Never store the machine or fuel container
inside where there is an open flame,
spark or pilot light as on a water heater,
space heater, furnace, clothes dryer or
other gas appliances.
l) To reduce fire hazard, keep machine free
of grass, leaves, or other debris build-up.
Clean up oil or fuel spillage and remove
any fuel soaked debris.
m) Allow machine to cool at least 5 minutes
before storing.
GENERAL SERVICE:
Never run an engine indoors or in a poorly
•
ventilated area. Engine exhaust contains car
bon monoxide, an odorless and deadly gas.
Before cleaning, repairing, or inspecting,
•
make certain the blade and all moving parts
have stopped. Disconnect the spark plug
wire and ground against the engine to pre
vent unintended starting.
Check the blade and engine mounting bolts
-
•
at frequent intervals for proper tightness.
Also, visually inspect blade for damage
(e.g., bent, cracked, worn) Replace blade
with the original equipment manufacturer’s
(O.E.M.) blade only, listed in this manual.
“Use of parts which do not meet the original
equipment specifications may lead to im
proper performance and compromise
safety!”
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 condi
tion.
Never tamper with safety devices. Check
•
their proper operation regularly.
After striking a foreign object, stop the en-
•
gine, disconnect the spark plug wire and
ground against the engine. Thoroughly inspect the mower for any damage. Repair
the damage before starting and operating
the mower.
•
Grass catcher components, discharge cover,
and trail shield are subject to wear and
damage which could expose moving parts
or allow objects to be thrown. For safety
protection, frequently check components
and replace immediately with original equip
ment manufacturer’s (O.E.M.) parts only,
listed in this manual. “Use of parts which do
not meet the original equipment specifica
tions may lead to improper performance
and compromise safety!”
•
Do not change the engine governor setting
or overspeed the engine. The governor con
trols the maximum safe operating speed of
the engine.
•
Maintain or replace safety and instruction la
bels, as necessary.
•
Observe proper disposal laws and regula
tions. Improper disposal of fluids and
materials can harm the environment.
