• Mow only in daylight or good artificial light.
• Do not operate the machine while under
the influence of alcohol or drugs.
• Never operate machine in wet grass.
Always be sure of your footing: keep a
firm hold on the handle; walk, never run.
• Disengage the drive system, if so equipped,
before starting the engine (motor).
• If the equipment should start to vi brate
abnormally, stop the engine (motor) and
check immediately for the cause. Vibra-
tion is generally a warning of trouble.
• Always wear eye protection when op er-
at ing machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
• When loading or unloading this ma-
chine, do not exceed the maximum
recommended operation angle of 15°.
• Wear proper Personal Protective Equip-
ment (PPE) while operating this machine,
including (at a minimum) sturdy footwear,
eye protection, and hearing protection. Do
not mow in shorts or open toed footwear.
Always let someone know you are outside
mowing.
III. SLOPE OPERATION
Slopes are a major factor related to slip &
fall accidents, which can result in severe
injury. All slopes require extra caution. If
you feel uneasy on a slope, do not mow it.
DO:
• Mow across the face of slopes: nev er
up and down. Exercise extreme caution
when changing direction on slopes.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, bumps or hidden ob-
jects. Uneven terrain could cause a slip and
fall accident. Tall grass can hide obstacles.
DO NOT:
• Do not mow near drop-offs, ditches or
embankments. You could lose your foot-
ing or balance.
• Do not mow on wet grass or excessively
steep slopes. Poor footing could cause
a slip and fall accident.
IV. SAFE HANDLING OF GASOLINE
To avoid personal injury or property dam-
age, use extreme care in handling gaso-
line. Gasoline is extremely flammable and
the vapors are explosive.
• Extinguish all cigarettes, cigars, pipes
and other sources of ignition.
• Use only an approved container.
• Never remove gas cap or add fuel with
the engine running.
• Allow engine to cool before refueling.
• Never refuel the machine indoors.
• Never store the machine or fuel contain-
er where there is an open flame, spark
or pilot light such as a water heater or
on other appliances.
• Never fill containers inside a vehicle, on
a truck or trailer bed with a plastic liner.
Always place containers on the ground
away from your vehicle before filling.
• Remove gas-powered equipment from
the truck or trailer and refuel it on the
ground. If this is not possible, then
refuel such equipment with a portable
container, rather than from a gasoline
dispenser nozzle.
• 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.
• If fuel is spilled on clothing, change
clothing immediately.
• Never overfill fuel tank. Replace gas
cap and tighten securely.
V. GENERAL SERVICE
• Never run a machine inside a closed area.
• Never make adjustments or repairs with
the engine (motor) running. Dis con nect
the spark plug wire, and keep the wire
away from the plug to prevent ac ci den-
tal starting.
• Keep all nuts and bolts tight to be sure the
equipment is in safe working condition.
• Never tamper with safety devices. Check
their proper operation reg u lar ly. Never
do anything to interfere with the intended
function of a safety device or reduce the
protection provided by a safety device.
• Keep machine free of grass, leaves, or
other debris build-up. Clean oil or fuel spill-
age. Allow machine to cool before storing.
• Stop and inspect the equipment if you
strike an object. Repair, if nec es sary,
before restarting.
• Never attempt to make wheel height
adjustments while the engine is running.
• Grass catcher components are sub ject to
wear, dam age, and de te ri o ra tion, which
could expose moving parts or allow objects
to be thrown. Frequently check com po-
nents and replace with man u fac tur er’s
recommended parts, when necessary.
• Mower blades are sharp and can cut.
Wrap the blade(s) or wear gloves, and
use extra caution when ser vic ing them.
• Do not change the engine governor set-
ting or overspeed the engine.
• Maintain or replace safety and instruc-
tion labels, as necessary.
