SAFETY OPERATION
PREPARATION TO MOW
● Remove all debris or other objects that might be picked up and thrown
by the blades. Keep all bystanders away from the mowing area.
● DO NOT operate the Mower when barefoot or wearing open sandals.
Always wear appropriate footwear.
● CHECK the fuel before starting the engine. Do not fill the gasoline
tank indoors or when the engine is running. Wait until the engine has
been allowed to cool for several minutes before filling with gasoline.
Clean up any spilled gasoline before starting the engine.
● KEEP the Blade Drive Lever in the disengaged position and shift the
Transmission into neutral before starting the engine.
Never make a height adjustment or any other Mower adjustment while
the engine is running.
● NEVER operate the Mower in wet grass. Always be sure of your
footing; keep a firm hold on the handles and walk; never run.
● Do not smoke while handling gasoline.
● Fill the tank outdoors and up to approximately 1” (25 mm) below the
bottom of the filler neck.
● Keep all shields, safety devices, and decals in place. If a shield, safety
device, or decal is defective or damaged, repair or replace it before
operating. ALSO, CHECK ALL NUTS, BOLTS, AND SCREWS
FOR PROPER TIGHTNESS, TO ASSURE THE MOWER IS IN
SAFE OPERATING CONDITION.
● Know the controls and how to stop quickly.
● Do not allow children under fourteen years old to operate the mower.
Do not allow adults to operate the mower without proper instruction.
● The owner/user can prevent and is responsible for accidents or injuries
occurring to themselves, other people, or property.
OPERATING THE MOWER
● ALWAYS wear safety goggles or safety glasses with side shields
when operating the Mower.
● DO NOT change the Engine Governor setting or overspend the
engine.
● DO NOT put hands or feet near or under rotating parts. Keep clear of
the discharge opening at all times.
● Disengage the blades and wait for them to stop before crossing gravel
drives, walks, or roads.
● MOW only in daylight or in good artificial light.
Always run the Engine at the fast speed setting for best mowing
performance.
●If the cutting blades should strike a solid object or the equipment
should start to vibrate abnormally, stop the engine, disconnect the spark
plug wire, and check immediately for the cause. Vibration is generally a
warning of trouble. Check the mower for damaged or defective parts.
Repair any damage before starting the engine or operating the mower
deck. Be sure the blades are in good condition and the blade bolts are
tight.
● STOP the Engine whenever you leave the Mower or during cleaning,
repairing, or inspecting. Make certain the Blades and all moving parts
have stopped. Disconnect the spark plug wire and keep the wire away
from the plug to prevent accidental starting.
● MOW across the face of slopes; never up and down. Exercise
extreme caution when changing direction on slopes. Do not mow on
slopes (with an incline of more than 15°). Exceeding the maximum
safe operating angle may cause tipping and loss of Mower control.
●The discharge chute must always be installed and in the down position
except when the optional grass catcher or mulching shield is properly
installed. If the discharge area should plug, shut the engine off and wait
for all movement to stop before removing the obstruction.
●Do not touch the engine or muffler while the engine is running or a
short time after it has stopped. These areas could be hot enough to cause
a burn.
●The engine should be started with the neutral latches in the neutral lock
position, the blades disengaged, the transmission in neutral, and the
operator’s presence levers released.
●Do not run the engine in a confined area without adequate ventilation.
Exhaust fumes are hazardous and could possibly be deadly.
●Using the mower demands attention. To prevent loss of control:
A. Watch for holes or other hidden hazards.
B. Do not drive close to a drop-off, ditch, creek bank, or other hazard.
