ITS WARNING!  
This machine was built to be operated according to the safe operation  
practices 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 machine is capable of amputating fingers, hands, toes and feet and  
throwing debris. Failure to observe the following safety instructions could  
result in serious injury or death.  
WARNING  
CALIFORNIA PROPOSITION 65  
Engine Exhaust, some of its constituents, and certain vehicle components  
contain or emit chemicals known to State of California to cause cancer and  
birth defects or other reproductive harm.  
WARNING  
Your Responsibility—Restrict the use of this power machine to  
persons who read, understand and follow the warnings and instructions in  
this manual and on the machine.  
SAVE THESE INSTRUCTIONS!  
GENERAL OPERATION  
Wear sturdy, rough-soled work shoes and close-fitting slacks and shirts.  
Shirts and pants that cover the arms and legs and steel-toed shoes are  
recommended. Never operate this machine in bare feet, sandals, slippery or  
light-weight (e.g. canvas) shoes.  
Read this operator’s manual carefully in its entirety before attempting to  
assemble this machine. Read, understand, and follow all instructions on the  
machine and in the manuals before operation. Keep this manual in a safe  
place for future and regular reference and for ordering replacement parts  
Do not put hands or feet near rotating parts or under the cutting deck.  
Contact with blade can amputate fingers, hands, toes and feet.  
Be completely familiar with the controls and the proper use of this machine  
before operating it.  
A missing or damaged discharge cover can cause blade contact or thrown  
object injuries.  
This machine is a precision piece of power equipment, not a plaything.  
Therefore, exercise extreme caution at all times. This machine has been  
designed to perform one job: to mow grass. Do not use it for any other  
purpose.  
Many injuries occur as a result of the mower being pulled over the foot  
during a fall caused by slipping or tripping. Do not hold on to the mower if  
you are falling: release the handle immediately.  
Never allow children under 14 years of age to operate this machine. Children  
Never pull the mower back toward you while you are walking. If you must  
back the mower away from a wall or obstruction first look down and behind  
to avoid tripping and then follow these steps:  
14 and over should read and understand the instructions and safe operation  
practices in this manual and on the machine and should be trained and  
supervised by an adult.  
a. Step back from mower to fully extend your arms forward.  
b. Be sure you are well balanced with sure footing.  
Only responsible individuals who are familiar with these rules of safe  
operation should be allowed to use this machine.  
c. Pull the mower back slowly, no more than half way toward you.  
d. Repeat these steps as needed.  
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.  
Do not operate the mower while under the influence of alcohol or drugs.  
Do not engage the self-propelled mechanism on machines so equipped  
while starting engine.  
Plan your mowing pattern to avoid discharge of material toward roads,  
sidewalks, bystanders and the like. Also, avoid discharging material against  
a wall or obstruction, which may cause discharged material to ricochet back  
toward the operator.  
The blade control handle is a safety device. Never attempt to bypass its  
operation. Doing so makes the safety device inoperative and may result in  
personal injury through contact with the rotating blade. The blade control  
handle must operate easily in both directions and automatically return to the  
disengaged position when released.  
To help avoid blade contact or a thrown object injury, stay in operator zone  
behind handles and keep children, bystanders, helpers and pets at least 75  
feet from mower while it is in operation. Stop machine if anyone enters area.  
Never operate the mower in wet grass. Always be sure of your footing. A  
slip and fall can cause serious personal injury. If you feel you are losing your  
footing, release the blade control handle immediately and the blade will  
stop rotating within three seconds.  
Always wear safety glasses or safety goggles during operation and while  
performing an adjustment or repair to protect your eyes. Thrown objects  
which ricochet can cause serious injury to the eyes.  
Mow only in daylight or good artificial light. Walk, never run.  
Stop the blade when crossing gravel drives, walks or roads.

SERVICE  
Safe Handling of Gasoline:  
If situations occur which are not covered in this manual, use care and good  
judgement.  
To avoid personal injury or property damage use extreme care in handling  
gasoline. Gasoline is extremely flammable and the vapors are explosive.  
Serious personal injury can occur when gasoline is spilled on yourself or your  
SLOPE OPERATION  
Slopes are a major factor related to slip and fall accidents, which can result in severe clothes which can ignite. Wash your skin and change clothes immediately.

speed up when going downhill. Be prepared to maintain control of the machine.  
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 machine on  
a sloped or hilly area. If the slope is greater than 15 degrees, do not mow it.  
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.  
Remove gas-powered equipment from the truck or trailer and refuel it on  
the ground. If this is not possible, then refuel such equipment on a trailer  
with a portable container, rather than from a gasoline dispenser nozzle.  
Do:  
Mow across the face of slopes; never up and down to avoid loss of control.  
Exercise extreme caution when changing direction on slopes; turn uphill not  
down.  
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.  
Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you  
to slip or trip. Tall grass can hide obstacles.  
Extinguish all cigarettes, cigars, pipes and other sources  
of ignition.  
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 three (3)  
seconds.  
Never fuel machine indoors because flammable vapors will accumulate in  
the area.  
Never remove gas cap or add fuel while engine is hot or running. Allow  
engine to cool at least two minutes before refueling.  
Do Not:  
Never over-fill fuel tank. To allow for expansion of the fuel, do not fill above  
the bottom of the fuel tank neck.  
Do not mow near drop-offs, ditches or embankments, because you could  
lose your footing or balance.  
Replace gasoline cap and tighten securely.  
Do not mow slopes greater than 15 degrees as shown on the slope guide.  
Do not mow on wet grass. Unstable footing could cause slipping.  
If gasoline is spilled, wipe it off the engine and equipment. Move machine to  
another area. Wait 5 minutes before starting engine.
