operator can result in serious injury. This machine is capable of amputating fingers, hands,  
toes and feet and throwing objects. Failure to observe the following safety instructions  
could result in serious injury or death.  
6.  
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.  
General Operation  
1.  
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  
7.  
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.  
2.  
3.  
Be completely familiar with the controls and the proper use  
of this machine before operating it.  
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.  
8.  
9.  
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.  
4.  
5.  
Never allow children under 14 years of age to operate this  
machine. Children 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.  
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.  
10. 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.  
Only responsible individuals who are familiar with these  
rules of safe operation should be allowed to use this

12. A missing or damaged discharge cover can cause blade  
contact or thrown object injuries.  
27. When starting engine, pull cord slowly until resistance  
is felt, then pull rapidly. Rapid retraction of starter cord  
(kickback) will pull hand and arm toward engine faster than  
you can let go. Broken bones, fractures, bruises or sprains  
could result.  
13. 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.  
28. If situations occur which are not covered in this manual,  
use care and good judgement. Contact Customer Support  
for assistance or the name of the nearest service dealer.  
14. 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:  
Slope Operation  
Slopes are a major factor related to slip and fall accidents, which  
can result in severe injury. 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 machine on a sloped or  
hilly area. If the slope is greater than 15 degrees, do not mow it.  
a. Step back from mower to fully extend your arms.  
b. Be sure you are well balanced with sure footing.  
c. Pull the mower back slowly, no more than half way  
toward you.  
d. Repeat these steps as needed.  
Do:  
1.  
15. Do not operate the mower while under the influence of  
alcohol or drugs.  
Mow across the face of slopes; never up and down. Exercise  
extreme caution when changing direction on slopes.  
16. Do not engage the self-propelled mechanism on machines  
so equipped while starting engine.  
2.  
Watch for holes, ruts, rocks, hidden objects, or bumps  
which can cause you to slip or trip. Tall grass can hide  
obstacles.  
17. 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.  
3.  
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.  
18. 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.  
Do Not:  
1.  
2.  
3.  
Do not mow near drop-offs, ditches or embankments, you  
could lose your footing or balance.  
Do not mow slopes greater than 15 degrees as shown on  
the slope gauge.  
19. Mow only in daylight or good artificial light. Walk, never  
run.  
Do not mow on wet grass. Unstable footing could cause  
slipping.  
20. Stop the blade when crossing gravel drives, walks or roads.  
21. If the equipment should start to vibrate abnormally, stop  
the engine and check immediately for the cause. Vibration  
is generally a warning of trouble.  
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.  
22. 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 blade control is released.  
Never place any part of the body in the blade area until you  
are sure the blade has stopped rotating.  
1.  
Keep children out of the mowing area and under watchful  
care of a responsible adult other than the operator.  
2.  
3.  
Be alert and turn mower off if a child enters the area.  
Before and while moving backwards, look behind and  
down for small children.  
23. Never operate mower without proper trail shield, discharge  
cover, grass catcher, blade control handle or other safety  
protective devices in place and working. Never operate  
mower with damaged safety devices. Failure to do so can  
result in personal injury.  
4.  
Use extreme care when approaching blind corners,  
doorways, shrubs, trees, or other objects that may obscure  
your vision of a child who may run into the mower.  
5.  
6.  
Keep children away from hot or running engines. They can  
suffer burns from a hot muffler.  
24. Muffler and engine become hot and can cause a burn. Do  
not touch.  
Never allow children under 14 years of age to operate this  
machine. Children 14 and over should read and understand  
the instructions and safe operation practices in this manual  
and on the machine and be trained and supervised by an  
adult.  
25. Never attempt to make a wheel or cutting height  
adjustment while the engine is running.  
26. Only use parts and accessories made for this machine by  
the manufacturer. Failure to do so can result in personal  
injury.

3.  
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 manufacture’s (O.E.M.) blade only,  
listed in this manual. “Use of parts which do not meet the  
original equipment specifications may lead to improper  
performance and compromise safety!”  
Service  
Safe Handling Of Gasoline:  
1.  
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 clothes,  
which can ignite. Wash your skin and change clothes  
immediately.  
4.  
5.  
6.  
7.  
Mower blades are sharp and can cut. Wrap the blade 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 condition.  
2.  
3.  
Use only an approved gasoline container.  
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.  
Never tamper with safety devices. Check their proper  
operation regularly.  
After striking a foreign object, stop the engine, 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.  
4.  
5.  
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.  
8.  
9.  
Never attempt to make a wheel or cutting height  
adjustment while the engine is running.  
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.  
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 equipment manufacturer’s  
(O.E.M.) parts only, listed in this manual. “Use of parts  
which do not meet the original equipment specifications  
may lead to improper performance and compromise  
safety!”  
6.  
7.  
8.  
Extinguish all cigarettes, cigars, pipes and other sources  
of ignition.  
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.  
9.  
Never over fill fuel tank. Fill tank to no more than 1 inch  
below bottom of filler neck to provide for fuel expansion.  
10. Do not change the engine’s governor setting or over-speed  
the engine. The governor controls the maximum safe  
operating speed of the engine.  
10. Replace gasoline cap and tighten securely.  
11. Check fuel line, tank, cap, and fittings frequently for cracks  
or leaks. Replace if necessary.  
11. If gasoline is spilled, wipe it off the engine and equipment.  
Move machine to another area. Wait 5 minutes before  
starting engine.  
12. Do not crank engine with spark plug removed.  
12. Never store the machine or fuel container near an open  
flame, spark or pilot light as on a water heater, space  
heater, furnace, clothes dryer or other gas appliances.  
13. Maintain or replace safety and instruction labels, as  
necessary.  
14. Observe proper disposal laws and regulations. Improper  
disposal of fluids and materials can harm the environment.  
13. 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.  
Do not modify engine  
14. Allow machine to cool at least 5 minutes before storing.  
To avoid serious injury or death, do not modify engine in any  
way. Tampering with the governor setting can lead to a runaway  
engine and cause it to operate at unsafe speeds. Never tamper  
with factory setting of engine governor.  
General Service:  
1.  
Never run an engine indoors or in a poorly ventilated area.  
Engine exhaust contains carbon monoxide, an odorless  
and deadly gas.  
Notice Regarding Emissions  
2.  
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 prevent  
unintended starting.  
Engines which are certified to comply with California and federal  
EPA emission regulations for SORE (Small Off Road Equipment)  
are certified to operate on regular unleaded gasoline, and  
may include the following emission control systems: Engine  
Modification (EM) and Three Way Catalyst (TWC) if so equipped.
