SECTION 3: IMPORTANT SAFE OPERATION PRACTICES  
WARNING: THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF  
NOT FOLLOWED, COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF  
YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL  
BEFORE ATTEMPTING TO OPERATE YOUR LAWN MOWER. FAILURE TO COMPLY WITH  
THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOL,  
HEED ITS WARNING.  
WARNING:  
The Engine Exhaust from this product contains chemicals known to  
the State of California to cause cancer, birth defects or other reproductive harm.  
DANGER: Your lawn mower was built to be operated according to the rules for safe operation 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 lawn mower is capable of amputating hands and feet and throwing  
objects. Failure to observe the following safety instructions could result in serious injury or death.  
1. GENERAL OPERATION  
• Read, understand, and follow all instructions in the  
• Never leave a running machine unattended. Always  
turn off blade(s), place transmission in neutral, set  
park brake, stop engine and remove key before  
dismounting.  
operator’s manual and on the machine before  
starting. Keep this manual in a safe place for future  
and regular reference and for ordering replacement  
parts.  
• Turn off blade(s) when not mowing.  
• Only allow responsible individuals familiar with the  
instructions to operate the machine. Know controls  
and how to stop the machine quickly.  
• Stop engine and wait until blade(s) comes to a  
complete stop before (a) removing grass catcher or  
unclogging chute, or (b) making any repairs,  
adjusting or removing any grass or debris.  
• Do not put hands or feet under cutting deck or near  
rotating parts.  
• Mow only in daylight or good artificial light.  
• Clear the area of objects such as rocks, toys, wire,  
etc., which could be picked up and thrown by the  
blade. A small object may have been overlooked  
and could be accidentally thrown by the mower in  
any direction and cause injury to you or a  
bystander. To help avoid a thrown objects injury,  
keep children, bystanders and helpers at least 75  
feet from the mower while it is in operation. Always  
wear safety glasses or safety goggles during  
operation or while performing an adjustment or  
repair, to protect eyes from foreign objects. Stop  
the blade(s) when crossing gravel drives, walks or  
roads.  
• Do not operate the machine while under the  
influence of alcohol or drugs.  
• Watch for traffic when operating near or crossing  
roadways.  
• Use extra care when loading or unloading the  
machine into a trailer or truck. This unit should not  
be driven up or down a ramp onto a trailer or truck  
under power, because the unit could tip over,  
causing serious personal injury. The unit must be  
pushed manually on a ramp to load or unload  
properly.  
• Never make a cutting height adjustment while  
engine is running if operator must dismount to do  
so.  
• Be sure the area is clear of other people before  
mowing. Stop machine if anyone enters the area.  
• Never carry passengers.  
• Wear sturdy, rough-soled work shoes and close-  
fitting slacks and shirts. Do not wear loose fitting  
clothes or jewelry. They can be caught in moving  
parts. Never operate a unit in bare feet, sandals, or  
sneakers.  
• Disengage blade(s) before shifting into reverse and  
backing up. Always look down and behind before  
and while backing.  
• Be aware of the mower and attachment discharge  
direction and do not point it at anyone. Do not  
operate the mower without either the entire grass  
catcher or the chute guard in place.  
• Check overhead clearance carefully before driving  
under power lines, wires, bridges or low hanging  
tree branches, before entering or leaving buildings,  
or in any other situation where the operator may be  
struck or pulled from the unit, which could result in  
serious injury.  
• Slow down before turning. Operate the machine  
smoothly. Avoid erratic operation and excessive  
speed.

• Disengage all attachment clutches, thoroughly  
depress the brake pedal, and shift into neutral  
before attempting to start engine.  
DO NOT:  
• Do not turn on slopes unless necessary; then, turn  
slowly and gradually downhill, if possible.  
• Your mower is designed to cut normal residential  
grass of a height no more than 10". Do not attempt  
to mow through unusually tall, dry grass (e.g.,  
pasture) or piles of dry leaves. Debris may build up  
on the mower deck or contact the engine exhaust  
presenting a potential fire hazard.  
• Do not mow near drop-offs, ditches or  
embankments. The mower could suddenly turn  
over if a wheel is over the edge of a cliff or ditch, or  
if an edge caves in.  
• Do not mow on wet grass. Reduced traction could  
cause sliding.  
• Do not try to stabilize the machine by putting your  
foot on the ground.  
2. SLOPE OPERATION  
Slopes are a major factor related to loss of control and tip-  
over accidents which can result in severe injury or death.  
All slopes require extra caution. If you cannot back up the  
slope or if you feel uneasy on it, do not mow it.  
For your safety, use the slope gauge included as part of  
your tractor’s Operator’s Manual to measure slopes before  
operating this unit on a sloped or hilly area. If the slope is  
greater than 15° as shown on the slope gauge, do not  
operate this unit on that area or serious injury could result.  
• Do not use grass catcher on steep slopes.  
3. CHILDREN  
Tragic accidents can occur if the operator is not alert to the  
presence of children. Children are often attracted to the  
machine and the mowing activity. Never assume that chil-  
dren will remain where you last saw them.  
• Keep children out of the mowing area and in  
watchful care of an adult other than the operator.  
DO:  
• Be alert and turn machine off if children enter the  
area.  
• Mow up and down slopes, not across.  
• Remove obstacles such as rocks, limbs, etc.  
• Before and when backing, look behind and down  
for small children.  
• Watch for holes, ruts or bumps. Uneven terrain  
could overturn the machine. Tall grass can hide  
obstacles.  
• Never carry children, even with the blades off. They  
may fall off and be seriously injured or interfere with  
the safe machine operation.  
• Use slow speed. Choose a low enough gear so that  
you will not have to stop or shift while on the slope.  
Always keep machine in gear when going down  
slopes to take advantage of engine braking action.  
• Never allow children under 14 years old to operate  
the machine. Children 14 years and over should  
only operate machine under close parental  
supervision and proper instruction.  
• Follow the manufacturer’s recommendations for  
wheel weights or counterweights to improve  
stability.  
• Use extra care when approaching blind corners,  
shrubs, trees or other objects that may obscure  
your vision of a child or other hazard.  
• Use extra care with grass catchers or other  
attachments. These can change the stability of the  
machine.  
• Remove key when machine is unattended to  
prevent unauthorized operation.  
• Keep all movement on the slopes slow and  
gradual. Do not make sudden changes in speed or  
direction. Rapid engagement or braking could  
cause the front of the machine to lift and rapidly flip  
over backwards which could cause serious injury.  
4. SERVICE  
• Use extreme care in handling gasoline and other  
fuels. They are extremely flammable and the  
vapors are explosive.  
• Avoid starting or stopping on a slope. If tires lose  
traction, disengage the blade(s) and proceed slowly  
straight down the slope.  
• Use only an approved container.  
• Never remove fuel cap or add fuel with the engine  
running. Allow engine to cool at least two minutes  
before refueling.

• Replace fuel cap securely and wipe off any spilled  
fuel before starting the engine as it may cause a  
fire or explosion.  
• Grass catcher components are subject to wear,  
damage and deterioration, which could expose  
moving parts or allow objects to be thrown. For  
your  
safety  
protection,  
frequently  
check  
• Extinguish all cigarettes, cigars, pipes and other  
sources of ignition.  
components and replace with manufacturer’s  
recommended parts when necessary.  
• Never refuel the machine indoors because fuel  
vapors will accumulate in the area.  
• Mower blades are sharp and can cut. Wrap the  
blade(s) or wear gloves and use extra caution  
when servicing blade(s).  
• Never store the fuel container or machine inside  
where there is an open flame or spark, such as a  
gas hot water heater, space heater or furnace.  
• Check brake operation frequently. Adjust and  
service as required.  
• Never run a machine inside a closed area.  
• Muffler, engine and belt guards become hot during  
operation and can cause a burn. Allow to cool  
down before touching.  
• To reduce fire hazard, keep the machine free of  
grass, leaves or other debris build-up. Clean up oil  
or fuel spillage. Allow machine to cool at least 5  
minutes before storing.  
• Do not change the engine governor settings or  
overspeed the engine. Excessive engine speeds  
are dangerous.  
• Before cleaning, repairing or inspecting, make  
certain the blade and all moving parts have  
stopped. Disconnect the spark plug wire, and keep  
the wire away from the spark plug to prevent  
accidental starting.  
• Observe proper disposal laws and regulations.  
Improper disposal of fluids and materials can harm  
the environment and the ecology.  
• Prior to disposal, determine the proper method to  
dispose of waste from your local Environmental  
Protection Agency. Recycling centers are  
established to properly dispose of materials in an  
environmentally safe fashion.  
• Check the blade and engine mounting bolts at  
frequent intervals for proper tightness. Also,  
visually inspect blade for damage (e.g., excessive  
wear, bent, cracked). Replace with blade which  
meets original equipment specifications.  
• Use proper containers when draining fluids. Do not  
use food or beverage containers that may mislead  
someone into drinking from them. Properly dispose  
of the containers immediately following the draining  
of fluids.  
• Keep all nuts, bolts and screws tight to be sure the  
equipment is in safe working condition.  
• Never tamper with safety devices. Check their  
proper operation regularly. Use all guards as  
instructed in this manual.  
• DO NOT pour oil or other fluids into the ground,  
down a drain or into a stream, pond, lake or other  
body of water. Observe Environmental Protection  
Agency regulations when disposing of oil, fuel,  
coolant, brake fluid, filters, batteries, tires and other  
harmful waste.  
• After striking a foreign object, stop the engine,  
remove the wire from the spark plug and thoroughly  
inspect the mower for any damage. Repair the  
damage before restarting and operating the mower.  
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.  
DO NOT OPEN THIS  
COVER UNLESS THE  
ENGINE IS SHUT OFF.
