GENERAL SAFETY PROCEDURES
For any questions regarding the hazard and safety notices listed in this manual or on the product,
please call [phone] Mon-Fri 9-5 EST before using the engine.
DANGER: CARBON MONOXIDE
Using an engine indoors CAN KILL YOU IN MINUTES. Engine exhaust contains carbon
monoxide (CO). This is a poison gas you cannot see or smell. If you can smell the engine exhaust, you
are breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.
NEVER use an engine inside homes, garages, crawlspaces, or other partly enclosed areas. Deadly
levels of carbon monoxide can build up in these areas. Using a fan, or opening windows and/or doors
will NOT properly vent CO nor supply adequate fresh air. ONLY use an engine outside and far away
from windows, doors, and vents. These openings can pull in engine exhaust.
Even if you use an engine correctly, CO may leak into the home. ALWAYS use a battery-powered or
battery-backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the engine has
been running, move to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide
poisoning.
WARNING: The exhaust from this product contains chemicals known to the State of California to
cause cancer, birth defects, or other reproductive harm.
WARNING: This engine may emit highly flammable and explosive gasoline vapors, which can
cause severe burns or even death if ignited. A nearby open flame can lead to explosion even if it isn’t
directly in contact with gasoline.
• Do not operate near an open flame.
• Do not smoke near the engine.
• Always operate on a firm, level surface.
• Always turn engine off before refueling. Allow engine to cool for at least 2 minutes before
removing fuel cap. Loosen cap slowly to relieve pressure in tank.
• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the
tank. Allow for expansion.
• Always check for spilled fuel before operating.
• Empty fuel tank and carburetor bowl before storing or transporting the engine.
WARNING: This engine produces heat when running. Temperatures near exhaust can exceed 1500F
(650C).
Do not touch hot surfaces. Pay attention to warning labels on the engine identifying hot parts of the
machine.
Allow engine to cool down after use before touching engine or areas of the engine that become hot
during use.
CAUTION: Misuse of this engine can damage it or shorten its life.
Only use engine for its intended purposes.

IMPORTANT SAFETY INSTRUCTIONS
This machine is capable of amputating hands and feet and throwing objects. Failure to observe the
following safety instructions could result in serious injury or death.
I.General Operation
1. Read, understand, and follow instructions and warnings in this manual and on the machine, engine
and attachments.
2. Only allow operators, who are responsible, trained, familiar with the instructions, and physically
capable to operate the machine.
3. Do not carry passengers and keep bystanders away.
4. Do not operate the machine while under the influence of alcohol or drugs.
5. Follow the manufacturer’s recommendation for wheel weights or counterweights.
II. PREPARATION BEFORE OPERATING
1. Clear the operating area of any objects which could be thrown by or interfere with operation of the
machine
2. Keep the area of operation clear of all bystanders, particularly small children. Stop the machine
and attachment(s) if anyone enters the area.
3. Do not operate the machine without the entire grass catcher, discharge chute, or other safety
devices in place and functioning properly. Check frequently for signs of wear or deterioration and
replace as needed.
4. Wear appropriate personal protective equipment such as safety glasses, hearing protection, and
footwear.
III. OPERATING
1. Only operate the engine in well ventilated areas. Exhaust gases contain carbon monoxide, a
deadly poison.
2. Only operate the machine in daylight or good artificial light.
3. Avoid holes, ruts, bumps, rocks, or other hidden hazards. Uneven terrain could overturn the
machine, or cause operator to lose their balance or footing.
4. Do not put hands or feet near rotating parts or under the machine. Keep clear of the discharge
opening at all times.
5. Do not direct discharge material toward anyone. Avoid discharging material against a wall or
obstruction. Material may ricochet back toward the operator. Stop the blade(s) when crossing
gravel surfaces.
6. Do not leave a running machine unattended. Always park on level ground, disengage the
attachment, set parking brake, and stop engine.
7. Do not mow in reverse unless absolutely necessary. Always look down and behind before and
while backing.
IV. CHILDREN SPECIFIC
1. 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 children will remain
where you last saw them.
2. Keep children out of the operating area and under the watchful care of a responsible adult other
than the operator.

7
V. SLOPE SPECIFIC
Slopes are a major factor related to accidents. Operation on slopes requires extra caution.
1. Travel in the manufacturer recommended direction on slopes. Use caution while operating near
drop offs.
2. Avoid mowing wet grass. (Poor footing could cause a slip and fall accident.)
3. Do not operate machine under any condition where traction, steering, or stability is in question.
Tires could slide even if the wheels are stopped.
4. Always keep the machine in gear when going down slopes. Do not coast downhill.
5. Avoid starting and stopping on slopes. Avoid making sudden changes in speed or direction. Make
turns slowly and gradually.
6. Use extra care while operating machine with a grass catcher or other attachment(s). They can
affect the stability of the machine.
VI. FIRE AND FUEL SPECIFIC
1. Extinguish all cigarettes, cigars, pipes and other sources of ignition.
2. Use only an approved fuel container.
3. Do not remove fuel cap or add fuel with the engine running or while hot.
4. Do not refuel indoors or in enclosed spaces
5. Do not store the machine or fuel container, or refuel, where there is an open flame, spark, or pilot
light such as on a water heater or other appliance.
6. If fuel is spilled, do not attempt to start the engine and avoid creating any source of ignition until
fuel vapors have dissipated.
7. To help prevent fires: keep machine free of grass, leaves, or other debris build up; clean up oil or
fuel spillage and remove any fuel soaked debris; allow machine to cool before storing.
8. Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.
VII. HAULING
1. Use full width ramps for loading and unloading a machine for transport.
VIII. SERVICE
1. Keep machine in good working order. Replace worn or damaged parts.
2. Use caution when servicing blades. Wrap the blade(s) or wear gloves. Replace damaged blades.
Do not repair or alter blade(s)
3. Machines with hydraulic pumps, hoses, or motors; and/or diesel injection systems:
WARNING: Fluid escaping under pressure may have sufficient force to penetrate skin and cause
serious injury. If fluid is injected into the skin, seek immediate medical attention. Keep body and
hands away from pin holes or nozzles that eject fluid under high pressure. If a leak occurs, have
the machine immediately serviced by a trained technician.
4. If equipped, disconnect spark plug wire(s) before making any repairs.
