Trimmer Safety
• Read, understand, and follow instructions and
warnings in this manual and on the machine, engine
and attachments.
• Know the controls and the proper use of the machine
before starting.
• The equipment should only be used in good weather
conditions and with clear visibility.
• To prevent injury to others, keep people at least 50
feet (15 meters) away from the working area during
operation.
• DO NOT touch the cutting head or blade in motion.
• Keep firm footing and balance. Do not over-reach.
Keep cutting attachment below waist level. Keep all
parts of your body away from the rotating cutting
attachment and hot surfaces.
• NEVER use the unit without the blade guard securely
in place.
• Do not strike objects that may cause harm or damage
to the unit.
• Always wear eye protection and protective clothing.
Always wear the safety glasses provided with the unit.
Protect yourself when operating unit by wearing safety
glasses, a dust mask, long pants, ear protection, and
substantial footwear.
• Clear the working area. Objects thrown by the trimmer
can cause serious injury. Before operating the trimmer,
carefully inspect the area and remove any broken
glass, pieces of wire, and other loose objects.
• The cutting attachment may be spinning during
carburetor adjustments. Wear protective equipment
and observe all safety instructions. For units equipped
with a clutch, be sure the cutting attachment stops
turning when the engine idles. When the unit is turned
off, make sure the attachment has stopped before the
unit is set down.
• A coasting blade can cause injury while it continues to
spin after the engine is stopped or throttle trigger is
released. Maintain proper control until the blade has
completely stopped rotating.
Safe Handling of Gasoline
To avoid personal injury or property damage, use extreme
care in handling gasoline. Gasoline is extremely flammable
and the vapors are explosive.
• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
• Use only an approved fuel container.
• DO NOT fill fuel containers inside a vehicle or on a
truck or trailer with a plastic liner. Always place the
containers on the ground away from the vehicle before
filling.
• 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.
• DO NOT refuel the machine indoors.
• DO NOT remove fuel cap or add fuel with the engine
running. Allow the engine to cool before refueling.
• Remove gas-powered equipment from the vehicle
or trailer and refuel it on the ground. If this is not
possible, then refuel equipment using a portable
container, rather than a gasoline dispenser nozzle.
• Never overfill a fuel tank. Replace fuel cap and tighten
securely.
• DO NOT store the machine or fuel container inside
where there is an open flame, spark or pilot light such
as on a water heater or other appliance.
• If fuel is spilled on clothing, change clothing
immediately.
Protection for Children, Bystander, and Pets
Tragic accidents can occur if the operator is not alert to the
presence of children, bystanders, and pets. Children are
often attracted to the machine and the trimming activity.
Never assume that children will remain where you last saw
them.
• Keep children out of the trimming area and under the
watchful care of a responsible adult.
• Clear the area to be cut before each use. Remove all
objects such as broken glass, nails, wires, or string,
which could be thrown or become entangled in the
cutting attachment.
• Clear the area of children, bystanders, and pets.
• Keep all children, bystanders outside of a 50 ft (15 m)
radius.
• Bystanders should be encouraged to wear eye
protection.
• Do not allow children or others to use the equipment
or attachments. They can be seriously injured.
• Allow only responsible persons who understand these
instructions to operate this equipment.
• Use extra care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.

Maintenance Safety
• Keep engine free of grass, leaves or excess grease to
reduce fire hazard and engine overheating.
• When draining fuel tank, drain fuel into an approved
container outdoors and away from open flame.
• Always provide adequate ventilation when running
engine. Exhaust gases contain carbon monoxide, an
odorless and deadly poison.
• Service engine and make adjustments only when
engine is stopped. Remove spark plug wire from spark
plug and secure wire away from spark plug.
• DO NOT change engine governor speed settings or
overspeed engine.
• DO NOT test for spark with spark plug removed.
Transporting and Storage Safety
• DO NOT store equipment or fuel container inside
where fumes may reach an open flame, spark or
pilot light such as in a water heater, furnace, clothes
dryer or other gas appliance. Allow engine to cool
before storing equipment in an enclosure. Store
fuel container out of the reach of children in a well
ventilated, unoccupied building.
• Do not stand the unit unsecured or unattended in the
vertical position. Do not store in the vertical position.
• Hand carry the unit in the horizontal position with the
engine stopped and the muffler away from your body.
Ensure the blade is well clear of people and property.
• Allow the engine to cool before transporting or storing
the unit.
• Empty the fuel tank after each use and before storing
the unit.

Choke Lever
The choke lever (Figure 1) opens and closes the choke
valve. The CLOSED position enriches the fuel mixture for
starting a cold engine. The OPEN position provides the
correct fuel mixture for operation after starting, and for
restarting a warm engine.
Ignition Switch
The ignition switch (A, Figure 2) controls the ignition
system. The ignition switch must be in the ON position for
the engine to start and run. Moving the ignition switch to
the STOP position stops the engine.
Throttle Control Switch
The throttle control switch (A, Figure 3) controls engine
speed. Pulling the throttle trigger toward the control handle
grip increases engine speed. Releasing the throttle trigger
reduces engine speed.
Pressing the priming bulb (Figure 4) pumps fuel from the
fuel tank to the carburetor. This procedure is necessary for
starting the engine. Prime the clear fuel bulb at the bottom
of the carburetor until it becomes hard and full of fuel.
