GENERAL SAFETY RULES
WARNING!
Read and understand all instructions. Failure to follow
all instructions listed below, may result in electric shock,
fire and/or serious personal injury.
READ ALL INSTRUCTIONS
For safe operation, read and understand all instructions
before using this product. Follow all safety instructions.
Failure to follow all safety instructions listed below, can result
in serious personal injury.
Do not allow children or untrained individuals to use this
unit.
Never let anyone use the machine who has not received
adequate instructions in the machine’s proper use. This
applies to rentals as well as privately owned units and also
to the power head it is attached to.
Al w a y s wear s a f e t y glasses w i t h side s h i e l d s.
Everyday glasses have only impact resistant lenses. They
are NOT safety glasses. Following this rule will reduce the
risk of eye injury.
Product users on United States Forest Service land, and in
some states, must comply with fire prevention regulations.
This product is equipped with a spark arrestor; however,
other user requirements may apply. Check with your federal,
state, or local authorities.
Wear heavy, long pants, boots, and gloves. Do not wear
loose fitting clothing, short pants, or go barefoot. Do not
wear jewelry of any kind. Wear hearing protection.
Heavy protective clothing may increase operator fatigue,
which could lead to heat stroke. During weather that is hot
and humid, heavy work should be scheduled for early morning
or late afternoon hours when temperatures are cooler.
Never operate this unit on the operator’s left side.
Secure long hair above shoulder level to prevent entangle-
ment in moving parts.
Keep all bystanders, children, and pets at least
50 ft. away. Bystanders should be encouraged to wear
eye protection. If you are approached, stop the engine and
cutting attachment. In the case of bladed units, there is the
added risk of injury to bystanders from being struck with
the moving blade in the event of a blade thrust or other
unexpected reaction of the saw.
Do not operate this unit when you are tired, ill, or under the
influence of alcohol, drugs, or medication.
Do not operate in poor lighting.
Do not operate in rain or use in damp or wet environ-
ments.
Keep firm footing and balance. Do not overreach. Over-
reaching can result in loss of balance or exposure to hot
surfaces.
Keep all parts of your body away from any moving part.
To avoid hot surfaces, never operate the unit with the bottom
of the engine above waist level.
Do not touch area around the muffler or cylinder of the unit.
These parts get hot from operation. Failure to heed this
warning could result in possible serious personal injury.
Carry the chain saw with the engine stopped, the guide bar
and saw chain to the rear, scabbard on the guide bar and
saw chain, and the muffler away from your body.
Always stop the engine and remove the spark plug wire be-
fore making any adjustments or repairs except for carburetor
adjustments.
Inspect the unit before each use for loose fasteners, fuel
leaks, etc. Replace any damaged parts before use.
The chain may rotate during carburetor adjustments.
It has been reported that vibrations from hand-held tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling, numbness and blanching of the fingers, usually apparent upon
exposure to cold. Hereditary factors, exposure to cold and
dampness, diet, smoking and work practices are all thought
to contribute to the development of these symptoms. It is
presently unknown what, if any, vibrations or extent of exposure may contribute to the condition. There are measures
that can be taken by the operator to possibly reduce the
effects of vibration:
a) Keep your body warm in cold weather. When operat
ing the unit wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
b) After each period of operation, exercise to increase blood
circulation.
c) Take frequent work breaks. Limit the amount of exposure
per day.
d) Keep the tool well maintained, fasteners tightened and
worn parts replaced.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician about
these symptoms.
Mix and store fuel in a container approved for gasoline.
Mix fuel outdoors where there are no sparks or flames. Wipe
up any fuel spillage. Move 30 ft. away from refueling site
before starting engine.
Stop the engine and allow to cool before refueling or storing
the unit.
Allow the engine to cool, empty the fuel tank, and secure
the unit from moving before transporting in a vehicle.
Check for damaged parts. Before further use of the tool, any
part that is damaged should be carefully checked to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of
moving parts, breakage of parts, mounting, and any other
conditions that may affect its operation. A guard or other part
that is damaged should be properly repaired or replaced by
an authorized service dealer. Be sure the chain stops moving
when the throttle trigger is released. Following this rule will
reduce the risk of shock, fire, or serious injury.

SPECIFIC SAFETY RULES
Kickback is a dangerous reaction that can lead to serious
injury. Kickback may occur when the moving chain contacts an object at the upper portion of the tip of the guide
bar or when the wood closes in and pinches the chain
in the cut. Contact at the upper portion of the tip of the
guide bar can cause the chain to dig into the object and
stop the chain for an instant. The result is a lightning-fast,
reverse reaction which kicks the guide bar up and back
toward the operator. If the chain is pinched along the top
of the guide bar, the guide bar can be driven rapidly back
toward the operator, which can cause loss of control and
may result in serious injury. Do not rely exclusively upon
the safety devices built into the product.
With a basic understanding of kickback, you can reduce
or eliminate the element of surprise. Sudden surprise
contributes to accidents.
Make sure that the area in which you are cutting is free
from obstructions. Do not let the nose of the guide bar
contact a log, branch, fence, or any other obstruction
while you are operating the unit. Have a planned retreat
path.
Cut only when visibility and light are adequate for you to
see clearly.
Do not use on a ladder or unstable support. Always cut
with both feet on solid ground to prevent being pulled off
balance.
To protect yourself from electrocution, do not operate
within 50 feet of overhead electrical lines.
Before starting the engine, make sure the chain is not
contacting any object.
Always cut with the engine running at full speed. Fully
squeeze the throttle trigger and maintain a steady cutting
speed.
Do not force tool. Use the correct tool for your applica-
tion. The correct tool will do the job better and safer at
the rate for which it is designed.
To protect yourself from falling branches, do not stand di-
rectly under the branch or limb being cut. This unit should
not be held at an angle over 60° from ground level.
Keep the handles dry, clean, and free of lubricant or fuel
mixture.
Shut off the engine and make sure the cutting attachment
has stopped before setting the unit down.
To prevent electrical shock or serious personal injury, do
not use this product with any AC power head.
Follow the sharpening and maintenance instructions for
the saw chain.
Use only the replacement guide bars and low kickback
chains specified for the unit.
Operate saw in well ventilated areas.
Do not operate the saw with one hand! Serious injury to
the operator, helpers, bystanders, or any combination of
these persons may results from one hand operation. This
saw is intended for two-handed use.
Use extreme caution when cutting small sized brush
and saplings because slender material may catch the
saw chain and be whipped toward you or pull you off
balance.
When cutting a limb that is under tension, be alert for
spring back so that you will not be struck when tension
in wood fibers are released.
Keep a good firm grip on the saw with both hands, the
right hand on the rear and the left hand on the front
handle, when the engine is running. Use a firm grip with
thumbs and fingers encircling the chain saw handles. A
firm grip will help you avoid kickback and maintain control
of the saw. Don’t let go.
Do not operate a chain saw in a tree unless you have
been specifically trained to do so.
REFUELING
FUEL IS HIGHLY FLAMMABLE. Take precautions when
using to reduce the chance of serious personal injury.
Store fuel in a cool, well-ventilated area, safely away from
spark and/or flame-producing equipment.
Store fuel in containers specifically designed for this
purpose.
Only refuel outdoors and do not smoke while refueling.
Add fuel before starting the engine. Never remove the cap
of the fuel tank or add fuel while the engine is running or
when the engine is hot.
If fuel is spilled, do not attempt to start the engine but
move the machine away from the area of spillage and
avoid creating any source of ignition until fuel vapors
have dissipated.
Replace all fuel tank and container caps securely.
If the fuel tank has to be drained, do this outdoors.
