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 instruc-
tions before using this product.

 Follow all safety instruc-

tions. 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.

Always  wear  safety  glasses  with  side  shields.
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 regula-
tions.  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.

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.

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.

GENERAL SAFETY RULES

Always stop the engine and remove the spark plug wire 
before  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 ex-

posure 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. 
Following this rule will reduce the risk of shock, fire, or 
serious injury.
