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 start or run the engine in a closed or poorly venti-
lated area; breathing exhaust fumes can kill.
Clear the work area before each use. Remove all objects
such as rocks, broken glass, nails, wire, or loose string
which can be thrown or become entangled in the cutting
line or blade.
Always wear eye protection with side shields marked to
comply with ANSI Z87.1 along with hearing protection
when operating this equipment.
Wear heavy, long pants, long sleeves, boots, and gloves.
Do not wear loose tting clothing, short pants, sandals,
or go barefoot. Do not wear jewelry of any kind.
Heavy protective clothing may increase operator fa-
tigue, 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 tem-
peratures are cooler.
Product users on United States Forest Service land,
and in some states, must comply with re prevention
regulations. This product is equipped with a spark arres-
tor; however, other user requirements may apply. Check
with your federal, state, or local authorities.
Never operate this unit on the operator’s left side.
Secure long hair above shoulder level to prevent en-
tanglement 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 be-
ing 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 inuence of alcohol, drugs, or medication.
Do not operate in poor lighting.
Keep rm 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 mufer or cylinder of the
unit, these parts get hot from operation. Contact with
hot surfaces could result in possible serious personal
injury.
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 cutting attachment should never rotate at idle dur-
ing normal use. The cutting attachment may rotate at
idle 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 in-
clude tingling, numbness, and blanching of the ngers,
usually apparent upon exposure to cold. Hereditary
factors, exposure to cold and dampness, diet, smok-
ing, 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
operating the unit wear gloves to keep 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 condi-
tion, immediately discontinue use and see your physi-
cian about these symptoms.
Mix and store fuel in a container approved for gasoline.
Mix fuel outdoors where there are no sparks or ames.
Wipe up any fuel spillage. Move 30 ft. away from refu-
eling site before starting engine. Slowly remove the fuel
cap after stopping engine. Do not smoke when refuel-
ing.
Stop the engine and allow to cool before refueling or
storing the unit.
Allow the engine to cool; empty the fuel tank into a
container approved for fuel and secure the unit from
moving before transporting in a vehicle.
Wear your 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 cutting
attachment has stopped before the unit is set down.

Cutting Tips
See Figures 12 and 13.
1. Avoid hot surfaces by always keeping the tool away
from your body. (Proper operating position is shown in
Figures 9 and 10.)
2. Keep the trimmer tilted toward the area being cut; this
is the best cutting area.
3. The curved shaft trimmer cuts when passing the unit
from right to left. the straight shaft trimmer cuts when
passing the unit from left to right. This will avoid
throwing debris at the operator. Avoid cutting in the
dangerous area shown in gures 12 and 13.
4. Use the tip of string to do the cutting; do not force
string head into uncut grass.
5. Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs and wood may
wear string rapidly.
6. Avoid trees and shrubs. Tree bark, wood moldings, sid-
ing and fence posts can easily be damaged by the string.
