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.
Do not start or operate the engine in a confined space,
building, near open windows, or in other unventilated
space where dangerous carbon monoxide fumes can
collect. Carbon monoxide, a colorless, odorless, and
extremely dangerous gas, can cause unconsciousness
or death.
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. Failure to do so could
result in objects being thrown into your eyes and other
possible serious injuries.
Wear heavy, long pants, long sleeves, boots, and gloves.
Do not wear loose fitting clothing, short pants, sandals,
or go barefoot. Do not wear jewelry of any kind.
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
entanglement 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, upset, or
under the influence of alcohol, drugs, or medication.
Do not operate in poor lighting.
Keep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance or exposure
to hot surfaces.
 Do not use on a ladder, rooftop, tree, or other unstable
support. Stable footing on a solid surface enables better
control of the unit in unexpected situations.
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. 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.
Never use blades, flailing devices, wire, or rope on trim-
mer attachment. Never use flailing devices, wire, or rope
on any attachment.
The cutting attachment should never rotate at idle during
normal use. The cutting attachment may rotate at idle
during carburetor adjustments.
It has been reported that vibrations from hand-held tools
maycontribute 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 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 condition,
immediatelydiscontinue use andsee yourphysician about
these symptoms.
Store fuel in a container approved for gasoline.
Wipe up any fuel spillage. Move 30 ft. away from refueling
site before starting engine. Slowly remove the fuel cap
after stopping engine. Do not smoke when refueling.
Stop the engine and allow to cool before refueling or
storing the unit.

head located over 30 in. or more above the ground.
This product is intended for infrequent use by homeowners
and other occasional users for such general applications
as trimming light and heavy vegetation, etc. It is not
intended for prolonged use. Prolonged periods of
operation can cause circulatory problems in the
user’s hands due to vibration. For such use, it may be
appropriate to use a product having an anti-vibration
feature.
Save these instructions. Refer to them frequently and use
them to instruct others who may use this tool. If you loan
someone this tool, loan them these instructions also.
GENERAL SAFETY RULES
Allow the engine to cool; empty the fuel tank, 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

OPERATING THE TRIMMER
See Figure 9.
WARNING:
Engine housing can become hot during trimmer operation.
Do not rest or place your arm, hand, or any body part
against the engine housing during trimmer operation.
Only hold the trimmer as shown in figure 9 with all body
parts clear of engine housing. Extended contact with
the engine housing can result in burns or other injuries.
WARNING:
Always position the unit on the operator’s right side. The
use of the unit on the operator’s left side will expose the
user to hot surfaces and can result in possible burn injury.
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
Hold the trimmer with your right hand on the rear handle
and your left hand on the front handle. Keep a firm grip with
both hands while in operation. Trimmer should be held at a
comfortable position with the rear handle about hip height.
Cut tall grass from the top down. This will prevent grass from
wrapping around the shaft housing and string head which
could cause damage from overheating. If grass becomes
wrapped around the string head, STOP THE ENGINE,
disconnect the spark plug wire, and remove the grass.
WARNING:
Always hold the string trimmer away from the body
keeping clearance between the body and the product.
Any contact with the housing or string trimmer cutting

OPERATION
CUTTING TIPS
See Figures 9 - 11.
Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 9.)
Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
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 illustration.
Use the tip of line to do the cutting; do not force string
head into uncut grass.
Wire and picket fences cause extra line wear, even
breakage. Stone and brick walls, curbs, and wood may
wear line rapidly.
Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the line.
TO ADVANCE THE CUTTING LINE
Line advance is controlled by tapping the string head on
grass while running engine at full throttle.
Run engine at full throttle.
Tap the bump knob on ground to advance line. The line
advances each time the knob is tapped. Do not hold the
knob on the ground.
NOTE: The line trimming cut-off blade on the grass deflector
will cut the line to the correct length.
NOTE: If the line is worn too short you may not be able to
advance the line by tapping it on the ground. If so, stop the
engine and manually advance the line.
To advance the cutting line manually:
Stop the engine and disconnect the spark plug wire.
Push the bump knob down while pulling on line(s) to
manually advance the line.
GRASS DEFLECTOR LINE TRIMMING CUT-OFF
BLADE
See Figure 12.
The trimmer is equipped with a line trimming cut-off blade
on the grass deflector. For best cutting, advance line until it
is trimmed to length by the cut-off blade. Advance the line
whenever you hear the engine running faster than normal,
or when trimming efficiency diminishes. This will maintain
best performance and keep the line long enough to advance
properly.
