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 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.
Wear safety glasses or goggles that are marked to comply
with ANSI Z87.1 standard when operating this product.
Wear heavy, long pants, 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.
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.
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, 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.
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.
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 during
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 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 oper-
ating 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,
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. 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.

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
SPECIFIC SAFETY RULES
SPECIFIC SAFETY RULES FOR TRIMMER
USE
Inspect before use. Replace damaged parts. Make sure
fasteners are in place and secure. Check for fuel leaks.
Replace string head if cracked, chipped, or damaged
in any way. Be sure the string head or blade is properly
installed and securely fastened. Failure to do so can cause
serious injury.
Make sure all guards, straps, deflectors, and handles are
properly and securely attached.
Use only the manufacturer’s replacement line in the
cutting head. Do not use any other cutting attachment.
To install any other brand of replacement line or cutting
head to this string trimmer can result in serious personal
injury. Never use, for example, wire or wire-rope, which
can break off and become a dangerous projectile.
Never operate unit without the grass deflector in place
and in good condition.
Maintain a firm grip on both handles while trimming. Keep
string head below waist level. Never cut with the string
head located over 30 in. or more above the ground.
SPECIFIC SAFETY RULES FOR
BRUSHCUTTER AND BLADE USE
After engine stops, keep rotating blade in thicker weeds
or pulpy stalks until it stops.
Do not operate the brushcutter unless the brushcutter
guard is firmly secured in place and in good condition.
Use heavy gloves when operating the brushcutter and
when installing or removing blades.
Always stop the engine and remove the spark plug wire
before attempting to remove any obstruction caught or
jammed in the blade or before removing and installing
the blade.
Do not attempt to touch or stop the blade when it is
rotating.
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.
A coasting blade can cause injury while it continues
to spin after the engine is stopped or throttle trigger
released. Maintain proper control until the blade has
completely stopped rotating.
Replace any blade that has been damaged. Always make
sure blade is installed correctly and securely fastened
before each use. Failure to do so can cause serious
injury.
Use only the manufacturer’s replacement Tri-Arc
intended for use on this brushcutter. Do not use any other
blade. To install any other brand blade or cutting head to
this brushcutter can result in serious personal injury.
The Tri-Arc® blade is suited for cutting thicker weeds or
pulpy stalks only. Do not use for any other purpose. Never
use the Tri-Arc® blade to cut woody brush.
Exercise extreme caution when using the blade with this
unit. Blade thrust is the reaction that may occur when
the spinning blade contacts anything it cannot cut. This
contact may cause the blade to stop for an instant, and
suddenly “thrust” the unit away from the object that was
hit. This reaction can be violent enough to cause the operator to lose control of the unit. Blade thrust can occur
without warning if the blade snags, stalls, or binds. This is
more likely to occur in areas where it is difficult to see the
material being cut. For cutting ease and safety, approach
the weeds being cut from the right to the left. In the event
an unexpected object or woody stock is encountered, this
could minimize the blade thrust reaction.
Never cut any material over 1/2 in. diameter.
Always wear the shoulder harness when using the brush-
cutter and adjust to a comfortable operating position.
Maintain a firm grip on both handles while cutting with a
blade. Keep the blade away from your body and below
waist level.
Never use the brushcutter with the blade located 30 in.
or more above the ground level.

FUELING AND REFUELING THE TRIMMER
FUEL MIXTURE
This product is powered by a 2-cycle engine and requires
pre-mixing gasoline and 2-cycle lubricant. Pre-mix unleaded
gasoline and 2-cycle engine lubricant in a clean 1 gallon
container approved for gasoline.
Recommended fuel: This engine is certified to operate on
unleaded gasoline intended for automotive use.
Mix a high quality 2-cycle engine lubricant at 2.6 oz. per
gallon (US).
Do not use automotive lubricant or 2-cycle outboard
lubricant.
DO NOT mix quantities larger than usable in a 30 day
period.
HIGH QUALITY 2-CYCLE ENGINE LUBRICANT
GASOLINE LUBRICANT
1 gallon (US) 2.6 oz.
1 liter 20 cc (20 ml)
NOTE: It is normal for smoke to be emitted from a new
engine after first use.
WARNING:
Always shut off engine before fueling. Never add fuel to
a machine with a running or hot engine. Move at least
30 ft. from refueling site before starting engine. Do not
smoke! Failure to heed this warning could result in serious personal injury.
OXYGENATED FUELS
Some conventional gasolines are blended with alcohol or an
ether compound. These gasolines are collectively referred
to as oxygenated fuels. To meet clean air standards, some
areas of the United States and Canada use oxygenated fuels
to help reduce emissions.
If using an oxygenated fuel, make sure it is unleaded and
meets the minimum octane rating requirements. Before using
an oxygenated fuel, try to confirm the fuel’s contents. Some
states/provinces require this information to be posted on the
pump. The following are the EPA approved percentages of
oxygenates:
Ethanol (ethyl or grain alcohol) 10% by volume. You
may use gasoline containing up to 10% ethanol by volume.
Gasoline containing ethanol may be marketed under the
name “Gasohol.” Do not use E85 fuel.
MTBE (methyl tertiary butyl ether) 15% by volume. You
may use gasoline containing up to 15% MTBE by volume.
Methanol (methyl or wood alcohol) 5% by volume. You
may use gasoline containing up to 5% methanol by volume
as long as it also contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more
than 5% methanol by volume may cause starting and/or
performance problems. It may also damage metal, rubber,
and plastic parts of the product or your fuel system.
If you notice any undesirable operating symptoms, try another service station or switch to another brand of gasoline.
NOTE: Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more
than the percentages of oxygenates stated previously are
not covered under warranty.
FILLING TANK
C l ean su r face a r o und fu e l cap to pre vent
contamination.
Loosen fuel cap slowly. Rest the cap on a clean
surface.
Carefully pour fuel into the tank. Avoid spillage.
Prior to replacing the fuel cap, clean and inspect the
gasket.
Immediately replace fuel cap and hand tighten. Wipe up
any fuel spillage.

OPERATING THE TRIMMER
See Figure 15.
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.
OPERATION
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.
Always operate trimmer at full throttle. 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. Prolonged cutting at partial
throttle will result in lubricant dripping from the muffler.
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 head can
result in burns and/or other serious personal injury.
TO ADVANCE THE CUTTING LINE (BUMP FEED
STRING HEAD)
Line advance is controlled by tapping the string head on
grass while running engine at full throttle.
Run engine at full throttle.
Tap the 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 knob in while pulling on line(s) to manually ad-
vance the line.
CUTTING TIPS
See Figures 16 -17.
Avoid hot surfaces by always keeping the tool away from
your body. (Proper operating position shown in figure 15.)
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.
11 — English
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.
GRASS DEFLECTOR LINE TRIMMING CUT-OFF
BLADE
See Figure 18.
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.
OPERATING THE BRUSHCUTTER
See Figures 19 - 20.
Hold the brushcutter with your right hand on the rear handle
and the your hand on the “J” handle. Keep a firm grip with
both hands while in operation. Brushcutter should be held at
a comfortable position with the rear handle about hip height.
Maintain your grip and balance on both feet. Position yourself
so that you will not be drawn off balance by the kickback
reaction of the cutting blade.
Adjust the shoulder harness to position the brushcutter
at a comfortable operating position and to assure that the
shoulder harness will reduce the risk of operator contact
with the blade.
BLADE THRUST
Exercise extreme caution when using the blade with this
unit. Blade thrust is the reaction that may occur when the
spinning blade contacts anything it cannot cut. This contact
may cause the blade to stop for an instant, and suddenly
“thrust” the unit away from the object that was hit. This reaction can be violent enough to cause the operator to lose
control of the unit. Blade thrust can occur without warning
if the blade snags, stalls, or binds. This is more likely to occur in areas where it is difficult to see the material being cut.
For cutting ease and safety, approach the weeds being cut
with the brushcutter from the right to the left. In the event
an unexpected object or woody stock is encountered, this
practice could minimize the blade thrust reaction.
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
OPERATION
TRI-ARC® BLADE
The Tri-Arc® blade is suited only for thicker weeds and pulpy
stalks. When the blade becomes dull, it can be turned over
to extend the life of the blade. Do not sharpen the Tri-Arc®
blade.
CUTTING TECHNIQUE - BLADE
WARNING:
Extreme care must be taken when using blades to ensure safe operation. Read the safety information for safe
operation using the blade, refer to Specific Safety Rules
for Brushcutter and Blade Use earlier in this manual.
Always hold brushcutter on your right side with both hands
when operating. Use a firm grip on both handles.
Maintain your grip and balance on both feet. Position
yourself so that you will not be drawn off balance by the
kickback reaction of the cutting blade.
Inspect and clear the area of any hidden objects such as
glass, rocks, concrete, fencing, wire, wood, metal, etc.
Never use blades near sidewalks, fencing, posts, build-
ings or other immovable objects.
Never use a blade after hitting a hard object without first
inspecting it for damage. Do not use if any damage is
detected.
The unit is used as a scythe, cutting from the right to the
left in a broad sweeping action from side to side.
Use only the Tri-Arc® blade. To install any other brand
blade or cutting head to this brushcutter can result in
serious personal injury.
