■■
comply with ANSI Z87.1 standard when operating this
product.
■■
■ 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.
■■
■ 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 15 m
■■
(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.
■■
■■
■ 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 string head or blade will rotate during carburetor

■■
■ 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 9 m (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.

SPECIFIC SAFETY RULES
SPECIFIC SAFETY RULES FOR TRIMMER
USE
■■
■ 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 string in the
■■
cutting head. Do not use any other cutting attachment.
To install any other brand of cutting head to this string
trimmer can result in serious personal injury.
■■
■ 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 76 cm (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.
■■
■ 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®
■■
blade 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 13 mm (1/2 in.) diameter.
■■
■■
■ Always wear the shoulder harness when using the
■■
brushcutter and adjust to a comfortable operating
position. Maintain a firm grip on both handles while
cutting with a blade. Keep the blade away from body and
below waist level.
■■
■ Never use the brushcutter with the blade located 76 cm
■■
(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 oil. Pre-mix unleaded
gasoline and 2-cycle engine oil 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 oil at 2.6 oz. per
gallon (US).
Do not use automotive oil or 2-cycle outboard oil.
DO NOT mix quantities larger than usable in a 30 day period.
FUEL MIXTURE
HIGH QUALITY 2-CYCLE ENGINE OIL
GASOLINE OIL
1 gallon (US) 2.6 oz.
1 Liter 20 cc (20 ml)
WARNING:
To avoid burns from hot surfaces, never operate unit with
the bottom of the engine above waist level.
Hold the trimmer with the right hand on the rear handle and
the 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 may 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 oil dripping from the muffler.
FILLING TANK
1. Clean surface around fuel cap to prevent contamination.
2. Loosen fuel cap slowly. Rest the cap on a clean surface.
3. Carefully pour fuel into the tank. Avoid spillage.
4. Prior to replacing the fuel cap, clean and inspect the
gasket.
5. Immediately replace fuel cap and hand tighten. Wipe up
any fuel spillage.
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. (9 m) from refueling site before starting engine. Do not
smoke!

OPERATION
TO ADVANCE THE CUTTING LINE
String advance is controlled by tapping the string head on
grass while running engine at full throttle.
1. Run engine at full throttle.
2. Tap the spool retainer on ground to advance string. The
string advances each time the spool retainer is tapped.
Do not hold the spool retainer 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 string is worn too short you may not be able to
advance the string by tapping it on the ground. If so, stop
the engine, and manually advance the string.
TO ADVANCE THE CUTTING LINE MANUALLY
Push the spool retainer down while pulling on string(s) to
manually advance the string.
CUTTING TIPS
See Figures 16 and 17.
■ 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
■ Use the tip of string to do the cutting; do not force string
head into uncut grass.
■ Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wear string rapidly.
■ Avoid trees and shrubs. Tree bark, wood moldings,
siding, and fence posts can easily be damaged by the
string.
GRASS DEFLECTOR LINE TRIMMING CUT-OFF BLADE
Figures 16 and 17
.
See Figure 18.
The trimmer is equipped with a line trimming cut-off blade
on the grass deflector. For best cutting, advance string until
it is trimmed to length by the cut-off blade. Advance the
string whenever you hear the engine running faster than
normal, or when trimming efficiency diminishes. This will
maintain best performance and keep the string long enough
to advance properly.
