WARNING:
Read and understand all instructions. Failure to fol-
low all instructions listed below, may result in electric
shock, fire, and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Read these instructions and the instructions for the power
head thoroughly before using the attachment.
Know the tool. Read and understand the operator’s
manual and observe the warnings and instruction labels
affixed to the tool.
Do not allow children or untrained individuals to use this
unit.
Always wear eye protection with side shields marked to
comply with ANSI Z87.1 and hearing protection when
operating this unit.
Wear heavy long pants, a long-sleeved shirt, boots, and
gloves. Do not wear loose fitting clothing, short pants,
jewelry of any kind, or go barefoot.
Secure long hair so it is above shoulder level to prevent
entanglement in any moving parts.
Keep all bystanders, children, and pets at least 50 ft.
away. Bystanders should be encouraged to wear eye
protection.
Stay alert, watch what you are doing, and use common
sense when operating a power tool. Do not use tool
while tired or under the influence of drugs, alcohol, or
GENERAL SAFETY RULES
medication. A moment of inattention while operating
power tools may result in serious personal injury.
Do not operate in poor lighting.
Do not overreach. Keep proper footing and balance at all
times. Proper footing and balance enables better control
of the tool in unexpected situations.
Keep all parts of your body away from any moving part.
Do not touch areas around the muffler or cylinder of the
power head. These parts get hot from operation. Failure
to heed this warning 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 unit before each use for loose fasteners and
damaged or missing parts. Correct before using the
attachment. Failure to do so can cause serious injury.
Use only manufacturer’s recommended or equivalent
replacement parts. Failure to do so may cause poor
performance, possible injury, and will void your warranty.
Do not, under any circumstance, use any attachment or
accessory on this product, which was not provided with
the product, or identified as appropriate for use with this
product in the operator’s manual.
Avoid dangerous environments. Do not use the attachment
in damp or wet locations. Do not use in rain.
Use the right attachment. Do not use attachment for any
job except that for which it is intended.
SPECIFIC SAFETY RULES
Ensure handle is mounted in accordance with the assem-
bly instructions in this manual.
Do not attach blade without proper installation of all
required parts. Failure to use proper parts can cause the
blade to fly off and seriously injure the operator and/or
bystanders.
Always use a blade in good condition. A worn blade is
more likely to snag and thrust.
After engine stops, keep rotating blade in thicker weeds
or pulpy stalks until it stops.
Do not operate the brush cutter unless the brush cutter
guard is firmly secured in place and in good condition.
Use heavy gloves when operating the brush cutter 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 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 bent, warped, cracked,
chipped, or 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 brush cutter. Do not use any other
blade. To install any other brand blade or cutting head to
this brush cutter 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.

3 — English
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 approach could minimize the blade thrust reaction.
Never cut any material over 1/2 in. diameter.
SPECIFIC SAFETY RULES
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 body and below waist
level. Never use the brush cutter with the blade located
30 in. or more above the ground level.
To prevent electrical shock or serious personal injury, do
not use this product with any electric power head.
Save these instructions. Refer to them frequently and
use them to instruct others who may use this product.
If you loan someone this product, loan them these
instructions also to prevent misuse of the product and
possible injury.
