SPECIFIC SAFETY RULES

This product is intended for infrequent use by homeown-
ers and other occasional users for such general applica-
tions as trimming light and heavy vegetation, etc. It is not
intended for prolonged use. Prolonged periods of opera-
tion 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.
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.

Never use blades, flailing devices, wire, or rope on trimmer
attachment.
 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 BRUSH
CUTTER AND BLADE USE

Brush cutter blades coast after throttle trigger is released
or engine is stopped. Keep the rotating blade in thicker
weeds or pulpy stalks until the blade completely 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 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 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.

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 brush cutter with the blade located 30 in.
or more above the ground level.

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
idles. When the unit is turned off make sure the cutting
attachment has stopped before the unit is set down.
