SPECIFIC SAFETY RULES

  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.

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 recommended or equivalent replacement line in 

the cutting head. Do not use any other cutting attachment. 

To install any other type 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  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.
