General Safety Rules

 

Allow the engine to cool; empty the fuel tank into a con-

tainer approved for fuel 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 attach-

ment has stopped before the unit is set down.

  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 

operation can cause circulatory problems in the user’s 

hands due to vibration. For such use, it may be appropri

-

ate 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 in

-

stalled 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

  Brushcutter 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 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 rotat

-

ing.

  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 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 blade is suited for cutting thicker weeds or pulpy 

stalks only. Do not use for any other purpose. Never use 

the 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 con

-

tact may cause the blade to stop for an instant, and sud

-

denly “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 ma

-

terial 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.

  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.
