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  BRUSH- 

CUTTER 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 op-
erator 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 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 76 cm 

(30 in.) or more above the ground level.
