•Always use the blade suited for the job.
•Do not hit rocks, stones, tree stumps, and other foreign objects with the blade.
•Do not cut into the ground with the blade.
•If blade strikes an obstruction, stop engine immedi- ately and inspect blade for damage.
•Do not operate with a dull, bent, fractured or discoloured blade and worn or damaged nut.
•Do not run engine at full throttle without a load.
•Remove all foreign objects from work area.
•Do not operate brushcutter without shoulder harness and shield.
SCYTHING WEEDS. This is cutting by swinging the cutting attachment in a level arc. It can quickly clear areas of field grass and weeds. Scything should not be used to cut large, tough weeds or woody growths.
If a sapling or shrub binds the cutting attachment, do not use the cutting attachment as a lever to free the bind, because this will cause cutting attachment failure.
Instead, shut off the engine and push the sapling or shrub to free the blades.
Do not use a cracked or damaged blade.
WARNING 
DANGER
ALWAYS STOP THE ENGINE WHEN A CUTTING ATTACHMENT JAM OCCURS. DO NOT ATTEMPT TO REMOVE AN OBJECT CAUSING A JAM IF THE ENGINE IS RUNNING. SEVERE INJURY CAN OCCUR IF A JAM IS REMOVED AND THE CUTTING ATTACHMENT SUDDENLY STARTS.

WARNING 
DANGER
BE SURE YOU UNDERSTAND THE REACTION FORCES OF PUSH AND PULL, AND KICKBACK DESCRIBED IN THIS MANUAL, AND HOW THESE FORCES MAY AFFECT YOUR BALANCE IN THE OPERATION OF A UNIT.
PUSH. The operator may feel the unit push toward him when he tries to cut the object on right. If he cannot hold the blade in the cut, a kickback may occur when the blade is pushed out to where the teeth at the outside furthest point from the operator are cutting. The blade will “kickback” sideways.
PULL. The opposite of push. When object on left, the operator may feel the unit pull away. Although this pull type of cutting may cause sawdust to be thrown back at the operator, it is recommended for sawing off heavy brush because the cutting is smoother and more stable than when the unit pushes.
KICKBACK. This may occur when the moving blade at the front of the blade circle contacts strong brush or trees. The force that occurs pushes the entire unit and blade violently away in an arc. Kickback is a danger to a bystander and also a jolting force to the operator.
