SPECIFIC SAFETY RULES
SPECIFIC SAFETY RULES FOR TRIMMER USE
nReplace string head if cracked, chipped, or damaged in any way. Be sure the string head or blade is properly installedandsecurelyfastened.Failuretodosocancause serious injury.
nMake sure all guards, straps, deflectors, and handles are properly and securely attached.
nUse 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.
nNever operate unit without the grass deflector in place and in good condition.
nMaintain 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 BRUSHCUTTER AND BLADE USE
nAfter engine stops, keep rotating blade in thicker weeds or pulpy stalks until it stops.
nDo not operate the brushcutter unless the brushcutter guard is firmly secured in place and in good condition.
nUse heavy gloves when operating the brushcutter and when installing or removing blades.
nAlways 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.
nDo not attempt to touch or stop the blade when it is rotating.
nA 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.
nReplace 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.
nUse 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.
nThe 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.
nExercise 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.
nNever cut any material over 13 mm (1/2 in.) diameter.
nAlways wear the shoulder harness when using the brushcutter 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.
nNever use the brushcutter with the blade located 76 cm (30 in.) or more above the ground level.
