OPERATION

WARNING:

To avoid burns from hot surfaces, never operate unit with the bottom of the engine above waist level.

Hold the brushcutter with your right hand on the rear handle and the your left hand on the “J” handle. Keep a firm grip with both hands while in operation. Brushcutter should be held at a comfortable position with the rear handle about hip height. Maintain your grip and balance on both feet. Position yourself so that you will not be drawn off balance by the kickback reaction of the cutting blade.

Adjust the shoulder harness to position the brushcutter at a comfortable operating position and to assure that the shoulder harness will reduce the risk of operator contact with the blade.

WARNING:

Always hold the brushcutter away from the body keeping clearance between the body and the product. Any contact with the housing can result in burns and/or other serious personal injury.

BLADE THRUST

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 re- action 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 oc- cur in areas where it is difficult to see the material being cut. For cutting ease and safety, approach the weeds being cut with the brushcutter from the right to the left. In the event an unexpected object or woody stock is encountered, this practice could minimize the blade thrust reaction.

TRI-ARC®BLADE

The Tri-Arc®blade is suited only for thicker weeds and pulpy stalks. When the blade becomes dull, it can be turned over to extend the life of the blade. Do not sharpen the Tri-Arc®blade.

CUTTING TECHNIQUE - BLADE

See Figure 14.

WARNING:

Extreme care must be taken when using blades to ensure safe operation. Read the safety information for safe op- eration using the blade, refer to Specific Safety Rules for Brushcutter and Blade Use earlier in this manual.

Always hold brushcutter on your right side with both hands when operating. Use a firm grip on both handles.

Maintain your grip and balance on both feet. Position yourself so that you will not be drawn off balance by the kickback reaction of the cutting blade.

Inspect and clear the area of any hidden objects such as glass, rocks, concrete, fencing, wire, wood, metal, etc.

Never use blades near sidewalks, fencing, posts, build- ings or other immovable objects.

Never use a blade after hitting a hard object without first in- specting it for damage. Do not use if any damage is detected.

The unit is used as a scythe, cutting from the right to the left in a broad sweeping action from side to side.

Use only the Tri-Arc®blade. To install any other brand blade or cutting head to this brushcutter can result in serious personal injury.

OPERATING THE TRIMMER

See Figures 15.

Hold the trimmer with your right hand on the rear handle and your left hand on the “J” handle. Keep a firm grip with both hands while in operation. Trimmer should be held at a comfortable position with the rear handle about hip height.

Always operate trimmer at full throttle. Cut tall grass from the top down. This will prevent grass from wrapping around the shaft housing and string head which could cause dam- age from overheating. If grass becomes wrapped around the string head, STOP THE ENGINE, disconnect the spark plug wire, and remove the grass. Prolonged cutting at partial throttle will result in lubricant dripping from the muffler.

TO ADVANCE THE CUTTING LINE (REEL EASY STRING HEAD)

Line advance is controlled by tapping the string head on grass while running engine at full throttle.

Run engine at full throttle.

Tap the knob on ground to advance line. The line advances each time the knob is tapped. Do not hold the knob on the ground.
