is designed for light to medium trimming of limbs and branches up to 203mm (8 in.) in
diameter. Follow these tips for successful operation.
• Plan cut carefully. Check direction branch will fall.
• Plan retreat path from falling branch. Cut branches bounce
when striking ground.

Hold "cutting shoe" against branch. This will prevent whipping
of the branch. DO NOT use back and forth sawing action.

bar may occur..

control
