Have your ECHO dealer repair stop switch before using pruner again. A PRUNING TECHNIQUES The Power PrunerTM is designed for light to medium trimming of limbs and branches up to 203 mm (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. • Long branches should be removed in several pieces. • Do not stand directly beneath branch being cut. • When ready to cut: Hold "cutting shoe" against branch. This will prevent whipping of the branch. DO NOT use back and forth sawing action. • Look out for branch immediately behind the branch being cut. If saw chain hits rear branch damage to saw chain may occur. • Accelerate to full throttle. • Apply cutting pressure. • Ease cutting pressure when nearing end of cut to maintain control. • When pruning a limb 102 mm (4 in.) diameter or larger cut as follows: 1. Under cut 1/4 limb diameter near tree trunk. 2. Finish top cut slightly farther out on limb. 3. Flush cut stub at trunk. • DO NOT use for felling or bucking.
