The Power PrunerTM 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.
•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 and guide bar 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 fol- lows:
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.
