KICKBACK DANGER Kickback can lead to dangerous loss of control of the Power PrunerTM and result in serious injury to the operator or any one standing close by. Hold the Power PrunerTM firmly with both hands with thumbs and fingers encircling the front and rear handles. Be aware of the down and outward path the pruner will take after the cut is made. Kickback may occur when the moving saw chain at the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. In some cases this may cause a lightning-fast reverse action, kicking the guide bar and saw chain up and back or down and back towards the operator. Either of these reactions may cause the operator to lose control of the Power PrunerTM which could result in serious personal injury. With a basic understanding of kickback, you can reduce or eliminate the element of surprise which contributes to accidents. Avoid contact of the guide bar tip with any object while the saw chain is moving. POWER PRUNERTM ATTACHMENT OPERATOR'S MANUAL 7 Cut only wood. Avoid striking concrete, metal, wire, or other obstructions which could cause kickback or damage to the saw chain. If the saw chain does strike a foreign object, immediately stop the engine, inspect and repair the Power PrunerTM if necessary. EQUIPMENT Before operation a complete check of the unit must be performed; • Check unit for loose/missing nuts, bolts and screws. Tighten and/or replace as needed.
