Service

Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury. Refer to the Maintenance section of this manual.
When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electric shock or injury.

Guard Against Kickback

WARNING: KICKBACK may occur when 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.Tip contact in some cases may cause a lightning-fast reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could result in serious injury to the user.The following precautions should be followed to minimize kickback:

Grip pole saw firmly. Hold the saw firmly with both hands when the unit is running. Use a firm grip with thumbs and fingers encircling the saw handle and pole.
Do not overreach.
Keep proper footing and balance at all times.
Don’t let the noise of the guide bar contact a log, branch, ground, or other obstruction.
Do not extend the pole saw handle above shoulder height.
Use devices such as reduced kickback chain, chain braking system, and special guide bars that reduce the risks associated with kickback.
Only use replacement bars and chains specified by the manufacturer or the equivalent.
Never let the moving chain contact any object at the tip of the guide bar.
Keep the working area free from obstructions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid any obstruction that your saw chain could hitwhile you are cutting through a particular log or branch.
Keep your saw chain sharp and properly tensioned. A loose or dull chain can increase the chance of kickback. Check tension at regular intervals with the motor stopped and battery removed.
Begin and continue cutting only with the chain moving at full speed. If the chain is moving at a slower speed, there is a greater chance for a kickback to occur.
Cut one branch at a time.
Use extreme caution when re-entering a previous cut.Engage spiked bumpers into the wood and allow the chain to reach full speed before proceeding with the cut.
Do not attempt plunge cuts or bore cuts.
Watch for shifting branches or other forces that could close a cut and pinch or fall into the chain.

Kickback Safety Features

WARNING: The following features are included on your pole saw to help reduce the hazard of kickback; however such features will not totally eliminate this dangerous reaction. As a pole saw users do not rely only on safety devices. You must follow all safety precautions, instructions, and maintenance in this manual to help avoid kickback and other forces which can result in serious injury.

Reduced-Kickback Guide Bar, designed with a small radius tip which reduces the size of the kickback danger zone on bar tip. A reduced- kickback guide bar is one that has been demonstrated to significantly reduce the number and seriousness of kickbacks when tested in accordance with safety requirements for electric chain saws.
Reduced Kickback Chain, designed with a contoured depth gauge and guard link which deflect kickback force and allow the wood to gradually ride into the cutter. A reduced-kickback chain is a chain that has met the kickback performance requirements of ANSI B175.1–2012. when tested on the representative sample of chain saws.
