Pole Saw Names And Terms - Black & Decker LPP120B Instruction Manual

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 hit while 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 kickback to occur.
• Cut one branch at a time.
• Use extreme caution when re-entering a previous cut. Engage
spiked bumpers into wood and allow chain to reach full speed
before proceeding with 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 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 user
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 which has been demonstrated
to significantly reduce the number and seriousness of kickbacks
when tested in accordance with safety requirements for electric
chain saws.
• low-Kickback Chain, designed with a contoured depth gauge
and guard link which deflect kickback force and allow wood to
gradually ride into the cutter. A low-kickback chain is a chain which
has met kickback performance requirements of ANSI B175.1 when
tested on the representative sample of chain saws.
