• 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 user.
The following precautions should be followed to minimize
kickback:
(1.) Grip Saw Firmly. Hold the chain saw firmly with both hands
when the motor is running. Use a firm grip with thumbs and fingers
encircling the chain saw handles. Chain saw will pull forward when
cutting on the bottom edge of the bar, and push backward when
cutting along the top edge of the bar.
(2.) Do not over reach.
(3.) Keep proper footing and balance at all times.
(4.) Don't let the nose of the guide bar contact a log, branch, ground
or other obstruction.
(5.) Don't cut above shoulder height.
(6.) Use devices such as low kickback chain and reduced kickback
guide bars that reduce the risks associated with kickback.
(7.) Only use replacement bars and chains specified by the
manufacturer or the equivalent.
(8.) Never let the moving chain contact any object at the tip of the
guide bar.
(9.) 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.
(10.) 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, never
with the motor running.
(11.) 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.

(12.) Cut one log at a time.
(13.) Use extreme caution when re-entering a previous cut. Engage
ribbed bumpers into wood and allow chain to reach full speed
before proceeding with cut.
(14.) Do not attempt plunge cuts or bore cuts.
(15.) Watch for shifting logs or other forces that could close a cut
and pinch or fall into chain.
• Power Supply
Connect chain saw battery charger to correct voltage, that is, be
sure that the voltage supplied is the same as that specified on the
nameplate of the tool.
Kickback Safety Features
WARNING: The following features are included on your saw
to help reduce the hazard of kickback; however such features
will not totally eliminate this dangerous reaction. As a chain 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 B175.1-1991.
• Do not operate chain saw while in a tree, on a ladder, on a
scaffold, or from any unstable surface.
• Hold tool by insulated gripping surfaces when performing an
operation where the cutting tool may contact hidden wiring.
Contact with a "live" wire will make exposed metal parts of the tool
"live" and shock the operator.
• Do not attempt operations beyond your capacity or
experience. Read thoroughly and understand completely all
instructions in this manual.
