the chain saw handles, with both hands on the saw and
position your body and arm to allow you to resist kickback
forces.
Kickback forces can be controlled by the operator, if
proper precautions are taken. Do not let go of the chain saw.
• Do not overreach and do not cut above shoulder height.
This
helps prevent unintended tip contact and enables better control of the
chain saw in unexpected situations.
• Only use replacement bars and chains specified by the
manufacturer.
Incorrect replacement bars and chains may cause
chain breakage and/or kickback.
• Follow the manufacturer’s sharpening and maintenance
instructions for the saw chain.
Decreasing the depth gauge
height can lead to increased kickback.
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 tool unplugged, 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.
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
B175.1-2012.
•
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
