Causes And Operator Prevention Of Kickback - Black and Decker LCS1020 Manual De Instrucciones

ofcontrol.
• Use extreme caution when cutting
brush and saplings. The slender material
may catch the saw chain and be whipped
toward you or pull you off balance.
• Carry the chain saw by the front
handle with the chain saw switched
off and away from your body. When
transporting or storing the chain
saw always fit the scabbard. Proper
handling of the chain saw will reduce the
likelihood of accidental contact with the
moving saw chain.
• Follow instructions for lubricating,
chain tensioning and changing
accessories. Improperly tensioned or
lubricated chain may either break or
increase the chance for kickback.
• Keep handles dry, clean, and free from
oil and grease. Greasy, oily handles are
slippery causing loss of control.
• Cut wood only. Do not use chain
saw for purposes not intended. For
example: do not use chain saw for
cutting plastic, masonry or non-wood
building materials. Use of the chain
saw for operations different than intended
could result in a hazardous situation.
CAUSES AND OPERATOR
PREVENTION OF KICKBACK:
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
sudden 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 personal injury. Do not
rely exclusively upon the safety devices
built into your saw. As a chain saw user,
you should take several steps to keep your
cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/
or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below:
• Maintain a firm grip, with thumbs
and fingers encircling 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, ff proper precautions are taken.
Do not let go of the chain saw.
• Do not overreach and do not cut above
chest 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 tow 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
articutar 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 toot 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 tog 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
zLWARNING:
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
