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:
• 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 nose of the guide bar contact a log, branch,
ground or other obstruction.
• Do not extend 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 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.
Reduced 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 reduced-kickback
44
chain is a chain which has met kickback performance
requirements when tested on the representative sample of
chain saws.
Pole Saw Names and Terms
Drive Sprocket or Sprocket - The toothed part that drives
•
the saw chain.
Guide Bar - A solid railed structure that supports and guides
•
the saw chain.
Guide Bar Scabbard - Enclosure fitted over guide bar to
•
prevent tooth contact when saw is not in use.
Kickback - The backward or upward motion, or both of the
•
guide bar occurring when the saw chain near the nose of the
top area of the guide bar contacts any object such as a log or
branch, or when the wood closes in and pinches the saw chain
in the cut.
• Reduced Kickback Chain - A chain that complies with
the kickback performance requiremens. (when tested on a
representative sample of chain saws.
Reduced Kickback Guide Bar - A guide bar which has been
•
demonstrated to reduce kickback significantly.
• Replacement Saw Chain - A chain that complies with
kickback performance requirements when tested with specific
chain saws. It may not meet performance requirements when
used with other saws.
Saw Chain - A loop of chain having cutting teeth, that cut the
•
wood, and that is driven by the motor and is supported by the
guide bar.
• Spiked Bumper (Spike) - The pointed tooth or teeth for use
when pruning to pivot the saw and maintain position while
sawing.
switch - A device that when operated will complete or
•
interrupt an electrical power circuit to the motor of the chain
saw.
Switch Lockout - A movable stop that prevents the
•
unintentional operation of the switch until manually actuated.
Trimming (Pruning) - Process of cutting limbs from a tree.
•
Undercut - An upward cut from underside of a log or limb.
•
This is done while in normal cutting position and cutting with
top of guide bar.
Storage
1 . Store indoors. The best storage place is one that is cool and
dry away from direct sunlight, excess heat or cold and out of
the reach of children.
2 . Always reduce the tension off the chain again after
finishing work. The chain contracts as it cools down. If
tension is not reduced, it can damage the saw.
