SAFETY INSTRUCTIONS AND
WARNIN S FOR CHAIN SAWS
• Keep Work Area Clean -Cluttered areas invite injuries. Do not
start cutting until you have a clear work area, secure footing, and a
planned retreat path from the falling tree.
• Consider Work Area Environment - Use extreme caution when
cutting small size brush and saplings because the slender material
may catch the saw chain and be whipped toward you or pull you off
balance. When cutting a limb that is under tension be alert for spring
back so that you will not be struck when the tension in the wood
fibers is released. Do not expose chain saw to rain or snow. Do not
use chain saw in damp or wet locations or while it is raining or
snowing. Do not use chain saw in the presence of flammable liquids
or gases or enclosed concentrations of dust. Cut only when visibility
and light are sufficient to see clearly
• Keep Children, Bystanders, Visitors and Animals Away - Do
not let visitors contact chain saw. All visitors should be kept away
from work area.
• Store Idle Chain Saw - When not in use, chain saws should be
stored in a dry, and high or locked-up place - out of the reach of
children. When storing saw, always remove battery and use a
scabbard or carrying case.
• Don't Force Chain Saw - It will do the job better and safer at the
rate for which it was intended.
• Use Right Tool - Cut wood only. Don't use chain saw for purpose
not intended - for example - Don't use chain saw for cutting plastic,
metal, masonry, non-wood building materials.
• Dress Properly - Do not wear loose clothing or jewelry. Keep your
hair, clothing, and gloves away from moving parts. Loose clothing,
jewelry, or long hair can be caught in moving parts. Wear protective
hair covering to contain long hair. Air vents cover moving parts and
should be avoided. Protective non-slip gloves and non-skid footwear
are recommended when working outdoors. Always wear heavy,
long pants or other protection for your legs.
• Use Safety lasses - Also use safety footwear; snug fitting
clothing; protective gloves; proper hearing, respiratory, and head
protection.

IMPORTANT SAFETY INSTRUCTIONS
WARNIN : When using a battery operated chain saw, basic
safety precautions should always be followed to reduce risk of fire,
electric shock, and personal injury, including the following:
READ ALL INSTRUCTIONS
3

The following precautions should be followed to minimize
kickback:
(1.) Grip Saw irmly. 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.
saw stopped, finger off the switch, the guide bar and saw chain to
the rear. Remove battery and use scabbard when transporting saw.
• Maintain Chain Saw With Care - Keep tools sharp and clean for
better and safer performance. ollow instructions for lubricating and
changing accessories. Keep handles dry, clean, and free from oil
and grease.
• Disconnect Battery - Disconnect battery from chain saw when
not in use, before servicing, when tensioning chain, and when
changing accessories and attachments, such as saw chain.
• Stay Alert - Watch what you are doing. Use common sense. Do
not operate chain saw when you are tired, ill, or under the influence
of alcohol, drugs, or medication. Keep all parts of the body away
from the saw chain when the motor is operating. Before you start
the saw, make sure the saw chain is not contacting anything. When
cutting through wood, remember the chain saw cuts quickly and will
continue its downward or upward path. Stay out of its path.
• Check Damaged Parts - Before further use of the chain saw, any
part that is damaged should be carefully checked to determine that
it will operate properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts, breakage of
parts, mounting, and any other conditions that may affect its
operation. A guard or other part that is damaged should be properly
repaired or replaced by an authorized service center unless
otherwise indicated elsewhere in this instruction manual. Have
defective switches replaced by authorized service center. Do not
use chain saw if switch does not turn it on and off. Do not operate a
chain saw that is damaged, improperly adjusted, or is not
completely and securely assembled. Be sure that the saw chain
stops moving when the trigger is released.
• uard Against Kickback
WARNIN : 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.
4

Kickback Safety Features
WARNIN : 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 uide 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.
•Before you start chain saw, make sure saw chain is not
contacting any object.
•Do not operate a chain saw with one hand! Serious injury to
the operator, helpers, or bystanders may result from one
handed operation. Achain saw is intended for two-handed use only.
•Keep the handles dry, clean, and free of oil or grease.
•Do not allow dirt, debris, or sawdust to build up on the motor
or outside air vents.
•Stop the chain saw before setting it down.
•Do not cut vines and/or small under brush.
5
•Use extreme caution when cutting small size brush and
saplings because slender material may catch the saw chain and
be whipped toward you or pull you off balance.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chemicals
known to the State of California to cause cancer, birth defects or
other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often
you do this type of work. To reduce your exposure to these
chemicals: work in a well ventilated area, and work with approved
safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.
•Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on the
skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse
dust, which may cause serious and permanent respiratory or
other injury. Always use NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure. Direct particles away
from face and body.
