WARNING:
Some dust created by power cutting 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.
Y our 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.

parts, breakage of parts and any other condition that may affect the

power tool’s operation. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained power tools.
◾
Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
◾
Use the power tool,accessoriesand toolbits,etc.in accordance with
these instructions, taking into account the working conditions and the
work to be performed
.Use of the powertoolfor operationsdifferentfrom those
intended could result in a hazardous situation.
BATTERY TOOL USE AND CARE
◾
Recharge only with the charger specified by the manufacturer. A charger
that is suitable for one type of battery pack may create a risk of fire when used
with another battery pack.
◾
Use battery operated chain saws only with specifically designated
battery packs.
Use of any other battery packs may create a risk of injury
and fire.
◾
When the battery pack is not in use, keep it away from other metal
objects, like paper clips, coins, keys, nails, screws or other small metal
objects that can make a connection from one terminal to another.
Shorting the battery terminals together may cause burns or a fire.
◾
Under abusive conditions,liquid may be ejectedfrom the battery;
avoid contact. If contact accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the
battery may cause irritation or burns.
 Battery powered chain saws do not have to be plugged into an electrical
outlet; therefore, they are always in operating condition. Be aware of possible
hazards when not using your battery powered chain saws or when changing
accessories. Following this rule will reduce the risk of electric shock, fire, or
serious personal injury.
 Do not charge the battery pack outdoors.

 Use only the charger supplied by the manufacturer to recharge.

CAUSES AND OPERATOR
PREVENTION OF KICKBACK
(Fig. 1, 2, 3 & 4)
Kickbackmayoccur whenthe nose or
tip of the guide bar touches an
object, or when the wood closes in and
pinchesthe sawchaininthecut.
Tip contact in some cases may cause a
sudden reverse reaction,kicking the
guide bar up and back towards he
operator.
Pinching the saw chain along the top of
theguidebar maypush theguide
bar
rapidly back towards the operator.
Either of these reactions may cause
youto losecontrolofthesaw,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 bytaking properprecautions
as
given below:

◾
Maintain a firm grip, with
thumbs and fingersencircling
the chain saw handles, with
both hands on the saw and
position your body and arm to
allow you to resist kickback
forces (Fig. 4).
Kickback
forces
can be controlled bythe
operator,if
proper precautions are
taken. Do not
let go of the chain
saw.
◾
Donot overreachand do not cut above shoulder height. Thishelpsprevent
unintended tip contact and enables better control of the chain saw in unexpected
situations.
◾
Only use replacement bars and chains specified by the manufacturer.
Incorrectreplacementbarsandchainsmay causechainbreakageand/orkickback.
◾
Follow the manufacturer’s sharpening and maintenance instructions for the
saw chain.
Decreasing the depth gauge height can lead to increased kickback.
◾
Make sure that the area in which you are cutting is free from
obstructions. Donotlet the nose ofthe guidebar contactalog,branch,fence,
orany otherobstructionthatcouldbehitwhileyouareoperatingthe saw.
◾
Always cut with the unit running at full speed. Fully squeeze the switch
trigger and maintain cutting speed.
◾
With a basic understanding of kickback, you can reduce or eliminate the
element of surprise. Sudden surprise contributes to accidents.
◾
