WORK AREA
[] Keepyourwork area clean andwell lit. Cluttered
benchesand dark areasinviteaccidents_
B Do notoperatepowertools inexplosive atmo-
spheres,suchas In thepresence offlammableliq-
uids,gases,or dust. Powertoolscreatesparkswhich
may ignitethedust or fumes.
[] Keep bystanders,children,andvisitorsawaywhile
operatinga powertoot.Distractionscan causeyouto
losecontrol,
ELECTRICAL SAFETY
[] Double insulated tools are equtpped with a polar-
ized plug (one blade is wider than the other), This
plug will fit in a polarized outlet only one way. If the
plug does not fit fully inthe outlet, reverse the plug,
If it still does not fit, contact a qualified electrician
to install a polarized outlet. Do not change the plug
in anyway. Double Insulation [] eliminatesthe need
for the three-wire grounded power cord and grounded
power supply system.
= Avoid body contact with grounded surfaces such as
pipes, radiators, ranges and refrigerators. There is an
increased risk of electric shock ifyour body is grounded°
II Don't expose power tools to rain or wet conditions.
Water entering a power tool will increase the riskof
electricshock,
[] Do not abuse the cord. Never use the cord to carry
the tools or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged
cords increase the risk of eiectdc shock.
[] When operating a power tool outside, use an outdoor
extension cord marked "W-A" or WV".These cords
are ratedfor outdoor use and reduce the risk of electric
shock.
PERSONAL SAFETY
[] Stayalert,watch what youare doingandusecom-
mon sensewhen operatinga powertool Do not

[] Dressproperly.Donot wear looseclothingor
jewelry.Containlonghair. Keep yourhair,clothing,
and glovesaway frommovingparts.Looseclothes,
jewelry,orlong haircanbe caught inmovingparts.
• Avoidaccidentalstarting. Be sureswitchIsoff
before plugging In. Carrying tools with yourfinger on
the switch or plugging in tools that have the switch on
invitesaccidents.
• Remove adjusting keys or wrenches before turning
the too! on. A wrench or a key that is left attached to a
rotating par_of the tool may result in personal lnjury.
I Do not overreach. Keep proper footing and balance
at all times, Proper footing and balance enables better
control of the too_in unexpectedmtualicnso
• Use safety equipment. Always wear eye protection.
Dust mask, non-skid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions
• Do not wear loose clothing or Jewelry. Contain long
hair. Loose clothes, jewelry, or long haircan be drawn
into air vents.
[] Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected siluations.
TOOL USE AND CARE
B Use clamps or other practical way to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable and
may lead to loss of control
[] Do not force tool, Use the correct tool for your ap-
plication. The correct tool will do the job better and
safer at the rate for whJch itis designed.
u Do not use tool if switch does not turn it on or off.
Any t_l that cannot be controlled w(th the switch is
dangerous and must be repaired,
[] Disconnect the plug from power source before
making any adjustrnentsj changing accessories,
or storing the tool. Such preventive safety measures
reduce the risk of starting the too! accidentally.
[] Store Idle tools out of reach of children and other
untrained persons. Tools are dangerous Inthe hands
of untrained users.
[] Maintain tools with care. Keep cutting tools sharp
and clean. Property maintained tows with sharpcut-
ting edges are tess likely to bind and are easier to
control.
[] Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that
may affect the tool's operation. If damaged, have
the tool serviced before using, Many accidents are
caused by poody maintainedtools,
[] Use cnhJaccessories that are recommended bythe
manufacturer for your model. Accessories that may
be suitable for one toot, may become hazardous when
used on another tool
I Keep the tool and its handle dry, clean and free
from og and grease. Always use a clean cloth when
clBaning_ Never use brake fluids, gasoline, petroleum-
based products, or any strongsolvents to clean your
too!. Following this rule will reduce the risk of loss of

Causes and Operator Prevention of Kickback:
Kickback is a sudden reaction to a pinched, bound, or
misaligned saw blade, causing an uncentre{ied saw te lift
up and out of the workpiece toward operator.
When theblade is pinched orbound t{ghtJybythe keffclesing
down, the blade sta(Is and the motor reaction drives the unit
rapidly back toward the eperaton
If the blade becomes twisted or misatigned in the cut, the
teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to c{Imb out ef the
kerr and jump back toward the operator,,
Kickback isthe result ofteol misuse and/or incorrect operating
procedures or conditions and can beavoided by taking proper
precautions, as given below:
[] Maintain a firm grip with both hands on the saw and
position your body and _rm to allow ye_ to resist
kickback {orcee. Kickback forces can be centro{{ed by
the operator, if proper precautions are taken.
u When blade is binding, or when interrupting a cut
for any mason, release the trigger and hotd the saw
motionless in the material until the blade comes to a
complete stop. Never attempt to remove the saw from
the work or pull the saw backward while the blade is
in motion, or KICKBACK may occur. Investigate and
take corrective actions to eliminate the cause of blade
binding,
[] When restarting a saw in the workpiece, center the
saw blade in the kerf and check that saw teeth are
not engaged Into the material, tf saw blade is binding,
it may walk up or KICKBACK from the workpiece as the
saw isrestarted.
• St_pport large panels to minimize the risk o1 blade
pinching and KICKBACK. Large panels tend to sag
under their own weight. Supports must be placed under
the panel on both sides, near the iine ofcut and near the
edge of the panel.

m Make sure your extension cord is in good condition,
When using an extension cord, be sure to use one
heavy enough to carry the current your product
will draw. A wire gage sLze(A.W.G.) of at least 12 is
recommended for an extension cord 50 feet or
tess in length, A cord exceeding 100 feet is not
recommended, tf in doubt, use the next heavier gage.
The smaller the gage number, the heavier the cord. An
undersized cord wiltcause a drop in line voltage resulting
in loss of power and overheating.
I Inspect for and remove all nails from lumber before
using this tool, Folio'wing this rule wilt reduce the risk of
seriouspersonal injury.
Laser Guide Warnings:
The laser guide radiation used inthe Craftsman circularsaw
is Class Ilia with maximum 5mW and 650nm wavelengths,

EXTENSION CORDS
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the tool will draw. An
undersized cord will cause a drop in tine voltage, resulting
in overheating and loss of power. Use the chart to deter-
mine the minimum wire size required inan extens(on cord°
Only round jacketed cords listed by Underwriter's Labora-
tories (UL) should be used,
When working outdoors with a tool, use an extension
cord that is designed for outside use. This type of cord is
designated with "WA" on the cord's jacket.
Before using any extension cord, inspect it for toose or
exposed wires and cut or worn insulation.
