General Safety Rules
WARNING: Read all instructions before operating product. Failure to follow all
instructions listed below may result in electric shock, fire and/or serious injury.
SAVE THESE INSTRUCTIONS
WARNING: FOLLOW ALL WIRING CODES and recommended electrical connections
to prevent shock or electrocution.
Grounding Instructions
If saw is of grounded construction, read the following instructions.
DANGER: SHOCK HAZARD. THIS MACHINE MUST BE GROUNDED WHILE IN USE.
SERIOUS INJURY COULD RESULT.
ALL GROUNDED, CORD-CONNECTED MACHINES
In the event of a malfunction or breakdown, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock. This machine is equipped with
an electric cord having an equipment-grounding conductor and a grounding plug. The
plug must be plugged into a matching outlet that is properly installed and grounded in
accordance with all local codes and ordinances. Do not modify the plug provided - if it
will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper
connection of the equipment-grounding conductor can result in risk of electric shock.
The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment-grounding conductor. If repair or replacement of the
electric cord or plug is necessary, do not connect the equipment-grounding conductor
to a live terminal. Check with a qualified electrician or service personnel if the grounding
instructions are not completely understood, or if in doubt as to whether the machine is
properly grounded. Use only three-wire extension cords that have three-prong grounding
type plugs and matching three-conductor receptacles that accept the machine's plug, as
shown in Figure A. Repair or replace damaged or worn cord immediately.
GROUNDED, CORD-CONNECTED MACHINES INTENDED FOR USE ON A SUPPLY
CIRCUIT HAVING A NOMINAL RATING LESS THAN 150 VOLTS
If the machine is intended for use on a circuit that has an outlet that looks like the one
illustrated in Fig. A, the machine will have a grounding plug that looks like the plug
illustrated in Fig. A. A temporary adapter, which looks like the adapter illustrated in Fig.
B, may be used to connect this plug to a matching two-conductor receptacle as shown
in Fig. B if a properly grounded outlet is not available. The temporary adapter should be
used only until a properly grounded outlet can be installed by a qualified electrician. The
green-colored rigid ear, lug, and the like, extending from the adapter must be connected
to a permanent ground such as a properly grounded outlet box. Whenever the adapter
is used, it must be held in place with a metal screw. DO NOT use a sheet metal screw.

DANGER: IN ALL CASES, MAKE CERTAIN THAT THE RECEPTACLE IN QUESTION IS
PROPERLY GROUNDED. IF YOU ARE NOT SURE, HAVE A QUALIFIED ELECTRICIAN
CHECK THE RECEPTACLE.
Double Insulation
If saw is of double-insulated construction, read the following instructions.
This symbol represents double insulated construction. Double insulated tools are
constructed throughout with two separate layers of electrical insulation or one double
thickness of insulation between you and the tool's electrical system. Tools built with this
insulation system are not intended to be grounded. As a result, your tool is equipped with a
two prong plug which permits you to use extension cords without concern for maintaining a
ground connection. Repair or replace damaged or worn cord immediately
NOTE: Double insulation does not take the place of normal safety precautions when
operating this tool. The insulation system is for added protection against injury resulting from
a possible electrical insulation failure within the tool.

POLARIZED PLUGS

To reduce the risk of electric shock, this equipment has a polarized 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 into the outlet, reverse the plug.
If it still does not fit, contact a qualified electrician to install the proper
outlet. Do not change the plug in any way.
Important Safety Instructions
• TO REDUCE THE RISK OF KICKBACK AND OTHER INJURIES, use all components
of the guarding system (blade guard assembly, riving knife and anti-kickback) for every
operation for which they can be used including all through cutting.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that
keys and adjusting wrenches are removed from spindle before turning tool on. Tools,
scrap pieces, and other debris can be thrown at high speed, causing injury.
• KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
• DO NOT USE THE MACHINE IN A DANGEROUS ENVIRONMENT. The use of power
tools in damp or wet locations or in rain can cause shock or electrocution. Keep your
work area well-lit to avoid tripping or placing arms, hands, and fingers in danger.
• KEEP CHILDREN AWAY. All visitors should be kept at a safe distance from work area.
Your shop is a potentially dangerous environment.
• MAKE WORKSHOP CHILDPROOF with padlocks, master switches, or by removing
starter keys. The unauthorized start-up of a machine by a child or visitor may result in
injury.
