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.

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.
• To change the cord set, contact your local dealer or authorized service center.
• 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.
• DO NOT FORCE TOOL. It will do the job better and be safer at the rate for which it was
designed.
• USE RIGHT TOOL. Don't force tool or attachment to do a job for which it was not
designed. Using the incorrect tool or attachment may result in personal injury.
– Do not use the saw blades if damaged or deformed;
– Use only manufacturer's recommended saw blades;
– Verify that the selection of the saw blade matches the material to be cut.
• USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition.
If your product is equipped with a cord set, use only three-wire extension cords that have
three-prong grounding-type plugs and three-pole receptacles that accept the tool's plug.
When using an extension cord, be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. The following table shows the correct size to use depending on
cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

• WEAR PROPER APPAREL. No loose clothing, gloves, neckties, rings, bracelets, or other
jewelry to get caught in moving parts. Non-slip footwear is recommended. Wear protective
hair covering to contain long hair. Air vents may cover moving parts and should also be
avoided.
• ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety glasses. Also
use face or dust mask if cutting operation is dusty. All users and bystanders MUST
ALWAYS wear certified safety equipment:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
• DO NOT OVERREACH. Keep proper footing and balance at all times. Loss of balance
may cause personal injury.
• MAINTAIN TOOLS WITH CARE. Keep blades sharp and clean for best and safest
performance. Follow instructions for lubricating and changing accessories. Poorly
maintained blades and machines can further damage the blade or machine and/or cause
injury.
• TURN THE MACHINE "OFF", AND DISCONNECT THE MACHINE FROM THE
POWER SOURCE before installing or removing accessories, before adjusting or
changing set-ups, when making repairs or changing locations. Do not touch the plug's metal
prongs when unplugging or plugging in the cord. An accidental start-up can cause injury.
