SAVE THESE INSTRUCTIONS
WARNING: FOLLOW ALL WIRING CODES and recommended electrical connections to
prevent shock or electrocution.
Double Insulation
If saw is of double-insulated construction, read the following instructions.
This symbol
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 thru-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 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

• DO NOT FORCE TOOL. It will do the job better and be safer at the rate for which it was
designed.
• USE THE 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 OVERREACH. Keep proper footing and balance at all times. Loss of balance
may cause personal injury. Do not attempt to retrieve materials near the blade on the saw
table while the blade is spinning.

• 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.
maintained blades and machines can further damage the blade or machine and/or
cause injury.
• USE PROPER EXTENSION CORD. 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. 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.
