Definitions: Safety Guidelines 
The definitions below describe the level of severity for each signal word. Please read the 
manual and pay attention to these symbols.
 DANGER: Indicates an imminently hazardous situation which, if not avoided, will 
result in death or serious injury.
 WARNING: Indicates a potentially hazardous situation which, if not avoided, could 
result in death or serious injury.
 CAUTION: Indicates a potentially hazardous situation which, if not avoided, may 
result in minor or moderate injury.

Important Safety Instructions
 WARNING! Read all safety warnings and all instructions. Failure to follow the 
warnings and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS 
FOR FUTURE REFERENCE
Double Insulation
Double insulated tools are constructed throughout with two separate layers of electrical 
insulation or one single layer of reinforced 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.
NOTE: Double insulation does not take the place of normal safety precautions when 
operating this tool. The secondary insulation system is for protection against injury resulting 
from a possible failure of the primary insulation within the tool.
CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS. Repair or 
replace damaged cords.
Polarized Plugs
Polarized plugs (one blade is wider than the other) are used on equipment to reduce the risk 
of electric shock. When provided, this plug will fit in the polarized outlet only one way. If the 
plug does not fit fully in 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. 
Safety Instructions for All Tools
WARNING: To reduce the risk of eye injury, ALWAYS use eye protection when 
operating the miter saw.
•  KEEP GUARD IN PLACE and in working order.
•  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.
•  DON’T 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.
•  WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, 
bracelets, or other jewelry which may get caught in moving parts. Nonslip footwear is 
recommended. Wear protective hair covering to contain long hair.
•  ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety glasses. Also 
use face or dust mask if cutting operation is dusty. 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.
•  SECURE THE WORKPIECE. Use clamps or a vise to hold the workpiece on the table 
and against the fence or when your hand will be dangerously close to the blade within 6" 
(152mm). It is safer than using your hand and it frees both hands to operate tool. 
•  DON’T OVERREACH. Keep proper footing and balance at all times. Loss of balance may 
cause personal injury.
•  MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest 
performance. Follow instructions for lubricating and changing accessories. Poorly 
maintained tools and machines can further damage the tool 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. An accidental start-up can cause 
injury. Do not touch the plug’s metal prongs when unplugging or plugging in the cord. 
•  REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure that the switch is in 
the “OFF” position before plugging in the power cord. 
•  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.
Minimum Gauge for Cord Sets

120V 25 (7.6) 50 (15.2) 100 (30.5) 150 (45.7)
