Important Safety Instructions

WARNING: 

Read all instructions before operating product. Failure to follow all instructions listed below 

may result in electric shock, fire and/or serious injury.

READ ALL INSTRUCTIONS

Double Insulation

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.

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.

CAUTION:

 WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS. Repair or replace damaged cords.

Safety Instructions For All Tools

This miter saw accepts the D

E

WALT worklight and laser attachments.

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. 

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. 

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"). 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. If your product is 

equipped with a cordset, use only 3-wire extension cords that have 3-prong grounding-type plugs and 3-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 gage. The smaller the gage number, the heavier the 

cord.

 • 

CHECK for DAMAGED PARTS.

 Before further use of the tool, a guard or other part that is damaged should 

be carefully checked to determine that it will operate properly and perform its intended function—check for 

alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions 

that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced. 

Do not use tool if switch does not turn it on and off.

 • 

USE RECOMMENDED ACCESSORIES. 

Use only accessories that are recommended by the manufacturer for 

your model. Accessories that may be suitable for one tool may be hazardous when used on another tool. 

Consult the instruction manual for recommended accessories. The use of improper accessories may cause 

risk of injury to persons.

 • 

NEVER STAND ON TOOL.

 Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally 

contacted.

 • 

NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF.

 Don’t leave tool until it comes to a 

complete stop. Serious injury can result.

 • 

DO NOT OPERATE ELECTRIC TOOLS NEAR FLAMMABLE LIQUIDS OR IN GASEOUS OR EXPLOSIVE 

ATMOSPHERES.

 Motors in these tools may spark and ignite fumes.

 • 

STAY ALERT, WATCH WHAT YOU ARE DOING, AND USE COMMON SENSE. DO NOT USE THE MACHINE 

WHEN YOU ARE TIRED OR UNDER THE INFLUENCE OF DRUGS or ALCOHOL

. A moment of inattention while 

operating power tools may result in injury.

Additional Safety Rules For Miter Saws

WARNING: 

Do not allow familiarity (gained from frequent use of your saw) to replace safety rules. Always 

remember that a careless fraction of a second is sufficient to inflict severe injury.
 • 

DO NOT OPERATE THIS MACHINE 

until it is completely assembled and installed according to the 

instructions. A machine incorrectly assembled can cause serious injury.

 • 

OBTAIN ADVICE

 from your supervisor, instructor, or another qualified person if you are not thoroughly familiar 

with the operation of this machine. Knowledge is safety.
