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. 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 insulation system is for added protection against injury resulting from a possible electrical
insulation failure within the tool.
ACAUTION:
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
This miter saw accepts the DEWALT 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 $12.6 ($3.19) 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" (152 mm)].
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 gauge. The smaller the gauge number, the heavier the
cord.

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.
STABILITY. Make sure the miter saw is placed on a secure supporting surface and does not
slip or move during use. If the mobility kit is installed, raise the moveable caster(s) so saw is in
its stationary position.
FOLLOWALL
WIRING CODES and recommended electrical connections to prevent shock or
electrocution. Protect electric supply line with at least a 15 ampere time-delay fuse or a circuit
breaker."
MAKE CERTAIN the blade rotates in the correct direction. The teeth on the blade should point
in the direction of rotation as marked on the saw.
TIGHTEN ALL CLAMP HANDLES, knobs and levers prior to operation. Loose clamps can
cause parts or the workpiece to be thrown at high speeds.
BE SURE all blade and blade clamps are clean, recessed sides of blade clamps are against
blade and arbor screw is tightened securely. Loose or improper blade clamping may result in
damage to the saw and possible personal injury.
• ALWAYS USE A SHARP BLADE. Check the blade to see if it runs true and is free from
vibration. A dull or a vibrating blade can cause damage to the machine and/or serious injury.
DO NOT OPERATE ON ANYTHING OTHER THAN THE DESIGNATED
VOLTAGE for the
saw. Overheating, damage to the tool and personal injury may occur.
DO NOT WEDGE ANYTHING AGAINST THE FAN to hold the motor shaft. Damage to tool
and possible personal injury may occur.

machine or blade and/or serious injury.
• ALLOW THE MOTOR TO COME TO FULL SPEED prior to starting cut. Starting the cut too
soon may cause damage to the machine or blade and/or serious injury.
NEVER CUT FERROUS METALS (Those with any iron or steel content) or masonry. Either of
these can cause the carbide tips to fly off the blade at high speeds causing serious injury.
DO NOT USEABRASIVE
WHEELS. The excessive heat and abrasive particles generated by
them may damage the saw and cause personal injury.
NEVER have any part of your body in line with the path of the saw blade. Personal injury will
OCCUr.
NEVER apply blade lubricant to a running blade. Applying lubricant could cause your hand to
move into the blade resulting in serious injury.
DO NOT place either hand in the blade area when the saw is connected to the power source.
Inadvertent blade activation may result in serious injury.
DO NOT PERFORM FREE-HAND
OPERATIONS
(workpiece not supported by table and
fence). Hold the work firmly against the fence and table. Free-hand operations on a miter saw
could cause the workpiece to be thrown at high speeds, causing serious injury.
NEVER REACHAROUND
orbehind the saw blade. A blade can cause serious injury.
DO NOT reach underneath the saw unless it is unplugged and turned off. Contact with saw
blade may cause personal injury.
SECURE THE MACHINE
TO A STABLE SUPPORTING SURFACE. Vibration can possibly
cause the machine to slide, walk, or tip over, causing serious injury.
USE ONLY CROSSCUT SAW BLADES recommended for miter saws. For best results, do
not use carbide tipped blades with hook angles in excess of 7 degrees. Do not use blades with
deep gullets. These can deflect and contact the guard, and can cause damage to the machine
and/or serious injury.
USE ONLY BLADES OF THE CORRECT SIZE AND TYPE specified for this tool to prevent
damage to the machine and/or serious injury.
INSPECT BLADE FOR CRACKS or other damage prior to operation. A cracked or damaged
blade can come apart and pieces can be thrown at high speeds, causing serious injury. Replace
cracked or damaged blades immediately.
CLEAN THE BLADE AND BLADE CLAMPS prior to operation. Cleaning the blade and
blade clamps allows you to check for any damage to the blade or blade clamps. A cracked
or damaged blade or blade clamp can come apart and pieces can be thrown at high speeds,
causing serious injury.
DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic
guard. The polycarbonate material used in the guard is subject to attack by certain chemicals.
• ALWAYS USE THE KERF PLATE AND REPLACE THIS PLATE WHEN DAMAGED. Small
chip accumulation under the saw may interfere with the saw blade or may cause instability of
workpiece when cutting.
USE ONLY BLADE CLAMPS specified for this tool to prevent damage to the machine and/or
serious injury.
CLEAN THE MOTOR AIR SLOTS of chips and sawdust. Clogged motor air slots can cause
the machine to overheat, damaging the machine and possibly causing a short which could
cause serious injury.
KEEP ARMS, HANDS, AND FINGERS away from the blade to prevent severe cuts. Clamp
all workpieces that would cause your hand to be within [within 6" (152 mm)] of the saw blade.
NEVER LOCK THE SWITCH IN THE "ON" position. Severe personal injury may result.
TURN OFF THE MACHINE and allow the blade to come to a complete stop before raising
the arm and prior to cleaning the blade area, removing debris in the path of the blade, before
servicing or adjusting tool. A moving blade can cause serious injury.
