IMPORTANT SAFETY INSTRUCTIONS

WARNING: Read all instructions before operating product. Failure to follow
all instructions listed below may result in electric shock, fi re 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. 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.

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

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'
(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 gage. The smaller the gage
number, the heavier the cord.

Not Recommended

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.

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.

FOLLOW ALL 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.

DO NOT force cutting action. Stalling or partial stalling of motor can cause damage. To the

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 USE ABRASIVE 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 REACH AROUND or behind 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 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.

PROPERLY SUPPORT LONG OR WIDE WORKPIECES. Loss of control of the workpiece

can cause injury.

NEVER cross arms in front of blade while using tool. Always make a dry run (unpowered)

before making a finish cut so that you can check the path of the blade or severe personal
injury may result.

THE BLADE GUARD MANUALLY UNLESS THE SAW IS
TURNED OFF.
NOTE: Certain special cuts will require that you manually
raise the guard. See section on cutting base molding up to
3-7/8' high (page 10).
The front section of the guard is louvered for visibility
while cutting. Although the louvers dramatically reduce
flying debris, they are openings in the guard and safety
glasses should be worn at all times when viewing through
the louvers.

AUTOMATIC ELECTRIC BRAKE (120 VOLT ONLY)
Your saw is equipped with an automatic electric blade
brake which stops the saw blade within 5 seconds of trig-
ger release. This is not adjustable.
On occasion, there may be a delay after trigger release to
brake engagement. On rare occasions, the brake may not
engage at all and the blade will coast to a stop.
If a delay or “skipping” occurs, turn the saw on and off 4 or
5 times. If the condition persists, have the tool serviced by
an authorized D

E

Walt service center.

Always be sure the blade has stopped before removing it
from the kerf. The brake is not a substitute for guards or for
ensuring your own safety by giving the saw your complete
attention.

Brushes

DISCONNECT PLUG FROM POWER SUPPLY
Inspect carbon brushes regularly by unplugging tool,
removing the brush inspection cap (Figure 3) and with-
drawing the brush assembly. Keep brushes clean and slid-
ing freely in their guides. Always replace a used brush in
the same orientation in the holder as it was prior to its
removal. Carbon brushes have varying symbols stamped
into their sides, and if the brush is worn down to the line
closest to the spring, they must be replaced. Use only
identical D

E

WALT brushes. Use of the correct grade of

brush is essential for proper operation of electric brake.
New brush assemblies are available at D

E

WALT service

centers. The tool should be allowed to “run in” (run at no
load) for 10 minutes before use to seat new brushes. The
electric brake may be erratic in operation until the brushes
are properly seated (worn in).
While “running in” DO NOT TIE, TAPE, OR OTHERWISE
LOCK THE TRIGGER SWITCH ON. HOLD BY HAND
ONLY.

Operation

Plug the saw into any household 60 Hz power source.
Refer to the nameplate for voltage. Be sure the cord will
not interfere with your work.

SWITCH
To turn the saw on, depress the trigger switch as shown in
Figure 15. To turn the tool off, release the switch. There is
no provision for locking the switch on, but a hole is provid-
ed in the trigger for insertion of a padlock to lock the saw
off.

CUTTING WITH YOUR SAW
NOTE:
Although this saw will cut wood and many non-fer-
rous materials, we will limit our discussion to the cutting of
wood only. The same guidelines apply to the other
materials. DO NOT CUT FERROUS (IRON AND STEEL)
MATERIALS OR MASONRY WITH THIS SAW.
Do not
use any abrasive blades.

CROSSCUTS
Cutting of multiple pieces is not recommended but can be
done safely by ensuring that each piece is held firmly
against the table and fence. A crosscut is made by cutting
wood across the grain at any angle. A straight crosscut is
made with the miter arm at the zero degree position. Set
the miter arm at zero, hold the wood on the table and firm-
ly against the fence. Turn on the saw by squeezing the trig-
ger switch as shown in Figure 15.
When the saw comes up to speed (about 1 second) lower
the arm smoothly and slowly to cut through the wood. Let
the blade come to a full stop before raising arm.
Miter crosscuts are made with the miter arm at some angle
other than zero. This angle is often 45 degrees for making
corners, but can be set anywhere from zero to 48 degrees
left or right. After selecting the desired miter angle, be sure
to tighten the miter clamp knob. Make the cut as described
above.

BEVEL CUTS
A bevel cut is a crosscut made with the saw blade at a
bevel to the wood. In order to set the bevel, loosen the
bevel clamp knob and move the saw to the left as desired.
(It is necessary to move the left side of the fence to allow
clearance). Once the desired bevel angle has been set,
tighten the bevel clamp knob firmly.
