Important Safety Instructions

WARNING: When using electric tools, basic safety precautions should always be

followed to reduce risk of fire, electric shock, and personal injury, including the following:

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

• 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.

• KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.

• DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet

locations, or expose them to rain. Keep work area well lighted.

• KEEP CHILDREN AWAY. All visitors should be kept at a safe distance from work area.

• MAKE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter

keys.

• 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.

• WEAR PROPER APPAREL. No loose clothing, gloves, neckties, rings, bracelets, or other

jewelry to get caught in moving parts. Nonslip footwear is recommended. Wear protective
hair covering to contain long hair.

• ALWAYS WEAR SAFETY GLASSES. Also use face or dust mask if cutting operation is

dusty. Everyday eyeglasses have only impact resistant lenses, they are NOT safety glasses.

• SECURE WORK. Use clamps or vise when you cannot secure the workpiece on the table

and against the fence by hand or when your hand will be dangerously close to the blade
(within 6”).

• DON’T OVERREACH. Keep proper footing and balance at all times.

• MAI NT AI N TO OL S WITH CARE . Keep too ls sha rp and clean for best and safes t

performance. Follow instructions for lubricating and changing accessories.

• DISCONNECT TOOLS before servicing; when changing accessories such as blades, bits,

cutters, etc.

• REDUCE THE RI SK OF UNI NTE NTI ONAL STARTING. Make sure switch is in OFF

position before plugging in.

• USE RECOMMENDED ACCESSORIES. 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.

• CHECK 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.

• NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool
until it comes to a complete stop.

• DO NOT OPERATE ELECTRIC TOOLS NEAR FLAMMABLE LIQUIDS OR IN GASEOUS
OR EXPLOSIVE ATMOSPHERES. Motors in these tools may spark and ignite fumes.

• EXTENSION CORDS. 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 i n l ine voltage r esulting in l oss 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.

Additional Safety Rules For Miter Saws

CAUTION: FAILURE TO HEED THESE WARNINGS MAY RESULT IN PERSONAL

INJURY AND SERIOUS DAMAGE TO THE SAW.

• DO - Protect electric supply line with at least a 15 ampere time-delay fuse or a circuit breaker.

• DO - Make certain the blade rotates in the correct direction and that the teeth at the bottom
of the blade are pointing to the rear of the miter saw.

• DO - Be sure all clamp handles are tight before starting any operation.

• DO - Be sure all blade and clamp washers are clean and recessed sides of collars are
against blade. Tighten arbor screw securely.

• DO - Keep saw blade sharp.

• DO - Keep motor air slots free of chips and dirt.

• DO - Use blade guards at all times.

• DO - Keep hands out of path of saw blade.

• DO - Shut off power, disconnect cord from power source and wait for saw blade to stop
before servicing or adjusting tool.

• DO - Support long work with an outboard tool rest.

• DO NOT - Attempt to operate on anything but designated voltage.

• DO NOT - Operate unless all clamp handles are tight.

• DO NOT - Use blades larger or smaller than those which are recommended.

• DO NOT - Wedge anything against fan to hold motor shaft.

• DO NOT - Force cutting action. (Stalling or partial stalling of motor can cause major
damage. Allow motor to reach full speed before cutting.)

• DO NOT - Cut ferrous metals (Those with any iron or steel content) or any masonry.

• DO NOT - Use abrasive wheels. The excessive heat and abrasive particles generated by
them will damage the saw.

• DO NOT - Allow anyone to stand behind saw.

• DO NOT - Apply lubricants to the blade when it’s running.

• DO NOT - Place either hand in the blade area when the saw is connected to the power
source.

Electrical Connection

Be sure your power supply agrees with the nameplate marking. 120 volts, AC means that
your saw will operate on alternating current only. A voltage decrease of 10 percent or
more will cause a loss of power and overheating. All D

EWALT tools are factory tested. If

this tool does not operate, check the power supply.

CAUTION: Do not connect unit to electrical power source until complete instructions are

read and understood.

CAUTION: Wear appropriate personal hearing protection during use. Under some

conditions and duration of use, noise from this product may contribute to hearing loss.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter
out microscopic particles.

• Avoid pr olo nge d contact wit h dust from power san din g, saw ing, grinding,

drilling, and other construction activities. Wear protective clothing and wash
exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or
