ADDITIONAL INFORMATION 

regarding the safe and proper operation of power tools 

(i.e., a safety video) is available from the Power Tool Institute, 1300 Sumner Avenue, 

Cleveland, OH 44115-2851 (www.powertoolinstitute.com). Information is also available 

from the National Safety Council, 1121 Spring Lake Drive, Itasca, IL 60143-3201. Please 

refer to the American National Standards Institute ANSI 01.1 Safety Requirements for 

Woodworking Machines and the U.S. Department of Labor OSHA 1910.213 Regulations.

WARNING: 

 Cutting plastics, sap coated wood, and other materials may cause melted 

material to accumulate on the blade tips and the body of the saw blade, increasing the risk of 

blade overheating and binding while cutting.

WARNING: Always wear proper personal hearing protection that conforms to ANSI 

S12.6 (S3.19) during use. 

Under some conditions and duration of use, noise from this 

product may contribute to hearing loss.

 WARNING: 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.

 WARNING: 

Some dust created by power sanding, sawing, grinding, drilling, and other 

construction activities contains chemicals known to the State of California 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.

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 prolonged contact with dust from power sanding, sawing, 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 lay on the skin 

may promote absorption of harmful chemicals. 

 WARNING: 

Use of this tool can generate and/or disperse dust, which may cause serious 

and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory 

protection appropriate for the dust exposure. Direct particles away from face and body.
•  The label on your tool may include the following symbols. The symbols and their definitions 

are as follows:

V ...................... volts A ......................... amperes
Hz.................... hertz W ........................ watts

ONLY OPERATE WITH D

e

WALT FLEXVOLT BATTERIES OR WITH THE D

e

WALT 

CORDED POWER SUPPLY. 

Only connect the power supply cord to the designated 

voltage listed. 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.

  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 OR BLADES. 

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. 

• 

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 WARPED BLADES. 

Check to see if the blade runs true and is free from 

vibration. A vibrating blade can cause damage to the machine and/or 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. 

• 

KEEP GUARD IN PLACE 

and in working order.

• 

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.

• 

NEVER LOCK THE SWITCH IN THE “ON” POSITION.

 Severe personal injury 

may result.

• 

NEVER STAND ON TOOL. 

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

tool is unintentionally contacted.
