WARNING: Read all safety warnings and all instructions provided with

your Power Unit (BDCDMT112, BDCDMT120, or BDEDMT) before using this attachment. Failure to follow the warnings and instructions may result in

electric shock, re and/or serious injury.

SPECIFIC SAFETY RULES

DANGER: Keep hands away from cutting area and the blade. Keep your second hand

on auxiliary handle or motor housing. If both hands are holding the saw, they cannot be cut

by the blade. b) Do not reach underneath the workpiece. The guard cannot protect you from the blade

below the workpiece.

c) Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the

blade teeth should be visible below the workpiece.

d) Never hold piece being cut in your hands or across your leg. Secure the workpiece to

a stable platform. It is important to support the work properly to minimize body exposure,

blade binding, or loss of control.

e) Hold power tool by insulated gripping surfaces when performing an operation where

the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will

also make exposed metal parts of the power tool “live” and shock the operator.

f) When ripping always use a rip fence or straight edge guide. This improves the accuracy

of cut and reduces the chance of blade binding.

g) Always use blades with correct size and shape (diamond versus round) of arbour holes. Blades

that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.

h) Never use damaged or incorrect blade washers or bolt. The blade washers and bolt

were specially designed for your saw, for optimum performance and safety of operation.

CAUSES AND OPERATOR PREVENTION OF KICKBACK

• Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an

uncontrolled saw to lift up and out of the workpiece toward the operator.

• When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the

motor reaction drives the unit rapidly back toward the operator.

• If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade

can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.

Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and

can be avoided by taking proper precautions as given below: a) Maintain a rm grip with both hands on the saw and position your arms to resist

kickback forces. Position your body to either side of the blade, but not in line with the blade. Kickback could cause the saw to jump backwards, but kickback forces can be

controlled by the operator, if proper precautions are taken.

b) When blade is binding, or when interrupting a cut for any reason, release the trigger

and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective actions to

eliminate the cause of blade binding.

c) When restarting a saw in the workpiece, center the saw blade in the kerf and check

that saw teeth are not engaged into the material. If saw blade is binding, it may walk up

or kickback from the workpiece as the saw is restarted.

d) Support large panels to minimize the risk of blade pinching and kickback. Large

panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.

e) Do not use dull or damaged blades. Unsharpened or improperly set blades produce

narrow kerf causing excessive friction, blade binding and kickback.

f) Blade depth and bevel adjusting locking levers must be tight and secure before

making cut. If blade adjustment shifts while cutting, it may cause binding and kickback.

g) Use extra caution when sawing into existing walls or other blind areas. The protruding

blade may cut objects that can cause kickback.

LOWER GUARD SAFETY INSTRUCTIONS

a) Check lower guard for proper closing before each use. Do not operate the saw if lower

guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If saw is accidentally dropped, lower guard may be bent. Raise the

lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.

b) Check the operation of the lower guard spring. If the guard and the spring are not

operating properly, they must be serviced before use. Lower guard may operate

sluggishly due to damaged parts, gummy deposits, or a buildup of debris.

c) Lower guard should be retracted manually only for special cuts such as “plunge cuts”

and “compound cuts.” Raise lower guard by retracting handle and as soon as blade

enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically.

d) Always observe that the lower guard is covering the blade before placing saw down

on bench or oor. An unprotected, coasting blade will cause the saw to walk backwards,

cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.

ADDITIONAL SAFETY INSTRUCTIONS

• Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss

of control.

• Keep your body positioned to either side of the blade, but not in line with the saw blade. KICKBACK could cause the saw to jump backwards (see Causes and Operator Prevention of Kickback and KICKBACK).

• Avoid cutting nails. Inspect for and remove all nails from lumber before cutting.

• Always make sure nothing interferes with the movement of the lower blade guard.

• Accessories must be rated for at least the speed recommended on the tool warning

label. Wheels and other accessories running over rated speed can y apart and cause injury. Accessory ratings must always be above tool speed as shown on tool nameplate.

• Always make sure the saw is clean before using.

• Stop using this saw and have it properly serviced if any unusual noise or abnormal operation

occurs.

• Always be sure all components are mounted properly and securely before using tool.

• Always handle the saw blade with care when mounting or removing it or when removing the

diamond knockout.

• Always wait until the motor has reached full speed before starting a cut.

• Always keep handles dry, clean and free of oil and grease. Hold the tool rmly with both

hands when in use.

• Always be alert at all times, especially during repetitive, monotonous operations. Always be sure of position of your hands relative to the blade.

• Stay clear of end pieces that may fall after cutting off. They may be hot, sharp and/or heavy. Serious personal injury may result.

• Replace or repair damaged cords. Make sure your extension cord is in good condition. Use only 3-wire extension cords that have 3-prong grounding-type plugs and 3-pole receptacles that accept the tool’s plug.

• An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that

is 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line

voltage resulting in loss of power and overheating. When using more than one extension to

make up the total length, be sure each individual extension contains at least the minimum wire size. 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.

CAUTION: Blades coast after turn off. Serious personal injury may result.

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 proper eye protection. All users and bystanders must wear

proper eye protection that conforms to ANSI Z87.1.

WARNING: ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety

glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS wear certied safety equipment:

• ANSI Z87.1 eye protection (CAN/CPA Z94.3),

• ANSI S12.6 (S3.19) hearing protection,

• NOSH/OSHA respiratory protection.

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

construction activities contains chemicals known in 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 (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 lter 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 disburse 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. Always operate tool in well-ventilated area and provide for proper dust removal. Use dust collection system wherever possible.

TO REDUCE THE RISK OF KICKBACK

• Keep a firm grip on saw with both hands at all times.

• Stay alert – exercise control.

• Support long overhanging materials. As the material is cut and weakens, it will sag, causing a

pinched blade.

• Support large panels as shown (FigureC). Material supported only at the ends (Figure B) will lead to blade pinching.

• Avoid sawing overhead. Material can sag and will pinch blade.

• Insure that the material to be cut is clamped (Figure E) and solidly supported and balanced on a

strong, stable and level work surface. Support the work so that the wide portion of the saw shoe is on the portion of the material that doesn’t fall after the cut is made. Never hold cut off piece by hand (Figure D).

• Keep blades sharp and clean.

• Use fence or straight edge guide when ripping. Be careful as the cut off strip can sag or twist, closing the cut and pinching the blade, leading to KICKBACK.

• Don’t force tool. Wood variables such as knots, hardness, toughness, wetness, pressure

treated and freshly cut green lumber can heavily load the saw which can lead to stalling. Push the saw slower when this occurs.

• Don’t remove saw from work during a cut while the blade is moving.

• Allow saw to reach full speed before blade contacts material to be cut. Starting the saw with

the blade against the work or pushed forward into cut can lead to stalling or sudden backward movement of saw.

• Never attempt to lift saw when making a bevel cut. This leads to blade binding and stalling.

• Always secure work to prevent workpiece movement during cut.

• Do not try to force saw back on line if your cut begins to go off line. This can cause KICKBACK. Stop saw and allow blade to coast down to a stop. Withdraw from cut and start a new cut on

the line.

• Do not back up a rotating blade in the cut. Twisting the saw can cause the back edge of the

blade to dig into the material, climb out of the work and run back toward the operator.

• Avoid cutting nails. Inspect for and remove all nails from lumber before cutting.

LOWER BLADE GUARD

WARNING

guard is a safety feature which reduces the risk of serious personal injury. Never use the saw if the lower guard is missing, damaged, mis-assembled or not working properly. Do not rely on the lower blade guard to protect you under all circumstances. Your safety depends on following all warnings and precautions as well as proper operation of the saw. Check lower guard for proper closing before each use as outlined in Additional Safety Rules for Circular Saws. If the lower blade guard is missing or not working properly, immediately discontinue use of the saw, and take it to a qualied service dealer for possible repair.

: Laceration Hazard. The lower blade

WARNING: To minimize the risk of eye injury, always use eye protection. Carbide is a hard

but brittle material. Foreign objects in the work piece such as wire or nails can cause tips to crack or break. Only operate saw when proper saw blade guard is in place. Mount blade securely in proper rotation before using, and always use a clean, sharp blade.

WARNING: Do not cut ferrous metals (steel), masonry, glass or tile with this saw.

A dull blade will cause slow, inefficient cutting overload on the saw motor, excessive splintering, and could increase the possibility of kickback.
