GENERAL POWER TOOL SAFETY WARNINGS

WARNING! Read all safety warnings and instructions

Failure to follow the warnings and instructions may result in

electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND

INSTRUCTIONS

FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) WORK AREA SAFETY

a) Keep work area clean and well lit. Cluttered or dark areas

invite accidents.

b) Do not operate power tools in explosive atmospheres,

such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or

fumes.

c) Keep children and bystanders away while operating a

power tool. Distractions can cause you to lose control.

2) ELECTRICAL SAFETY

a) Power tool plugs must match the outlet. Never modify

the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and

matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded surfaces

such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord for carrying,

pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or

entangled cords increase the risk of electric shock.

e) When operating a power tool outdoors, use an extension

cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

English

f) If operating a power tool in a damp location is unavoidable,

use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

3) PERSONAL SAFETY

a) Stay alert, watch what you are doing and use common

sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while

operating power tools may result in serious personal injury.

b) Use personal protective equipment. Always wear eye

protection. Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the switch is in

the off position before connecting to power source and/ or battery pack, picking up or carrying the tool. Carrying

power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the

power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at

all times. This enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery.

Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in

moving parts.

g) If devices are provided for the connection of dust

extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can

reduce dust-related hazards.

4) POWER TOOL USE AND CARE

a) Do not force the power tool. Use the correct power tool

for your application. The correct power tool will do the job

better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not turn it

on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or the

battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of

starting the power tool accidentally.

d) Store idle power tools out of the reach of children and

do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools

are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or binding

of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many

accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly maintained

cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits etc., in

accordance with these instructions taking into account the working conditions and the work to be performed.

Use of the power tool for operations different from those intended could result in a hazardous situation.

5) BATTERY TOOL USE AND CARE

a) Recharge only with the charger specified by the

manufacturer. A charger that is suitable for one type

English

of battery pack may create a risk of fire when used with another battery pack.

b) Use power tools only with specifically designated

battery packs. Use of any other battery packs may create a risk of injury and fire.

c) When battery pack is not in use, keep it away from

other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the

battery terminals together may cause burns or a fire.

d) Under abusive conditions, liquid may be ejected from

the battery, avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may

cause irritation or burns.

6) SERVICE

a) Have your power tool serviced by a qualified repair

person using only identical replacement parts. This will

ensure that the safety of the power tool is maintained.

ADDITIONAL SPECIFIC SAFETY RULES Safety Instructions for All Saws

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.

Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.

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.

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.

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.

When ripping always use a rip fence or straight edge guide.

This improves the accuracy of cut and reduces the

chance of blade binding.

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

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

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 operator.

Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

English

a) Maintain a firm grip with both hands on the saw and

position your body and arm to allow you to resist kickback forces. 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 the 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. Support 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 blade. 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 making a “Plunge Cut” into

existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.

Safety Instructions for Plunge-Type Saws

a) Check guard for proper closing before each use. Do

not operate the saw if guard does not move freely and enclose the blade instantly. Never clamp or tie the guard with the blade exposed. If saw is accidentally dropped,

guard may be bent. Check to make sure that guard moves freely and does not touch the blade or any other part, in all angles and depths of cut.

b) Check the operation and condition of the guard return

spring. If the guard and the spring are not operating properly, they must be serviced before use. Guard may

operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.

c) Assure that the guide plate of the saw will not shift while

performing the “plunge cut” when the blade bevel setting is not at 90°. Blade shifting sideways will cause binding and

likely kickback.

d) Always observe that the guard is covering the blade before

placing saw down on bench or floor. 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 for All Saws with Riving Knife

a) Use the appropriate riving knife for the blade being used.

For the riving knife to work, it must be thicker than the body of the blade but thinner than the tooth set of the blade.

b) Adjust the riving knife as described in this instruction

manual. Incorrect spacing, positioning and alignment can make the riving knife ineffective in preventing kickback.

English

c) Always use the riving knife except when plunge cutting.

Riving knife must be replaced after plunge cutting. Riving knife causes interference during plunge cutting and can create kickback. Model DC351 does not require removal of the riving knife because the riving knife retracts during a plunge cut.

d) For the riving knife to work, it must be engaged in the

workpiece. The riving knife is ineffective in preventing kickback during short cuts.

e) Do not operate the saw if riving knife is bent. Even a light

interference can slow the closing rate of a guard.

Additional Safety Instructions for Saws

• Wear ear protectors. Exposure to noise can cause hearing

loss.

• Wear a dust mask. Exposure to dust particles can cause

breathing difficulty and possible injury.

• Use only recommended blades. The saw is designed for use

with 6-1/2" (165 mm) diameter blades that have a 0.79" (20 mm) diameter bore. Blades must be rated for 6000 RPM operation (or higher).

• Never use abrasive cut-off wheels.

• 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).

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

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

lumber before cutting.

EXTENSION CORDS

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.

• Air vents often cover moving parts and should be avoided.

Loose clothes, jewellery or long hair can be caught in moving parts.

• Accessories must be rated for at least the speed recommended on the tool warning label. Accessories running over rated speed can fly apart and cause injury. Accessory ratings must always be above tool speed as shown on tool nameplate.

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.

English

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 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 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.

Workpiece Support

WARNING: Hands should be kept away from cutting area to

reduce the risk of injury.

WARNING: The power cord should be positioned clear of the

cutting area so that it will not get caught or hung up on the work and to prevent electric shock.

Figure 6 shows proper sawing position. Figure 7 shows an unsafe condition. To avoid kickback, DO support board or panel NEAR the cut. DON’T support board or panel away from the cut.

important to support the work properly and to hold the saw firmly to prevent loss of control which could cause personal injury. Figure 8 illustrates typical hand support of the saw.

Place the work with its “good” side – the one on which appearance is most important – down. The saw cuts upward, so any splintering will be on the work face that is up when you saw it.

DANGER: Risk of electrical shock. Keep the cord away from the

cutting area to prevent electrocution.

WARNING: If the guard binds or is sluggish, return the saw to

your nearest authorized D

EWALT service center for repair.

WARNING: For maximum protection, effective control of this

powerful saw requires two-handed operation. support the work properly and hold the saw firmly to prevent loss of control which could cause injury. Refer to Figure 8 for the proper way to hold the saw.

WARNING: Stay alert and maintain a firm grip on the saw.

Release the switch immediately if the blade binds or the saw stalls. Keep your blade sharp. Properly support panels (Fig. 6, 7). Use the track when ripping. DO NOT force the tool. DO NOT remove the saw from the workpiece while the blade is moving.

WARNING: To help reduce the risk of personal injury, always

clamp work. Don’t try to hold short pieces by hand! Remember to support cantilevered and over hanging material. Use caution when sawing material from below.

WARNING: Be sure that the saw is up to full speed before blade

contacts material to be cut. Starting the saw with blade against material to be cut or pushed forward into kerf can result in kickback and personal injury.

WARNING: ALWAYS secure the workpiece in such a manner

that it cannot move while sawing. For optimum results, clamp the workpiece bottom up.

WARNING: ALWAYS push the machine forwards. NEVER pull

the machine backwards towards you.

WARNING: ALWAYS use the clamp (Fig. 9, BB) to hold the track

to the workpiece.

English

CAUTION: Do not operate your tool on a current on which the voltage is not within correct limits. Do not operate tools rated AC only on DC current. To do so may seriously damage the tool.

1. Place the machine with the front part of the saw base on the workpiece.

2. Press the on/off switch to turn the saw on.

3. Push the plunge trigger (A) forward, press the saw down to set cutting depth and push it forward into cutting direction.

Push the saw forward at a speed which allows the blade to cut without laboring. Hardness and toughness can vary even in the same piece of material, and knotty or damp sections can put a heavy load on the saw. When this happens, push the saw more slowly, but hard enough to keep it working without much decrease in speed. Forcing the saw can cause rough cuts, inaccuracy, kickback and over-heating of the motor. Should the cut begin to go off the line, DO NOT try to force it back. Release the switch and allow blade to come to a complete stop, then withdraw the saw, realign, and start a new cut slightly inside the wrong one. In any event, withdraw the saw if you must shift the cut. Forcing a correction inside the cut can stall the saw and lead to kickback. IF SAW STALLS, RELEASE THE TRIGGER, ALLOW THE BLADE TO COME TO A COMPLETE STOP, AND BACK THE SAW UNTIL IT IS LOOSE. BE SURE BLADE IS STRAIGHT IN THE CUT AND CLEAR OF THE CUTTING EDGE BEFORE RESTARTING. As you finish a cut, release the trigger and allow the blade to stop before lifting the saw from the work. As you lift the saw, the springtensioned guard will automatically close around the blade. Remember the blade is exposed until this occurs, never reach under the work for any reason whatsoever.

Always use a track, fence or straight edge guide when ripping. NOTE: When cutting thin strips, be careful to ensure that the narrow strips do not feed up into the inside of the blade enclosure. NOTE: The tracks, available in different lengths, allow for precise, clean cuts and simultaneously protect the workpiece surface against damage.

PLUNGE CUTS (FIG. 1, 9)

WARNING: ALWAYS use the track when plunge cutting. WARNING: To avoid kickbacks, the following instructions MUST

be observed when plunge cutting:

1. Place the machine

FIG. 9

onto the track and release the antikickback knob (U) by turning it counterclockwise.

2. Turn the machine on and slowly press the saw down onto the set cutting depth and push forward in the cutting direction. The cut indicators (T) display the absolute front and the absolute rear cutting points of the saw blade [dia. 6-1/2" (165 mm)] at maximum cutting depth and using the track.

3. If kickback happened during the plunge cut, turn the antikickback knob (U) counterclockwise to release it from the track.

English

4. When you have finished the plunge cut, turn the anti-kickback knob (U) clockwise into the lock position.

CROSS-CUTTING

Cutting directly across the grain of a piece of lumber is called crosscutting. Figures 10 and 11 illustrate a crosscut operation. Position the work so that the cut will be on the left.

FIG. 10 FIG. 11

RIPPING

Ripping is cutting wood lengthwise. This operation is performed in the same manner as crosscutting with the exception of supporting the workpiece. If the workpiece is supported on a large table, bench, or floor, several pieces of scrap stock approximately 1" (25.4 mm) thick should be placed beneath the material to allow clearance for the portion of the saw blade that extends thru the workpiece. Large sheets of paneling or thin plywood supported on saw horses should have 2 x 4’s placed lengthwise between the horses and the workpiece to prevent it from sagging in the center.

BEVEL CUTTING

Make your bevel cuts in the same manner as crosscuts and rip cuts, but set the blade at an angle between 0° and 47°.

The bevel cut made at an angle to the edge of a board is called a compound cut.

KICKBACK

When the saw blade becomes pinched or twisted in the cut, kickback can occur. The saw is thrust rapidly back 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 backward. When 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 more likely to occur when any of the following conditions exist.

1. IMPROPER WORKPIECE SUPPORT

A. Sagging or improper lifting of the cut off piece can cause

pinching of the blade and lead to kickback.

B. Cutting through material supported at the outer ends only

can cause kickback. As the material weakens it sags, closing down the kerf and pinching the blade.

C. Cutting off a cantilevered or overhanging piece of material

from the bottom up in a vertical direction can cause kickback. The falling cut off piece can pinch the blade.

D. Cutting off long narrow strips (as in ripping) can cause

kickback. The cut off strip can sag or twist closing the kerf and pinching the blade.

E. Snagging the lower guard on a surface below the material

being cut momentarily reduces operator control. The saw can lift partially out of the cut increasing the chance of blade twist.

2. IMPROPER DEPTH OF CUT SETTING ON SAW

To make the most efficient cut, the blade should protrude only

far enough to expose 1/2 of a tooth. This allows the shoe to

English

support the blade and minimizes twisting and pinching in the material. See the section titled Cutting Depth Adjustment.

3. BLADE TWISTING (MISALIGNMENT IN CUT)

A. Pushing harder to cut through a knot, a nail, or a hard grain

area can cause the blade to twist.

B. Trying to turn the saw in the cut (trying to get back on the

marked line) can cause blade twist.

C. Over-reaching or operating the saw with poor body control

(out of balance), can result in twisting the blade.

D. Changing hand grip or body position while cutting can result

in blade twist.

E. Backing up the saw to clear blade can lead to twist.

4 MATERIALS THAT REQUIRE EXTRA ATTENTION

A. Wet lumber B. Green lumber (material freshly cut or not kiln dried) C. Pressure treated lumber (material treated with preservatives

or anti-rot chemicals)

5. USE OF DULL OR DIRTY BLADES

Dull blades cause increased loading of the saw. To compensate,

an operator will usually push harder which further loads the unit and promotes twisting of the blade in the kerf. Worn blades may also have insufficient body clearance which increases the chance of binding and increased loading.

6. LIFTING THE SAW WHEN MAKING BEVEL CUT

Bevel cuts require special operator attention to proper cutting

techniques - especially guidance of the saw. Both blade angle to the shoe and greater blade surface in the material increase the chance for binding and misalignment (twist) to occur.

7. RESTARTING A CUT WITH THE BLADE TEETH JAMMED AGAINST THE MATERIAL

The saw should be brought up to full operating speed before

starting a cut or restarting a cut after the unit has been stopped with the blade in the kerf. Failure to do so can cause stalling and kickback.

Any other conditions which could result in pinching, binding, twisting, or misalignment of the blade could cause kickback. Refer to the sections on Adjustments and Set-Up and Operation for procedures and techniques that will minimize the occurrence of kickback.

Blades

WARNING: To minimize the risk of eye injury, always wear

ANSI Z87.1 approved 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: NEVER cut ferrous metals (those with any iron or

steel content), masonry, glass or tile with this saw. Damage to the saw and personal injury may result.

A dull blade will cause inefficient cutting, overload on the saw motor, excessive splintering and increase the possibility of kickback. Change blades when it is no longer easy to push the saw through the cut, when the motor is straining, or when excessive heat is built up in the blade. It is a good practice to keep extra blades on hand so that sharp blades are available for immediate use. Dull blades can be sharpened in most areas; see SAWS-SHARPENING in the yellow pages. Hardened gum on the blade can be removed with kerosene, turpentine, or oven cleaner. Anti-stick coated blades can be used in applications where excessive build-up is encountered, such as pressure treated and green lumber.

English

BLADE SELECTION

Your DEWALT track saw is designed for use with 6-1/2" (165 mm) diameter blades that have a 0.79" (20 mm) diameter bore. Blades must be rated for 6000 RPM operation (or higher).

DO NOT use any

abrasive wheels.

A combination blade is furnished with your saw and is an excellent blade for all general ripping and crosscutting operations. Use a finetooth blade for cutting plywood.

WARNING: VISUALLY EXAMINE CARBIDE BLADES BEFORE

USE. REPLACE IF DAMAGED.

Track Saw System (Fig. 1)

The tracks, which are available in different lengths, allow for precise, clean cuts and simultaneously protect the workpiece surface against damage. In conjunction with additional accessories, exact angled cuts, miter cuts and ﬁtting work can be completed with the track saw system. Securing the workpiece with clamps ensures a secure hold and safe working. The guide clearance of the track saw must be very small for best cutting results and can be set with the two track adjusters (J).

1. Release the screw inside the track adjuster to adjust the clearance.

2. Adjust the knob until saw locks on track.

3. Rotate knob back until saw slides easily.

4. Hold the track adjuster in position and lock the screw again.

NOTE: ALWAYS readjust the system for use with other tracks.

Anti-splinter Strip

The track is equipped with a anti-splinter strip, which has to be cut to size before the ﬁrst use:

IMPORTANT: ALWAYS read and follow the track saw system instruction before cutting the anti-splinter strip!

1. Set the speed of the track saw to level 5.

2. Place the track on a scrap piece of wood.

3. Set the track saw on 3/16" (5 mm) cut depth.

4. Place the saw on the rear end of the track.

5. Turn the saw on, press it down to the set cutting depth and cut the anti-splinter strip along the full length in one contiuous operation. The edge of the anti-splinter strip now corresponds exactly to the cutting edge of the blade.

WARNING: To reduce the risk of injury, ALWAYS secure the

track (W) with a clamp.

Wall Cutting (Fig. 1, 12)

1. Place the track saw with the outer guard (V) on a clean, flat floor.

2. Press the shoe (D) with the front side on the wall against the adjusted depth stop.

NOTE: The minimum cut between wall and workpiece is

12 mm.
