USER MANUAL DCS578 DEWALT

the following address or refer to the back of themanual. The undersigned is responsible for compilation of the technical file and makes this declaration on behalf of DeWALT

The vibration and/or noise emission level given in this information sheet has been measured in accordance with a standardised test given in EN62841 and may be used to compare one tool with another. It may be used for a preliminary assessment ofexposure.

WARNING: The declared vibration and/or noise emission

level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration and/or noise emission may differ. This may significantly increase the exposure level over the total workingperiod. An estimation of the level of exposure to vibration and/ or noise should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total workingperiod. Identify additional safety measures to protect the operator from the effects of vibration and/or noise such as: maintain the tool and the accessories, keep the hands warm (relevant for vibration), organisation of workpatterns.

WARNING: Read all safety warnings, instructions,

illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or seriousinjury.

SAVE ALL WARNINGS AND INSTRUCTIONS

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

a ) Keep work area clean and well lit. Cluttered or dark areas inviteaccidents. 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 orfumes. c ) Keep children and bystanders away while operating a power tool. Distractions can cause you to losecontrol.

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 electricshock. 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 orgrounded. c ) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electricshock. 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 electricshock. 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 electricshock. f ) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electricshock.

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 personalinjury. b ) Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personalinjuries. 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 invitesaccidents. 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 personalinjury. e ) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpectedsituations. f ) Dress properly. Do not wear loose clothing or jewellery.

Loose clothes, jewellery or long hair can be caught in movingparts. 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-relatedhazards. h ) Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of asecond.

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 wasdesigned. 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 berepaired. c ) Disconnect the plug from the power source and/ or remove the battery pack, if detachable, 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 toolaccidentally. 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 untrainedusers. e ) Maintain power tools and accessories. 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 powertools. f ) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier tocontrol. 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 hazardoussituation. h ) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpectedsituations.

5) Battery Tool Use and Care

a ) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another batterypack. b ) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury andfire. 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 afire. 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 orburns. e ) Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk ofinjury. f ) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C may causeexplosion. g ) Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

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 ismaintained. b ) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized serviceproviders. Safety Instructions for All Saws Cutting Procedures a ) 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 theblade. b ) Do not reach underneath the workpiece. The guard cannot protect you from the blade below theworkpiece. c ) Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below theworkpiece. d ) Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the work properly to minimize body exposure, blade binding, or loss ofcontrol. e ) Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting tool may contact hidden wiring. Contact with a "live" wire will also make exposed metal parts of the power tool "live" and could give the operator an electricshock. f ) When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of bladebinding. 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 off-centre, causing loss ofcontrol.46 EnGLISH 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 ofoperation. Further Safety Instructions for All Saws Kickback Causes and Related Warnings

• 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 theoperator. 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 firm 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 aretaken. 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 bladebinding. c ) When restarting a saw in the workpiece, centre the saw blade in the kerf and check that saw teeth are not engaged into the material. If saw blade binds, it may walk up or kickback from the workpiece as the saw isrestarted. d ) Support large panels to minimise 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 thepanel. e ) Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding andkickback. f ) Blade depth and bevel adjusting locking levers must be tight and secure before making the cut. If blade adjustment shifts while cutting, it may cause binding andkickback. g ) Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can causekickback. Safety Instructions for Saws with a Pendulum Blade Guard a ) Check the 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 the 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 ofcut. 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 build-up ofdebris. c ) The lower guard may be retracted manually only for special cuts such as “plunge cuts” and “compound cuts”. Raise the lower guard by the retracting handle and as soon as the blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operateautomatically. d ) Always observe that the lower 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 isreleased. Additional Safety Instructions for CircularSaws

• Wear ear protectors. Exposure to noise can cause hearingloss.

• Wear a dust mask. Exposure to dust particles can cause breathing difficulty and possibleinjury.

• Do not use blades of larger or smaller diameter than recommended. For the proper blade rating refer to the technical data. Use only the blades specified in this manual, complying with EN847-1.

• Use only saw blades that are marked with a speed equal or higher than the speed marked on thetool.

• Avoid overheating of bladetips.

• Install the dust extraction port onto the saw beforeuse.

• Never use abrasive cut-offwheels.

• Do not use water feedattachments.

• 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 ofcontrol. Residual Risks In spite of the application of the relevant safety regulations and the implementation of safety devices, certain residual risks cannot be avoided. These are:

• Impairment ofhearing.47 EnGLISH

• Risk of personal injury due to flyingparticles.

• Risk of burns due to accessories becoming hot duringoperation.

• Risk of personal injury due to prolongeduse.

1. Plug the charger into an appropriate outlet before inserting

into the charger, making sure the battery pack is fully seated in the charger. The red (charging) light will blink repeatedly indicating that the charging process hasstarted.

3. The completion of charge will be indicated by the red light

remaining ON continuously. The battery pack is fully charged and may be used at this time or left in the charger. To remove the battery pack from the charger, push the battery release button

on the batterypack. NOTE: To ensure maximum performance and life of lithium-ion battery packs, charge the battery pack fully before firstuse. Charger Operation Refer to the indicators below for the charge status of the batterypack. Charge Indicators Charging Fully Charged Hot/Cold Pack Delay*

• The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack has reached an appropriate temperature, the yellow light will turn off and the charger will resume the chargingprocedure. The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery by refusing tolight. NOTE: This could also mean a problem with acharger. If the charger indicates a problem, take the charger and battery pack to be tested at an authorised servicecentre. Hot/Cold Pack Delay When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery packlife. A cold battery pack will charge at a slower rate than a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery packwarms. The DCB118 charger is equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled. Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit foreign objects to enter the interior of thecharger. Electronic Protection System XR Li-Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deepdischarge. The tool will automatically turn off if the Electronic Protection System engages. If this occurs, place the lithium-ion battery pack on the charger until it is fullycharged. Wall Mounting These chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede air flow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 25.4mm long with a screw head diameter of 7–9mm, screwed into wood to an optimal depth leaving approximately 5.5mm of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in theslots. Charger Cleaning Instructions

WARNING: Shock hazard. Disconnect the charger

from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. Do not use water or any cleaning solutions. Never let any liquid get inside the tool; never immerse any part of the tool into aliquid.

battery pack so that metal objects can contact exposed battery terminals. For example, do not place the battery pack in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys,etc.

CAUTION: When not in use, place tool on its side on a stable surface where it will not cause a tripping or falling hazard. Some tools with large battery packs will stand upright on the battery pack but may be easily knockedover. Transportation

WARNING: Fire hazard. Transporting batteries can

possibly cause fire if the battery terminals inadvertently come in contact with conductive materials. When transporting batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a shortcircuit. NOTE: Lithium-ion batteries should not be put in checkedbaggage. DeWALT batteries comply with all applicable shipping regulations as prescribed by industry and legal standards which include UN Recommendations on the Transport of Dangerous Goods; International Air Transport Association (IATA) Dangerous Goods Regulations, International Maritime Dangerous Goods (IMDG) Regulations, and the European Agreement Concerning The International Carriage of Dangerous Goods by Road (ADR). Lithium-ion cells and batteries have been tested to section 38.3 of the UN Recommendations on the Transport of Dangerous Goods Manual of Tests andCriteria. In most instances, shipping a DeWALT battery pack will be excepted from being classified as a fully regulated Class 9 Hazardous Material. In general, only shipments containing a lithium-ion battery with an energy rating greater than 100 Watt Hours (Wh) will require being shipped as fully regulated Class 9. All lithium-ion batteries have the Watt Hour rating marked on the pack. Furthermore, due to regulation complexities, DeWALT

does not recommend air shipping lithium-ion battery packs alone regardless of Watt Hour rating. Shipments of tools with batteries (combo kits) can be air shipped as excepted if the Watt Hour rating of the battery pack is no greater than 100Whr. Regardless of whether a shipment is considered excepted or fully regulated, it is the shipper's responsibility to consult the latest regulations for packaging, labeling/marking and documentationrequirements. The information provided in this section of the manual is provided in good faith and believed to be accurate at the time the document was created. However, no warranty, expressed or implied, is given. It is the buyer’s responsibility to ensure that its activities comply with the applicableregulations. Transporting the FLEXVOLT

Battery The DeWALT FLEXVOLT

battery has two modes: Use andTransport. Use Mode: When the FLEXVOLT

battery stands alone or is in

DeWALT 18V product, it will operate as an 18V battery. When the FLEXVOLT

battery is in a 54V or a 108V (two 54V batteries) product, it will operate as a 54Vbattery. Transport Mode: When the cap is attached to the FLEXVOLT

battery, the battery is in Transport mode. Keep the cap for shipping. When in Transport mode, strings of cells are electrically disconnected within the pack resulting in 3 batteries with a lower Watt hour (Wh) rating as compared to 1 battery with a higher Watt hour rating. This increased quantity of 3 batteries with the lower Watt hour rating can exempt the pack from certain shipping regulations that are imposed upon the higher Watt hour batteries. For example, the Transport Wh rating might indicate 3x36 Wh, meaning 3 batteries of 36 Wh each. The Use Wh rating might indicate 108Wh (1battery implied). Storage Recommendations

1. The best storage place is one that is cool and dry away

from direct sunlight and excess heat or cold. For optimum battery performance and life, store battery packs at room temperature when not inuse.

2. For long storage, it is recommended to store a fully charged

battery pack in a cool, dry place out of the charger for optimalresults. NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will need to be recharged beforeuse. Labels on Charger and Battery Pack In addition to the pictographs used in this manual, the labels on the charger and the battery pack may show the followingpictographs: Read instruction manual beforeuse.

6. Follow steps 1 through 5 under To Install the Blade, making

sure that the blade will rotate in the properdirection. Lower Blade Guard

WARNING: The lower blade guard is a safety feature

that reduces the risk of serious personal injury. Never use the saw if the lower guard is missing, damaged, misassembled 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 the lower blade guard for proper closing before each use. If the lower blade guard is missing or not working properly, have the saw serviced before using. To assure product safety and reliability, repair, maintenance and adjustment should be performed by an authorised service centre or other qualified service organization, always using identical replacementparts. Checking the Lower Guard (Fig.A)

1. Turn tool off and disconnect from powersupply.

2. Rotate the lower guard lever

from the fully closed position to the fully openposition.

3. Release the lever and observe the guard

return to the fully closedposition. The tool should be serviced by a qualified service centre if it:

• fails to return to the fully closed position,

• moves intermittently or slowly, or

• contacts the blade or any part of the tool in all angles and depth ofcut. Blades

WARNING: To minimise the risk of eye injury, always

use eye protection. Carbide is a hard but brittle material. Foreign objects in the workpiece 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, sharpblade.

WARNING: Do not cut metal, plastic, concrete, masonry

or fiber cement materials with thissaw. 190mm Diameter Application Teeth Fast rip 18 Rip 24 General Purpose 40 184mm Diameter Application Teeth Rip 24 General Purpose 36 Finish 60 If you need assistance regarding blades, please contact your local DeWALT dealer. 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 material causing the blade to climb out of the kerf and jump back toward theoperator. Kickback is more likely to occur when any of the following conditionsexists.

1. IMPROPER WORKPIECE SUPPORT FIG. X

a. Sagging or improper lifting of the cut off piece can cause pinching of the blade and lead to kickback (Fig.X). 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 (Fig.X). 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 theblade. d. Cutting off long narrow strips can cause kickback. The cut off strip can sag or twist closing the kerf and pinching theblade. 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 bladetwist.

2. IMPROPER DEPTH OF CUT SETTING ON SAW FIG. H

To make the most efficient cut, the blade should protrude only far enough to expose a tooth as shown in FigureH. This allows the shoe to support the blade and minimises twisting and pinching in the material. See the section titled Depth of CutAdjustment.

3. BLADE TWISTING MISALIGNMENT IN CUT

a. Pushing harder to cut can cause the blade totwist. b. Trying to turn the saw in the cut (trying to get back on the marked line) can cause bladetwist. c. Overreaching or operating the saw with poor body control (out of balance), can result in twisting theblade. d. Changing hand grip or body position while cutting can result in bladetwist. e. Backing up the saw to clear blade can lead totwist.

4. 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 increasedloading.

The saw should be brought up to full operating speed before starting a cut or restarting a cut after the unit has53 ENGLISH been stopped with the blade in the kerf. Failure to do so can cause stalling andkickback. Any other conditions which could result in pinching, binding, twisting, or misalignment of the blade could cause kickback. Refer to the sections Further Safety Instructions for All Saws and Blades for procedures and techniques that will minimise the occurrence ofkickback. Depth of Cut Adjustment (Fig.F–H)

saw blade, set the depth adjustment so that about one half of a tooth projects below the surface of the wood to becut.

5. A method of checking for the correct cutting depth is

shown in Fig.H. Lay a piece of the material you plan to cut along the side of the blade, as shown in the Figure, and observe how much tooth projects beyond thematerial. Adjusting Depth Adjustment Lever (Fig.G) It may be desirable to adjust the depth adjustment lever

Bevel Angle Adjustment (Fig.A,I) The bevel angle adjustment mechanism

can be adjusted between 0° and 57°. To achieve better accuracy in cutting, use the fine adjustment markings located on the pivot bracket

2. Tilt the base plate to the desired angle by aligning the fine

with the desired angle mark on the pivot bracket

Bevel Detent (Fig.I) The DCS578 and DCS579 are equipped with a bevel detent feature. As you tilt the base plate you will hear a click and feel the base plate stop at both 22.5 and 45 degrees. If either of these is the desired angle, retighten the lever

by lowering it. If you desire another angle, continue tilting the base plate until the coarse bevel pointer

aligns with the desiredmark. Cut Length Indicator (Fig.J) The markings on the side of the base plate

show the length of the slot being cut into the material at the full depth of the cut. The markings are in increments of 5mm. Mounting and Adjusting the Parallel Fence (Fig.K) The parallel fence

5. Insert screws and tightensecurely.

Guide Rail System (Fig.M) DCS579 Guide rails, available in different lengths as accessories, allow the use of the circular saw for precise, straight clean cuts and simultaneously protect the workpiece surface against damage. In conjunction with additional accessories, exact angled cuts, mitre cuts and fitting work can be completed with the guide railsystem. Clamps

are available to secure the guide rail

(Fig.M). Use of these clamps

ensure that the guide rail

is securely attached to the workpiece

for safe working. Once the guide rail is set to the cut line and securely fixed to the workpiece, there is no movement duringcutting. IMPORTANT: The height scale on the unit is set for using the saw without a guide rail. When using the saw on the guide rail the difference in height will be approximately 5.0mm. Setting the Circular Saw To the Guide Rail(Fig.A,N) The clearance between the circular saw and the guide rail (Fig.N,

) must be very small to achieve best cutting results. The smaller this clearance the better the straight line finish will be on theworkpiece.54 EnGLISH The clearance can be set with the two rail adjusters

(Fig.A) for each channel in the base for 0° cutting

and for 1–45° bevel cutting

. The rail adjusters are precision cams that allow for the reduction of clearance between the unit and guide rail. Once these adjusters have been set, sideways movement of the saw during cutting is kept to a minimum while allowing a smooth cuttingaction. nOTE: The adjusters are set to minimum clearance in the factory and may need adjusting and setting before the unit is used. Use the following instructions for setting the circular saw to the guiderail. REMEMBER: Set the rail adjusters on the saw to the guiderail.

1. Undo the screw inside the rail adjuster to allow for

adjustment between the saw and the guiderail.

2. Retract the lower guard and place the unit on the guide rail,

ensuring the blade is in the highestposition.

3. Rotate the adjuster until saw locks on guiderail.

IMPORTanT: Make sure the saw is securely attached to the rail by trying to push the saw forward. Ensure there is no movement of thesaw.

4. Rotate the adjuster back slightly until saw slides easily along

5. Hold the rail adjuster in position and tighten the

screwagain. nOTE: aLWaYS adjust the system for use with otherrails. The rail adjusters are now set up to minimise sideways deviation when cutting with the saw on the guiderail. Before using the saw, the anti-splinter guard

on the guide rail will need tuning in. Refer to Tuning the Anti-SplinterGuard. Tuning the Anti-Splinter Guard (Fig.N) The guide rail

is equipped with an anti-splinter guard

that has to be tuned to the saw before the firstuse. The anti-splinter guard

is situated on each edge of the guide rail (Fig.N). The purpose of this anti-splinter guard is to provide the user with a visible blade cut line while reducing the chipping that occurs along the workpiece cut edge duringcutting. IMPORTanT: aLWaYS read and follow the Setting the Circular Saw to the Guide Rail before cutting the splinterguard! Steps to Tune the Anti-Splinter Guard (Fig.O–R)

on a scrap piece of wood

with a minimum length of 100mm overhanging the workpiece (Fig. O). Use a clamp to ensure that the guide rail is securely attached to the workpiece. This will ensureaccuracy.

2. Set the unit to a 20mm depth ofcut.

3. Place the front of the saw on the overhang end of the guide

rail, making sure that the blade is positioned in front of the rail edge (Fig.P).

4. Turn the saw on and slowly cut the splinter guard along the

full length of the rail in one continuous operation. The edge of the splinter guard now corresponds exactly to the cutting edge of the blade (Fig.Q). To tune in the anti-splinter guard on the other side of the guide rail, remove the saw from the rail and rotate the rail 180°. Repeat steps 1 through4. nOTE: If desired, the splinter guard can be bevelled to 45°, then repeat steps 1 through 4. This allows one side of the rail for cutting parallel cuts and the other side of the rail is tuned in for 45° bevel cuts (Fig.R). nOTE: If the anti-splinter guard is tuned in for parallel cutting on both sides, then when the unit is bevelled, the blade will not run true to the edge of the anti-splinter guard. This is because the pivot point of the unit bevel is not stationary and the blade moves out over when the unit isbevelled. Kerf Indicator (Fig.S–U) The front of the saw shoe has a kerf indicator

for vertical and bevel cutting. This indicator enables you to guide the saw along cutting lines penciled on the material being cut. The kerf indicator lines up with the left (outer) side of the saw blade, which makes the slot or “kerf” cut by the moving blade fall to the right of the indicator. Guide along the penciled cutting line so that the kerf falls into the waste or surplus material. Fig.T shows the saw in the parallel cutting position relative to the guide rail. Fig.U shows the saw in the bevel cutting position relative to the guiderail. Prior to Operation

• Make sure the guards have been mounted correctly. The saw blade guard must be in closedposition.

• Make sure the saw blade rotates in the direction of the arrow on theblade.

• Do not use excessively worn sawblades. OPERATION Instructions for Use

When the trigger is released, the worklight will stay illuminated for up to 20seconds.55 EnGLISH nOTE: The worklight is for lighting the immediate work surface and is not intended to be used as aflashlight. Switching On and Off (Fig.A) For safety reasons the trigger switch

of your tool is equipped with a lock-off button

Press the lock-off button to unlock thetool. To run the tool, press the trigger switch

. As soon as the trigger switch is released, the lock-off switch is automatically activated to prevent unintended starting of themachine. NOTICE: Do not switch the tool ON or OFF when the saw blade touches the workpiece or othermaterials. Workpiece Support (Fig.W–Z)

WARNING: To reduce the risk of serious personal

injury, support the work properly and hold the saw firmly to prevent loss ofcontrol. Fig. W and Y show proper sawing position. Fig. X and Z show an unsafe condition. Hands should be kept away fromcutting. To avoid kickback, ALWAYS support board or panel NEAR the cut, (Fig. W and Y). DON’T support board or panel away from the cut (Fig.X,Z). ALWAYS DISCONNECT BATTERY PACK BEFORE MAKING ANY ADJUSTMENTS! 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 sawit. Cutting (Fig.Y)

WARNING: Never attempt to use this tool by resting it

upside down on a work surface and bringing the material to the tool. Always securely clamp the workpiece and bring the tool to the workpiece, securely holding the tool with two hands as shown in Fig.Y. Place the wider portion of the saw base plate on that part of the work piece which is solidly supported, not on the section that will fall off when the cut is made. As examples, Fig.Y illustrates the RIGHT way to cut off the end of a board. Always clamp work. Don’t try to hold short pieces by hand! Remember to support cantilevered and overhanging material. Use caution when sawing material frombelow. Be sure saw is up to full speed before blade contacts material to be cut. Starting saw with blade against material to be cut or pushed forward into kerf can result in kickback. 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 working without much decrease in speed. Forcing the saw can cause rough cuts, inaccuracy, kickback, and over-heating of the motor. Should your cut begin to go off the line, don’t try to force it back on. Release the switch and allow blade to come to a complete stop. Then you can withdraw the saw, sight anew, 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 tokickback. IF SAW STALLS, RELEASE THE TRIGGER AND BACK THE SAW UNTIL IT IS LOOSE. BE SURE BLADE IS STRAIGHT IN THE CUT AND CLEAR OF THE CUTTING EDGE BEFORERESTARTING. 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 spring-tensioned telescoping guard will automatically close under the blade. Remember the blade is exposed until this occurs. Never reach under the work for any reason. When you have to retract the telescoping guard manually (as is necessary for starting pocket cuts) always use the retractinglever. nOTE: When cutting thin strips, be careful to ensure that small cutoff pieces don’t hang up on inside of lowerguard. Pocket Cutting (Fig.AA)

WARNING: Never tie the blade guard in a raised position.

Never move the saw backwards when pocket cutting. This may cause the unit to raise up off the work surface which could causeinjury. A pocket cut is one that is made in a floor, wall or other flatsurface.

1. Adjust the saw base plate so the blade cuts at desireddepth.

2. Tilt the saw forward and rest front of the base plate on

3. Using the lower guard lever, retract lower blade guard to an

upward position. Lower rear of base plate until blade teeth almost touch cuttingline.

4. Release the blade guard (its contact with the work will keep

it in position to open freely as you start the cut). Remove hand from guard lever and firmly grip auxiliary handle

, as shown in Fig.AA. Position your body and arm to allow you to resist kickback if itoccurs.

5. Make sure blade is not in contact with cutting surface before

6. Start the motor and gradually lower the saw until its base

plate rests flat on the material to be cut. Advance saw along the cutting line until cut iscompleted.

7. Release trigger and allow blade to stop completely before

withdrawing the blade from thematerial.

8. When starting each new cut, repeat asabove.

Dust Extraction (Fig.DD)

WARNING: Risk of dust inhalation. To reduce the risk of

personal injury, ALWAYS wear an approved dustmask. A dust extraction port

is supplied with yourtool. The dust extraction port allows you to connect the tool to an external dust extractor, either using the AirLock™ system (DWV9000-XJ), or a standard 35mm dust extractorfitment.

WARNING: ALWAYS use a vacuum extractor designed

in compliance with the applicable directives regarding dust emission when sawing wood. Vacuum hoses of most common vacuum cleaners will fit directly into the dust extractionoutlet.56 ENGLISH Rafter Hook (Fig.A) (Included with some models)

WARNING: To reduce the risk of serious personal injury,

do not use the tool's rafter hook to hang the tool from your body. DO NOT use the rafter hook for tethering or securing the tool to a person or object during use. DO NOT suspend tool overhead or suspend objects from the rafterhook.

WARNING: To reduce the risk of injury from the circular

saw falling on operators or bystanders, make sure it is supported securely when using the rafter hook, or resting in a secure and stable location when not in use. Be sure to keep the area below clear to reduce the risk of the tool or off-cut material falling and striking someone or somethingbelow. The circular saw has a convenient rafter hook

that allows it to hang on a suitable, stable structure between uses. The rafter hook is not for tethering or securing the tool to a person or object during use whenelevated. MAINTENANCE Your DeWALT power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regularcleaning.

WARNING: To reduce the risk of serious personal

injury, turn tool off and disconnect battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start-up can causeinjury. The charger and battery pack are notserviceable. Lubrication Self lubricating ball and roller bearings are used in the tool and relubrication is not required. However, it is recommended that, once a year, you take or send the tool to a service centre for a thorough cleaning, inspection and lubrication of the gearcase. Cleaning

WARNING: Blow dirt and dust out of the main housing

with dry air as often as dirt is seen collecting in and around the air vents. Wear approved eye protection and approved dust mask when performing thisprocedure.

WARNING: Never use solvents or other harsh chemicals

for cleaning the non-metallic parts of the tool. These chemicals may weaken the materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into aliquid. Lower Guard The lower guard should always rotate and close freely from a fully open to fully closed position. Always check for correct operation before cutting by fully opening the guard and letting it close. If the guard closes slowly or not completely, it will need cleaning or servicing. Do not use the saw until it functions correctly. To clean the guard, use dry air or a soft brush to remove all accumulated sawdust or debris from the path of the guard and from around the guard spring. Should this not correct the problem, it will need to be serviced by an authorised servicecentre. Base Plate Adjustment (Fig.E,BB,CC) Your base plate has been factory set to assure that the blade is perpendicular to the base plate. If after extended use you need to re-align the blade, follow the directions below: Adjusting for 90 Degree Cuts

Blades 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 mostareas. 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 greenlumber.57 EnGLISH Optional Accessories
