GENERAL POWER TOOL SAFETY WARNINGS

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 serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS

FOR FUTURE REFERENCE.

The term “power tool” in the warnings refers to your mainsoperated (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.

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 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 a dust mask, non-skid 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 and clothing 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.

English 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 a second.

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 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 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 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 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.

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 unexpected situations.

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 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

8 contacts eyes, additionally seek medical help.

Liquid ejected from the battery may cause irritation or burns.

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 of injury.

f ) Do not expose a battery pack or tool to fire or excessive temperature.

Exposure to fire or temperature above 130 °C may cause explosion.

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.

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.

b ) Never service damaged battery packs.

Service of battery packs should only be performed by the manufacturer or authorized service providers.

Additional Specific Safety Rules

Safety Instructions for All Saws

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 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 workpiece 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. 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 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 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, 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 is restarted.

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 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.

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

English 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 base plate of the saw will not shift while performing the “plunge cut.” 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 saw blade for the riving knife.

For the riving knife to function, the body of the blade must be thinner than the riving knife and the cutting width of the blade must be wider than the thickness of the riving knife.

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.

c ) For the riving knife to work, it must be engaged in the workpiece.

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

d ) 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 Plunge-

Type 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.

• 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 EN 847-1.

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

• Never use abrasive cut-off wheels .

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 of hearing.

• Risk of personal injury due to flying particles.

English

• Risk of burns due to accessories becoming hot during operation.

• Risk of personal injury due to prolonged use.

When transporting batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit.

NOTE: Lithium-ion batteries should not be put in checked baggage.

D e WALT 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 and Criteria.

In most instances, shipping a D e WALT 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, D e

WALT 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 100 Whr.

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 documentation requirements.

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 applicable regulations.

Transporting the FlEXVOlT TM Battery

The D e WALT FLEXVOLT and Transport .

TM battery has two modes: Use

Use Mode: When the FLEXVOLT TM battery stands alone or is in a D e WALT 18V product, it will operate as an 18V battery. When the FLEXVOLT TM battery is in a 54V or a 108V (two 54V batteries) product, it will operate as a 54V battery.

Transport Mode: When the cap is attached to the FLEXVOLT TM 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 3 x 36 Wh, meaning 3 batteries of

Example of Use and Transport Label Marking

36 Wh each. The Use Wh rating might indicate 108 Wh (1 battery 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 in use.

2. For long storage, it is recommended to store a fully charged battery pack in a cool, dry place out of the charger for optimal results.

nOTE: Battery packs should not be stored completely depleted of charge. The battery pack will need to be recharged before use.

English

Plunge Cuts

WARNING: To avoid kickbacks, the following instructions

MUST be observed when plunge cutting:

• Place the machine onto the guide rail and release the anti-kickback knob 18 by turning it counterclockwise.

• Turn the machine on and slowly press the saw down onto the set cutting depth and push forward in the cutting direction. The cutting indicators 27 display the absolute front and the absolute rear cutting points of the saw blade (dia. 165 mm) at maximum cutting depth and using the guide rail.

• If kickback happened during the plunge cut, turn the anti-kickback knob 18 counterclockwise to release it from the rail.

• When you have finished the plunge cut, turn the antikickback knob 18 clockwise into the lock position.

Guide Rail System (Fig. A, F)

The guide rails 28 , 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, mitre cuts and ﬁtting work can be completed with the guide rail system.

Securing the workpiece with clamps ensures a secure hold and safe working.

The guide clearance of the plunge saw must be very small for best cutting results and can be set with the two rail adjustment knobs 5 .

1. Release the screw inside the rail adjustment knobs 5 to adjust the clearance.

2. Adjust the knob until saw locks on rail.

3. Rotate knob back until saw slides easily.

4. Hold the rail adjustment knob in position and lock the screw again.

nOTE: AlWAYs readjust the system for use with other rails.

Anti-Splinter Guard (Fig. G, H)

The guide rail 28 is equipped with an anti-splinter guard 30 , which has to be trimmed before the ﬁrst use.

The anti-splinter guard 30 is situated on each edge of the guide rail ( 28 , Fig. G). 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 during cutting.

iMPORTAnT: AlWAYs read and follow the Guide Rail System instructions before cutting the splinterguard!

1. Set the speed of the plunge saw to level 7.

2. Place the guide rail 28 on a scrap piece of wood. Use a clamp to ensure that the guide rail is securely attached to the workpiece. This will ensure accuracy.

3. Set the plunge saw on 5 mm cut depth.

4. Place the saw on the rear end of the guide rail.

5. Turn the saw on, press it down to the set cutting depth and cut the anti-splinter guard 30 along the full length in one

English continuous operation. The edge of the anti-splinter guard now corresponds exactly to the cutting edge of the blade.

To trim 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 through 4. 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. H). nOTE: If the anti-splinter guard is trimmed 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 when the unit is bevelled.

WARNING: To reduce the risk of injury, ALWAYS secure the guide rail with a clamp.

Speed Adjustment (Fig. A)

The speed can be regulated between 2500 and 4200 rpm using the speed wheel 19 . This enables you to optimise the cutting speed to suit the material. Refer to the following chart for type of material and speed range.

Type of Material to be Cut

Solid wood (hard, soft)

Chipboards

Laminated wood, blockboards, veneered and coated boards

Speed Range

3–7

4–7

Paper and carton 1–3

Door Cutting (Fig. I)

1. Place the plunge saw with the outer guard 23 on a clean, flat floor.

2. Press the shoe 4 with the front side on the door against the adjusted depth stop.

Dust Extraction (Fig. A)

WARNING: Risk of dust inhalation. To reduce the risk of personal injury, ALWAYS wear an approved dust mask.

Your tool is fitted with a dust extraction outlet 17 .

The Dust Extraction Adaptor allows you to connect the tool to an external dust extractor, either using the AirLock™ system

(DWV9000-XJ), or a standard 35 mm dust extractor fitment.

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 extraction outlet.
