m/s² ≤ 2.5 Uncertainty K = m/s² 1.5 The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.

WARNING: The declared vibration

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 emission may differ. This may significantly increase the exposure level over the total working period. An estimation of the level of exposure to vibration 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 working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

WARNING: To reduce the risk of injury,

read the instruction manual. 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.

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.ENGLISH

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, 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, 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 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.

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.ENGLISH

Drill/Driver/Hammerdrill Safety Warnings

• Wear ear protectors with impact drills. Exposure to noise can cause hearing loss.

• Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the tool “live” and shock the operator.

• Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.

• Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.

• Wear ear protectors when hammering for extended periods of time. Prolonged exposure to high intensity noise can cause hearing loss. Temporary hearing loss or serious ear drum damage may result from high sound levels generated by hammerdrilling.

• Wear safety goggles or other eye protection. Hammering and drilling operations cause chips to fly. Flying particles can cause permanent eye damage.

• Hammer bits and tools get hot during operation. Wear gloves when touching them. Labels on Tool

Variable Speed Trigger Switch (fi g. 1) To turn the tool on, squeeze the trigger switch (a). To turn the tool off, release the trigger switch.ENGLISH

Your tool is equipped with a brake. The chuck will stop as soon as the trigger switch is fully released. NOTE: Continuous use in variable speed range is not recommended. It may damage the switch and should be avoided. Forward/Reverse Control Button (fi g. 1) A forward/reverse control button (b) determines the direction of the tool and also serves as a lock-off button. To select forward rotation, release the trigger switch and depress the forward/reverse control button on the right side of the tool. To select reverse, depress the forward/reverse control button on the left side of the tool. The center position of the control button locks the tool in the OFF position. When changing the position of the control button, be sure the trigger is released. NOTE: The first time the tool is run after changing the direction of rotation, you may hear a click on start up. This is normal and does not indicate a problem. Mode Control Collar Your drill is equipped with a separate mode control collar (fig. 1, c) to switch between drilling, screwdriving and hammerdrilling mode. SCREWDRIVING (FIG. 4)

1. Select the desired speed/torque range using the

three-speed gear shifter (e) on the top of tool to match the speed and torque to the planned application. To set the torque level to the proper setting on the clutch collar, initially set the clutch collar at a lower setting to ensure the fastener to be set to your specification. NOTE: Use the lowest torque setting required to seat the fastener at the desired depth. The lower the number, the lower the torque output.

2. Rotate the mode control collar (c) so the screw

symbol is aligned with the arrow.

3. Set the torque adjustment collar (d) to the

appropriate number setting for the torque desired. NOTE: The torque adjustment collar may be set on any number and change between screwdriving and drilling modes using the mode control collar. DRILLING (FIG. 5) CAUTION: When the mode collar is in the drill/hammerdrill mode, the drill will not clutch out regardless of the position of the torque adjustment collar (d). Rotate the mode control collar (c) so the drill symbol is aligned with the arrow. NOTE: The torque adjustment collar (d) may be set on any number. HAMMERDRILLING (FIG. 6) Rotate the mode control collar (c) so the hammer symbol is aligned with the arrow. Torque Adjustment Collar (fi g. 4) Your tool has an adjustable torque screwdriver mechanism for driving and removing a wide array of fastener shapes and sizes and a hammer mechanism for drilling into masonry. Circling the torque adjustment collar (d) are numbers. These numbers are used to set the clutch to deliver a torque range. The higher the number on the collar, the higher the torque and the larger the fastener which can be driven. To select any of the numbers, rotate until the desired number aligns with the arrow. Three-Speed Gearing (fi g. 4) The three-speed feature of your tool allows you to shift gears for greater versatility. To select speed 1 (highest torque setting), turn the tool off and permit it to stop. Slide the gear shifter (e) all the way to the left. Speed 2 (middle torque and speed setting) is in the middle position. Speed 3 (highest speed setting) is to the right. NOTE: Do not change gears when the tool is running. Always allow the drill to come to a complete stop before changing gears. If you have trouble changing gears, make sure that the gear shifter is engaged in one of the three speed settings. Self-Tightening Chuck Operation (fi g. 7–9)

WARNING: Do not attempt to tighten

drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may result. Always lock off trigger switch when changing acces sories.

WARNING: Always ensure the bit

is secure before starting the tool. A loose bit may eject from tool causing possible personal injury. TO INSERT A DRILL BIT OR OTHER ACCESSORY

1. Lock the trigger in the OFF position.ENGLISH

2. Grasp the chuck sleeve (f) with one hand and

use the other hand to secure the tool as shown in figure 7. Rotate the sleeve counterclockwise (viewed from the front) far enough to accept the desired accessory.

3. Insert the bit or other accessory about 19 mm

(3/4") into the chuck, as shown in figure 8. Grasp the chuck sleeve securely and rotate the sleeve clockwise (viewed from the front) with one hand while using the other hand to secure the tool. Rotate the sleeve clockwise until sleeve cannot be rotated any further, as demonstrated in figure 9. As the drill is being operated in the forward position, the chuck will continually self-tighten the jaws of the chuck onto the bit to maximize the bit gripping strength. To release the accessory, repeat Step 2. Drill Operation

1. Select the desired speed/torque range using the

gear shifter to match the speed and torque to the planned operation.

2. For WOOD, use twist bits, spade bits, power

auger bits or hole saws. For METAL, use high- speed steel twist drill bits or hole saws. Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should be drilled dry.

3. Always apply pressure in a straight line with the

bit. Use enough pressure to keep the drill bit biting, but do not push hard enough to stall the motor or deflect the bit.

4. Hold tool firmly with both hands to control the

twisting action of the drill.

5. IF DRILL STALLS, it is usually because it

is being overloaded. RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL – THIS CAN DAMAGE THE DRILL.

6. Keep the motor running when pulling the bit

back out of a drilled hole. This will help prevent jamming. Hammerdrill Operation

1. When drilling, use just enough force on the

hammer to keep it from bouncing excessively or “rising” off the bit. Too much force will cause slower drilling speeds, overheating, and a lower drilling rate.

2. Drill straight, keeping the bit at a right angle to

the work. Do not exert side pressure on the bit when drilling as this will cause clogging of the bit flutes and a slower drilling speed.

3. When drilling deep holes, if the hammer speed

starts to drop off, pull the bit partially out of the hole with the tool still running to help clear debris from the hole.

4. For MASONRY, use carbide-tipped bits or

masonry bits. A smooth, even flow of dust indicates the proper drilling rate. Screwdriver Operation Select the desired speed/torque range using the three-speed gear shift lever on the top of tool to match the speed and torque to the planned operation. Insert the desired fastener accessory into the chuck as you would any drill bit. Set the torque adjustment collar (d) to the desired setting. Make a few practice runs in scrap or unseen areas to determine the proper position of the clutch collar. 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 regular cleaning.

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 cause injury.
