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 mains‑operated (corded) power tool or battery‑operated (cordless) power tool.

Work Area Safety

• Keep work area clean and well-lit. Cluttered or dark areas invite accidents.
• 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.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety

• 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.

• 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.

• Do not expose power tools to rain or wet
  conditions. Water entering a power tool will increase the risk of electric shock.

• 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.

• 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.

• 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.

Personal Safety

• 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.

• 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 energizing power tools that have the switch on invites accidents.
• 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.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
• 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.
• 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.

Power Tool Use and Care

• 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.

• 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.

• 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.

• 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.

• 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.

• Keep cutting tools sharp and clean. Properly
  maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

• 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.

• 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.

Battery Tool Use and Care

• 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.

• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

• 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.
  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.

• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.

• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265 °F (130 °C) may cause explosion.

DRILL/IMPACT DRILL SAFETY WARNINGS

1. Safety Instructions for All Operations

   • Wear ear protectors when impact drilling.
     Exposure to noise can cause hearing loss.

   • Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory or fasteners may contact hidden wiring. Cutting accessory or fastener contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

2. Safety Instructions When Using Long Drill Bits

   • Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
   • b ) Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
   • Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend causing breakage or loss of control, resulting in personal injury.

Additional Safety Warnings for Drills

• Do not operate this tool for long periods of time. Vibration caused by the operating action of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide extra cushion, take frequent rest periods, and limit daily time of use.
• Hammer bits and tools get hot during operation. Wear gloves when touching them.

Additional Safety Information

WARNING:

• Never modify the power tool or any part of it. Damage or personal injury could result.
• 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.
• Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
  • lead from lead‑based paints,
  • crystalline silica from bricks and cement and other masonry products, and
  • arsenic and chromium from chemically‑treated lumber.

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.

• 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. Direct particles away from face and body.
• Use the appropriate dust extractor vacuum to remove the vast majority of static and airborne dust. Failure to remove static and airborne dust could contaminate the working environment or pose an increased health risk to the operator and those in close proximity.
• Use clamps or other practical ways 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 and injury.
• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long hair can be caught in moving parts.

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 knocked over.

4. Keep the motor running when pulling the bit back out of a drilled hole to prevent jamming.

Recommendations for Drilling

• When drilling, always apply pressure in a straight line with the bit, but do not push hard enough to stall the motor or deflect the bit.

IF THE DRILL STALLS :

• RELEASE TRIGG ER SWITCH IMMEDIATELY, remove drill bit from work, and determine cause of stalling.
• DO NOT DEPRESS TRIGG ER SWITCH ON AND OFF IN AN ATTEMPT TO START A STALL ED DRILL —THIS CAN DAMAGE THE DRILL .
• To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole.
• Large holes (5/16″ to 1/2″ [7.9 mm to 12.7 mm]) in steel can be made more easily if a pilot hole (5/32″ to 3/16″ [4 mm to 4.8 mm]) is drilled first.
• If drilling thin material or material that is prone to splinter, use a wood “back‑up” block to prevent damage to the workpiece.

Hammerdrilling DCD798

IMPORTANT: Use carbide‑tipped or masonry bits rated for percussion drilling only.

1. Select the desired speed/torque range using the speed selector 7 to match the speed and torque to the planned operation. Turn the mode selection collar 6 to the hammerdrill symbol.
2. Pull the trigger, applying just enough pressure on the hammer to keep it from bouncing excessively or “rising” off the bit.

Recommendations for Hammerdrilling

• Too much force will cause slower drilling speeds, overheating, and a lower drilling rate.
• A smooth even flow of material indicates the proper drilling rate.
• Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit when drillling as this will cause clogging of the bit flutes and a slower drilling speed.
• When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the hole with tool still running to help clear debris from the hole.
