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 residual current device (RCD) protected supply. Use of an RCD 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.
  • 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.
  • 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 jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery 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.

• 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  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.
  • 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. 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.

• Service

  • Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Additional Safety Instructions for Rotary Hammers

• Wear ear protectors. Exposure to noise can cause hearing loss.
• Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
• Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• 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 safety goggles or other eye protection. Hammering operations cause chips to fly. Flying particles can cause permanent eye damage. Wear a dust mask or respirator for applications that generate dust. Ear protection may be required for most applications.
• Keep a firm grip on the tool at all times. Do not attempt to operate this tool without holding it with both hands. It is recommended that the side handle be used at all times. Operating this tool with one hand will result in loss of control. Breaking through or encountering hard materials such as re-bar may be hazardous as well. Tighten the side handle securely before use.
• Do not operate this tool for long periods of time. Vibration caused by hammer action may be harmful to your hands and arms. Use gloves to provide extra cushion and limit exposure by taking frequent rest periods.
• Do not recondition bits yourself. Chisel reconditioning should be done by an authorized specialist. Improperly reconditioned chisels could cause injury.
• Wear gloves when operating tool or changing bits. Accessible metal parts on the tool and bits may get extremely hot during operation. Small bits of broken material may damage bare hands.
• Never lay the tool down until the bit has come to a complete stop. Moving bits could cause injury.
• Do not strike jammed bits with a hammer to dislodge them. Fragments of metal or material chips could dislodge and cause injury.
• Slightly worn chisels can be rehappened by grinding.
• Keep the power cord away from the rotating bit. Do not wrap the cord around any part of your body. An electric cord wrapped around a spinning bit may cause personal injury and loss of control.
  WARNING: We recommend the use of a residual current device with a residual current rating of 30mA or less.

Residual Risks
The following risks are inherent to the use of rotary hammers:

• Injuries caused by touching the rotating parts or hot parts of the tool.

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.
• Risk of burns due to accessories becoming hot during operation.
• Risk of personal injury due to prolonged use.

Electrical Safety
The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the voltage on the rating plate.
Your DEWALT tool is double insulated in accordance with EN60745; therefore no earth wire is required.
WARNING: 115 V units have to be operated via a fail-safe isolating transformer with an earth screen between the primary and secondary winding.
If the supply cord is damaged, it must be replaced by a specially prepared cord available through the DEWALT service organisation.

Mains Plug Replacement (U.K. & Ireland Only)

If a new mains plug needs to be fitted:

• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal.
• WARNING: No connection is to be made to the earth terminal.
  Follow the fitting instructions supplied with good quality plugs. Recommended fuse: 13 A.

Using an Extension Cable
An extension cord should not be used unless absolutely necessary. Use an approved extension cable suitable for the power input of your tool (see Technical Data). The minimum conductor size is 1.5 mm2; the maximum length is 30 m. When using a cable reel, always unwind the cable completely.

Intended Use

Your rotary hammerdrill has been designed for professional drilling and hammerdrilling applications, as well as screwdriving and chipping applications.
DO NOT use under wet conditions or in the presence of flammable liquids or gases. Your rotary hammerdrill is a professional power tool.
DO NOT let children come into contact with the tool. Supervision is required when inexperienced operators use this tool.

• Young children and the infirm. This appliance is not intended for use by young children or infirm persons without supervision.
• This product is not intended for use by persons (including children) suffering from diminished physical, sensory or mental abilities; lack of experience, knowledge or skills unless they are supervised by a person responsible for their safety. Children should never be left alone with this product.

Overload Clutch
In case of jamming of a drill bit, the drive to the drill spindle is interrupted. Because of the resulting forces, always hold the tool with both hands and take a firm stance. After the overload, release and depress the trigger to re-engage drive.

Mechanical Clutch
These tools are fitted with a mechanical clutch. The indication that the clutch has activated will be an audible ratcheting together with increased vibration.

Active Vibration Control
For best vibration control, hold the tool as described in Proper Hand Position.
The active vibration control neutralises rebound vibration from the hammer mechanism. Lowering hand and arm vibration, it allows more comfortable use for longer periods of time and extends the life of the unit.
The hammer only needs enough pressure to engage the active vibraton control. Applying too much pressure will not make the tool drill or chip faster and active vibration control will not engage.
