Safety Instructions

General Power Tool Safety Warnings
WARNING
Read all safety warnings and all 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.
Work area safety

• Keep the 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 that may ignite 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 the 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 the 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. The 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.
  The 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 masks, non-skid safety shoes, hard hats, 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 a 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.
  The 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 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.

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.
  The use of any other battery packs may create a risk of injury and fire.

• When the 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 the eyes, additionally seek medical help.
  Liquid ejected from the battery may cause irritation or burns.

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.

Safety Warnings for Angle Grinder

Safety Warnings common for Grinding or Abrasive Cutting Off operations

• This power tool is intended to function as a grinder or cut-off tool. 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.

• Operations such as sanding, wire brushing, or polishing are not recommended to be performed with this power tool.
  Operations for which the power tool was not designed may create a hazard and cause personal injury.

• Do not use accessories that are not specifically designed and recommended by the tool manufacturer.
  Just because the accessory can be attached to your power tool, it does not assure safe operation.

• The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart.

• The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool.
  Incorrectly sized accessories cannot be adequately guarded or controlled.

• The threaded mounting of accessories must match the grinder spindle thread. For accessories mounted by flanges, the arbor hole of the accessory must fit the locating diameter of the flange. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively, and may cause a loss of control.

• Do not use a damaged accessory. Before each use inspects the accessory such as abrasive wheels for chips and cracks, a backing pad for cracks, tears, or excess wear, and a wire brush for loose or cracked wires. If a power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute.
  Damaged accessories will normally break apart during this test time.

• Wear personal protective equipment. Depending on the application, use a face shield, safety goggles, or safety glasses. As appropriate, wear a dust mask, hearing protectors, gloves, and a workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high-intensity noise may cause hearing loss.

• Keep bystanders a safe distance away from the work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpieces or of a broken accessory may fly away and cause injury beyond the immediate area of operation.

• Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.

• Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.

• Regularly clean the power tool’s air vents. The motor’s fan will draw dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.

• Do not operate the power tool near flammable materials. Sparks could ignite these materials.

• Do not use accessories that require liquid coolants.
  Using water or other liquid coolants may result in electrocution or shock.

Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush, or any other accessory.
Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on the direction of the wheel’s movement at the point of inching. Abrasive wheels may also break under these conditions. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

• Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use an auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces if proper precautions are taken.

• Never place your hand near the rotating accessory. The accessory may kick back over your hand.

• Do not position your body in the area where the power tool will move if kickback occurs. Kickback will propel the tool in a direction opposite to the wheel’s movement at the point of snagging.

• Use special care when working corners, sharp edges, etc. Avoid bouncing and snagging the accessory.
  Corners, sharp edges, or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback.

• Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickbacks and loss of control.

Safety Warnings Specific for Grinding and Abrasive Cutting-Off operations

• Use only wheel types that are recommended for your power tool and the specific guard designed for the selected wheel.
  Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe.

• The grinding surface of center-depressed wheels must be mounted below the plane of the guard lip. An improperly mounted wheel that projects through the plane
  of the guard lip cannot be adequately protected.

• The guard must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed to the operator.
  The guard helps to protect the operator from broken wheel fragments, accidental contact with the wheel, and sparks that could ignite clothing.

• Wheels must be used only for recommended applications. For example: do not grind with the side of the cutoff wheel.
  Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.

• Always use undamaged wheel flanges that are of the correct size and shape for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel flanges.

• Do not use worn-down wheels from larger power tools. Wheel intended for larger power tools is not suitable for the higher speed of a smaller tool and may burst.

Additional Safety Warnings Specific for Abrasive Cutting-Off operations

• Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.

• Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of operation, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directly at you.

• When the wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur.
  Investigate and take corrective action to eliminate the cause of wheel binding.

• Do not restart the cutting operation in the workpiece.
  Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up or kick back if the power tool is restarted in the workpiece.

• Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight.
  Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.

• Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring, or objects that can cause kickback.

Additional safety information Wear safety goggles.

• Use suitable detectors to determine if there are hidden supply lines or contact the local utility company for assistance. Contact with electric cables can cause fire and electric shock. Damaging gas lines can lead to explosions. Breaking water pipes causes property damage.

• Do not touch grinding and cutting discs until they have cooled down. The discs can become very hot while working.

• Release the On/Off switch and set it to the Off position when the power supply is interrupted, e.g. when the battery pack is removed. This prevents uncontrolled
  restarting.

• In case of damage and improper use of the battery, vapors may be emitted.
  The battery can set alight or explode.
  Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The vapors may irritate the respiratory system.

• Do not open the battery. There is a risk of short-circuiting.

• The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur, causing the battery to burn, smoke, explode or overheat.

• Only use the battery with products from the manufacturer. This is the only way in which you can protect the battery against dangerous overload.
  Protect the battery against heat, e.g. against continuous intense sunlight, fire, dirt, water, and moisture. There is a risk of explosion and short- circuiting.

• Do not touch grinding discs until they have cooled down. The discs can become very hot while working.

• Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more securely than by hand.

Noise/Vibration Information

Noise emission values were determined according to EN   60745-2-3.
Typically, the A-weighted sound pressure level of the power tool is 75 dB(A). Uncertainty K = 3 dB. The noise level when working can exceed the volume stated. Wear hearing protection! Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745-2-3:
Surface grinding (roughing): ah = 13.5 m/s², K = 1.5 m/s²,
The vibration level given in these instructions has been measured in accordance with a standardized measuring procedure and may be used to compare power tools. It can also be used for a preliminary estimation of exposure to vibration.
The stated vibration level applies to the main applications of the power tool. However, if the power tool is used for different applications, with different application tools, or poorly maintain ned, the vibration level may differ. This can significantly increase the exposure to vibration over the total working period.
To estimate the exposure to vibration accurately, the times when the tool is switched off or when it is running but not actually being used should also be taken into account. This
can significantly reduce the exposure to vibration over the total working period.
Implement additional safety measures to protect the operator from the effects of vibration, such as servicing the power tool and application tools, keeping the hands warm, and organizing workflows correctly.

  Temperature monitoring/overload protection indicator
  The red LED indicator (6) helps you to protect the battery against overheating and the motor against overload.
  If the LED indicator (6) is lit up permanently in red, the temperature of the battery is too high and the power tool switches off automatically.
  – Switch the power tool off.
  – Allow the battery to cool down before you carry on working.
  If the LED indicator (6) is flashing red, then the power tool is blocked and will switch off automatically.
  Pull the power tool out of the workpiece.
  The power tool will continue to work as soon as the blockage is rectified.

Practical advice

• Exercise caution when cutting slots in structural walls; see the “Information on structural design” section.
• When cutting lightweight materials, take into account the statutory provisions and recommendations of the material manufacturer.
• Clamp the workpiece if it is not secure under its own weight.
• Do not load the power tool so heavily that it comes to a stop.
• If the power tool has been subjected to a heavy load, continue to run it at no-load for several minutes to cool down the accessory.
• Do not use the power tool with a cut-off stand.
• Do not touch grinding and cutting discs until they have cooled down. The discs can become very hot while working.

If the power tool becomes electrostatically charged, the built-in electronics will switch the power tool off. Press the on/off switch (3) again to restart the power tool.
Rough grinding

• Never use cutting discs for rough grinding.
  The best rough grinding results are achieved with a set angle of 30° to 40°. Move the power tool back and forth with moderate pressure. This will ensure that the workpiece does not become too hot or discolored and that grooves are not formed.

Cutting metal

• Always use the protective guard for cutting (10) when cutting bonded abrasives.
  When carrying out abrasive cutting, use a moderate feed that is suited to the material being machined. Do not exert pressure on the cutting disc and do not tilt or swing the
  power tool.
  Do not attempt to reduce the speed of a cutting disc coming to a stop by applying pressure from the side.
  The power tool must always work in an up-grinding motion.
  Otherwise, there is a risk that it will be pushed uncontrolled out of the cut.
  For best results when cutting profiles and rectangular tubing, start at the smallest cross-section.

Cutting Stone

• Provide sufficient dust extraction when cutting stone.
• Wear a dust mask.
• The power tool may be used only for dry cutting/grinding.
  For cutting stone, it is best to use a diamond cutting disc.
  When cutting especially hard materials such as concrete with a high pebble content, the diamond cutting disc can overheat and become damaged as a result. This is clearly indicated by circular sparking, rotating with the diamond cutting disc.
  If this happens, stop cutting and allow the diamond cutting disc to cool down by running the power tool for a short time at maximum speed with no load.
  If work is noticeably slower and circular sparking is present, this indicates that the diamond cutting disc has become blunt. You can resharpen the disc by briefly cutting it into abrasive material (e.g. lime-sand brick).

Information on structural design
Slots in load-bearing walls are subject to DIN 1053 part 1 or country-specific regulations. These regulations must be observed under all circumstances. Seek advice from the responsible structural engineer, architect, or construction supervisor before starting work.
Recommendations for optimal handling of the battery Protect the battery against moisture and water.
Only store the battery only within a temperature range of -20 to 50 °C. Do not leave the battery in your car in the summer, for example.
Occasionally clean the ventilation slots on the battery using a soft brush that is clean and dry.
A significantly reduced operating time after charging indicates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.

Maintenance and Service

Maintenance and Cleaning

• Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is a risk of injury from unintentionally pressing the on/off switch.
