Safety Instructions

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 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 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 a 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 energising 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 and clothing 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.
  • 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.

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 instructions for reciprocating saws

  • Hold the 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 another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by hand or against your body leaves it unstable and may lead to loss of control.
  • Keep hands away from the sawing area. Do not reach under the workpiece. Contact with the saw blade can lead to injuries.
  • Hold the power tool firmly with both hands and make sure you have a stable footing. The power tool can be more securely guided with both hands.
  • Only bring the power tool into contact with the workpiece when switched on. Otherwise there is danger of kickback if the cutting tool jams in the workpiece.
  • Ensure that the footplate is always resting on the workpiece while sawing. The saw blade can jam and lead to loss of control over the power tool.
  • When the cut is completed, switch off the power tool and then pull the saw blade out of the cut only after it has come to a standstill. In this manner you can avoid kickback and can place down the power tool securely.
  • Always wait until the power tool has come to a complete stop before placing it down. The application tool can jam and cause you to lose control of the power tool.
  • Use only undamaged saw blades that are in perfect condition. Bent or dull saw blades can break, negatively influence the cut, or lead to kickback.
  • Do not brake the saw blade to a stop by applying side pressure after switching off. The saw blade can be damaged, break or cause kickback.
  • Ensure that the material is securely clamped. Do not support the workpiece using your hands or feet. Do not touch any objects or the floor with the saw while it is running. There is a risk of kickback.
  • Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to an explosion. Penetrating a water line causes property damage or may cause an electric shock.

Noise/Vibration Information
Noise emission values determined according to EN 60745-2-3. Typically the A-weighted noise level of the power tool are: 83 dB(A); sound power level 94 dB(A). Uncertainty K = 3 dB.
Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745-2-3: Surface grinding (roughing): ah = 5.5 m/s2, K = 1.5 m/s2,Disc sanding:ah < 2.5 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 maintained, 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 organising workflows correctly.

Kickback control
If there is a sudden kickback in the power tool, e.g. jamming in a separating cut, the power supply to the motor will be interrupted electronically. To restart the tool, set the On/Off switch (8) to the “off” position and then switch the power tool on again.

Run-out brake
The power tool is fitted with the electronic Bosch Brake System. When it is switched off, the abrasive tool is brought to a complete stop within a few seconds. This means that the runout time is significantly shorter than for angle grinders without a run-out brake and enables the power tool to be set down sooner.
Soft start
The electronic soft start limits the torque when the power tool is switched on and enables a smooth start-up.
Note: If the power tool runs at full speed immediately after being switched on, this means that the soft start and restart protection mechanisms have failed. The power tool must be sent to the after-sales service immediately; see the “AfterSales Service and Application Service” section for addresses.
Restart protection
The restart protection feature prevents the power tool from uncontrolled starting after the power supply to it has been interrupted. To restart the tool, set the on/off switch (8) to the off position and then switch the power tool on again.
Impact shutdown
The integrated impact shutdown switches the power tool off as soon as it hits the floor. To restart the tool, set the on/off switch (8) to the “off” position and then switch the power tool on again.

Rechargeable battery
Bosch sells some cordless power tools without a rechargeable battery. You can tell whether a rechargeable battery is included with the power tool by looking at the packaging.
Charging the battery

  • Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your power tool.

Note: Lithium-ion rechargeable batteries are supplied partially charged according to international transport regulations. To ensure full rechargeable battery capacity, fully charge the rechargeable battery before using your tool for the first time.
Inserting the Battery
Push the charged battery into the battery holder until it clicks into place.

Removing the Battery
To remove the rechargeable battery, press the battery release button and pull the battery out. Do not use force to do this. The rechargeable battery has two locking levels to prevent the battery from falling out if the battery release button is pressed unintentionally. The rechargeable battery is held in place by a spring when fitted in the power tool.
Battery charge indicator
The green LEDs on the battery charge indicator indicate the state of charge of the battery. For safety reasons, it is only possible to check the state of charge when the power tool is not in operation. Press the button for the battery charge indicator or to show the state of charge. This is also possible when the battery is removed. If no LED lights up after pressing the button for the battery charge indicator, then the battery is defective and must be replaced.

GCY 42 Read the corresponding operating instructions for information about the Bluetooth® Low Energy Module GCY 42.

Fitting Protective Equipment

  • 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 risk of injury from unintentionally pressing the on/off switch.

Note: If the grinding disc breaks during operation or the holding fixtures on the protective guard/power tool become damaged, the power tool must be sent to the after-sales service immediately; see the “After-Sales Service and Application Service” section for addresses.

Protective guard for grinding

Place the protective guard (10) onto the holder on the power tool until the coding cams of the protective guard are aligned with the holder. When doing so, press and hold the unlocking lever (1). Press the protective guard (10) onto the spindle collar until the shoulder of the protective guard is sitting on the flange of the power tool and rotate the protective guard until it audibly clicks into place. Adjust the position of the protective guard (10) to meet the requirements of the operation. To do this, push the unlocking lever (1) upward and rotate the protective guard (10) into the required position.

  • Always position the protective guard (10) such that the two cams on the unlocking lever (1) engage in the corresponding openings on the protective guard (10).
  • Adjust the protective guard (10) such that sparking in the direction of the operator is prevented.
  • The protective guard (10) must only be adjustable while the unlocking lever (1) is actuated. Otherwise, the power tool must not be used any more under any circumstances and must be sent to the after-sales service.

Note: The coding cams on the protective guard (10) ensure that only a protective guard that is suitable for the power tool can be fitted.

Protective guard for cutting

  • When cutting, always use the protective guard for grinding (10) with a fitted cover for cutting (11).
  • Provide sufficient dust extraction when cutting stone.

Cover for cutting
Fit the cover for cutting (11) on the protective guard for grinding (10) (see figure A): Swivel the lever back (➊). Attach the cover (11) to the protective guard for grinding (10) (➋). Press the lever firmly into place again on the protective guard (10) (➌). To remove the cover (see figure B), swivel the lever back (➊). Remove the cover (11) from the protective guard (10) (➋).

Handguard

  • Always fit the hand guard (17) when working with the rubber sanding pad (18) or with the cup brush/conical brush.

Attach the hand guard (17) to the auxiliary handle (7).
Low-vibration auxiliary handle
Note: The GWS 18V-180 PC angle grinder is supplied with a low-vibration auxiliary handle (7) that extends the distance between the user and the gearbox housing. Always use the low-vibration auxiliary handle (7) described in this operating manual to ensure operational safety and optimum ergonomics. The low-vibration auxiliary handle (7) reduces vibration, enabling the tool to be used safely and more comfortably. Screw the auxiliary handle (7) on the right or left of the machine head depending on the working method.

  • Do not operate your power tool without the auxiliary handle (7).
  • Do not continue to use the power tool if the auxiliary handle (7) is damaged. Do not make any alterations to the auxiliary handle (7).

Fitting the Abrasive Tools

  • 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 risk of injury from unintentionally pressing the on/off switch.

  • Do not touch grinding and cutting discs until they have cooled down. The discs can become very hot while working.
    Clean the grinding spindle (16) and all the parts to be fitted. Lock the grinding spindle with the spindle lock button (3) before clamping and releasing the abrasive tools.

  • Do not press the spindle lock button while the grinding spindle is moving. The power tool may become damaged if you do this.

Grinding/cutting disc
Pay attention to the dimensions of the abrasive tools. The diameter of the hole must match that of the mounting flange. Do not use an adapter or reducer.
When using diamond cutting discs, make sure that the direction of rotation arrow on the diamond cutting disc corresponds to the direction of rotation of the machine (see direction of rotation arrow on the housing). See the graphics page for fitting instructions. Note: When assembling bonded grinding or cutting discs using the supplied mounting flange (12) and the clamping nut (15), the use of intermediate layers is not necessary. To secure the grinding/cutting disc, place the mounting flange with O-ring (12) on the grinding spindle (16) and screw on the clamping nut (15). Ensure the alignment of the clamping nut (15) depending on the grinding/cutting disc used (see figures in the front part of the operating manual), and tighten them with the two-pin spanner.

  • After fitting the abrasive tool, check that the abrasive tool is fitted correctly and can turn freely before switching on the power tool. Make sure that the abrasive tool does not brush against the protective guard or other parts.

A plastic part (O-ring) is fitted around the centring collar in the mounting flange (12). If the O-ring is missing or damaged, the mounting flange (12) must be replaced before operation can resume.

Approved abrasive tools
You can use all the abrasive tools mentioned in these operating instructions. The permissible speed [min-1] or the circumferential speed [m/s] of the abrasive tools used must at least match the values given in the table. It is therefore important to observe the permissible rotational/circumferential speed on the label of the abrasive tool.

Rotating the machine head (see figure C)

  • 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 risk of injury from unintentionally pressing the on/off switch.

The machine head can be rotated in 90° increments. In this way, the on/off switch can be brought into a more favourable handling position for particular applications, e.g. for lefthanded tool users. Completely unscrew the four screws (➊). Rotate the machine head carefully, without removing it from the housing, into the new position (➋). Screw in and retighten the four screws (➌).

Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s health. Touching or breathing-in the dust can cause allergic reactions and/or lead to respiratory infections of the user or bystanders. Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.

  • Provide for good ventilation of the working place.
  • It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the materials to be worked.

  • Avoid dust accumulation at the workplace. Dust can easily ignite.

Operation

  • Do not load the power tool so heavily that it comes to a
    stop.

  • 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 risk of injury from unintentionally pressing the on/off switch.

  • Exercise caution when cutting slots in structural walls; see the “Information on structural design” section.

  • Clamp the workpiece if it is not secure under its own weight.

  • 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.

Working advice
Rough grinding

  • Always use the protective guard for grinding (10) when rough grinding with bonded abrasives.
  • Never use cutting discs for rough grinding.
  • When rough grinding, the protective guard for grinding (10) with a fitted cover for cutting (11) can impact the workpiece and lead to a loss of control.

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 discolour and that grooves are not formed.

  • The protective guard for grinding (10) must be used with a fitted cover for cutting (11) when using bonded discs which are approved for cutting and grinding.

Surface grinding with flap disc

  • Always use the protective guard for grinding (10) when grinding with the flap disc.

The flap disc (accessory) enables you to machine curved surfaces and profiles. Flap discs have a considerably longer service life, lower noise levels and lower grinding temperatures than conventional grinding discs.

Surface grinding with sanding disc

  • Always fit the hand guard (17) when working with the rubber sanding pad (18).

Grinding with a sanding disc can be done without a protective guard. See the graphics page for fitting instructions. Screw on the round nut (21) and tighten it with the two-pin spanner.

Cup brush/disc brush/conical brush

  • Always use the protective guard for grinding (10) when brushing with disc brushes. Brushing with cup brushes/conical brushes can be performed without the protective guard.
  • Always fit the hand guard (17) when working with the cup brush or conical brush.
  • The wires of the disc brush can get caught on the protective guard and break, if the maximum permitted dimensions of the disc brushes are exceeded.

See the graphics page for fitting instructions. The cup brush/conical brush/disc brush with M14 thread must be screwed onto the grinding spindle until it rests firmly against the grinding spindle flange at the end of the grinding spindle thread. Tighten the cup brush/conical brush/disc brush with an open-ended spanner. To fasten the disc brush with a diameter of 22.22 mm, attach the mounting flange with O-ring (12) to the grinding spindle (16), screw on the round nut (21) and tighten with the two-pin spanner.

Cutting Metal

  • For cutting metal with bonded cutting discs or diamond cutting discs, always use the protective guard for grinding (10) with a fitted cover for cutting (11).
  • When using the protective guard for grinding (10) for cutting work with bonded cutting discs, there is an increased risk of being exposed to sparks, particles and disc fragments if the disc breaks.

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

  • For cutting stone with bonded cutting discs or diamond cutting discs for stone/concrete, always use the protective guard for grinding (10) with a fitted cover for cutting (11).
  • Provide sufficient dust extraction when cutting stone.
  • Wear a dust mask.
  • The power tool may be used only for dry cutting/grinding.
  • When using the protective guard for grinding (10) or the protective guard for grinding (10) with a fitted cover for cutting (11) for cutting and grinding applications in concrete or masonry, there is an increased dust load and an increased risk of losing control of the power tool, which can lead to kickback.

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 canoverheat 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 with circular sparking, this indicates that the diamond cutting disc has become blunt. You can resharpen the disc by briefly cutting into abrasive material (e.g. lime-sand brick).

Cutting other materials

  • For cutting materials such as plastics, composite materials, etc. with bonded cutting discs or Carbide Multi Wheel cutting discs, always use the protective guard for grinding (10) with a fitted cover for cutting (11).

Information on structural design

Transport
The recommended lithium-ion batteries are subject to legislation on the transport of dangerous goods. The user can transport the batteries by road without further requirements. When shipping by third parties (e.g.: by air transport or forwarding agency), special requirements on packaging and labelling must be observed. For preparation of the item being shipped, consulting an expert for hazardous material is required. Dispatch battery packs only when the housing is undamaged. Tape or mask off open contacts and pack up the battery in such a manner that it cannot move around in the packaging. Please also observe the possibility of more detailed national regulations.
