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 cord away from heat, oil, sharp edges, and 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 at 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.

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 Diamond Drills
General Information for Diamond Drills

• 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 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.
• Store the machine in a safe manner when not being used. The storage location must be dry and lockable. This prevents the machine from storage damage, and from being operated by untrained persons.
• Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.
• Never use the machine with a damaged cable. Do not touch the damaged cable and pull the mains plug when the cable is damaged while working. Damaged cables increase the risk of an electric shock.
• Check the cable regularly and have a damaged cable repaired only through an authorized customer service agent for Bosch power tools. Replace damaged extension cables. This will ensure that the safety of the power tool is maintained.
• Wear non-skid shoes. This prevents injuries that can occur from slipping on smooth surfaces.
• Use only original Bosch accessories.
• The safety and operating instructions for the drill stand and the accessories being used are to be strictly observed!
• Connect the machine to a mains supply with a proper earthing connection. The socket-outlet and extension cable must be equipped with an operative protective conductor.
• The power tool may only be operated on the main supply with a protective conductor and adequate dimensioning.

Safety Warnings for Working without Drill Stand

• Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
• When working with the machine, always hold it firmly with both hands and provide a secure stance. The power tool is guided more securely with both hands.
• Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool.
• If the application tool should become blocked, switch the machine off. Loosen the application tool.
• Before switching on the power tool, make sure that the application tool moves freely. When switching on with a blocked drilling tool, a high torque reaction can occur. Safety Warnings for Working with Drill Stand
• Never leave the machine before it has come to a complete stop. Cutting tools that are still running can cause injuries. Safety Warnings for Wet Drilling
• Never operate the machine without the portable residual current device (PRCD) provided. Products sold in GB only: Never operate the 110 V execution of the machine without an isolation transformer according to EN/IEC 61558-1 and EN/IEC 61558-2-23. The isolation transformer must have a grounded earth wire on the secondary winding side.
• Before starting work, check the proper function of the portable residual current device (PRCD). Have a damaged portable residual current device (PRCD) repaired or replaced by your Bosch after-sales service agent.
• Pay attention that neither persons in the working area nor the power tool itself come into contact with the water that comes out.

When wet drilling overhead, the escaping water must be collected.
To do this, insert the power tool into a drill stand and mount a water collecting ring (see “Accessories/Spare Parts”, page 15).

• Ensure that water-carrying hoses, connectors, and the water collection ring (accessory) are in immaculate condition. Replace damaged or worn parts before the next use. Water escaping from parts of the power tool will increase the risk of electric shock.

Technical Data

Noise/Vibration Information
Sound emission values were determined according to EN 60745-2-1.
Typically the A-weighted noise levels of the product are Sound pressure level 88 dB(A); Sound power level 99 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745-2-1: Drilling into concrete: ah =4.8m/s 2 2 , K=1.5 m/s .
The vibration level given in this information sheet has been measured in accordance with a standardized 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. 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 insertion tools or is 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: maintaining the tool and the accessories, keeping the hands warm, and organization of work patterns.

Assembly

• Before any work on the machine itself, pull the mains plug.

Operation without Drill Stand

• Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury. Always attach the auxiliary handle 12 when operating without a drill stand. To do so, slide the auxiliary handle over the drill spindle 15 onto the spindle collar (see illustration on the graphics page).
  Tighten the wing bolt for adjustment of the auxiliary handle 16 in a clockwise direction. The auxiliary handle 12 can be set to any position for a secure and low-fatigue working posture.
  Turn the wing bolt for adjustment of the auxiliary handle 16 in an anticlockwise direction and set the auxiliary handle 12 to the required position. Then tighten the wing bolt 16 again in a clockwise direction.
• Before any work, make sure that the wing bolt 16 is firmly tightened. Loss of control can cause personal injury.

Operation with Drill Stand

• The safety and operating instructions for the drill stand being used are to be strictly observed!
  In order to make handling easier, you can clamp the power tool in the drill stand for diamond drills GCR 180. You must remove the auxiliary handle 12 before inserting the power tool into the drill stand. To do so, loosen the wing bolt for adjustment of the auxiliary handle 16 in an anticlockwise direction and slide the auxiliary handle down over the drill spindle 15.
  For mounting the power tool into the drill stand, please read and observe the operating instructions of the drill stand.

Inserting/Replacing the Core Bit

• Operation with drill stand: Before any work on the power tool, during work breaks, and when not using the power tool, secure the power tool against unintentional movement by tightening the locking brake. To do so, read and follow the operating instructions of the drill stand.

Core Bit Selection
Bosch core bits are color-coded:

Inserting a Core Bit

• Examine the core bit before inserting it. Use only core bits that are in perfect condition. Damaged or deformed core bits can lead to dangerous situations.
  Clean the core bit before inserting it. Apply a light coat of grease to the core bit thread or spray on a corrosion protection agent. Screw a 1 1/4″-UNC core bit 14 onto the drill spindle 15.
• Check the proper seating of the core bit. Incorrectly or insecurely fastened core bits can become loose during operation and may pose a danger.

Removing a Core Bit

• Wear protective gloves when replacing the core bit. The core bit can become hot after prolonged operation of the power tool.

Loosen the core bit 14 using an open-end spanner (size 41 mm). When doing so, hold a second open-end spanner (size 32 mm) on the two flats of the drill spindle 15 to provide a counterforce.

Connecting the Water Cooling/Dust Extraction
When wet- or dry-drilling core bits are not sufficiently cooled during drilling, the diamond segments can become damaged or the core bit can become jammed in the borehole. Therefore, provide for sufficient water cooling during wet drilling, and for proper operating dust extraction during dry drilling. When boring out a given bore, the given bore must be carefully plugged in order to enable sufficient cooling of the core bit.

• Connected hoses, shut-off valves, or accessories must not obstruct or hinder the drilling process.

Connecting the Water Cooling
Place the tap connection adapter 7 on the claw coupling 11 and tighten it all the way in a clockwise direction. Shut the water cock 9. Connect water supply to the water-outlet connector 8. The water supply is possible either via a mobile water-pressure container (accessory) or via a stationary water connection. If the power tool is inserted into a drill stand, you can collect the water escaping from the borehole using a water collection ring and a wet/dry vacuum cleaner (both accessories).

• When wet drilling overhead, the escaping water must be collected. To do this, insert the power tool into a drill stand and mount a water collecting ring. Read and observe the operating instructions of the water collection ring to mount it.

Connecting the Dust 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 in the user or bystanders.
  Certain dust, such as oak or beech dust, are considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.

–As far as possible, use a dust extraction system suitable for the material.
– 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 on.
Place the extraction adapter 6 on the claw coupling 11 and tighten it all the way in a clockwise direction. Attach the vacuum hose 4 of a wet/dry vacuum cleaner geared towards and recommended for this system (see “Accessories/Spare Parts”, page 15) to the vacuum connection 5.

Operation Starting Operation

• Observe the mains voltage! The voltage of the power source must correspond with the data on the type plate of the machine.
• Before beginning work, consult the structural engineer, architect, or construction supervisor in charge. Only cut through reinforcements with the permission of a structural engineer.
• When core drilling through walls or floors, ensure that you check the respective rooms/enclosures for obstructions. Barrier off the construction site and secure the drilled-out core against falling down with the use of casing or similar.

Function test of the portable residual current device (PRCD)
Each time before beginning work, check that the portable residual current device (PRCD) 3 is functioning properly:
– Press the “TEST” button on the portable residual current device (PRCD). The red control indicator extinguishes.
– Press the “RESET” button. It must now be possible to switch the power tool on. If the red control indicator does not extinguish when you press the “TEST” button or if it extinguishes repeatedly when the power tool is switched on, then you must have the power tool checked by an authorized Bosch after-sales service agent.

• If the portable residual current device (PRCD) is defective, the power tool must not be operated.
  Switching On
  Press the “RESET” button on the portable residual current device (PRCD) 3. Wet drilling: Set the water cock 9 to flow.
  To switch on the power tool, press the On/Off switch 1 and keep it pressed.
  To lock the pressed On/Off button, additionally press the lock-on button 2. To save energy, only switch the power tool on when using it.

Switching Off
Release the On/Off switch 1. When the On/Off switch 1 is locked, press the On/Off switch first and then release. Wet drilling: Shut the water cock 9. After finishing work, disconnect the water outlet connector 8 from the water supply. Open the water cock 9 and drain the remaining water.
Reduced starting current
The electronics of the power tool make the motor start softly, therefore preventing the starting current from being too high.
Restarting Protection
The restarting protection feature prevents uncontrolled restarting of the machine after an interruption in the power supply. To restart, press the “RESET” button on the portable residual current device (PRCD) 3. Then switch the On/Off switch 1 to the off position and switch the power tool on again.
Preselecting the Speed
Two speeds can be preselected using the gear selector 10. The gears are recommended for the following drilling diameters:

Working Advice

• Before any work on the machine itself, pull the mains plug.
  Always use a centering cross (accessory) when starting the drilling procedure without the use of a drill stand. Start drilling in 1st gear at low speed until the core bit rotates vibration-free in the material. Afterward switch to the 2nd gear, if required. While drilling, adapt the feed pressure to the material being drilled. Drill with uniform pressure. Lightly pull the core bit out of the bore from time to time so that the drilling sludge or drilling dust can be removed from the core bit segments.

Overload Clutch

• If the tool insert becomes caught or jammed, the drive to the drill spindle is interrupted. Because of the forces that occur, always hold the power tool firmly with both hands and provide a secure stance.

Overload Protection
If the overload threshold is exceeded, then the power tool will begin to pulsate noticeably. Reduce the feed pressure until the power tool works normally again. If the feed pressure is not reduced, then the power tool will switch off. You can then switch the power tool back on the straightaway, but you should continue to work with reduced feed pressure.

Removing the Core

Wet drilling: After drilling, continue to run the water for a short period in order to flush out the drilling sludge between the core bit and the core. If the drilling core is stuck in the core bit, then apply light blows onto the core bit with a piece of softwood or plastic in order to loosen the core.
If required, pry the drilling core out of the core bit using an appropriate hand tool (slotted screwdriver or similar).
Note: Do not hammer or apply blows onto the core bit with hard objects (danger of deformation)!

Maintenance and Service

Maintenance and Cleaning

• Before any work on the machine itself, pull the mains plug.
• For safe and proper working, always keep the machine and ventilation slots clean.

Clean the drilling spindle 15 after finishing work. Occasionally spray an anti-corrosion agent onto the drilling spindle and the core bit 14.
If the replacement of the supply cord is necessary, this has to be done by Bosch or an authorized Bosch service agent in order to avoid a safety hazard.
