Diamond drill safety warnings

• When performing drilling that requires the use of water, route the water away from the operator’s work area or use a liquid collection device. Such precautionary measures keep the operator’s work area dry and reduce the risk of electrical shock.

• Operate power tool by insulated grasping 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.

• Wear hearing protection when diamond drilling. Exposure to noise can cause hearing loss.

• When the bit is jammed, stop applying downward pressure and turn off the tool. Investigate and take corrective actions to eliminate the cause of the bit jamming.

• When restarting a diamond drill in the workpiece check that the bit rotates freely before starting. If the bit is jammed, it may not start, may overload the tool, or may cause the diamond drill to release from the workpiece.

• When securing the drill stand with anchors and fasteners to the workpiece, ensure that the anchoring used is capable of holding and restraining the machine during use. If the workpiece is weak or porous, the anchor may pull out causing the drill stand to release from the workpiece.

• When securing the drill stand with a vacuum pad to the workpiece, install the pad on a smooth, clean, non-porous surface. Do not secure to laminated surfaces such as tiles and composite coating. If the workpiece is not smooth, flat or well affixed, the pad may pull away from the workpiece.

• Ensure there is sufficient vacuum before and during drilling. If the vacuum is insufficient, the pad may release from the workpiece.

• Never perform drilling with the machine secured by the vacuum pad only, except when drilling downwards. If the vacuum is lost, the pad will release from the workpiece.

• When drilling through walls or ceilings, ensure to protect persons and the work area on the other side. The bit may extend through the hole or the core may fall out on the other side.

• Do not use this tool for overhead drilling with water supply. Water entering the power tool will increase the risk of 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 explosion. Penetrating a water line causes property damage or may cause an electric shock.

• Wear non-skid shoes. This prevents injuries that can occur from slipping on smooth surfaces.

• Never operate the power tool without the portable residual current device (PRCD) included in delivery.

• Before beginning work, check that the portable residual current device (PRCD) is functioning properly. Have any damaged portable residual current devices (PRCDs) repaired or replaced by a Bosch after-sales service centre.

• Pay attention that neither persons in the working area nor the power tool itself come into contact with the water that comes out.

• Products sold in GB only: Never operate the 110 V execution of the machine without 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.

• Never leave the tool unattended before it has come to a complete stop. Cutting tools that are still running can cause injuries.

• Assemble the drill stand properly before mounting the drill. The correct assembly is important in order to ensure proper function.

• Ensure that the drill is securely attached to the drill stand before using it. Otherwise, the drill may slip in the drill stand, which can lead to a loss of control.

• Secure the drill stand on a stable and even surface. If there is a chance that the drill stand will slip or wobble, the safe and steady operation of the drill cannot be guaranteed.

• Keep the drill cord away from the work area. Damaged or entangled cords increase the risk of electric shock.

• Do not overload the drill stand or climb or stand on it. Overloading or standing on the drill stand can raise its centre of gravity, causing it to tip over.

• Store idle drill stands out of the reach of children. Do not allow persons unfamiliar with the tool or these instructions to operate the tool. Tools can be dangerous in the hands of untrained users.

• Before carrying out any work on the drill stand or drill, during work breaks and when not using the drill stand, secure the drill stand against unintentional movement by tightening the parking brake.

• The power tool must only be operated on a mains supply with protective conductor and adequate dimensioning.

• Always fasten the drill stand while in operation, using anchors or vacuum (accessory) to prevent accidental tipping of the drill stand with inserted diamond drill and core bit.

• 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.
