Operating Instructions

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

• Auxiliary Handle

Operate your machine only with the auxiliary handle

Turn the bottom part of the auxiliary handle in counter clockwise direction and swivel the auxiliary handle to the desired position. Then retighten the bottom part of the auxiliary handle by turning in clockwise direction. Pay attention that the clamping band of the auxiliary handle is positioned in the groove on the housing as intended for.

• Adjusting the Drilling Depth

The required drilling depth can be set with the depth stop. Press the button for the depth stop adjustment and insert the depth stop into the auxiliary handle. The knurled surface of the depth stop must face downward. Insert the SDS-plus drilling tool to the stop into the SDS-plus tool holder. Otherwise, the movability of the SDS-plus drilling tool can lead to incorrect adjustment of the drilling depth. Pull out the depth stop until the distance between the tip of the drill bit and the tip of the depth stop corresponds with the desired drilling depth.

• Changing the Tool

The dust protection cap largely prevents the entry of drilling dust into the tool holder during operation. When inserting the tool, take care that the dust protection cap is not damaged. If damaged return the tool to your nearest BuildEquip Branch so that the dust protection cap can be changed immediately.

• Inserting SDS-plus Drilling Tools

The SDS-plus drill chuck allows for simple and convenient changing of drilling tools without the use of additional tools. Clean and lightly grease the shank end of the tool. Insert the tool in a twisting manner into the tool holder until it latches itself. Check the latching by pulling the tool. As a requirement of the system, the SDS-plus drilling tool can move freely. This causes a certain radial run-out at no-load, which has no effect on the accuracy of the drill hole, as the drill bit centres itself upon drilling.

• Removing SDS-plus Drilling Tools

Push back the locking sleeve and remove the tool.

• Setting the operating mode

The operating mode of the power tool is selected with the mode selector switch. To change the operating mode, push the release button and turn the mode selector switch to the requested position until it can be heard to latch.

Note: Change the operating mode only when the machine is switched off! Otherwise, the machine can be damaged.

• Reversing the rotational direction
  • The rotational direction switch is used to reverse the rotational direction of the machine. However, this is not possible with the On/Off switch actuated.
  • Right rotation: Turn the selector switch clockwise for drilling/hammer drilling on both sides to the stop in the position.
  • Left rotation: Turn the selector switch anti-clockwise for drilling/hammer drilling on both sides to the stop in the position.

Set the direction of rotation for hammer drilling always to right rotation.

• Switching On and Off

To start the machine, press the On/Off switch. To lock the On/Off switch, keep it pressed and additionally push the lock-on button. To switch off the machine, release the On/Off switch. When the On/Off switch is locked, press it first and then release it. To save energy, only switch the power tool on when using it.

• Setting the Speed/Impact Rate

The speed/impact rate of the switched on power tool can be variably adjusted, depending on how far the On/Off switch is pressed. Light pressure on the On/Off switch results in low speed/ impact rate. Further pressure on the switch increases the speed/impact rate.

• 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 for a secure stance. If the power tool jams, switch the machine off and loosen the tool insert. When switching the machine on with the drilling tool jammed, high reaction torques can occur.

Safety Warnings

• Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
• Always be sure you have a firm footing.
• Be sure no one is below when using the tool in high locations.
• Keep hands away from moving parts.
• Do not leave the tool running. Operate the tool only when hand-held.
• Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin.
• Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
• Use appropriate 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.
• Switch off the power tool immediately when the tool insert jams. Be prepared for high reaction torque that can cause kickback. The tool insert jams when: the power tool is subject to overload or it becomes wedged in the work piece. Hold the machine with a firm grip. High reaction torque can briefly occur while driving in and loosening screws.
• When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands.
• Secure the work piece. A work piece clamped with clamping devices or in a vice is held more secure than by hand.
• Keep your workplace clean. Blends of materials are particularly dangerous. Dust from light alloys can burn or explode.
• 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.
• 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.
