ENGLISH Assembly and adjustment
Prior to assembly and adjustment always unplug the tool. Setting the electronic speed and impact control dial (fig. B) Turn the dial (2) to the desired level. The higher the number, the greater the speed and impact energy. With dial settings from 1 (low) to 7 (full power) the tool is extremely versatile and adaptable for many different applications. The required setting is a matter of experience. E.g. when using smaller diameter bits or when drilling into ceramic or brittle materials, set the dial to position 1 (low). Selecting the operating mode (fig. B) Your Rotary Hammer can be used in two operating modes: Hammer drilling: simultaneous rotating and impacting - for all concrete and masonry drilling operations. Hammering only with spindle lock: impacting only - for light chipping, chiselling and demolition applications. SDS-max chisels can be locked into 8 different positions (also refer to fig. C): Rotate the mode selector (5) until it covers the safety lock (16). Lock the chisel in the required position. Rotate the mode selector (5) until it points to the -symbol. In this mode the Rotary Hammer can also be used as a lever to free a jammed drill bit. Select the required operating mode by rotating the mode selector lever (5) over the safety lock (16) until it points to the symbol. Inserting and removing SDS-max accessories (fig. C) These models use SDS-max drill bits and chisels (refer to the inset in fig. C for a cross-section of an SDS-max bit shank). Unplug the tool. Mounting in front position (fig. D) Unscrew the side handle (8) and disassemble the side handle clamp (20). Snap the steel ring (17) over the collar (7) behind the tool holder (6). Squeeze both ends together, mount the bush (18) and insert the pin (19). Place the side handle clamp (20) and screw on the clamp wheel (9). Do not tighten. Screw the side handle (8) into the clamp wheel and tighten it. Rotate the side handle mounting assembly to the desired position. For drilling horizontally with a heavy drill bit, place the side handle at an angle of approx. 20 (refer to fig. E) for optimum control. Lock the side handle mounting assembly in place by tightening the clamp wheel (9). Mounting in rear position (fig. F) The rear position is particularly useful when drilling overhead or down into a floor. Refer to fig. G. Unscrew the side handle (8) and remove it from the front position. Leave the side handle mounting assembly in front position so that the depth adjustment rod can still be used. Screw the side handle directly into one of the rear side handle positions (10) on either side of the tool. Setting the drilling depth (fig. H) Insert the required drill bit. Insert the bit shank into the tool holder locking sleeve (6) and turn the bit slightly until the sleeve snaps in position. Pull on the bit to check if it is properly locked. The hammering function requires the bit to be able to move axially several centimetres when locked in the tool holder. To remove a bit pull back the tool holder locking sleeve (6) and pull the bit out of the tool holder. Assembling and fitting the side handle The side handle (8) can be mounted in front or in rear position on either side of the Rotary Hammer to suit both RH- and LH-users. Always operate the Rotary Hammer with the side handle properly assembled.

Loosen the clamp nut (21) and fit the depth adjustment rod (11) through the hole in the side handle clamp. Push the drill bit into a surface at a right angle and adjust the depth adjustment rod (11) as shown. Tighten the clamp nut (21). To avoid unwanted breaking away of concrete around the hole, first drill a hole the diameter of the centerdrill completely through the structure. Then drill the cored hole halfway from each side. To stop the tool, proceed as described above. Chipping and chiselling (fig. A)

Instructions for use

Always observe the safety instructions and applicable regulations. Be aware of the location of pipework and wiring. Apply only a gentle pressure to the tool (approx. 20 kg). Excessive force does not speed up drilling or chiselling but decreases tool performance and may shorten tool life. Drilling with a solid bit (fig. A) Set the electronic speed and impact control dial (2). Set the mode selector lever (5) to the hammer drilling position. Insert the appropriate drill bit. Fit and adjust the side handle (8). If necessary, set the drilling depth. Mark the spot where the hole is to be drilled. Place the drill bit on the spot and press the ON/OFF-switch (1). To stop the tool, release the ON/OFF-switch (1). Always switch off the tool when work is finished and before unplugging. Drilling with a core bit (fig. A) Turn the electronic speed and impact control dial (2) to medium or high speed position. Set the mode selector lever (5) to the hammer drilling position. Fit and adjust the side handle (8). Insert the appropriate core bit. Assemble the centerdrill into the core bit. Place the centerdrill on the spot and press the ON/OFF-switch (1). Drill until the core penetrates into the concrete approx. 1 cm. Stop drilling and remove the centerdrill. Place the core bit back into the hole and continue drilling. When drilling through a structure thicker than the depth of the core bit, break away the round cylinder of concrete or core inside the bit at regular intervals.
Set the electronic speed and impact control dial (2). Set the mode selector lever (5) to the hammering only with spindle lock position. Insert the appropriate chisel and rotate it by hand to lock it into one of 8 positions. Fit and adjust the side handle (8). Press the ON/OFF-switch (1) and start working. To stop the tool, proceed as described above. Various types of SDS-max drill bits and chisels are available as an option. Consult BERNER for further information on the appropriate accessories.
