Soft start feature

The soft start feature allows to build up speed slowly, thus preventing the drill bit from walking off the intended hole position when starting. The soft start feature also reduces the immediate torque reaction transmitted to the gearing and the operator if the hammer is started with the drill bit in an existing hole.

Torque limiting clutch

All Rotary Hammers are equipped with a torque limiting clutch that reduces the maximum torque reaction transmitted to the operator in case of jamming of a drill bit. This feature also prevents the gearing and electric motor from stalling. The torque limiting clutch has been factory-set and cannot be adjusted.

Electronic speed and impact control (fig. B)

The electronic speed and impact control (2) offers the following advantages:

• use of smaller drill bits without risk of bit breakage
• drilling into light and brittle materials without shattering
• optimal tool control for precise chiselling

Service and power-ON indicator LEDs (fig. B)

The red service indicator LED (3) lights up when the carbon brushes are nearly worn out to indicate that the tool needs servicing. After approx. 8 hours of use the motor will automatically be shut off. The carbon brushes are not user-serviceable. Take the tool to an authorized BERNER repair agent.

Electrical safety

The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the voltage on the rating plate.

Your BERNER tool is double insulated in accordance with EN 50144; therefore no earth wire is required.

Mains plug replacement (U.K. & Ireland only)

• Should your mains plug need replacing and you are competent to do this, proceed as instructed below. If you are in doubt, contact an authorized BERNER repair agent or a qualified electrician.
• Disconnect the plug from the supply.
• Cut off the plug and dispose of it safely; a plug with bared copper conductors is dangerous if engaged in a live socket outlet.
• Only fit 13 Amperes BS1363A approved plugs fitted with the correctly rated fuse (1).
• The cable wire colours, or a letter, will be marked at the connection points of most good quality plugs. Attach the wires to their respective points in the plug (see below). Brown is for Live (L) (2) and Blue is for Neutral (N) (4).
• Before replacing the top cover of the mains plug ensure that the cable restraint (3) is holding the outer sheath of the cable firmly and that the two leads are correctly fixed at the terminal screws.

Never use a light socket.

Never connect the live (L) or neutral (N) wires to the earth pin marked E or

For 115V units with a power rating exceeding 1500 W, we recommend to fit a plug to BS4343 standard.

Using an extension cable

If an extension cable is required, use an approved extension cable suitable for the power input of this tool (see technical data). The minimum conductor size is 1.5mm^2

When using a cable reel, always unwind the cable completely.

Also refer to the table below.

Assembly and adjustment

Prior to assembly and adjustment always unplug the tool.

Setting the electronic speed and impact control dial (fig. B1 & B2)

• 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. (BHD-5 from "1" to "5")

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. D1 & D2)

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. D2):

• Turn the option lever (4) so that it points upwards.
• Turn the cutter to the desired position.
• Rotate the mode selector (4) until it points to the T-symbol.
• In this mode the Rotary Hammer can also be used as a lever to free a jammed drill bit.
• Turn the cutter till it snaps in its position.

Inserting and removing SDS-max® accessories (fig. C1 & C2)

These models use SDS-max® drill bits and chisels (refer to the inset in fig. C2 for a cross-section of an SDS-max® bit shank).

• Unplug the tool.
• 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 (fig. E1-E4)

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.

Mounting in front position (fig. E1 & E2)

• Snap the steel ring (16) over the collar (7) behind the tool holder (6). Squeeze both ends together, mount the bush (14) and insert the pin (15).
• Place the side handle clamp (13) 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. E2) for optimum control.
• Lock the side handle mounting assembly in place by tightening the clamp wheel (9).

Mounting in rear position (fig. E3 & E4)

The rear position is particularly useful when drilling overhead or down into a floor. Refer to fig. D4.

• 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. F)

• Insert the required drill bit.

• Loosen the clamp nut (17) 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 (17).

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. 20kg ). 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 (4) 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 (4) 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.

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)

• Set the electronic speed and impact control dial (2).
• Select the type of operation - Turn the option level (5) to "cut only".
• 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.
