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. DW541/DW545 - Electronic speed and impact control (fig. B) The electronic speed and impact control 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 DW541/DW545 - Service and power-ON indicator LEDs (fig. B) The red service indicator LED (4) 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 DEWALT repair agent. The green power-ON indicator LED (3) lights up when the tool is switched ON. If the indicator LED is lit but the tool does not start, the electrical motor may be defective. If the indicator LED does not light up and the tool does not start, the ON/OFF-switch or the mains cord may be defective. 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 DEWALT 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 DEWALT 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 115 V tools, use plugs to BS4343 standard. Using an extension cable If an extension cable is required, use an approved triple-core extension cable suitable for the power input of this tool (see technical data). The minimum conductor size is 1.5 mm

When using a cable reel, always unwind the cable completely. Also refer to the table below.19 ENGLISH en - 5 Hammering only with spindle lock: impacting only - for light chipping, chiselling and demolition applications. SDS-max

Assembly and adjustment Prior to assembly and adjustment always unplug the tool. DW541/DW545 - 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.20 ENGLISH en - 6

• 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.

• 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). 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) (DW541/DW545).

• Set the mode selector lever (5) to the “hammer drilling” position.

• 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) (DW541/DW545) to medium or high speed position.

• Set the mode selector lever (5) to the “hammer drilling” position.

• 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) (DW541/DW545).
