• 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.

• 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) (DW541/DW545) 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. 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).

• 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.

appropriate accessories.
