E N G L I S H
• 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.
en - 6
• 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.
