Rotary Drilling (fig. 1)
  1. Hold down the mode selector button (e) then 
set the mode selector switch (d) to the “rotary 
drilling” position.
  2. Depending on your tool, follow either of the 
following instructions:
 –  D25032, D25033, D25133, D25263: Fit the 
chuck adapter/chuck assembly.
 –  D25134, D25144: Replace the SDS Plus tool 
holder with the keyless chuck.
  3. Proceed as described for hammerdrilling.
 
 WARNING: Never use standard chucks 
in the hammerdrilling mode.
Screwdriving (fig. 1)
  1. Hold down the mode selector button (e) then 
set the mode selector switch (d) to the rotary 
drilling position.
  2. Select the direction of rotation.
  3. Depending on your tool, follow either of the 
following instructions:
 –  D25032, D25033, D25133, D25263: Insert 
the special SDS Plus screwdriving adaptor for 
use with hexagonal screwdriver bits.
 –  D25134, D25144: Replace the SDS Plus tool 
holder with the keyless chuck 
  4. Insert the appropriate screwdriver bit. When 
driving slotted head screws always use bits with 
a finder sleeve.
  5. Gently press the variable speed switch (a) to 
prevent damage to the screw head. In reverse 
(LH) rotation the tool speed is automatically 
reduced for easy screw removal.
  6. When the screw is flush with the workpiece, 
release the variable speed switch to prevent 
the screw head from penetrating into the 
workpiece.
Chipping and Chiselling (fig. 1)
D25033, D25133, D25134, D25144, D25263
  1. Hold down the mode selector button (e) 
then set the mode selector switch (d) to the 
“hammering only” position.
  2. Insert the appropriate chisel and rotate it by 
hand to lock it into position.
  3. Adjust the side handle (h) as required.
  4. Switch on the tool and start working.
  5. Always switch off the tool when work is finished 
and before unplugging. 
Switching On and Off (fig. 1)
  1. To run the tool, press the variable speed switch 
(a). The pressure exerted on the variable speed 
switch determines the tool speed.
  2. For continuous operation, press and hold down 
the variable speed switch.
  3. To stop the tool, release the switch.
Hammerdrilling (fig. 1)
DRILLING WITH A SOLID BIT
  1. Hold down the mode selector button (e) 
then set the mode selector switch (d) to the 
hammerdrilling position.
  2. Insert the appropriate drill bit. 
 NOTE: For best results use high quality carbide-
tipped bits.
  3. Adjust the side handle (h) as required.
  4. If necessary, set the drilling depth.
  5. Mark the spot where the hole is to be drilled.
  6. Place the drill bit on the spot and switch on the 
tool.
  7. Always switch off the tool when work is finished 
and before unplugging.
DRILLING WITH A CORE BIT
  1. Hold down the mode selector button (e) 
then set the mode selector switch (d) to the 
hammerdrilling position.
  2. Adjust the side handle (h) as required.
  3. Insert the appropriate core bit.
  4. Assemble the centerdrill into the core bit.
  5. Place the centerdrill on the spot and press the 
on/off switch (a). Drill until the core penetrates 
into the concrete approx. 1 cm.
  6. Stop drilling and remove the centerdrill. Place 
the core bit back into the hole and continue 
drilling.
  7. 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 center drill completely 
through the structure. Then drill the cored hole 
halfway from each side.
  8. Always switch off the tool when work is finished 
and before unplugging.
