Adjusting the side handle (fig. D)
To adjust the position of the side handle (4):
• Loosen the handle by unscrewing it (A).
• Rotate the handle to the desired position and
tighten it (B).
Always use the tool with the side handle
properly assembled.
Setting the drilling depth (fig. E)
• Insert the required drill bit as described above.
• Loosen the depth stop clamp (6).
• Fit the depth adjustment rod (5) through the hole
in the depth stop clamp.
• Adjust the drilling depth as shown.
• Tighten the depth stop clamp.
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.
Excessive force does not speed up
drilling but decreases tool performance
and may shorten tool life.
Drilling with a solid bit (fig. A)
• Set the mode selector (3) to the desired position:
hammer drilling for masonry, drilling only for
wood, metal and plastic, hammer only for
chipping and chiselling applications.
• Insert the appropriate drill bit.
• Adjust the side handle (4) as required.
• 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
variable speed switch (1).
• To stop the tool, release the switch.
Drilling with a core bit (fig. A)
• Set the mode selector (3) to the "hammer drilling"
position.
• Adjust the side handle (4) as required.
• Insert the appropriate core bit.
• Assemble the centerdrill into the core bit.
• Place the centerdrill on the spot and press the
variable speed 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.
Chipping and chiselling (fig. A)
• Before inserting the chisel, set the mode
selector (3) to the "hammering only with
spindle lock" position.
• Insert the appropriate chisel. To adjust the head of
the chisel to the desired angle, set the mode
selector (3) to the "bit rotation" position and rotate
the chisel by hand. Return the mode selector to
the "hammer only with spindle lock" position.
• Adjust the side handle (4) as required.
• Press the variable speed switch (1) and start
working.
• Do not use this tool to mix or pump
easily combustible or explosive fluids
(benzine, alcohol, etc.).
• Do not mix or stir inflammable liquids
labelled accordingly.
