Application
Electropneumatic hammer drill is the device specified in particular
for impact drilling into concrete, stone and masonry, further on, for
impact-free drilling and screwing into wood, metal and plastics.
This electropneumatic hammer drill may be used for the purposes
above within the scope determined by the manufacturer.

Double insulation

To ensure maximum safety of the user, our tools are designed and
built to satisfy applicable European standards (EN standards). Tools
with double insulation are marked by the international symbol of
a double square. These tools must not be grounded and a two-wire
cable is sufficient to supply them with power. Tools are shielded in
accordance with EN 55014.
Supplementary handle assembly
Before any interference to the tool, disconnect the supply cable
first. Use the hammer only with supplementary handle (10). Mount
the handle to the fastening neck and secure with revolving grip.

Putting into operation

Connect only to a single-phase alternating current power network
with voltage marked on the nameplate. It is possible to connect
the tool even to outlets without a protective contact, as this is
a class II appliance.
Check, if the plug type corresponds with type of the outlet.
Switching ON and OFF
To switch the tool on, push the switch (4) and hold. The hammer
switches off as soon as you release the hold of the switch.
Rotation regulation
You can continuously change rotations with the switch (5). Push
the switch slightly and the hammer will start rotating slowly. The
stroger you push at the switch, the faster the rotation.
Function switch
The change-over switch of functions (6) has two positions:
Change the functions in the rest position only. Swivel the switch (6)
simply to the requested position.
The hammer drill gearbox will be switched to the selected position
after depressing the switch (4) and/or as soon as the hammer drill
is started.
Drilling and impact drilling
For drilling or screwing:
switch the function switch (6) onto the symbol
If you want impact drilling:
switch the function switch (6) onto the symbol
Notice: When impact drilling, do not change the speed to the
left to prevent drill damage. You can switch the speed to the
left only if the drill is jammed and you want to put it out of the
hole more easily. Use only and exclusively the recommended
drills with the SDS-Plus shank for impact drilling.
You cannot use the impact drills with the cylindrical shank speci-
fied for common chucks (quick-acting chucks or chucks with han-
dle) for this electropneumatic hammer drill.
