• Do not carry the machine by the ca-
ble.
• The mains receptacles in the work-
ing area must be protected by a re-
sidual current circuit breaker (RC).
• For the attachment of identification
markings on the machine, do not
drill into the housing. The protective
insulation would be shorted. Use
stickers.
• When the drill unexpectedly jams,
the machine kicks back. Therefore,
always take a secure stance and
hold the machine firmly with both
hands.
Putting into Operation
Check before putting into operation
that the mains voltage agrees with
the voltage specified on the name-
plate of the machine.
Switching On/Off
Press or release the On/Off switch 6.
The On/Off switch can be locked on
with the locking button 7. To release,
briefly press and release the On/Off
switch 6.
Drilling - Impact drilling
For drilling, place the selector 4 in the
position.
For impact drilling, set to
. The
switch-over can best be performed at
a standstill. Only after the On/Off
switch 6 is actuated and the machine
starts does the gear box shift to the
selected mode.
Note: Left rotation when impact drill-
ing damages the drill.
When hammer drilling, use exclu-
sively drills with hard metal in-
serts and SDS-Plus shafts. The
use of commercially available ma-
sonry drills with cylindrical shafts by
means of the adapter 9 and the nor-
mal drill chuck in conjunction with the
pneumatic impact mechanism is not
possible.
Speed control
With the On/Off
switch 6, two speed
steps can be se-
lected.
For hole starting, press the On/Off
switch 6 lightly (hole starting step).
For full drilling performance, press in
the On/Off switch 6 completely.
Rotational direction switching
Operate the rota-
tional direction
switch 8 only when
the machine is at a
standstill!
Take hold of the rotational direction
switch 8 on both sides.
Right rotation:
Set the rotational direction switch 8
to “R”.
Left rotation:
Set the rotational direction switch 8
to “L”.
Important! Press the rotational di-
rection switch 8 in each case to the
stop on the housing, i. e. until it can
be felt to engage.
If the rotational direction switch 8
is set between the positions “R”
and “L”, the machine cannot be
switched on.
Inserting/Removing Tools
The tool holder 1 clamps the drilling
tools without using a tool key.
Inserting Tools
• Before any work on the machine
itself, pull the mains plug!
Clean and lightly grease the tool
shaft.
Pull back the unlocking collar 3. In-
sert the tool while turning into the tool
holder until it latches. Release the
unlocking collar. Check whether the
tool is firmly seated.
Take care that the dust protection
cap 2 is not damaged.
Replace damaged dust protection
caps!
Removing Tools
Slide the unlocking collar 3 to the
rear and pull out the tool.
Drill Chuck (Accessory)
For drilling work in metal, wood and
plastic with drills that have normal
shafts, a drill chuck (13 mm max.
chuck opening) is available. The drill
chuck is mounted on the adapter 9
(accessory) for screwdriver bits. All
common drill chucks with
1/2" x 20 UNF
internal
threads
(13 mm max. chuck opening) can be
used.
Mounting the chuck
• Before any work on the machine
itself, pull the mains plug!
Clean the threads of the drill chuck
(accessory) and the adapter 9 (ac-
cessory).
Screw the drill chuck onto the
adapter and tighten firmly (approx.
30 Nm). Clamp in a vise for tighten-
ing the adapter, for example. Clamp
an Allen key in the drill chuck and use
it to tighten the chuck. Then lock the
adapter in the tool holder the same
as a drill.
