Note: Clamping lever 7 is indexed (adjustable), allowing it to
be set to an ergonomically favourable and space-saving posi-
tion.
With the clamping lever tightened, pull its lever away from the
motor unit, turn it to the desired position and allow it to en-
gage again.
Starting Operation
f Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On
– To activate the display 14, turn the On/Off switch 13 to
position .
– To start the machine, turn the On/Off switch 13 to
position .
The speed can now be set (see “Adjusting the Speed”,
page 22).
Switching Off
– To end the drilling, turn the On/Off switch 13 to
position .
or
– To completely shut-off the machine, turn the On/Off
switch 13 to position “0”.
Note: The machine is now de-energized. All current set-
tings for speed and drilling depth are deleted.
Quick-Stop Function
The Quick-Stop function enables swift switching off, e.g.,
when the application tool is jammed or locked-up in the work-
piece.
– Briefly and quickly press the On/Off switch 13.
The machine and the display are switched off immediately.
Note: The machine is now de-energized. All current set-
tings for speed and drilling depth are deleted.
– To restart the operation of the machine afterwards, the
On/Off switch 13 must be reset to position “0”.
Afterwards, the machine can be switched on again (On/Off
switch 13 in position ).
Restarting Protection
The restarting protection prevents uncontrolled starting of
the machine after a power failure (e.g., when the mains plug is
pulled during operation).
– To restart the operation of the machine afterwards, the
On/Off switch 13 must be reset to position .
Afterwards, the machine can be switched on again (On/Off
switch 13 in position ).
Temperature Dependent Overload Protection
When using the machine as intended for, it cannot be subject
to overload. In case of excessive loading or when exceeding
the allowable operating temperature, the electronics switch
the machine off until it is in the optimal operating-tempera-
ture range again.
– To restart the operation of the machine afterwards, the
On/Off switch 13 must be reset to position .
Afterwards, the machine can be switched on again (On/Off
switch 13 in position ).
Adjusting the Speed
f Set the correct speed before beginning to work. The
speed must be appropriate for the drilling diameter
and the material being drilled. When the speed is set in-
correctly, the application tool can become caught or jam in
the workpiece.
When adjusting the appropriate speed, please refer to the
speed diagram 6.
The diagram provides the speed (rpm) to be set dependent
on the drill bit diameter (Ø in mm) for the materials Steel and
Aluminium.
Gear Selection, Mechanical
Actuate the gear selector 21 only when the machine is at
a standstill.
Two speed ranges can be preselected with the gear selector
21.
1st gear:
Low speed range; for working with large drilling diameters.
2nd gear:
High speed range; For working with small drilling diameters.
– Set the gear selector 21 to the desired position.
Note: If the gear selector 21 cannot be turned to the stop,
turn the drill chuck a little.
Electronic Speed Control (see figure H)
With the speed regulator 15, the speed of the machine can be
variably adjusted.
– To start the machine, turn the On/Off switch 13 to
position .
– Press button 32 until “Speed” is indicated on the display.
– Turn the speed regulator 15 until the desired speed is indi-
cated on display 14.
Working Advice
General Information
Before drilling, make sure that the quick-clamping device 3,
the parallel guide 19 or the machine vice (accessory) are firm-
ly clamped/tightened.
When the drill bit comes out of the workpiece, it can become
caught or jam in the workpiece, and drag the workpiece along.
Therefore, reduce the feed at the end of the drilling phase.
If the application tool should become blocked, switch the ma-
chine off. Allow the application tool and the workpiece to cool
down. Remove the drilling chips/swarf. Determine the cause
of the application tool's jam and correct it.
Special Notes on Drilling in Metal
Centre-punch metal workpieces.
Pilot-drill when drilling diameters in excess of 10 mm.
To improve your work, use cutting oil (e.g. Bosch universal
cutting oil) to cool the drilling.
