Tool Specifications
Unscrewing chuck
(see figure
)
Loosen and unscrew the drill chuck with two
open-ended spanners as illustrated.
Mounting takes place in the reverse order.
Fitting the working tool
Before any work on the machine itself, pull the mains
plug.
Inserting the tool
Grip rear collar of keyless chuck
1
and rotate front col-
lar until chuck is open sufficiently for tool to be inserted.
Clamping the tool (see figure
)
Grip rear collar and manually rotate front collar until
tight. An audible "click" indicates that the chuck has
automatically locked.
The locking mechanism is automatically released when
the front collar is rotated in the opposite direction in
order to remove the tool.
Starting Operation
Always use the correct supply voltage:
The power sup-
ply voltage must match the information quoted on the
tool identification plate.
Mounting the Auxiliary Handle and the Mains Cable
Module
Auxiliary grip
11
is attached to spindle collar
3
.
Substantial torque reactions are possible when larger
drill bits are being used. Here the auxiliary grip pro-
vides extra safety.
Connect the mains cable module to the handle. The plug
must latch.
Switching on and off
Intermittant use:
Switching on: Press trigger switch
9
.
Switching off: Release trigger switch
9
.
Continuous use:
Switching on: Press the on-off switch
9
and then the
locking button
6
, after that release
on-off switch.
Switching off: Press the on-off switch
9
and then
release.
Restarting protection
Prevents uncontrolled restarting of the machine after a
power interruption.
Putting into operation again:
Switch on-off switch to off
position and switch on again.
Continuously Variable Speed Control
The speed can be infinitely varied by pressure on the
on-off switch up to the preselected level.
RPM Preselection (electronic)
The desired rotational speed can be preselected with
the thumbwheel
10
(also possible during operation).
After long periods at low operating speed, run the
machine at high speed and without load for approx.
3 minutes.
Changing rotational direction
Take hold of the rotational direction
switch
5
on both sides.
Set rotational direction selector
5
to
R (right or clockwise) or L (left or
anticlockwise). (Rotational direction
selector
5
is locked when ON-OFF
switch
9
is activated).
If the rotational direction switch
5
is set between the
positions “R” and “L”, the machine cannot be switched
on.
The reversing or anticlockwise opera-
tion enables application for tasks such
as loosening of screws.
Change rotational direction only when
machine is not running.
Electronic torque control
(Torque-Control)
Thumbwhee
l 7
can be used to determine the amount of
torque acting upon the drill spindle.
1 = low torque
10 = maximum torque
