Before any work on the machine itself, pull the
mains plug!
Connect the mains cable module to the handle. The
plug must latch.
Use the mains cable module provided only for
Kress Electro-Tools. Do not attempt to operate
other machines with the module.
Use only an original Kress mains cable module that is
at least of heavy rubber sheathed cable (Code desig-
nation H07 RN-F).
Check before putting into operation that the mains
voltage agrees with the voltage specified on the
nameplate of the machine.
SWITCHING ON/OFF
Press or release the on/off switch 8.
The on/off switch can be locked on with the locking
button 7. To release, briefly press and release the on/
off switch 8.
MECHANICAL GEAR SELECTION
With the gear selector/rotation stop switch 4, one of
three positions can be selected.
1 = Lower speed range: Hammer drilling, drilling
with normal twist drills in wood/metal over 8 mm dia.
and mixing work.
2 = Higher speed range: Drilling with normal twist
drills to 8 mm dia.
= No rotation: Light chiselling work.
The switch-over can best be performed at a standstill.
Please observe that the gear selector/rotation stop
switch 4 can be switched only one step at a time. Only
after the on/off switch 8 is actuated and the machine
starts does the gear box shift to the selected mode.
The gear selector/rotation stop switch 4 can only then
be switched again to the next position.
DRILLING - IMPACT DRILLING
For drilling, place the selector 10 in the
position.
For impact drilling, set to
.
The switch-over can best be performed at a standstill.
Only after the on/off switch 8 is actuated and the
machine starts does the gear box shift to the selected
mode.
Note: Left rotation when impact drilling damages the
drill. Switch off the impact mechanism for diamond
crown drilling or for mixing work.
For chiselling work, set the selector 4 to the
posi-
tion.
When hammer drilling, use exclusively drills with
hard metal inserts and SDS-Plus shafts. The use of
commercially available masonry drills with cylindrical
shafts by means of the adapter 14 and the normal drill
chuck in conjunction with the pneumatic impact mech-
anism is not possible.
SPEED CONTROL
With the on/off switch 8, the speed
can be continuously varied. With
light pressure on the on/off
switch 8, the machine begins to
rotate slowly; with increased pres-
sure, the speed increases.
SPEED PRESELECTION
With the knob 9, the speed in the gears 1 and 2 can
be continuously preselected also when the machine is
running.
Position A = lowest speed.
Position G = highest speed.
FULL WAVE ELECTRONIC SYSTEM WITH
TACHOMETER
The built in full wave electronic system with tachome-
ter maintains a constant rpm speed.
The electronic system also has a gradual start up
feature.
Even if the trigger-switch is fully depressed, the
machine will only reach its full rpm speed after approx.
1 second. This permits smooth drilling even when
working with sensitive materials.
ROTATIONAL DIRECTION SWITCHING
Operate the rotational direction
switch 6 only when the machine is
at a standstill!
Take hold of the rotational direction
switch 6 on both sides.
Right rotation: Set the rotational direction switch 6
to “R”.
Left rotation:
Set the rotational direction switch 6
to “L”.
Important!
Press the rotational direction
switch 6 through to the stop on the
housing each time, i. e., until it can
be felt to latch.
If the rotational direction switch 6 is set between the posi-
tions “R” and “L”, the machine cannot be switched on.

Operate the machine only with the auxiliary han-
dle 12. Place the auxiliary handle on the clamping
collar and tighten with the clamping screw.
