mation sheet. This could lead to a significant un-
derestimate of exposure when the tool is used
regularly in such a way.
NOTE: To be accurate, an estimation of the level
of exposure to vibration experienced during a
given period of work should also take into ac-
count the times when the tool is switched off and
when it is running but not actually doing the job.
This may significantly reduce the exposure level
over the total working period.
Intended Use
The machine is intended for drilling in wood,
metal, ceramic and plastic. Machines with elec-
tronic control and right/left rotation are also suit-
able for screwing and thread cutting.
Auxiliary Handle/Depth Stop
(see figure )
A
The auxiliary handle can be mounted on the right
or left side of the spindle neck with the wing
screw 9.
The drilling depth can be set with the depth
stop 10.
For this, loosen wing bolt for depth stop adjust-
ment 8, set the required drilling depth X and
tighten the wing bolt again.
The knurled surface on the depth stop 10 must
face upwards.
Inserting the Tool
Key Chuck (see figure
Open the chuck until the tool can be inserted.
Then, insert the tool.
Using the chuck key 12, tighten uniformly in all
three holes.
Keyless Chuck (see figure
Inserting the Tool
Hold the rear sleeve of the keyless chuck 1 tight
and open the chuck by turning the front sleeve,
until the tool can be inserted.
Tightening the Tool
Hold the rear sleeve tight and firmly tighten the
front sleeve by hand, until the locking ac-
tion ("click") is no longer heard. The drill chuck is
locked automatically.
The locking mechanism loosens when the sleeve
is turned in the opposite direction for removing
the tool.

Screwdriving Tools (see figure
The drill spindle 15 is equipped with a hexagon
socket for use with screwdriver bits 14. The bit
can be inserted directly into the drill spindle 15
when the chuck is removed, where it is retained
by a securing ring.
Initial Operation
Always use the correct voltage: The voltage of
the power source must agree with the values on
the nameplate of the tool.
Switching On and Off
To start the tool, press the On/Off switch 5 and
keep it pressed.
trolled starts. Do not strain the machine so
heavily that it comes to a standstill.
Lock the pressed On/Off switch 5 by pressing
the lock-on button 3.
To switch the tool off, release the On/Off
switch 5 or press and then release it.
Changing the Rotational Direction
Operate the rotational direction switch 6 only
at a standstill.
Set the rotational direction switch 6 to R (right-
hand rotation) or L (left-hand rotation). (When the
)
B
On/Off switch 5 is actuated, the rotational direc-
tion switch 6 is locked.)
The left-hand rotation enables screws or nuts to
be unscrewed.
Mechanical Gear Selection
)
C
Two speed ranges can be preselected with the
gear selector 7:
Gear I:
Gear II:
The speed can be switched during drilling opera-
tion. However, this should not be done while op-
erating at full load.
Speed Preselection
With the thumbwheel 4, the required speed can
be selected even if the machine is running.
English - 4
The machine runs with variable
speed between 0 and maximum
depending on the pressure applied
to the On/Off switch 5. Light pres-
sure results in a low rotational
speed, thus allowing smooth, con-
