Protool PDP 18-2 E-1 Originalbetriebsanleitung Seite 12

The locking is released again when the sleeve is
rotated in the opposite direction, in order to
remove the tool.
Caution! The drill chuck may be very hot:
During longer working periods, in
particular for impact drilling, the drill chuck
can become very hot. In this case we
recommend the use of protective gloves.
Switching on and off
Press the on/off switch (11) to switch on the
machine. Release again to switch off.
Continuous use
Switching on: Press the ON/OFF button (11),
hold and retain with the lock‑on button (12).
Switching off: Press and release ON/OFF
switch (11).
Speed Control
Lightly pressing the ON/OFF switch (11) results
in a low rotational speed, allowing a controlled
soft start.
Further pressure on the switch results in an
increase in speed.
Electronic speed pre-selection
The required speed can be pre‑selected with the
speed selector thumbwheel (10) (also possible
during operation).
The required speed depends on the material
being machined and can be determined by trial.
When putting a high load on the machine, always
set the speed selector thumbwheel (10) to the
maximum speed.
After long periods at low operating speed, run
the drill at high speed and without load for
approx. 3 minutes, in order to cool the machine
down.
Gear selection (Fig.)
Two speed ranges can be pre‑selected with the
gear selector switch (8):
1 Gear I: Lower speed range
2 Gear II: Higher speed range
The final speed can be electronically
pre‑selected within these speed ranges.
The gears can be switched when the machine
is running down or at a standstill, however not
under full load.

Changing rotational direction
Set the rotational direction switch (9) to the
right (lefthand rotation) or to the left (right‑hand
rotation). Operation in left‑hand rotational
direction enables applications such as tapping or
loosening bolts or nuts.
The rotational direction switch is locked when
the ON/OFF switch (11) is activated. Change the
rotational direction only when the machine is not
running.
CAUTION! When using the left run it is
especially important to firmly screw on the
chuck.
Normal and percussion drilling
Selector switch (4) can be felt snapping into
place, and can be actuated while the machine is
operating.
Drilling
Push selector switch (4) to the left.
Percussion drilling
Push selector switch (4) to the right.
Tungsten carbide drill bits are required for drilling
concrete, stone and masonry. The rotational
direction switch (9) must be in the clockwise
position.
Replacing the key-type drill chuck
(Fig.)
The drill chuck is secured with the securing
screw (20) against loosening from the drill
spindle. Open the drill chuck fully and completely
unscrew the securing screw (Caution: lefthand
thread!).
Set an open‑end spanner (size 17 mm) onto the
spanner surface (2) of the drill spindle and hold
tight. Insert the chuck key (16) into one of the
three holes of the drill chuck. Use the chuck key
as a lever to unscrew the drill chuck from the
spindle, by rotating in counterclockwise direction
against the open‑end spanner. A snug drill chuck
can be loosened by applying a light hammer
blow onto the drill chuck key (16).
Replacing the keyless chuck (Fig.)
The drill chuck is secured with the securing
screw (20) against loosening from the drill
spindle. Open the drill chuck fully and completely
unscrew the securing screw (Caution: lefthand
thread!). Clamp an Allen key (18) into the drill
chuck. Set an openend spanner (size 17 mm)
