8.4 Safe operation 7
WARNING
Do not grip the power tool by the depth gauge or bit
holder. A screw coming into contact with a concealed
electric cable may result in electric shock.
8.5 Switching on / off
The speed of the power tool can be controlled smoothly
(increased from zero to maximum) by pressing the control
switch gradually.
8.6 Power tool overloading and overheating
indicator
NOTE
The power tool is equipped with an electronic protec-
tion system to prevent overloading and overheating. The
power tool switches itself off automatically in the event
of overloading and overheating. After releasing the con-
trol switch, the power tool may not restart immediately
when the switch is pressed again (while the power tool is
cooling down).
8.7 Lockbutton for sustained operation
NOTE
The lockbutton for sustained operation allows the motor
to run continuously without need for constant pressure
on the control switch.
8.7.1 Switching on in sustained operating mode 8
1. Press the control switch fully.
2. While maintaining pressure on the control switch,
press the lockbutton and then release the control
switch.
8.7.2 Switching off after sustained operation
Press the control switch. The lockbutton returns to its
original position.
8.8 Power tool / depth gauge interface 9
1. Pull the depth gauge away from the power tool,
releasing the click connection.
2. Pull the depth gauge forward, away from the power
tool.
With the drive spindle exposed in this way, the
following operations can be carried out: Removing
a previously-driven screw using reverse rotation,
changing the bit holder, changing to magazine op-
eration with the SMD 57 or redriving a screw. Read
the operating instructions for the magazine for infor-
mation about changing to magazine operation.
8.9 Removing a previously-driven screw
1. Remove the depth gauge or the magazine by pulling
it forward, away from the power tool.
2. Set the forward / reverse switch to the reverse
rotation position.
3. The screw can then be removed.
8.10 Reading the charge status LED display on
Li‑ion batteries 10
NOTE
The charge status cannot be indicated while the power
tool is in operation. If LED 1 blinks, this simply indicates
that the battery is either fully discharged or too hot for
use (temperature above 80°C).
The Li-ion battery features a charge status LED display.
The charge status is indicated by the LEDs on the battery
during charging (please refer to the operating instructions
for the charger). When the battery is at rest (not in use), its
charge status is indicated by the four LEDs on the battery
for three seconds after pressing one of the battery release
buttons.
8.11 Belt hook 11
CAUTION
Check that the belt hook is fitted securely before
beginning work.
The belt hook allows the power tool to be attached to
a belt worn by the operator. The belt hook can also be
fitted to the other side of the power tool for used by
left-handed persons.
1. Pull the battery out of the tool.
2. Fit the mounting plate into the guides provided.
3. Secure the belt hook with the two screws.
8.12 Universal hook
CAUTION
Check that the universal hook is fitted securely. Use
the universal hook only when required. Lay the power
tool down in a secure place when it is no longer in
use.
The universal hook can be used to attach the power tool
to the operator's belt or to other objects when not in use.
The universal hook can be removed from the power tool
if not required. To do this, release the two screws that
secure the universal hook to the power tool.
