7. Operation

en
-CAUTION-
Secure the workpiece. Use clamps or a vice to hold the
workpiece securely in position. It is then held more
safely and both hands remain free for holding and oper-
ating the tool.
7.1 Setting forward or reverse rotation
The forward / reverse switch is used to set the direction
of rotation of the drive spindle. An interlock prevents
operation of the switch while the motor is running.
– Push the forward / reverse switch to the left (as seen
when the tool is in use) = forwards.
– Push the forward / reverse switch to the right (as seen
when the tool is in use) = reverse.
7.2 Switching on / off
1. Plug the supply cord into the power outlet.
2. Press the control switch slowly. This allows the user
to select any speed between 0 and maximum.
-NOTE-
The drive spindle begins to rotate only when axial pres-
sure is applied to the tool.
7.3 Lockbutton for sustained operation
The lockbutton for sustained operating mode allows
continuous operation of the tool without need for apply-
ing constant pressure to the control switch.
7.3.1 Switching on in sustained operating mode
1. Press the control switch as far as it will go and hold
it in this position.
2. Press the lockbutton and then release the control
switch.
7.3.2 Switching off after sustained operation
3. Press the control switch. The lockbutton returns to is
its original position.
7.4 Interface for insert tools and accessories
1. Unplug the supply cord from the power outlet.
2. The depth gauge can be removed simply by pulling it
away from the tool (click connection). The drive spin-
dle is then exposed. The drive spindle must be exposed
(depth gauge removed) for the following operations:
– Using the tool to remove screws (reverse rotation)
– Changing bits
– Changing the bit holder
– Attaching the SMI 55 Plus magazine
– Tightening / redriving existing screws

7.5 Adjusting the depth gauge
-NOTE-
By adjusting the depth gauge, the screw can be driven
flush with the surface or left projecting. Each click-stop
equals an adjustment of ± 0.25 mm (see illustration).
7.5.1 To drive the screw deeper
1. Turn the depth gauge to the right.
7.5.2 To drive the screw less deeply
2. Turn the depth gauge to the left.
7.6 Removing the depth gauge

7.7 Changing insert tools
The chuck for holding insert tools (bit holder, bits etc.)
is of the standard (DIN 3126 / ISO 1173)
type. The screwdriving insert tools are held in place by
a spring mechanism.
1. Unplug the supply cord from the power outlet.
2. Remove the depth gauge by pulling it forward, away
from the tool.
3. The insert tool can then be pulled out and changed
(longer bit, bit holder, etc.).
4. Refit the depth gauge to the tool.
7.8 Removing a screw
Remove the depth gauge by pulling it forward, away
from the tool.
Set the forward / reverse switch to the reverse rotation
position.
The screw can then be removed.
