2 Safety Instructions
2.1. Safety Instructions for Electronic Screwdrivers
Disconnect the machine from the power supply, prior to changing bits.
Do not wear loose clothing or jewelry; for movable parts can seize them.
Wear a hairnet, if operator has long hair.
Keep hands off the installed bit or socket.
Injury is possible, if the driver reacts with an unexpected motion or when driver is used
with a broken bit.
Injury is possible, if the driver or the installed bits/socket reacts with an unexpected mo-
tion.
When using tool with a bit-adapter or bit-extension (i.e. Magnetic Bit holder), make sure
that those items are in good condition and well suited for the application with this tool.
When installing driver into a support arm, make sure that the tool is rigidly mounted.
When not using any support arm or stand, place both feet securely on the floor. This
enables the Operator to easily absorb any tool reaction force.
Install a side-handle or counter-holder to the driver, if the reaction force
cannot safely be absorbed by operator.
After turning off the tool, the bit will continue to rotate (inertia).
In no case is it permissible to exceed the rated voltage.
In the case of a power interruption, it is necessary to reset the controller.
CAUTION
The screwdriver will heat-up in relation to its average load respectively
sequence of operation. If the selection of the type of screwdriver is incor-
rectly or its operation is not appropriate for the application, the tool might
overheat which could result in injuries (burnings).

This can be set via the menu Type of start (F05).
Delay interrupt Delay interrupt is set to prevent a screwdriving procedure being
recorded as cancelled if the start signal of the screwdriver is inter-
rupted and restarted within the set time. This is particularly impor-
tant in combination with a screw feeder to avoid errors when push-
ing the screw through the mouthpiece.
Torque mode There are two torque modes available for the screwdriver:
Torque setting in torque unit steps:
In this mode only program 1 is active as the screw assembly pro-
gram as well as program 6 as the loosening program. All parame-
ters (which had been adjusted in the menu) are used from program
1.
The shut-off torque for program 1 can be adjusted directly using the
program selection button.
The reversal button is used to start loosening program 6.
Select between adjustable screw assembly and loosening pro-
grams:
In this mode there are 5 screw assembly and 5 loosening programs
available which can be adjusted via the menu.
Use program selection to select between the programs 1 to 5.
Use the reversal to start the corresponding loosening program (e.g.
screw assembly program 2 -> Loosening program 7).
Password The screwdriver menu can be protected using a password. The
password can be set in the range 000 to 999.
If the password is set to 000 all menus are freely accessible.
It is set to 000 on delivery.
