4.3. Change of Bits
Attention:
Prior to changing bits, the clutch bearing and the reduction gear
have to be in place and the screwdriver needs to be
disconnected from the air supply.
·
The reduction gear is serially equipped with a quick change chuck.
·
In order to changing bits, pull the sleeve 331473 forward, the bit can now
be removed or inserted.
·
Make sure to use perfect bits with DIN 3126 – E6,3 (1/4”) external hexa-
gon end only.

4.4. Connection-Possibilities of the Function Control
·
Use as air pressure outlet during screw-assembly:
-
to control driver start and stop, as well as shut-off control of clutch;
-
as cycle counter of the complete process;
each in connection with a PE- Switch or similar.
·
Use as air pressure inlet:
-
if 6,3 bar (90 PSI) air pressure is given to the function control port, the
driver starts rotating at about 15 % of its speed. This will simplify the
engagement of bit/socket to fastener (for example when driving hex
screws, nuts, etc.)
