Change Of Bits; Connection-Possibilities Of The Function Control - Deprag 397068 A Operating Instruction Booklet

4.3. Change of bits

Always disconnect the Screwdriver from air supply prior to
changing bits, to avoid the unintentional start of the Screw-
driver, which may result in injuries.
1. Unscrew spring sleeve (left-hand thread) – only necessary if a finder is
mounted.
2. After pulling the sleeve 351890 the bit may be removed or inserted.
Before exchange of bits, clutch bearing has to be in place.
Make sure to use perfect bits with DIN 3126 – E6,3 (1/4") ex-
ternal hexagon 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.)
