Caution
:
If the feed nut (8) is positioned on the lower part (10) of the drilling machine, interrupt the drilling
process, loosen the drill shaft (1) by opening the clamping screw (4) and turn the feed nut (8)
back to the red marking. Make sure that the drill shaft is NOT pulled back with it. Then fix the
drill shaft (1) again by tightening the clamping screw (4). Then continue the drilling process as
described.
Caution:
When the clamping screw (4) is opened, the pressure of the medium can cause the drill shaft
(1) to suddenly extend upwards. Therefore, make sure that the clamping screw is not opened
unintentionally during the entire drilling process.
1.3 Flushing
During and after the tapping process, the flushing tap (9) must be held in the open position until
all residual chips have flushed out.
1.4 After drilling
After drilling, pull the drill shaft (1) back a little by
turning the feed nut (8) to the left, open the clam-
ping screw (4) and pull back the drill spindle (1)
completely. Flush again if necessary.
Caution: When the clamping screw (4) is opened,
the pressure of the medium can cause the drill
shaft (1) to suddenly extend upwards.
• Move ZAK 69 waste water valve to closed
position
• Dismantle drilling machine (in reverse order to
assembly)
• Check whether the drilled out „tablet“ has been
held in the cup drill
1.5 Commissioning and pressure testing
After installation, please carry out a pressure test
in an open pipe trench in accordance with the re-
cognised rules of technology.
