OPERATION
Fig. 10
Fig. 11
• Continue to apply only sufficient pressure to allow the
cutter to cut freely through the work piece.
• Depending on the thickness of the workpiece periodically raise
the cutter to clear the swarf build up prior to continuing the cut.
WARNING: On completion of the cut the pilot pin will eject
the material slug. This slug will be very hot with sharp edges.
Use protective gloves if slug requires handling.
If the slug fails to be ejected from the cutter this could be
caused by the slug becoming twisted inside the cutter. To
release the slug lower the cutter onto a flat area of the work
piece, this will square up the slug and allow it to be ejected.
AUXILIARY 13mm 3 JAW CHUCK.
(UK Market only)
This machine is supplied with an auxiliary 3 jaw chuck to
enable the use of standard parallel shank twist drill bits.
Note: When fitted, the 3 jaw chuck (and any twist drill fitted into
it) are considerably longer than any of the annular cutters usually
fitted into this machine. To accommodate this greater overall length
the secondary slide facility of the machine must be employed.
The locking lever for the secondary slide has a left hand thread
and is found on the lower Left Hand side of the gearbox
housing. (Fig. 9) Loosen this lever to adjust the height (length)
of the machine (max 670mm) to suit the drilling application.
Once adjustment has been satisfactorily completed, ensure that
the secondary slide is securely tightened using the locking lever.
To fit the chuck:
• Screw the 3 jaw auxiliary chuck into the threaded bore of
the chuck adaptor. (Fig. 10)
• Align the two flats on the chuck adaptor with one of the
screws in the spindle. (Fig.11)
• Start to tighten the grub screw and at the same time slightly
rotate the chuck adaptor backwards and forwards until the
grub screw is fully tightened. This will ensure that the grub
screw is located squarely onto the flat preventing the chuck
adaptor from becoming loose.
• Tighten the remaining grub screw.
