KEEP-NUT™
DRILLING MACHINE
MANUAL
If the vacuum is unable to securely adhere to
the surface while drilling it is likely that the
Venturi has insufficient air pressure/volume.
With proper air flow the vacuum base should
have plenty of suction to stay in position during
use even while applying moderate force to the
handle while drilling. Check your air supply for
pressure and volume and make sure your airlines
are of sufficient diameter to supply the machine.
If proper air pressure is being supplied make
sure that the bit is properly dressed and cutting
freely. Do not apply excess pressure to the
handle during use. Excess pressure can damage
the
Alpha Air-680C
polisher and cause the
vacuum base to lose suction.
If the
KDM110
is drilling holes that are too large
for the keep-nut anchors, ensure the correct
bit is being used. If the correct bit is in use, you
may need to add a
5/8
”
washer between the
drill bit and the polisher to insure that the bit is
seated exactly 90° from the polisher. If the bit
has insufficient thread depth this can cause a
misalignment which will affect the final diameter
of the hole produced.
