REPLACEMENT PARTS  

move tube 1 slightly above the standard setting.  Check
the alignment again and adjust accordingly.

Drill bit backing up into chuck during sharpening
procedure: Follow the chuck disassembly procedure on
page 7 of the ops manual. Using compressed air, a small
brush or rag, wipe between the white/black pusher (the
pusher is the piece holding the jaws and springs) and the
chuck knob.  Rotate the knob to make sure all dust/grit is
removed. Reinstall chuck body to chuck knob; ensuring
the jaws are in the jaw grooves.  

Slow and Fast Spiral / Helix Drill Bits, Raised
Margin Drill Bits & Negative Relief: Using the stan-
dard drill setting align the bit in the chuck.  Visually
check the alignment of the bit before sharpening.  Note
the position of the two chuck flats, (remember the flats
are what lock the chuck in the alignment & splitting
tubes).  Draw an imaginary line from the middle of the
flat up through the drill bit.  That line should end up  on
the heel of the drill bit (see Figure 29).  This check will
hold true on drill bits from 3/32” to 1/2”.  If the line
does not fall on the heel, then the alignment tube must
be adjusted.  If the line falls to the right of the heel,
move tube

slightly below the standard setting.  The

chisel edge will rotate clockwise if the alignment set-
ting is moved too far.  If the line falls left of the heel
