Loosen base locking screw and move motor unit up or down to
decrease or increase depth of cut.
It may be necessary with some bits to withdraw bit
from collet to obtain maximum depth of cut. When doing this be
sure at least
1
/2
" of bit shank is engaged in collet. Do not use bits
that result in having less than
1
/2
" of bit shank engaged in collet. To
do so may cause poor gripping of collet resulting in loose bit and
damage to work, or personal injury should the bit come out of collet.
