INSTALLING
DRILL 8!TS {F_G Q)
1, Open the chuck jaws by hand turning the barrel ,of
the chuck (1) c_ockwise,
2, _nsert a dri!l bit into the ch_ far eao_,_gh to obtain

tighten the ddi! chuck sufficiently so the ddii b_tdoes
not s_ip whiie dtiiiir'_g.

ORtLUNG TO A SPEC|FIC DEPTH
Drilling a blind hole (not ell the way through the we;kpiece)
_o a given depth can be done two ways
Werkpiece method (RG_ R, S)
1 Mark the depth of the hole on the side of the

until the tip is even with the mark
3, Ho_d the feed handle at this pesitbn:
4. Spin the lower nut (3) d_n to contact the depth stop
lug (6) on the head
5, Spin the upper nut (5) down and tighten against the
lower _to (3)
6, The drill bit will know stop after traveling the distance
marked on the work#ece,
