drill chuck arbor

your machine has been pre-fitted with a drill
chuck arbor that has an r-8 shank and a Jacob's
taper. it is ready to accept the standard drill
chuck provided with this machine. this drill chuck
installation is intended to be permanent.
to install the drill chuck:
1. Clean the grease off the drill chuck and all
taper mating surfaces. pay particular atten-
tion to the bore in the drill chuck—it must be
free from all grease, oil and debris.
2. retract the drill chuck jaws fully by turning the
body of the drill chuck clockwise.
3.
press the drill chuck onto the Jacob's taper.
tap lightly with a brass or other soft-headed
hammer to get a good fit.
note: While it may not seem like there is
anything keeping the drill chuck in place, the
Jacob's Taper fit provides a strong bond and
will hold the drill chuck tightly (figure 14).

all types of milling cutters and drill bits are
sharp. it is recommended that these not
be handled directly. use leather gloves or
shop towels to hold sharp tooling to avoid
cuts to your hands. be careful while han-
dling them and store them in a child safe
location.
the Model g3358 comes equipped with a 3" face
mill and a 1" r-8 stub arbor. if they are not already
