4. refer to page 32 for detailed instructions
for installing or removing the drill chuck and 
arbor in the spindle.
your machine includes an r-8 drill chuck arbor 
and Mt#3 drill chuck. Before use, the drill chuck 
must be installed onto the arbor. this drill chuck 
installation is intended to be semi-permanent. 
tip: For a permanent installation, chill the arbor 
in the freezer for 15 minutes before performing the 
following procedure. The taper will expand as it 
returns to room temperature, permanently locking 
the chuck.
to install the drill chuck onto the arbor:
1. Clean the grease off the drill chuck and all
taper mating surfaces. pay particular atten-
tion to the Mt#3 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 counterclockwise.
3. insert the arbor into the drill chuck. tap the
arbor lightly with a brass or other soft-headed 
hammer, as shown in 
figure 38 to get a
good fit.
note: While it may not seem like there is 
anything keeping the drill chuck in place, the 
MT#3 taper fit provides a strong bond and will 
hold the drill chuck tightly.
the Model g0705 includes two adapters that will 
allow the use of Mt#3 and Mt#2 tooling. a drift 
key is also included to aid in the separation of the 
adapters and any installed tooling.
use the adapters as necessary to fit the tooling 
you wish to install. if you are using a tool with an 
Mt#2 taper, you will need to use both adapters.
if the adapters become stuck together or tooling 
becomes stuck in one of the adapters, use the 
drift key to separate them.
to use the drift key:
1. disConneCt MaChine FroM poWer!
2. insert the pointed end of the drift key into the
adapter slot so that it is against the top end of 
the lodged adapter or tooling. 
3. support the lodged adapter or tooling with a
gloved hand to prevent it from falling out dur-
ing the next step.
4. gently tap on the broad end of the drift key.
the drift key's wedge shape will force out the 
lodged adapter or tooling.
