To test run the machine:
1. Set spindle direction switch to neutral
("0" position), and turn speed adjusting
knob all the way counterclockwise to "0".
Fig. 09
2. Shift High/Low range lever on back to
low and feed direction lever to neutral.
Fig. 10
3. Make sure chuck and jaws are secure.
4. Disengage half nut with lever. Fig. 11
5. Release Emergency Stop button and
press "I" button. The spindle speed
display and power light should illuminate
to indicate that lathe is connected to
power supply.
6. Verify lathe is operating correctly by
turning spindle direction switch to "F"
position. Slowly turn speed adjusted
knob clockwise until spindle speed
display shows 100 RPM. The spindle
should rotate counterclockwise-- down
and toward the front of the lathe.
7. Push Emergency Stop button to turn lathe
OFF. Then, without resetting Emergency
Stop button, try to restart spindle rotation
by turning speed adjusting knob all the
way counterclockwise to "0" and then
clockwise. The spindle should not start.
If spindle does start with Emergency Stop button
pressed in, the button is not operating correctly.
This safety feature must operate properly before
continuing operation.
The test run is complete. Turn lathe OFF
and perform the following Spindle Break-In
procedure.
Spindle Break-In
To perform the spindle break-in
1. Successfully complete the Test Run.
2. Set spindle direction switch to "F"
(forward), ensure range lever is in LOW,
and operate lathe for 10 minutes at 100
RPM.
3. Operate lathe at 1000 RPM for 10
minutes, then turn variable speed dial to
"0" to stop spindle.
4. Shift range control lever to HIGH, then
operate lathe at 2000 RPM for 10
minutes, then stop spindle.
5. Run lathe in reverse at 2000 RPM for 10
minutes, then turn speed dial to "0", turn
spindle direction switch to "0", and press
Emergency Stop button.
Spindle break-in is complete.
Chuck Installation Fig. 12
To ensure accurate work, it is extremely
important to make sure the spindle nose and
chuck mating surfaces are clean. Even a small
amount of lint or debris can aff ect accuracy.
The chuck is properly installed when it is seated
against the backplate shoulder.
To install the chuck Fig. 13-14
1. DISCONNECT LATHE FROM POWER!
2. Use anappropriate device to protect
ways during installation process.
3. Thoroughly clean and wipe-down all
mating surfaces with a lightly-oiled, lint-
free rag.
4. Insert chuck screws through mounting
holes in spindle backplate, as shown in
Fig. 13. Make sure chuck seats fi rmly
and evenly against backplate shoulder.
Fig. 13
5. Use a lock washer and hex nut on each
chuck screw to secure chuck (see Fig.
14)
Tighten hex nuts evenly a small amount
at a time in multiple steps. Fig. 14
Changing Jaw Set
The 3-jaw chuck included with the lathe features
inside and outside hardened steel jaw sets which
move in unison to center a concentric workpiece.
When installing the jaws, it is important to make
sure they are seated correctly. Fig. 15
Jaws are numbered from 1–3. The number is
typically stamped on the side or bottom. Fig. 16
To change jaw set
1. DISCONNECT
POWER!
2. Insert
chuck
counterclockwise to back jaws out and
remove them individually in descending
order (3, 2, 1).
3. Use mineral spirits to clean debris and
grime from jaws and chuck jaw guides.
4. Rotate chuck key clockwise until you see
tip of outer scroll-gear lead thread about
to enter a jaw guide. Fig. 17
