Test Run
Once the machine has been permanently placed
and cleaned off, test run your machine to make
sure it runs properly.
If, during the test run, you cannot easily locate
the source of an unusual noise or vibration, stop
using the machine immediately, then review the
Troubleshooting on Page 47. If you still cannot
remedy a problem, contact our Tech Support at
(570) 546-9663 for assistance.
To test run the machine:
1. Make sure you have read the safety instruc-
tions at the beginning of the manual and that
the machine is set up properly.
2.
Make sure all tools and objects used during
setup are cleared away from the machine.
3. Make sure that your mill is lubricated (refer to
Lubrication beginning on Page 42).
4. Move the spindle speed range lever to the low
position (see Figures 31 & 32 on Page 33 for
location).
5. Ensure the manual/power downfeed selec-
tor is in the manual or "hand" position (refer
to Downfeed Operations on Page 35 for
detailed instructions).

Connect the machine to the power source.
7. Turn the machine ON by turning the forward/
reverse switch.
8.
Listen to and watch for abnormal noises or
actions. The machine should run smoothly
with little or no vibration or rubbing noises.
— Strange or unusual noises must be inves-
tigated and corrected before operating the
machine further. Always disconnect the
machine from power before investigating
or correcting potential problems.

ward/reverse switch to the middle position.
Your milling machine comes with a power feed
unit for X-axis table travel. The limit switch for
this table travel direction is important for the safe
operation of your mill.
To test the power feed unit and table limit
switch:
1. Make sure all tools, cables, and other items
are well clear of table movement as you fol-
low these steps.
2. Refer to Table Movement beginning on
Page 28 to understand how the power feeds
and limit switches function.
