Now that the lathe/mill is set up and you have
read the safety guidelines, it’s time to give each
motor a test run.
The purpose of the test run is to make sure the
lathe/mill is wired correctly and the motors are
working properly before proceeding with addi-
t
ional set up. Check to make sure that auto feeds
are not engaged, the chucks are secure in the
spindles, and there are no loose parts around
the spindles. Set the lathe/mill to the slowest
RPM before the test run. Refer to Control Panel
o
n Page 19, L
athe Speeds on Page 34, Mill
Speeds on Page 44, and L
ubrication on Page
51 before doing the test run.
The lathe and mill motors will be tested inde-
pendently.

sure the machine is properly ground-
ed, the power switch is turned OFF, and
both
reversing switches are set to the middle

the machine to ensure that all hand
tools are out of the way, guards are in place
and nothing is impeding the movement of
either chuck. Check this by rotating each by
hand.

The lathe should run smoothly with
little or no vibration or rubbing noises when it
starts. Strange or unnatural noises should be
investigated and corrected before operating
the machine further.

the lathe/mill is running correctly, turn the
reversing switch to the OFF position, wait for
the
machine to come to a complete stop.
