Power Connection
Electrocution or fire can occur
if machine is ungrounded,
incorrectly connected to
power, or connected to an
undersized circuit. Use an
electrician or a qualified ser-
vice personnel to ensure a
safe power connection.
Before the machine can be connected to the
power supply, there must be an electrical cir-
cuit that meets the Circuit Requirements on
Page 13, and the correct plug must be installed
according to the instructions and wiring diagrams
provided by the plug manufacturer.
If the plug manufacturer did not include instruc-
tions, the wiring of a generic NEMA 6-15 plug is
illustrated in the Wiring section on Page 63.
To minimize the risk of electrocution, fire, or equip-
ment damage, installation work and electrical wir-
ing MUST be done by an electrician or qualified
service personnel.
Note About Extension Cords: Using an incor-
rectly sized extension cord may decrease the
life of electrical components on your machine.
Refer to Extension Cords on Page 14 for more
information.
Te s t Ru n
Once assembly is complete, test run the machine
to ensure it is properly connected to power and
safety components function properly.
The test run consists of the following: 1) The verti-
cal and horizontal spindle motors run correctly,
2) the E-STOP button and column interlock safety
features work correctly, and 3) the power feed unit
works correctly.
If you find an unusual problem during the test run,
immediately stop the machine, disconnect it from
power, and fix the problem BEFORE operating the
machine again. The Troubleshooting table in the
SERVICE section of this manual can help.
DO NOT start machine until all preceding
setup instructions have been performed.
Operating an improperly set up machine
may result in malfunction or unexpect-
ed results that can lead to serious injury,
death, or machine/property damage.
Serious injury or death can result from
using this machine BEFORE understanding
its controls and related safety information.
DO NOT operate, or allow others to operate,
machine until the information is understood.
Mill Test Run
1. Clear all setup tools away from machine.
2. Set horizontal spindle to 72 RPM (see Page
35 for details on how to change speeds).
Note: Make sure to close and tighten column
rear cover so interlock switch is set. Mill will
not run if this is not done.
