Grounding Requirements
This machine must be grounded! In the event
of certain types of malfunctions or breakdowns,
grounding provides a path of least resistance
for electric current in order to reduce the risk of
electric shock.
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without
yellow stripes) is the equipment-grounding wire.
If power cord repair or replacement is necessary,
do not connect the equipment-grounding wire to
a live (current carrying) terminal.
Check with a qualified electrician or service
personnel if you do not understand these
grounding requirements, or if you are in doubt
about whether the machine is properly grounded.
If you ever notice that a cord is damaged or
worn, disconnect it from power, and immediately
replace it with a new one.

service person ensure safe
power connection.
Unpacking
This item was carefully packaged to prevent
damage during transport. If you discover any
damage, please immediately call Customer
Service at (360) 734-1540 for advice. You may
need to file a freight claim, so save the containers
and all packing materials for possible inspection
by the carrier or its agent.
Inventory
This class of lathes is built specifically to order.
To verify that your shipment is complete, please
compare your order with the bill of materials
sheet from the crate.
Note:
Additional documentation pertaining to
the electrical system is shipped inside of the lathe
electrical cabinet.
IMPORTANT:
DO NOT use a static phase
converter to create 3-phase power—it can quickly
decrease the life of electrical components on this
machine. If you must use a phase converter, only
use a rotary phase converter.
When connected to a rotary phase converter,
power from the manufactured power
leg (sometimes called 'the wild wire' or
'manufactured leg') can fluctuate. Make sure that
when you connect the lathe to the phase converter
you connect the wild wire to the lathe input
lead L2, and that L1 and L3 incoming power
do not fluctuate. Fluctuation of power to the
transformer may cause magnetic switch chatter
and transformer damage and prevent the lathe
from starting correctly.
Phase Converter
As specified in the Circuit Requirements
section on the previous Page, this machine must
be hardwired to the power source, using a locking
switch (see Figure 12).
This machine must also be connected to a
grounded metal permanent wiring system; or to a
system with an equipment-grounding conductor.
Due to the complexity and high voltage involved,
this type of installation MUST be done by an
electrician or qualified service personnel.
