in addition to the reservoirs, we also recommend
that you lubricate all other points on the machine
at this time. this can be accomplished by follow-
ing the maintenance schedule on Page 64.
Note: If this lathe was shipped with oil in the res-
ervoirs, do not change that oil until after the test
run and spindle break-in procedures.
Adding Coolant
add the coolant of your choice now. For detailed
instructions on where the coolant tank is located
and how to add fluid, refer to Coolant System
Service on Page 70.
Power Connection
before the machine can be connected to the
power source, an electrical circuit must be made
available that meets the minimum specifications
given in Circuit Requirements for 220v on Page
15. if a power circuit has not been prepared for the
machine, do that now.
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 16 for more infor-
mation.
Note About 3-Phase Power: Due to the startup
load from this machine, we do not recommend
using a static phase converter to create 3-phase
power—as 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 and connect the manufactured
leg or "wild wire" to the S terminal (see location in
Figures 22–23). The S terminal can handle power
fluctuation because it is wired directly to the motor.
To connect the power cord to the lathe:
1. press the stop button, turn the two-speed
motor switch to the oFF position then open
the electrical cabinet door.
2. identify the r, s, and t terminals and the
grounding terminal (see figure 22).
figure 23. ground and hot wires connected.
3. thread the power cord through the strain
relief shown in figure 22.
4. Connect the incoming hot wires and ground
wire to the terminals shown in figure 23.

Electrocution or fire
may occur if machine is
ungrounded, incorrectly
connected to power, or
connected to an undersized
circuit. use an electrician
or a qualified service
personnel to ensure a safe
power connection.
