STARTING AND STOPPING THE LATHE
The power switch, located under the red switch cover (B)
Fig. 18 controls the electrical power to the machine. Lift the
switch cover (B) and move the switch up to the "ON" posi-
tion. To turn the power off, push the switch cover (B) down.
Fig. 18 shows the switch with switch cover down in the
"OFF" position. Fig. 19 shows the lathe in the "ON" position
(switch cover(A) up and power switch (B) up).
When the machine is turned off using the
stop button (A) Fig 18A, the spindle will decelerate under
power.
When the machine is turned off using the
switch cover (A) Fig 19, the spindle will free spin until it
stops.
Always use switch cover to PREVENT
entanglement in rotating parts.
DELTA DOES NOT RECOMMEND the use
of any optional brake systems on the lathe. Further, DO
NOT CHANGE OR ADJUST the controller settings that
have been pre-set at the factory.
LOCKING THE SWITCH IN THE "OFF" POSITION
IMPORTANT: When the machine is not in use, the switch
should be locked in the "OFF" position to prevent unauthor-
ized use, using a padlock (A) Fig. 20 with a 3/16" diameter
shackle inserted through the holes in the switch plate (C)
Fig. 19.
ACTIVATING THE SPINDLE
Even though power may be going to the adjustable speed
drive, the spindle will not turn until you activate it.
1. Before activating the spindle, tighten and clear all
clamps, bolts, etc. Turn the workpiece by hand to see
that it clears the tool rest and to make sure that the
spindle lock is in the UNLOCKED position (A) Fig. 21.
2. Prior to activating the spindle, set the speed control
knob (A) Fig. 22 to the "zero" position.
Input voltage must be 200 to 240 single phase.
Other voltages will severely damage the inverter.
3. After turning the power switch on, push the "run" button
(B) Fig. 22. Then slowly turn the knob (A) clockwise to
the desired speed.
NOTE: The numbers in the display multiplied by 10 will indi-
cate the spindle speed.
