STARTING AND STOPPING THE
TOOL
The switch (A) Fig. 18 provides electrical power to the
adjustable speed drive. Lift the safety cover (B), and move
the switch to the “up” position. To turn the power off, simply
push the safety cover (B) down. NOTE: In case of emer-
gency, immediately push the safety cover (B) down to
shut off power.
These machines have a circuit that automat-
ically decelerates the spindle once the stop
button (C) Fig. 22 on the control panel is
pushed. Although an optional dynamic
brake is mentioned in the manual provided
with the Baldor Adjustable Speed Controller,
Delta does not recommend the use of any
optional brake systems on the lathe. Further,
DO NOT CHANGE OR ADJUST the con
-
troller settings that have been pre-set at the
factory.
Fig. 18 shows the switch with safety cover down in the
“OFF” position.Fig. 19 shows the lathe in the “ON” position
(switch cover (A) up and switch (B) up.
LOCKING SWITCH IN THE
“OFF” POSITION
IMPORTANT: When the tool is not in use, the switch should
be locked in the “OFF” position (A) Fig. 20 to prevent unau-
thorized use, using a padlock (B) Fig. 20, with a 3/16” diam-
eter shackle inserted through the holes in the switch plate (C)

ACTIVATING THE SPINDLE
Even though power may be going to the adjustable speed
drive, the spindle will not turn until the operator activates it.
1. Before activating the spindle, be certain that all clamps,
bolts, etc. are tight and clear. Turn the workpiece by hand to
see that it clears the tool rest and to make sure that the spin-
dle lock is in the UNLOCKED position (A) Fig. 21.
2. Prior to activating spindle, be certain that the speed
control knob (A) Fig. 22 is set to the “zero” position.
Do not change input voltages. This action
will cause severe damage to the inverter.
3. After turning power switch on, push the “forward” (FWD)
button (B) Fig. 22. Then slowly turn the knob (A) clockwise to
the desired speed.
4. To stop spindle without turning the power off, press the
stop button (C) Fig. 22 on the control panel.
5. To restart, press the FWD button (B). The spindle will
gradually return to the speed at which it was stopped.
