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)

Fig. 20.

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.
