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.	Fig. 18

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.
