8.Listen for abnormal noises and watch for unexpected actions from the mill. The machine should run smoothly and without excessive vibration or rubbing noises.

—Strange or unusual noises or actions must be investigated immediately. Press the emergency STOP button to turn the machine OFF and disconnect it from the power source before investigating or correcting potential problems.

9.Press the emergency STOP button to turn the machine OFF, then wait for the spindle to stop on its own.

10.WITHOUT resetting the emergency STOP button, press the ON button. The machine should not start.

—If the machine does not start, the emergency STOP button safety feature is working correctly.

—If the machine does start (with the emergency STOP button pushed in), immediately disconnect power to the machine. The emergency STOP button safety feature is not working correctly. This safety feature must work properly before proceeding with regular operations. Call Tech Support for help.

11.Press the OFF button, then turn the spindle direction switch to the off (middle) position to prevent the spindle from starting when you next use the ON button.

The mill comes with a power feed unit for X-axis table travel. Proper operation of the limit switch attached to the front middle of the table is critical for the safe use of this power feed unit. If the power feed does not operate as expected during the following steps, disconnect it from power and contact our Tech Support at (360) 734- 1540 for assistance.

To test the X-axis power feed unit and table limit switch:

1.Make sure all tools, cables, and other items are well clear of table movement as you follow these steps.

2.Refer to the Table Movement section, beginning on Page 29, to understand how the power feed, table locks, and limit switch function.

3.Loosen the table locks on the front of the table.

4.Plug the power feed power cord into a 110V power outlet.

Note: There are 110V outlets on the right side of the electrical cabinet that can be used for the power feed or other 110V accessories.

5.Make sure the power feed directional lever is in the neutral (middle) position, turn the speed dial counterclockwise to the lowest setting, then flip the power switch to the on (up) position.

6.Turn the directional lever to the left, slowly turn the speed dial clockwise to increase the speed, then confirm that the table is moving to the left.

7.Watch for the table limit stop to hit the limit switch and turn the power feed OFF, stopping the table movement.

8.Turn the directional lever through the neutral (middle) position and all the way to the right. The table should begin moving to the right.

9.Confirm that the table stops moving when the limit stop presses against the limit switch plunger.

10.Move the directional lever to the neutral (middle) position and flip the power switch to the off (down) position.

Congratulations! The Test Run of the mill is complete. Continue with the next page to perform the Spindle Break-Inand Adjustments & Inspections procedures.
