Test Run

Test run your machine to make sure it runs prop- erly and is ready for regular operation.

The test run consists of verifying the following: 1) The motor powers up and runs correctly, 2) the motor turns the correct direction (machine is not wired out of phase), and 3) the emergency stop button safety feature works correctly.

If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop using the machine immediately, then review Troubleshooting on Page 43.

If you still cannot remedy a problem, contact our Tech Support at (570) 546-9663 for assistance.

Before starting this machine, make sure you have read through the rest of the manual and are familiar with the various functions and safety features on this machine. Failure to follow this warning could result in serious personal injury or even death!

—When operating correctly, the machine runs smoothly with little or no vibration or rubbing noises.

—If the motor is running but the beam does not move, the power may be connected out of phase, and the motor will emit a loud, high-pitched whine. Stop the machine IMMEDIATELY, shut off the power source, then swap any two of the three power wires that connect to the motor (refer to Page 56). Repeat Steps 5–9.

—Investigate and correct strange or unusual noises or vibrations before operating the machine further. Always stop the machine and disconnect it from power before inves- tigating or correcting potential problems.
