Resetting the spindle circuit breaker

The spindle circuit breaker located inside the control box. In case of spindle overload, such as during a tool crash, the spindle breaker will trip. If that happens follow the procedure below to reset the circuit breaker:

1. Shut down and unplug the machine.

Caution:

Avoid damage or personal injury!

Be ready to support the rear panel when removing the rear panel screws in the next step.

Do not allow the rear panel to drop onto the machine's cables.

2. Remove the rear panel of the machine by removing the eight thumb-screws securing the panel to the machine housing.

3. Locate the breaker labeled "Spindle" on the rear panel of the control box.

Note:

If the circuit has tripped, the switch will be in the "off" position - toward the machine. If the breaker switch is pointing away from the machine, it does not need to be reset.

4. If the breaker has tripped, move the switch back to the "on" position.

5. Replace the rear panel and secure it with the eight thumb-screws.
