2-2 Electrical Equipment
1.
The electrical cabinet is also equipped with overload circuit breakers and electric
magnetic contactors to protect motors from overload during excess heavy cutting.

The foot brake is connected with micro switch. Stepping the footbrake is quicker
to stop the lathe than turning off the main power switch. The spindle can only
rotate again by resetting and operating the spindle operation control lever after
releasing the foot brake.

The spindle will rotate continuously as long as the jog button on the top of the
electrical control panel is pressed.
