Operation and Usage Tips

Do not disassemble motors; a significant reduction in motor performance will occur.

Do not machine shafts; this will have a negative effect on shaft run out and perpendicularity

Do not disconnect motor from drive while in operating

Do not use holding torque/ detent torque of motor as a fail safe brake

Do not hold motor by lead wires.

Failure to comply with these recommendations will void all warranty terms.
