I see machines sold with pushbutton switches, paddle switches and safety switches that are not. A easy test is to turn on the machine and leave it running. Then flip the breaker off, wait five seconds and flip the breaker back on.
If the machine continues to run you do not have a safety switch with contactor or overloads to protect you or the motor. If the machine continues to coast to a stop you probably have some motor protection in the switchgear.
