Tool Storage

The cabinet shelf contains a perforated cushion for the accessories, as shown in Figure 20.

Operating Controls

The magnetic starter with control buttons is mounted to the motor. Press the “start” button to begin rotation of the auger. Press the “stop” button to stop rotation of the auger. The auger will quickly coast to a stop after the “stop” button is pressed.

The magnetic starter is a valuable safety feature of the Mortiser. Should electrical power suddenly be cut off while the mortiser is being operated, the magnetic starter will prevent the machine from immediately re-starting when power is restored. To re-start the Mortiser you must press the “on” button.
