Now practice using the feed handwheel for over-
travel status. Rotate the feed handwheel until the over-
travel switch is engaged causing the 800 brake lathe to
shut down. Observe that the OVERTRAVEL light status
is now red on the control box.

Using the feed handwheel move the overtravel
actuator off of the overtravel switch about 1/2-inch and
turn the lathe back on.
5.6
Engage the feed engagement knob (gray) and
observe the auto feed operation. Allow the machine to
feed out until the overtravel switch is activated. The 800
brake lathe will shut down and the OVERTRAVEL status
light will light red indicating the cause.

Note that each time the feed engagement knob
(gray) is engaged, the FEED ENGAGED light is activated
and will light green.

LOCKED feature.

Make sure the feed engagement knob (gray) is
disengaged or pulled out toward the feed handwheel.

Lock the runout adjustment head using the lock
pin (yellow). It may be necessary to rotate the runout
adjustment head, using the motor handwheel, to
engage the lock.

Turn the power ON and observe the control box
status lights.
5.12
Engage the feed engagement knob (gray).
Observe that the 800 brake lathe will shut down and the
HEAD LOCKED status light will light red indicating the
cause. This is to prevent the operator from adjusting the
lathe when the cut begins.

Now disengage the feed engagement knob
(gray) and restart the lathe with the head locked.
Observe the time. After four and a half minutes the 800
brake lathe will shut down. This feature is a time out if
the lathe is left unattended and the feed engage is not
in gear to shut down the machine.
