RETRACTION SAFETY LOCK
This machine is equipped with a special retracting lock assembly that will prevent the
operator from accidentally engaging the retracting mechanism.
The above diagram is for reference only, and the operation will be very easily followed
when you check it out on the machine. If the stop rod is set to disengage the feed and
stop the rotation of the boring head after it clears the bottom end of the cylinder being
bored, it will spring load the retracting mechanism so the bar will automatically retract
from the cylinder when the Retraction Release Plunger is pressed.
If you wish to retract the bar at any time, when it has not been disengaged by the stop
rod, it will be necessary for you to press the retration release plunger and pull forward on
the feed lever.
The Retraction Release Plunger is merely a locking mechanism which will allow the bar
to come into neutral, but not go into retraction.
