NOTE: It is important to ensure that the face of the
micrometer is firmly against the Puller Head, and
the micrometer depth pin is in contact with the
Actuator Rod when measuring.
1. Check to see where the Limit Switch is set using
the Light Box and the Depth Micrometer.
2. Using an Allen wrench, remove Screw (Item 24,
Figure 5).
3. To increase the switch setting turn the Set Screw
(Item 17d, figure 6) counterclockwise; to decrease
it, turn it clockwise.
4. Adjust the switch to the specification of .430-.435”.
You will notice the Light Box light will come on
once the switch has been made.
5. Replace Screw (24).
NOTE: After tightening the Lockdown Screw,
verify the adjustment again by measuring with
the depth micrometer.
6. Once adjusted to the desired specification, discon-
nect the Light Box and reconnect the system. The
tool is now ready to drive fasteners.
