With the tool disconnected from the air line, adjust the pull-up stud
extension from the anvil face by loosening the anvil lock-nut. Thread a
rivet nut onto the pull-up stud
and allow approximately one (1) thread
of the pull-up stud to extend beyond the end of the insert. (When
setting up on a closed end part, bottom the pull-up stud in the fastener
and back off one turn). Snug the anvil face against the head of the
fastener and tighten the anvil lock-nut to maintain this setting.
Unthread the insert from the pull-up stud.
Now, connect the
air line to the tool. When you hold the rivet nut threads against the
pull-up stud, it will automatically thread into the insert until the
fastener head seats securely against the anvil face.
Make sure that the
stroke adjustment ring is set to provide minimum pull-up. Actuate position 2
of the trigger (Fig. 1) and observe the pull-up stroke of the tool.
Notice that the pull-up stud is pulled into the front housing of the
tool, with no rotation of the stud.
The tool will
stall when it meets the pre-adjusted internal stop. Actuation of
position 1 of the trigger (Fig. 1), provides reverse rotation of the
stud, and disengages the stud from the installed fastener. Now you are ready
to set the stroke of the tool. You must provide the proper pull-up of
the fastener, to ensure proper installations.
Use the special
spanner wrench that is proved, to engage the holes in the stroke
adjusting ring (Fig. 1, G). Turning the ring in a counter clockwise
direction increases the stroke. Turning the ring in a clockwise
direction reduces the stroke. To determine the
amount of pull-up required, ensure the overall length of the fastener,
as shown in (Fig. 4). Refer to the pull-up factor chart (Fig. 5) and
select the thread size of the fastener to be installed.

Each fastener is
designed to perform in a specific grip range.
- Determine
the recommended maximum grip of the fastener (refer
to the fastener brochure, or see the data provided
on the fastener box).
- Measure
the material thickness in which you will be
installing the fastener.
- Subtract
the measured thickness from the published max. grip
of your fastener.
- Add
the difference calculated in Step 3, to the
applicable pull-up factor in the chart.
- Use
the fastener whose over-all length you have
measured, and run it through a tool cycle. Then
measure the over-all length after you have pulled
it.
-
Compare
the results with the calculated shortening req'd, as
determined in step 4 above.
To
increase pull-up with the AE 40 Tool, turn the
stroke adjustment ring counter clockwise. To
decrease the pull-up, turn the stroke adjustment
ring clockwise. Slight differences of (+.005) may
not require further adjustments.
Install
several fasteners in sample material, the same as
the grip you will be using, to ensure that all
settings are adequate.

Loosen the anvil lock-nut, and remove the anvil from the nosepiece (Fig.
6).
As shown in Fig.
7, use the pin supplied with the tool and engage the roll pin through
the pin insertion hole. Apply a light backpressure on the pin to
disengage the hex driver from the pull-stud
unscrew the pull-up stud
and remove it.
Select the pull-up
stud thread size that you need, and thread it into the pull-up stud
connector. Pull back on the pin to pull the hex driver out of the
way
thread the stud into connector until you feel it touching the hex
driver.
Rotate the stud
and driver slightly, to align the hex socket with the driver, and let
the hex driver snap into place, by slowly releasing the backpressure on
the pin.
Install the proper
anvil and the anvil lock-nut, and you are ready to proceed.
