Determine the proper stroke distance of the tool based on the size
and style of rivet nut insert you are using for your application material
thickness. Contact Sherex should you require assistance determining
the appropriate stroke.
Warning**
A stroke setting that is too large
for the application may cause an over installed installation condition
which may damage the mandrel, the base material, and/or the rivet
nut insert.
Stroke Adjustment (3)
Install the proper nose assembly for the rivet nut thread size that you
will be using. Attach an air supply to the Air Inlet (1) per the
recommendations in this manual.
To adjust the stroke distance of the tool, use the key provided with
the tool and place it in the stroke adjustment ring (3) located in the cut
out of the back cover. The ring, when threaded fully in, will pull to 1
mm (0.040”) of stroke. Turning the key counter-clockwise from one side of the window to the other
will increase the stroke approximately .12 mm (.005). Continue to adjust the ring out until you have
approximated the stroke distance required. Test by installing a rivet nut and measuring the collapsed
distance of the part. Adjust the ring as required to achieve the desired installation distance.
Note**
Threading the adjustment ring beyond the 6 mm stroke may cause the auto-reverse to not
function. If this occurs, turn the adjustment ring in the opposite direction reducing the stroke distance
to 6 mm.
Manual Reverse
Button (4)
Air Inlet (1)
Thread an insert/rivet nut on to the tool 1 or 2 turns. Apply pressure to the insert and the auto-spin on
feature will engage thereby spinning the rivet nut up the mandrel until it comes in contact with the
nose piece.
If during the set up process the tool does not automatically reverse out of the rivet nut press the
manual reverse button (4).

•
Nose kit assembled, tool connected to air supply, force adjustment complete.
•
Screw the rivet nut onto the mandrel a couple turns, then a light pressure on it will start the
spinning of the mandrel (push to spin) and automatically stop when the rivet nut comes in
contact with the nose piece.
•
Insert fastener into the application.
•
Depress the trigger fully. This will place the insert and automatically reverse the tool out of the
installed rivet nut. (Depress the trigger and hold until auto-reverse engages). If auto-reverse
does not engage and insert has not collapsed, apply a manual pushing force to engage the
auto spin-on, and then depress the trigger. (Ensure the air pressure is within the specified
range).
•
If, at any time, manual-reverse (4) needs to be engaged, depress the button at the base of the
handle, to the right of the air inlet.
IMPORTANT
Do not push the mandrel without a rivet nut as this will cause the
mandrel to spin automatically. Ensure pressure settings are correct.
