ULL FORCE REGULATION
Install the proper head set 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.
Using a 3 mm allen key, unscrew the force adjustment screw (3) out
until it stops. You will see the white line when looking inside the
window on the top of the black cover. When
pulling the trigger the tool should not pull back as
this is at minimum force.
Thread an insert/rivet nut on to the mandrel (2) 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 (2) until it
comes in contact with the anvil. To adjust the force, start by turning
the force adjustment screw in a ¼ turn and try to set the rivet nut.
Continue turning the screw a ¼ turn after each setting attempt until there is deformation of the rivet
nut. Continue to adjust the force until the rivet nut fully installs. For second grip parts and larger, you
may need to test in material thickness to achieve a proper installation.
Test the tool set up by installing rivet nuts into the representative material thickness to be used in the
application and increase the force if needed.
If during the set up process the tool does not automatically reverse out of the rivet nut press the
manual reverse button (4).
If you will be installing rivet nuts into different material thicknesses, test the rivet nut in the thickest
material location. This position will require the most installation force.

•
Head Set assembled, tool connected to air supply, force adjustment complete.
•
Screw the rivet nut onto the mandrel (2) 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 anvil.
•
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.
