FORCE ADJUSTMENT
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.
Using a 3 mm allen key, unscrew the force adjustment screw (3) out
until it stops. 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 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
anvil.
Take the force adjustment tool (2) that is provided, and place it into the
force adjustment screw (3). Attempt to set the rivet nut insert by
depressing the trigger fully and holding it until the tool has reversed out.
To adjust the force, turn the force adjustment tool (2) a ½ turn in
(clockwise) to increase the force or ½ turn out (counter clockwise) to
decrease the force. Continue turning the tool a ½ 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 in to the representative
material thickness to be used in the application and increase the force if
needed.
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.
If during the set up process the tool does not automatically reverse out
of the rivet nut press the manual reverse button (4).
Should the mandrel bind in the application (manual reverse button will
not work), use the included tool (5) to reverse the mandrel from the
insert.
