How to adjust the setting force
The FireFox
is adjusted to a setting force suitable for the respective blind rivet nut size
®
(e.g. M6). This ensures that all blind rivet nuts of certain thread dimensions (e.g. M6) but with
differing nut lengths are always set precisely as intended into materials of varying thicknesses.
To adjust the setting force, follow the sequence of operations below:
1.
Press down completely green release button M.
2.
Adjust the setting stroke to maximum stroke of 10 mm (until the blue mark on the stroke
scale becomes visible!)
3.
The setting force can be pre-set using the enclosed colour code chart. The right colour
code can be selected on the colour code chart according to the nut sizes and the nut
materials (e.g. M6 – steel colour code red)
4.
Using the enclosed hexagon screw driver SW3, turn the set screw with colour scale G to
the selected colour code in the display window.
5.
Winding down the blind rivet nut to be set (see item 5.1). Insert the blind rivet nut into
the material to be riveted. For materials of varying thicknesses it is advisable to select
maximum material thickness.
6.
Trigger a setting sequence by pressing the activation button. Then check the nut you have
set:
•
If the nut is not sufficiently deformed during this process, use the hexagon screw driver
SW3 to screw in the set screw with colour scale F by c. 0.5 rotations. Then repeat the
setting sequence with a new nut and check once again.
•
If the nut becomes too deformed (e.g. difficult to remove; nut thread deformed), the
set screw F should be unscrewed about 1 rotation. Then repeat the setting sequence with
a new nut and check once again.
Turning in setscrew F increases the setting force of the rivet tool; unscrewing decreases
the setting force!

How to wind down a nut
•
Position blind rivet nut without tilting on threaded mandrel C.
•
Then use the blind rivet nut setting tool to press the threaded mandrel towards the blind
rivet tool. This action will automatically start the winding down process.
•
Do not press activation button!
•
Keep a tight hold of the blind rivet nut throughout the winding down process until the blind
rivet nut rests on nosepiece B. The winding down process finishes automatically.
