3.2 How to set threaded mandrel length “X”
• Detach locknut A, using double open-end spanner.
• Adjust threaded mandrel length “X”, according to nut length (see image 4) by turning nosepiece B.
• Make full use of depth of thread for closed blind rivet nuts (image 4).
• Secure nosepiece B using locknut A.
The FireFox
®
F is adjusted to a setting force suitable for the respective blind rivet nut size
(e.g. M5). This ensures that all blind rivet nuts of certain dimensions (e.g. M5) but with differing
nut lengths are always set precisely as intended into materials of varying thicknesses.
4. How to adjust the setting force
To adjust the setting force, follow the sequence of operations below:
1. 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. M5 – steel

colour code white)
2. Using the enclosed hexagon screw driver SW3, turn the set screw with colour scale I to the selected
colour code in the display window (G).
3. 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.
4. 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 with colour scale F should be unscrewed about 1 rotation. Then repeat the setting se-
quence with a new nut and check once again.
Turning in set screw F increases the setting force of the rivet tool; unscrewing decreases
the setting force!
5. Sequence of operations
• 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.
