Screwing On The Blind Rivet Nut - Gesipa FireBird Pro S GE Manual De Instrucciones

3. Hold the setting nut (E) with a double-ended open-jawed wrench (WAF 27/30) and tighten
the setting sleeve (D) hand tight with another double-ended open-jawed wrench (WAF 24/27).
The values for the setting stroke in the following table are purely guide values and depend
greatly on the blind rivet nut used and the material thickness. The required setting stroke must
be determined by trials with the exact material thickness. The greater the material thickness,
the smaller the setting stroke needs to be.
A new nut must be used for each attempt!

IMPORTANT! If the setting stroke is unknown, first set a lower setting stroke to prevent da-
mage to the thread. If the nut is not sufficiently set, increase the setting stroke in small steps
(max. 0.5 mm: half a turn of the setting nut). If too large a setting stroke has been set, and the
thread on the blind rivet nut has been damaged, it must be manually removed (see section
2.6).
*Guide values established with GESIPA
range of 0.25–3 mm in 1 mm material thickness.

Screwing on the blind rivet nut

• Place the blind rivet nut onto threaded mandrel A straight.
• We recommend that the blind rivet nut is screwed on by hand by approx. ½ turn to simp-
lify threading in of threaded mandrel A.
• Start the screw-on sequence by pressing switch I.
• Hold switch I pressed until the screw-on sequence stops automatically. While doing this,
hold the blind rivet nut secure to prevent twisting during the entire screw-on sequence.
The blind rivet nut must be correctly positioned on nosepiece B after the screw-on se-
quence. Otherwise, correct the setting of the threaded mandrel length (see Section 2.2).
Caution: If the switch is released prematurely, the nut will be unscrewed again!
