Functional principle
2.1
Replacement of the threaded mandrel (Fig. 3)
•
Remove the battery from the tool.
•
Loosen lock nut C using a double open-ended spanner (WAF 24/27).
•
Unscrew nosepiece B.
•
Push back slide J as far as it will go.
•
Unscrew threaded mandrel A.
•
Align the appropriate threaded mandrel A with the hexagonal surface in slide J.
•
Screw on a nosepiece B matching the thread size and secure with lock nut C.
2.2
Adjusting the threaded mandrel length "X"
•
Loosen lock nut C.
•
Adjust the threaded mandrel length "X" to the nut length by turning nosepiece B (Figure
4).
•
Fully utilise the thread depth of closed blind rivet nuts (Figure 4).
•
Hold nosepiece B with lock nut lock C using a double open-ended spanner (WAF 24/27)
to prevent it from turning.
2.3
Adjusting the setting stroke "Y"
The FireBird
Pro S GE is adjusted to a setting stroke suitable for the respective blind rivet nut
®
size (e.g. M5x11.5) and material thickness. The setting stroke corresponds to the distance the
threaded mandrel is drawn into the nosepiece during the setting process and thus how far the
blind rivet nut is compressed.
IMPORTANT! Unlike for the FireBird
must be readjusted if the nut length or material thickness is changed.
The setting stroke "Y" is adjusted as follows (Figure 2):
1. Loosen the setting sleeve (D) with the double-ended open-jawed wrench (WAF 24/27)
provided.
2. Adjust the setting stroke "Y" with reference to the stroke scale (F) by turning the setting nut
(E). (One line on the stroke scale / one full turn of the setting nut corresponds to 1 mm setting
stroke)
Adjusting the setting nut towards the tool reduces the setting stroke; adjusting it away from
the tool increases the setting stroke.
