Manual unscrewing of the blind rivet nut

Manual unscrewing of a blind rivet nut may be necessary if:
• The blind rivet nut was not screwed on straight before the setting operation, or the thread
of the blind rivet nut or threaded mandrel 1 is defective;
• The thread is deformed after the setting operation and the tool does not unscrew automa-
tically (selected setting stroke too high, wrong setting!) and cuts out due to overloading.
Æ Remove the battery. Then unscrew the threaded mandrel by hand. To do this, insert
the hexagon screwdriver WAF 4 into the hexagon socket of the tool (see Figure 5),
possibly after removing the accessory magazine (Figure 5), if necessary. Carefully loosen
threaded mandrel A by screwing in anti-clockwise direction. After unscrewing the defor-
med nut, insert the battery into the tool again and remove the hexagon screwdriver. Press
and release switch I to bring the tool back to Home position in a slow reference run.
Important: Set the correct setting stroke as described in 2.3.

Setting a blind rivet nut

• Insert the correctly fitted nut into the hole of the workpiece as far as it will go using the
blind rivet nut setting tool.
• Start the setting operation by pressing switch I. The setting operation runs until the set
setting stroke is reached before the set blind rivet nut is unscrewed again automatically.
