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 auto-
matically (setting force selected too high, wrong setting!) and cuts out due to overloading.
This is signalled as error message "E3" on the display and by rapid flashing of the light
ring.
 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 threa-
ded mandrel A by screwing in anti-clockwise direction. After unscrewing the deformed
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. The last
numerical value set is shown on the display. Caution: Set the correct (lower!) numerical
value as described in section 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 set-
ting force is reached before the set blind rivet nut is unscrewed again automatically.
• Important!
Incorrect setting operation: Error message E1
If the set numerical value is not reached during the setting operation, the setting operation
stops, the tool unscrews the nut and automatically returns to Home position. Error
message "E1" appears on the display G. The error is additionally signalled by rapid flashing
of the light ring H and rapid beeps. Acknowledge the error by pressing the S button (> 1
sec). Only then can the tool be used again. rS (reSet) is shown on the display G. In this
mode, the incorrectly set blind rivet nut can be reset at reduced speed. To do this, screw
on the nut already set again (see section 2.5) and press switch I again. After one rS setting
operation, the last numerical value set appears on the display G again. If the blind rivet nut
is not reset, quit rS mode by pressing the S button (>1 sec).
• Important!
Resetting of one or more blind rivet nuts: If one or more blind rivet nuts have been set with
a numerical value that is too low, it is possible to reset these blind rivet nuts in rr mode
(reWork). To do this, select the correct numerical value for the setting force (see section
2.3). Then hold the S button pressed until the program memory P0 - P9 has been skipped
and rr appears on the display G. All incorrectly set nuts can then be reset with the corrected
numerical value. Press the S button again to bring the tool back to normal mode.
