supply to ensure it is between 6 and 7 bar.
Tool capacity does not match the
type or diameter of the rivet.
Use another riveter from the BNT range with a
higher power rating.

rivet used, causing an incorrect
opening of the jaws, in turn
hindering suction of the shaft.
Identify the appropriate nozzle for the task and
replace it following the corresponding procedu-
re described in the manual.
The spent mandrel collector is full –
preventing the collection of more.
Empty the spent mandrel collector.
