blind rivet nut size (e.g. M5). This ensures that all blind rivet nuts of certain dimensions (e.g.
M5) but with differing nut lengths (e.g. M5 x 11.5 and M5 x 13.5) can always be set precisely
as intended into materials of varying thicknesses.
The setting force is adjusted as follows:
1. The setting force value is selected using the setting-force chart included.
Excerpt from the setting-force chart:

steel
The right numerical value can be selected on the setting-force chart according to the nut sizes
and the nut materials. (e.g. M5 – steel > value for setting force 55)
2. After loosening locking screw 5 and removing cover 6, the value derived from the setting-
force chart is indicated on the riveting tool display 7 by pressing the plus/minus buttons. Pres-
sing the plus button will increase the numerical value. Pressing the minus button will reduce
the numerical value. If a button is held down for longer than one second, the numerical value
is modified in increments of 10.
