Air supply
All tools are operated with compressed air at an optimum pressure of 6 bar (max. 7 bar).

on the main air supply. Air hoses should be oil resistant, have an abrasion resistant
exterior and should be armoured where operating conditions may result in hoses being
damaged. All air hoses shall have a minimum bore diameter of 6.4 millimetres or 1/4
inch.
Stroke adjustment
This adjustment is required to achieve optimum deformation of the rivet nuts. The tool is
factory set to a stroke of 3 mm. Turn the Adjusting Ring (9) to the left to reduce it, to the
right to extend the stroke length. Each stroke step changes the stroke length by 0.1 mm.
To determine the correct stroke, it is recommended to place some blind rivet nuts in a
test plate with the same sheet thickness and hole diameter as the original sheet.

large a stroke is set, there is a risk that the mandrel tears off or the thread of the blind
rivet nut is damaged during the setting process.
For guide values for the stroke adjustment, refer to the instructions of the blind rivet nut
manufacturer.
