Functional principle

2.1

Replacement of the threaded mandrel (Fig. 3)

• Remove the battery from the tool.
• Loosen lock nut C using a double open-ended spanner (WAF 24/27).
• Unscrew nosepiece B.
• Push back slide J as far as it will go.
• Unscrew threaded mandrel A.
• Align the appropriate threaded mandrel A with the hexagonal surface in slide J.
• Screw on a nosepiece B matching the thread size and secure with lock nut C.
2.2

Adjusting the threaded mandrel length "X"

• Loosen lock nut C.
• Adjust the threaded mandrel length "X" to the nut length by turning nosepiece B (Figure 4).
• Fully utilise the thread depth of closed blind rivet nuts (Figure 4).
• Hold nosepiece B with lock nut lock C using a double open-ended spanner (WAF 24/27)
to prevent it from turning.

Adjusting the setting force

The setting force to be set depends on the blind rivet nut size and blind rivet nut material, and
on the materials to be riveted (material, hole diameter, material thickness).
The setting force is adjusted as follows:
1. Select the setting value from the quick setting guide
2. Set the selected setting value on the display
3. Carry out a few setting trials and adjust the setting value, if necessary
1. Select the setting value from the quick setting guide
The appropriate numerical value can be selected in the quick setting guide, depending on the
blind rivet nut size and blind rivet nut material.
(e.g. M5 - steel 
