Drill Nut Riveter for Sizes M3, M4, M5 & M6

Operation Guide

• WARNING: The objects to be riveted MUST BE SECURELY FIXED BEFORE nut riveting in order to avoid possible injury. Unsecured objects may rotate with the driving tool if not clamped

• IMPORTANT: Ensure the threads on mandrel are clean and the loaded rivet nut has full threads engagement with threaded mandrel at riveting. It is strongly recommended cleaning and lubricating the threads on mandrels before and after use

• CRITICAL: Before Actual Nut Riveting, it is REQUIRED to do Air Riveting(s) to determine the Working Torque for the driving tool and for the selected rivet nut size/type

1. Tool Installation:
Change the sized nose piece and paired threaded mandrel for the selected rivet nut if the installed pair does not match. Firmly tighten the threaded mandrel with the plunger tube with wrench kit, check and confirm the other components are tightly fixed in position; insert the hex shank into driving tool chuck. Tighten firmly and switch driving tool to low speed mode.

2. Air Riveting:
2.1 Hold the adapter, pull the trigger on driving tool to push the threaded mandrel forward until the adapter emits a click sound
2.2 Release the trigger and reverse the direction of the driving tool
2.3 Manually load the selected rivet nut onto threaded mandrel; or align the nut with mandrel by one hand and use another hand to pull the trigger slightly to have the nut loaded by driving tool
2.4 Make sure no screw jam or stuck screw occur
2.5 Make sure there is some clearance between nose piece and the flange of rivet nut but keep full threads engagement for the nut
2.6 Adjust the torque setting from low to high until ideal rivet is made and ensure no screw stripping occurs. The torque setting of the test rivet is the Working Torque for the driving tool and for the selected rivet nut size and type
2.7 Reverse direction of the driving tool hold the adapter and trigger to make nut flange leave from nose piece, then grip the nut and trigger again to release the waste nut from mandrel or screw the nut off from the mandrel manually
Tip 1: If torque setting is higher than the Working Torque for the selected nut, thread stripping will occur. The thread stripping means the Working Torque is lower than current torque setting. Clean and lubricate the threads on mandrel, decrease the torque and repeat Air Riveting operations until ideal riveted nut is made. It is recommended recording the Working Torque for future use. Insure the nut rivet screws on smoothly onto the mandrel

3. Actual Nut Riveting:
3.1 Hold the adapter, pull the trigger on driving tool to send the threaded mandrel forward until the adapter emits a clicky sound
3.2 Release the trigger and reverse the direction of the driving tool
3.3 Manually load the selected rivet nut onto threaded mandrel; or align the center hole of the rivet nut with mandrel by one hand and use another hand to pull the trigger slightly to have the nut loaded by driving tool
3.4 Make sure no screw jam or stuck screw occurs
3.5 Make sure the rivet nut is not tightened with the threaded mandrel but the rivet nut keeps full threads engagement with mandrel
3.6 Check and confirm the objects to be riveted have been SECURELY FIXED
3.7 Pull the trigger on driving tool to withdraw the threaded mandrel until the nut flange slightly contacts nose piece
3.8 Release the trigger, insert the rivet nut into drilled hole until rivet flange gets stopped by the object to be riveted; position the adapter aligned with hole center
3.9 Grip the adapter firmly then pull the trigger on the driving tool until completion of riveting
3.10 Reverse direction of the driving tool, pull the trigger on the driving tool to release the nose piece from riveted nut and then release the adapter to release the threaded mandrel from riveted nut, or release the threaded mandrel manually after the nose piece gets released from riveted nut
Tip 1: If during Actual Nut Riveting the torque setting is lower than required, the driving tool will give an alarm sound. Increase the working torque to resume the work but must ensure thread stripping will not occur at the increased torque setting
Tip 2: Use low RPM for better control of riveting quality
Tip 3: Make sure the threads on mandrel are clean before riveting

IV. Maintenance
1. The nut riveting adapter is lubricated before shipping. Recommend cleaning the components of plunger tube, and using lubricant grease to re-lubricate its parts regularly according to use
2. Threaded mandrel replacement:
Life span of threaded mandrel varies with usage frequency and the uses of different rivet nut sizes/types. Recommend replacing the threaded mandrel with new spare (Part No. ARNA10-M3, ARNA10-M4, ARNA10-M5, ARNA10-M6) before worn-out.
