Just another thought, read thisd on another forum, for ALL A4 user to properly check that their SENSI is functioning properly.
Fill the loader about half way, put he marker in SENSI 1, then calibrate the SENSI. Once that paint runs out, you don't have to let it rip like ad to do this, if functioning properly, and with SENSI turned on and CALIBRATED correctly, then the marker should only allow about one shot per second.
This way you'll know for sure that the marker is performing as it should and it's not just the HALO.
If SENSI is working and the marker is in SENSI 1, then there should be absolutely NO CHOPPING WHATSOEVER........ period.....
I can't understand how all these people can be blaming the HALO, or any other loader come to mention it, if they have a correctly callibrated and functioning SENSI.
My understanding of the SENSI, according to the manual, is that even if you were to use a non-morised loader, like the old pluming pipe versions about 10-15 years ago, then there should still be no chopping issues.......
