Carlisle DeVILBISS SLG-650 Bedienungsanleitung Seite 10

Before using this spray gun, the packing nut should be adjusted as follows;
1 Tighten packing nut until fluid needle starts to bind in the packing.
2 Loosen packing nut just enough so the fluid needle moves freely.
The packing nut is intentionally left loose so the PTFE packing does not take a "set" before the spray
gun is used.
This allows full utilisation of the packing.
