THE RIGHT WAY! Repacking Your Airless Spraygun
What happens here
The new front end of the gun is threaded back onto the main body. The trigger must be pulled back during this step to prevent the needle from scoring when it contacts the seat inside the gun. Once the front end is secured, the new filter is inserted. Finally, TSL (Throat Seal Liquid) is applied to all threads and inside the needle assembly for lubrication. The needle is worked a few times by squeezing the trigger to distribute the lubricant, ensuring smooth operation and preventing sticking.
Goal: Reattach the front end, install the new filter, and lubricate all moving parts for smooth operation.
