HVLP Gun Repair Tip. Repacking A Maxum Spray Gun.
What happens here
After cleaning the gun thoroughly with a solvent like lacquer thinner or acetone, drop the new Teflon packing into the appropriate slot. This often requires some dexterity, possibly using a pick to guide it, as the opening is small. Once the packing is seated, reattach the packing nut. It's important to only hand-tighten the packing nut initially to avoid damaging the new packing. After the packing nut is installed, insert the lubricated needle into the gun from the back, ensuring it slides in smoothly. Finally, reattach the nozzle assembly to the front of the gun.
Goal: Carefully insert the new Teflon packing into the designated slot, then reattach the packing nut, making sure not to overtighten it. Reassemble the rest of the gun components including the needle and nozzle.
