Why does my Vaper 19220 Paint Sprayer have a jerky or fluttering pattern?

If your Vaper Paint Sprayer exhibits a jerky or fluttering pattern, it might be due to a loose or damaged fluid tip/seat, so tighten or replace it. Other causes might be that the material level is too low (refill), the container is tipped too far (hold it more upright), there is an obstruction in the fluid passage (back flush with solvent), the fluid tube or fluid inlet nipple is loose or broken (tighten or replace it), or the fluid needle packing nut is dry or loose (lubricate or tighten it).
