      If the pumping action on your Stihl Lawn and Garden Equipment isn't producing any pressure, it could be due to a few reasons. First, check if the pump isn't tightened down properly; if so, lock the pump handle and tighten it down. Alternatively, the O-ring on the pump or the piston cup seal might be damaged. In these cases, install a new O-ring or a new piston cup seal, respectively.

      If the pumping action on your Stihl Paint Sprayer isn't producing any pressure, there could be a few reasons. First, the pump might not be tightened down properly; lock the pump handle and tighten it securely. Alternatively, the O-ring on the pump could be damaged, in which case you should install a new O-ring. Finally, the piston cup seal might be damaged, so you may need to install a new piston cup seal.

      Jason MorrisSep 7, 2025
      If the pumping action of your Stihl Paint Sprayer isn't building any pressure, it could be due to a few reasons. First, make sure the pump is properly tightened down by locking the handle and tightening it. If that doesn't work, the O-ring on the pump may be damaged, requiring a replacement. Alternatively, the piston cup seal might be damaged, which would also need replacing.
