  If your Echo Paint Sprayer isn't spraying, start by checking if the chemical line is completely clogged with dirt. If so, clean it. Also, make sure the chemical tank isn't empty; refill it if needed. If the pump is damaged, it is best to consult your Echo dealer.

  If the muffler is wet with fuel on your Echo Paint Sprayer, it's likely the fuel mixture is too rich. Try opening the choke. Additionally, clean or replace the air filter, and consider adjusting the carburetor. If problems persist, consult your Echo dealer.

  If your Echo Paint Sprayer has no mist discharge or poor mist discharge, it could be due to several factors: * The valve might be closed (or partially closed), so open it. * The valve could be clogged; clean it. * The nozzle may be clogged; clean it. * The pump case/blade might be worn out (resulting in low pressure), so replace it. * The chemical liquid line could be defective (mechanical seal or packing, etc.), so replace it. * A cracked spraying hose might be in use, so replace it. * The nozzle orifice chemical might be too large (releasing too much chemical), so replace it.
