Remove the gun from the hose and clean it. * The pump hose may be worn out. Replace the hose; it's recommended to do this annually. * The pump might be cold. Move the pump to a warm room to allow it to warm up, or run hot water through the sprayer. * The material flow might be turned down. Turn up the material flow control.
