Remember to always refer to your sprayer’s user manual for specific disassembly and reassembly instructions. Never force components; gentle pressure is key to avoid damage.
Once all components are thoroughly cleaned and dried, reassemble the sprayer, ensuring all connections are secure and airtight. A final rinse with clean solvent and then a final flush with water (if applicable) will ensure any residual cleaning solvent is removed. Finally, store your sprayer in a dry, secure location, protecting it from dust and moisture.
