7. Maintenance
Proper maintenance ensures the longevity and performance of your paint sprayer:
- Cleaning the Nozzle: The nozzle can be cleaned using a needle and wet wipes. Do not use water to clean the nozzle, as this can damage internal components.
- Cleaning the Sprayer Body: Wipe the handle housing and exterior of the sprayer with a cloth. Do not soak the handle housing in water.
- Preventing Paint Drying: If the paint sprayer sits unused for more than 15 minutes, paint may dry on the nozzle and pump assembly. To prevent this, remove the spray bottle, secure its lid, shake it for 1 minute to stir the paint thoroughly, and then reinstall it on the spray gun to spray.
- Nozzle Replacement: If a disposable nozzle becomes clogged and cannot be cleaned, replace it with a new one.

8. Troubleshooting
If you encounter issues with your Saker Cordless Paint Sprayer, consider the following:
- Clogging: If the sprayer clogs, ensure the paint is properly diluted according to the instructions in Section 5. Use the provided cleaning needle to clear any blockages in the nozzle. If the nozzle is disposable and severely clogged, replace it.
- Uneven Spray/Splattering: This often indicates improper paint consistency. Adjust paint dilution as needed. Ensure the nozzle is clean and correctly installed.
- Dripping: Verify that the paint bottle is kept in an upward position and not tilted excessively downwards during operation. Check for any loose connections or damaged nozzles.
- No Spray: Check if the battery is charged. Ensure the spray bottle is correctly installed and contains paint. Verify the nozzle is not completely blocked.
- Battery Life: If battery life seems short, ensure it is fully charged before each use. Operating in extreme temperatures can affect battery performance.
