7. Maintenance and Storage
Proper maintenance ensures the longevity and performance of your sprayer:
- Cleaning: After each use, empty any remaining liquid from the tank. Rinse the tank thoroughly with clean water and mild soap. Operate the sprayer with clean water for a few minutes to flush the pump, hose, and wand.
- Nozzle care: Clean nozzles regularly to prevent clogging. If a nozzle becomes clogged, remove it and rinse with water. A small brush or pin can be used to clear stubborn blockages.
- Battery care: Store the battery in a cool, dry place. For long-term storage, charge the battery to approximately 50% capacity.
- Winter storage: If storing in freezing temperatures, ensure all liquid is drained from the sprayer to prevent damage from ice expansion.
- General storage: Store the sprayer in a dry, protected area, away from direct sunlight and extreme temperatures.
8. Troubleshooting
If you encounter issues with your sprayer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Sprayer does not turn on | Battery not charged or improperly inserted | Ensure battery is fully charged and correctly seated in the compartment. |
| No spray or weak spray | Clogged nozzle or filter | Clean the nozzle and check the filter at the bottom of the tank for blockages. |
| Leaking from connections | Loose hose or wand connections | Tighten all connections. Check O-rings for damage and replace if necessary. |
| Motor runs but no liquid sprays | Tank is empty or suction line is blocked | Refill the tank. Check the suction line for kinks or blockages. |
