Setup
Before operating the Manual Watering Gun, ensure you have a compatible water supply. This gun can be connected to either a gravity feed system or a pressurized water source.
- Prepare Water Supply: Ensure your water supply (distilled or deionized water is recommended for batteries) is clean and accessible.
- Connect to Water Source: Attach the inlet connection of the watering gun to your chosen water supply hose. Ensure the connection is secure to prevent leaks. The inlet connection size is 0.67 inches and is threaded.
- Inspect the Gun: Before first use, visually inspect the watering gun for any signs of damage or loose connections.
Operating Instructions
Follow these steps for safe and effective battery watering:
- Access Battery System: Open the battery compartment or access the single-point watering system ports on your battery.
- Insert Nozzle: Carefully insert the nozzle of the watering gun into the battery's watering system port. Ensure it is fully seated.
- Initiate Filling: Squeeze the trigger on the handle of the watering gun to begin the flow of water.
- Automatic Shut-off: The gun features an automatic shut-off valve. Water flow will cease automatically once the battery cell reaches the correct electrolyte level. Do not attempt to force more water into the cell after the shut-off activates.
- Remove Nozzle: Once the flow stops, release the trigger and carefully remove the nozzle from the battery port.
- Repeat: Move to the next battery cell or battery and repeat the process until all cells are properly filled.
Important: Always use appropriate safety gear, such as eye protection and gloves, when working with batteries.
Maintenance
Proper maintenance will ensure the longevity and optimal performance of your watering gun:
- Cleaning: After each use, rinse the exterior of the watering gun with clean water to remove any residue.
- Storage: Store the watering gun in a clean, dry place, away from extreme temperatures and direct sunlight.
- Inspection: Periodically inspect the hose connection, nozzle, and trigger mechanism for any signs of wear, damage, or leaks.
- Winterization (if applicable): If storing in freezing temperatures, ensure all water is drained from the gun to prevent damage from ice expansion.
