Important Safety Information
Always follow the manufacturer's instructions for safe operation and disposal. Never over-pressurize the tank and avoid contact with chemicals. In case of accidental release, rinse immediately with water and seek medical attention if necessary. Always store the sprayer in a cool, dry place away from heat sources and direct sunlight.

Key Components:

- Tank: 2.25-gallon, UV-resistant HDPE with translucent color for level monitoring.
- Pump: High-efficiency piston pump for quick pressurization.
- Seals: Viton® seals and O-rings for superior chemical resistance.
- Wand: Unbreakable wand with interchangeable nozzle system (TeeJet® compatible).
- Valve: Commercial-quality shut-off valve with lock-on/lock-off lever.
- Pressure Relief Valve: Automatically vents pressure once the maximum compression level is reached (at 45 psi).
- Carry Strap: Adjustable webbed nylon carry strap.
Setup and Assembly
- Unpack Components: Carefully remove all parts from the packaging. Verify all components are present: tank, pump assembly, hose, spray wand, and nozzles.
- Attach Hose: Securely connect the hose to the tank outlet and the spray wand handle. Ensure connections are tight to prevent leaks.
- Install Nozzle: Select the desired nozzle and attach it to the end of the spray wand. Ensure it is firmly seated.
- Initial Inspection: Before first use, inspect all seals and O-rings for proper placement and any signs of damage. Lubricate seals with a suitable lubricant if necessary.
Operating Instructions
- Prepare Solution: Ensure the chemical solution is mixed according to its manufacturer's instructions.
- Fill Tank: Unscrew the pump assembly from the tank. Pour the prepared solution into the tank, being careful not to exceed the maximum fill line. The extra-large opening facilitates easy filling.
- Secure Pump: Reinsert the pump assembly into the tank opening and screw it down tightly. Ensure a secure seal to prevent leaks and maintain pressure.
- Pressurize Sprayer: Pump the handle up and down repeatedly until resistance is felt and the tank is pressurized. The high-efficiency pump requires fewer strokes. The pressure-relief valve will automatically vent if over-pressurized (at 45 psi).
- Begin Spraying: Aim the nozzle at the target area. Squeeze the trigger on the shut-off valve to begin spraying. For continuous spraying, engage the lock-on feature on the trigger.
- Adjust Spray Pattern: Rotate the nozzle to adjust the spray pattern from a fine mist to a coarse stream, depending on the application.
- Cease Spraying: Release the trigger to stop spraying. Disengage the lock-on feature if used.

Maintenance and Storage
- Cleaning After Use: After each use, thoroughly rinse the tank, pump, hose, and wand with clean water. Pump clean water through the nozzle to flush out any chemical residue.
- Disassemble for Deep Cleaning: Periodically, disassemble the nozzle and wand components for a more thorough cleaning.
- Inspect Seals: Regularly inspect all Viton® seals and O-rings for wear or damage. Replace any worn parts to maintain proper sealing and prevent leaks. Lubricate seals with silicone grease to prolong their life.
- Depressurize: Always release all pressure from the tank before storing.
- Storage: Store the sprayer in a cool, dry place, away from direct sunlight and freezing temperatures. Ensure the tank is empty and clean.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sprayer does not build or hold pressure. | Loose pump assembly, damaged or dry O-rings/seals, clogged check valve, worn pump cup. | Ensure pump assembly is tightly screwed onto the tank. Inspect and lubricate or replace O-rings and seals. Clean or replace the check valve. Inspect and replace the pump cup if worn. |
| Leaking from tank lid or connections. | Lid not tightened sufficiently, damaged lid gasket, loose hose connections. | Tighten the tank lid firmly. Inspect and replace the lid gasket if damaged. Ensure all hose connections are secure. |
| No spray or weak spray. | Clogged nozzle, insufficient pressure, clogged filter. | Clean the nozzle. Pump the sprayer to full pressure. Check and clean the filter at the end of the dip tube inside the tank. |
| Bottom of tank bulges. | Over-pressurization. | The pressure relief valve should prevent this at 45 psi. If it occurs, immediately release pressure. Do not over-pressurize the tank. If the tank is deformed, discontinue use and replace. |
