2. Important Safety Information
Always prioritize safety when operating the sprayer. Failure to follow these guidelines may result in injury or damage to the equipment.
- Read all instructions: Before using the sprayer, thoroughly read and understand all instructions in this manual and on the chemical product labels.
- Wear protective gear: Always wear appropriate personal protective equipment (PPE) such as gloves, eye protection, and long-sleeved clothing when handling chemicals and operating the sprayer.
- Handle chemicals with care: Follow all instructions and warnings on the chemical product labels. Do not mix incompatible chemicals.
- Caution under pressure: The sprayer operates under pressure. Never point the nozzle at people or animals. Release pressure before opening the tank or performing maintenance.
- Ventilation: Use the sprayer in well-ventilated areas to avoid inhaling chemical fumes.
- Storage: Store the sprayer and chemicals out of reach of children and pets, in a cool, dry place.
3. Setup and Assembly
Your Chapin sprayer comes largely pre-assembled. Follow these steps for initial setup:
- Unpack: Carefully remove all components from the packaging. Ensure all parts are present: tank, pump assembly, hose, and spray wand with nozzle.
- Attach Hose: Connect the hose to the tank outlet and the spray wand. Ensure connections are secure to prevent leaks.
- Prepare for Filling: Ensure the pump assembly is removed from the tank. The wide funnel-mouth opening facilitates easy and clean filling.

4. Operation
Follow these steps for effective and safe operation of your sprayer:
- Fill the Tank: Remove the pump assembly. Carefully pour the desired liquid into the 2-gallon poly tank. Do not overfill. The funnel top design helps prevent spills.
- Secure Pump Assembly: Insert the pump assembly back into the tank and twist clockwise until it is securely tightened.
- Pressurize the Sprayer: Pump the handle up and down approximately 10-20 times until resistance is felt and the tank is pressurized. The auto and manual high-pressure relief valve provides control and safety.
- Adjust Nozzle: The adjustable poly-cone nozzle allows you to change the spray pattern from a fine mist to a coarse stream. Rotate the nozzle tip to achieve the desired spray.
- Begin Spraying: Point the nozzle towards the target area and depress the shut-off lever on the spray wand. The poly shut-off features a lock-on mechanism for continuous spraying, reducing hand fatigue.
- Release Pressure: After use, or before opening the tank, always release the internal pressure. This can be done by activating the high-pressure relief valve or by holding the shut-off lever open until all pressure is dissipated.

5. Care and Maintenance
Proper care and maintenance will extend the life of your Chapin sprayer:
- Cleaning After Use: After each use, especially when using chemicals, thoroughly rinse the tank, hose, and wand with clean water. Pump clean water through the nozzle to clear any residue.
- Poly Shut-off: The poly shut-off is designed for easy cleaning and requires no special tools for disassembly. Refer to the diagram for component breakdown if needed for deep cleaning.
- Storage: Store the sprayer in a clean, dry place, away from direct sunlight and extreme temperatures. Ensure all pressure is released before storage.
- Check for Leaks: Periodically inspect the hose, connections, and seals for any signs of wear or leaks. Replace worn parts as necessary.
- Nozzle Maintenance: If the nozzle becomes clogged, remove it and clean it with water. Do not use metal objects that could damage the orifice.
