Chapin Sprayer Instructions

1. Hose to Tank

Ensure the white outlet tube is attached to the outlet tube adapter. Insert the outlet tube portion of the discharge assembly into the tank adapter. Ensure proper placement of the white outlet tube. Firmly insert the outlet tube adapter into the tank adapter, aligning the tab with the notches on the tank adapter. Firmly tighten the retaining nut to the tank adapter.

2. Nozzle

Attach the nozzle to the shut-off handle or extension wand. Available spray patterns include Cone spray and Stream spray.

3. Filter

The filter helps prevent clogging. It is located on the end of the white tube inside the sprayer tank. To clean the filter, remove the hose from the tank and lift out the outlet tube. Make sure the filter is positioned at the bottom of the tank.

4. Pre-Use Check

• Check tightness of the hose nut to ensure the hose is securely attached to the tank outlet.
• Inspect the hose for deterioration, cracks, softness, or brittleness. Replace the hose before use if any of these conditions are found, using only original manufacturer's parts.
• Remove the pump. Inspect the interior and exterior of the tank for signs of deterioration of the body and bottom. Any sign of deterioration indicates possible tank weakening and could result in explosive bursting under pressure. If any signs are found, discard the tank immediately and replace it. Do not attempt to patch leaks.
• Follow Filling, Pressurizing, and Spraying Instructions, but use water only. Pump the plunger 10-20 strokes and inspect for leaks.
• Direct the shut-off away from you and open it to ensure the discharge is not clogged.
• If the unit passes this test, release pressure, empty the tank, and proceed with Filling, Pressurizing, and Spraying Instructions.
• Inspect all metal parts, including the wand, nozzle, and fittings, for rust, corrosion, and pitting. Replace affected parts with original manufacturer's parts before using.

5. Filling

• Turn the pump handle counterclockwise and remove the pump.
• Prepare the spray solution following all directions and safety warnings on the chemical label.
• Fill the tank to no more than the proper gallon marker. Do NOT overfill to accommodate the pump.
• Check the pump to ensure no grass or dirt is stuck to the barrel. Replace the pump in the tank and tighten securely.

6. Pressurizing and Spraying

• Turn the handle clockwise to tighten. Push the handle down, then turn 1/4 turn counterclockwise to release.
• Pump until you feel resistance.
• Push the handle down and turn 1/4 turn clockwise to lock. Begin spraying. Repump the sprayer as required to maintain spray force.

7. Fatigue-Free Spraying

For constant spraying, push down on the shut-off handle and move the locking mechanism away from you. To release, squeeze the handle and move the locking mechanism back towards you.

8. To Release Pressure

Your sprayer is equipped with a pressure relief/release valve. To release pressure, lift and hold the cap until air is completely exhausted, OR, turn the valve slowly counterclockwise until you hear air escaping and wait until air is completely exhausted. Stay away from the sprayer until all air has escaped.

9. Wand Dock Clip

Choose the holder that fits your wand.

10. Care, Storage and Maintenance

• Follow chemical manufacturer's instructions for cleaning. Rinse thoroughly with the recommended solvent. Follow Filling, Pressurizing, and Spraying Instructions, but pump the unit only 8-10 strokes. Ensure the wand and nozzle are thoroughly rinsed with water after each use.
• Open the shut-off and allow the recommended solvent to run through the discharge assembly.
• Release pressure, remove the pump, and empty the sprayer.
• Store the sprayer tank upside down, with the pump removed, in a warm dry location.
• Periodically oil the pump by dropping 10-12 drops of light oil down the pump rod through the opening in the cover.
