Assemble the nozzle and wand by screwing the nozzle onto the extension wand and securing it to the shut-off handle.
Ensure all fittings are tight and correctly aligned before filling the sprayer.

Operation and Use

Filling: Unscrew the pump handle and fill the tank with the prepared spray solution. Do not overfill beyond the marked level.
Pressurising: Pump the handle until resistance is felt, then lock into position.
Spraying: Begin spraying and re-pump as needed to maintain pressure.
Releasing Pressure: Lift or turn the pressure relief valve until all air has been released.

Maintenance and Storage

Rinse the sprayer thoroughly after each use following the chemical manufacturer’s guidance.
Store upside down with the pump removed in a dry location.
Periodically oil the pump shaft with light oil to maintain smooth operation.
Inspect hoses, seals and fittings regularly and replace worn parts with genuine Chapin components.

Safety Information

Always wear protective gear — goggles, gloves, long sleeves and footwear — when spraying. Do not use the sprayer with flammable or corrosive materials such as acids, bleach, or chlorine-based chemicals.
