General Cleaning of Handheld Sprayer:

Always empty the sprayer and clean the tank thoroughly after each use. fill with water and replace Pump Cap tightly. Pressurize the unit by pumping (15 pumps). Squeeze shut-off (discharge) to empty contents through the nozzle. Repeat as needed.

Cleaning the shut off (Discharge handle):

Pull handle straight up to disassemble handle from shut-off. Insert notches from underside of handle into plunger grooves on the top of shut-off barrel and turn counterclockwise using the handle like a wrench. Remove plunger, diaphragm and spring from inside the shut-off. Wash the shut-off diaphragm with mild detergent.

Reassemble:

Hold shut-off upright and place spring in hole, place diaphragm on top of spring and reassemble plunger and tighten. Tighten plunger clockwise until flush to top of shut-off body. Do not over-tighten or unit may not spray. To replace handle back into position on shut-off, slide forks under plunger, push handle down until it snaps into place.

Cleaning the Nozzle Assembly:

All Chapin compressed air sprayers are equipped with various nozzles for different applications. Though each nozzle provides the unit with specific functionality, all generally are configured the same way making cleaning simple and easy. Simply unscrew the nozzle by turning it counter-clockwise until the nozzle cap separates from the nozzle base. Clean both the nozzle base and the nozzle cap with appropriate cleaners recommended by the chemical manufacturer of the product you are spraying. If you insert something into the nozzle cap or base to aid in cleaning or remove debris, be careful not to force or ram out the inner cavity. This may affect the output and/or the spray pattern.

Storing and Maintaining your Sprayer:

The sprayer should be stored out of direct sunlight in a cool dry space.Before freezing weather make sure to drain all liquid in the tank, pump, pressure cylinder, hose, shut-off valve, wand and nozzle, to avoid liquid expansion and cracking in the sprayer components. Lock the shut-off valve in the “open” position When service is required call your nearest Chapin dealer and always insist on original Chapin manufactured replacement parts.Inspect the hose, wand, pump, tank and shut-off valve for wear, damage or leaks on a regular basis and repair defects promptly.
