HOW TO PREPARE YOUR UNIT FOR USE:
1. Always oil the seal inside the cap of unit before using, as well as the check valve. This will extend life
of seal, and it is important for obtaining a leakproff barrier.
Hook the plastic clip attached to the shoulder straps into the appropriate lateral
opening on the base of unit.
Attach spray wand to spray gun and firmly tighten. To adjust nozzle, tighten (turn
clockwise), cap for a fine atomized spray, or loosen (turn counter-clockwise), for a
coarser spray or solid stream.
THE SPRAYER IS NOW READY TO USE.

A unit that has been used with herbicides should never be used to spray insecticides, unless the sprayer has
been properly cleaned and all other chemicals neutralized. Failure to do this could cause you to kill plants
sprayed. Consult with the manufacturer of the chemicals in use for proper instructions.
Remove cap.
Mix solution in a separate receptacle, following manufacturer's directions on the container.
Pour pre-mixed solution into sprayer and fasten cap securely.
Place sprayer on back and pressurize by pumping approximately 5 to 11 times.
Normal working pressure should be from 25 psi to 40 psi. Too much pressure will waist chemical and over
apply, as well as causing potential damage to pump tube.
Pump occasionally to maintain the desired spraying pressure.

depressing trigger for at least 2 minutes. Then drain all remaining water from tank, and repeat this process
twotimes. Toproperlyneutralizechemicals,aneutralizingsolutionmentionedinthe"Trouble-Shooting"guide
