Directions:

Connect water supply hose to pistol grip shut-off-valve handle. Remove and fill bottle with liquid chemical concentrate.

 CAUTION: To prevent chemical loss from bottle out of air vent hole in mixing head, sprayer must remain in upright position at all times.

Turn dial to desired mixing rate letter to siphon chemical at the specific ratio. This will automatically mix chemical with water at the factory pre-set dilution rate selected on dial. Pistol grip shut-off-valve lever must be fully depressed for accurate mixing.

Also, use the Deflector Tip for covering large areas and remove it for a solid stream that will carry up to 25 feet. Use the foam wand for enhanced foam application.

For a powerful clear water rinse, remove handle from siphon head and use as an insulated water nozzle.

Pull back snap ring on female quick coupler to detach or reattach handle to mixing head. For a more gentle rinse without removing handle, move dial to off setting.

IMPORTANT NOTE: Handle supplied with gun contains an anti-siphon to protect water supply from accidental chemical contamination. (Note: A slight discharge of water from base of handle when water is turned off is normal and indicates anti-siphon is functioning properly.) DO NOT USE ANY OTHER HANDLE WITH THIS SPRAYER. If replacement is needed, a handle with anti-siphon installed should be obtained from your supplier.

Also, use the Deflector Tip for covering large areas, and remove it for a solid stream that will carry up to 25 feet. Use the foam wand for enhanced foam application.
