Instruction Manual

G362D, G364D Insecticide and Fertilizer Sprayer

INSTRUCTIONS AND WARNINGS
Note: Your sprayer may be packaged with its spray deflector (1) inside the bottle (6), for shipping purposes.
Attach deflector by simply pressing it onto the brass head. Firmly press to snap in place. Rotate to adjust spray pattern.
The following parts are available separately.
For replacement parts, please call
1-800-950-4458.

WARNING
Never spray flammable, caustic, acidic, chlorine, bleach or other corrosive solutions or heat, pressure, or gas producing chemicals. Always read and follow chemical  manufacturer’s instructions before use with this sprayer as some chemicals may be hazardous when used with this sprayer.
Always wear eye protection that complies with current ANSI Standard Z87.1.
Do not spray during windy conditions or allow spray to reach people or animals.
Clean sprayer and bottle thoroughly after each use to prevent contamination between different chemicals.
The handle is equipped with an anti-siphon device to prevent chemicals from being drawn back into hose. Do not substitute handle.
Do not set dial between numbers. Any such setting sprays more than 10 tablespoons/teaspoons per gallon.
Before using, read and understand chemical manufacturer’s instructions and warnings as well as those in the sprayer instruction pamphlet.
Do not spray water into an electrical outlet. Severe electrical shock could result in death.
FAILURE TO HEED ALL SAFETY WARNINGS AND INSTRUCTIONS COULD RESULT IN SERIOUS BODILY INJURY OR PROPERTY DAMAGE.

TESTING FOR PROPER SETTINGS:

This is especially recommended if the dilution rate of the chemical is critical. For more precise metering, use the teaspoon orifice for teaspoon settings when possible. Fill the sprayer bottle with the chemical concentrate. Set the dial to the recommended setting and attach the water supply hose. Carefully check the level of the contents of the sprayer bottle, spray one gallon into a measured container, and note the level of contents of the sprayer bottle. The amount of chemical used should be equal to the setting. If more  was used, you need to move the dial to a lower setting and test again. If less was used, you need to move the dial to a higher setting and test again.

CLEANING YOUR SPRAYER

It is important that you flush out your sprayer after each use. This is to ensure trouble-free siphoning action and reduce any contamination between chemicals.
1st: Remove chemical from bottle and fill with clear water.
2nd: Set the dial to number 10 and spray until bottle is empty.
If the sprayer has not been cleaned, the next time you use it, it may not siphon properly. This means that some dried chemical has clogged one or more of the openings in the mixing head. If rinsing does not clear the openings, then soak the mixing head in warm soapy water, rinse and try spraying again.
If a weed killer has been sprayed, wash the bottle and mixing head with soap and water and then follow the above procedure, but use 3 flushings. A second bottle is  recommended for use with weed killers.
When using this sprayer a back flow device (not supplied) should be installed at the hose bib.
Congratulations, you have just purchased the finest, most versatile lawn and garden sprayer available.
This sprayer combines ease of use with precise operation. A few minutes taken to read these instructions will assure you many years of trouble-free service.
It will spray commercially available liquid insecticide, fertilizer, or weed killer. This sprayer is designed to siphon water weight liquid chemical concentrates without pre-mixing. Wettable powders and thicker liquids will require prediluting as recommended in the instruction section titled “Prediluting.”
It automatically blends the full strength water weight liquid concentrate with water as you spray.
Just set the metering dial to the manufacturer’s recommended dilution rate for your chemical.
There is no waste since unused concentrate is never contaminated an can be returned to its original container.
Take a moment to familiarize yourself with your sprayer by referring to the exploded diagram and parts list.
It has four (4) major components:

1. Pistol grip handle with lever valve for instant on/off operation. This should be fully opened when using the sprayer. Be sure the hold-open clip is off before connecting to the water supply.

2. Mixing head including:
   • Metering dial with settings for 1 through 7 and 10 tablespoons or teaspoons per gallon of water.
   • Teaspoon Orifice (converter) stored in the top of the mixing head.

3. Unbreakable graduated pint polyethylene bottle with siphon tube and strainer.

4. Adjustable deflector which can be turned to direct spray up or down and is removable for a solid stream which carries up to 30 feet for spraying trees.

Your sprayer comes from the factory set to meter tablespoons per gallon and with a teaspoon converting orifice stored in the top of the mixing head.
To help you determine the proper settings for your sprayer which is calibrated in tablespoons per gallon or teaspoons per gallon with orifice converter, note the following setting guide:

SETTING| TABLESPOONS PER GALLON| TEASPOONS PER GALLON| OUNCES
PER GALLON| LITERS PER GALLON| MILILITERSS P ER GALLON
---|---|---|---|---|---
1| 1| 3| 0.5| 0.015| 15
2| 2| 6| 1| 0.03| 30
3| 3| 9| 1.5| 0.044| 44
4| 4| 12| 2| 0.059| 59
5| 5| 15| 2.5| 0.074| 74
6| 6| 18| 3| 0.089| 89
7| 7| 21| 3.5| 0.104| 104
10| 10| 30| 5| 0.148| 148

SETTING AND USING SPRAYER:

Turn the metering dial until the desired setting number is next to the setting arrows on the side of the mixing head. These arrows are located above and below the silver side body plug. EXAMPLE:
5 tablespoons per gallon; set 5 next to arrow (see drawing). Teaspoon converting orifice storage location
If your chemical calls for teaspoons per gallon of water, unscrew the teaspoon converting orifice from its storage hole on top of mixing head, insert it into the top of the siphon tube and slip the tube/orifice assembly back into the sleeve under the mixing head (see drawing). The metering dial will now read in teaspoons per gallon of water. When not in use, always store orifice in the storage hole on top of mixing head.
Fill sprayer bottle with the liquid concentrate, insert siphon tube into base of mixing head, and thread bottle into head.
Attach a water hose to handle and turn on water. When you squeeze the handle, you will automatically be spraying the proper number of teaspoons or tablespoons per gallon of water.
After spraying, do not return any unused liquid concentrate to its original container.
To spray water only, simply remove the chemical bottle from the mixing head.

PREDILUTING:

Wettable powders can be sprayed, but requires premixing. You must be careful doing this, because any small undissolved particles will clog the sprayer openings.
GENERAL FORMULA: For wettable powders, set dial to 10 tablespoons and dilute powder for each gallon of finished spray in 5 ounces of water (which is 10 tablespoons).
Directions:

1. Determine the rate per gallon of water from the product label (for example, 2 tablespoons/gallon).
2. Place the powder (for example, 2 tablespoons) in a separate container and add water to the pre-determined 5 fl. oz mark. Add in the powder (for example 2 tablespoons). Mix well to wet thoroughly and suspend the powder. Multiples of this formula may be mixed.
3. Some powders may not dissolve completely. If using such material, to avoid clumping, transfer the mixture to the spray bottle through a funnel with a 40 mesh screen such as a paint filler.
4. Set the spray dial to 10 tablespoons. The sprayer will siphon the entire 5 fl. oz. of liquid and spray the powder at the correct dosage in 1 gallon of spray.

NOTE: For certain water soluable powders where the rate per gallon is too high to mix freely with 5 ounces of water, mix it at 1/2 rate and make 2 applications, allowing the first spray to soak in thoroughly before respraying.
If the viscosity (thickness) of your liquid chemical is significantly greater than that of water, the mix ratio of the sprayer may be affected. Contact chemical manufacturer for application instructions.
IMPORTANT NOTE:
This sprayer is designed to work most accurately at 40 to 60 pounds of water pressure. At lower pressures, the dilution rate of each setting will be lower. At higher pressures, the dilution rate of each setting will be higher. If your water pressure is not within the recommended limits, you should test the amount of chemicals you are spraying at your desired setting.
