SPRAYER COMPONENTS & USE INFORMATION, Continued

HELPFUL SPRAYING INFORMATION

Use RAPID pump strokes to prime the pump. You will know the pressure chamber is filling with liquid 

when you feel firm resistance from the pump handle. The air in the pressure chamber is compressed from 

repeated strokes. By pressing the hand lever on the shut-off, the valve opens. For safety lock-off feature

(no-spraying), pull up on handle and move red locking mechanism into lock-off position as shown in fig. 

1.  To disengage, pull up on handle and return red locking mechanism to neutral position as in fig. 3.  For 

lock-on feature (continuous spraying), push down on handle and move red locking mechanism into lock-

on position as shown in fig. 2. To disengage, push down on handle and return red locking mechanism to 

neutral position as shown in fig. 3.

For easy pump action use the END of the pump handle. The amount of liquid delivered during spraying 

depends on the rate of pump stroke. The fan nozzle tip is rated at .4 gpm at 40psi. This is the nominal 

operating pressure of the sprayer..

POWDER-BASED CHEMICALS

Powder-based chemicals (powder mixed with liquids to 

make the spraying agent) are usually abrasive and can 

cause wear. When you use a powder-based chemical in 

your sprayer, make sure it is thoroughly dissolved in the 

liquid solution. Thoroughly clean and flush the sprayer 

with water to extend the life of the sprayers parts.

This sprayer is equipped with an agitator bar which facili-

tates mixing as the pump is operated.

In the event that the handle becomes stuck in the lock-on (continuous spraying) position and the tank 

pressure needs to be relieved, carefully open the tank and  place the wand inside the tank until the 

pressure is relieved.

CLEANING

1)   Always empty the sprayer and clean the tank thoroughly after each use.

2)  Pump the sprayer handle until all of the contents and air exit through the nozzle (minimum of 

30 strokes).

3)  Fill tank half way with water and pump the water out as explained in step 2 (repeat several times 

as necessary).

Other Cleaning Hints:

•   Improper spray distribution usually means the nozzle is clogged, remove the nozzle and clean it.

•   Soap can be added to the water to clean the tank.

•   Do not use strong cleaning agents or abrasives.

•   If you use a chemical agent to clean the tank follow the manufacturer’s recommendations for the 

    disposal of the waste water.

•   Follow the chemical manufacturers instructions for clean up.
