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. 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.
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.
LOCK-OFF POSITION
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.
Note: If you experience a rapid drop in pressure, drain the sprayer completely and pump the handle
with an empty tank. The pressure chamber will fill with the required volume of air to repressurize.
Perform this procedure from time to time as routine maintenance.
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.
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.
