You can fill the tank with only the amount needed for each application. Always follow the manufacturer’s instructions included on their product label. 4E 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 lockon 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 Locking Mechanism LOCK-ON POSITION NEUTRAL POSITION Handle Down Handle Up Figure 1 Figure 2 Figure 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. Agitator Bar This sprayer is equipped with an agitator bar which facilitates mixing as the pump is operated. 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. 5E STORING / MAINTAINING YOUR SPRAYER • The sprayer should be stored out of direct sunlight in a cool dry space. • Before freezing weather make sure to drain all liquid in the tank, pump, pressure cylinder, hose, shut-off valve, wand and nozzle, to avoid liquid expansion and cracking in the sprayer components (See “Cleaning” section). Lock the shut-off valve in the “open” position. • When service is required call your nearest dealer and always insist on original manufactured replacement parts. • Inspect the hose, wand, pump, tank and shut-off valve for wear, damage or leaks on a regular basis and repair defects promptly. • Every year prior to spraying remove felt gasket (see Pump Disassembly and Rebuild) and saturate with a light oil. Oil periodically thru out the season as needed.
