3 STAGE FILTERING SYSTEM

This backpack sprayer is equipped with a 3 stage filtering system (see figure 1). Stage 1 is a filter basket incorporated into the tank opening where fluid is added. Stage 2 filter is located at the inlet of the pressure cylinder. Stage 2 is a removable In-Tank filter. Stage 3 is a removable filter incorporated into the shut-off assembly. Periodic cleaning of these filters is recommended to insure consistent fluid flow through the sprayer. This will also reduce sprayer component wear.

The stage 3 filter is a removable filter incorporated into the inlet side of the shut-off valve (see section “disassembling and repairing the shut-off valve”). Make sure pressure is released before detaching the hose from the shut-off. It is best to have no or minimal fluid in the pressure cylinder before removing and reinstalling the stage 3 shut-off filter as fluid can leak from the hose.

FILLING THE SPRAYER

Make sure the filter basket is in place to keep debris from entering the tank.

Determine the amount of mixture needed for your application. Add the proper amount of water to the tank. Add the proper amount of chemical to the tank (check the chemical label for proper ratio of chemical). Stir mixture in tank with a clean utensil (like a paint stirrer). The tank will hold the 4-gallon (15.1L) capacity plus the chemical.

It is not necessary to completely fill the sprayer tank with each use. You can fill the tank with only the amount needed for each application.

Always follow the manufacturer's instructions included on their product label.

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.

LOCK-ON POSITION NEUTRAL POSITIONLOCK-OFF POSITION

Locking Mechanism Handle Up Handle Down

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.

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.

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.
