Stage Filtering System, Filling the Sprayer

SPRAYER COMPONENTS & USE INFORMATION, Continued

4 STAGE FILTERING SYSTEM

This backpack sprayer is equipped with a 4 stage filtering system (see figure 1). Stage 1 is a filter basket incorporated into the tank opening where fluid is added. Stage 2 and 3 filters are located at the inlet of the pressure cylinder. Stage 2 is a removable In-Tank filter. Stage 3 is a removable filter cartridge integrated into the pressure cylinder. Stage 4 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.

Stage 3 filter cartridge cleaning requires removal of the entire pressure cylinder assembly (see section “disassembling and repairing the pressure cylinder”). Once the pressure cylinder is removed the stage 3 filter can be removed for cleaning (see figure 3). Periodic cleaning of the stage 2 filter is highly recommended and will reduce the need to perform this disassembly. It is best to have no or minimal fluid in the tank before removing and reinstalling the stage 2 In-Tank filter. The In-Tank filter needs to be oriented in a specific way when inserted into the pressure cylinder base (see figure 2).

The stage 4 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 4 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.
