SPRAYER COMPONENTS & USE INFORMATION, Continued
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.
