SPRAYER COMPONENTS & USE INFORMATION, Continued 3 STAGE FILTERING SYSTEM This backpack sprayer is equipped with a 3 stage filtering system (see figure Stage 1 (Filter basket) Figure 1 1).

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.
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 NTE dealer and always insist on original manufactured replacement parts.
