How do you use control knob on the Bonide All Seasons Horticultural and Dormant Spray Oil RTS? The control knob has 3 indicators; Off, Water, and On. The instructions are confusing as it says "turn to water", so what does turning the knob to "on" do? Will the spray oil come out when the knob is on "water" or "On" ?
You can quick view the step by step instructions below: HOW TO USE READY-TO-SPRAY CONTAINER
Shake container thoroughly, then attach to garden hose.
Turn on water supply at the source. Water pressure will build in hose since the sprayer is already in the "OFF" position.
To apply product, bend safety tab and turn the control valve clockwise to the "ON" position.
When spraying is complete, turn the control valve back (counterclockwise). Turn the water off. Disconnect hose from applicator and store product in original container.
