Use rubber gloves to remove the top from the jar and wash completely to remove any poisons. Turn lid upside down and examine suction tube for breaks and clogging. If tube is broken, discard whole thing and try another brand. There are four phillips head screws readily visible. Remove screws to reveal innards of gadget. The suction tube has a spring on it. If tube is clogged you can now try to get water through it and flush . If it is clogged and does not flush, throw the thing away. My suction tube was ok, but the thing wouldn't work. Now look at the dial, which is loose. Note which side is up and, when you take it off, note the hole with the black o-ring under it.Now look at the dial. You will see a series of holes, starting with a big one and progressing to tiny ones. Suction through these holes makes the thing work and a given setting will not work if its hole is clogged. Do not try to poke something in the holes. That would spoil your calibration. Use an air compressor, if you have one, to blow out each hole from each side. No compressor, try a straw. Reassemble, maybe having a helper hold it together against the spring tension while you put the screws in. Put some water in a cup, attach hose, turn water on and see if water disappears from the cup at each setting. Worked for me.

SOURCE: I have a ortho tree & shrub spray-ette hose

sound like the inside suction hose is loose or not fitting correctly. i had a similar problem and wrapped some duct tape around the tube then snugly fit it inside the cap. no outside air suction and it works fine. i've had mine going on 15 years and use it constantly.

"The instructions on Ortho Garden Disease Control (Daconil) give directions for use in the dial and spray. Set dial at 4 Oz. Add 1 TBS Daconil and 7 TBS water for each gallon you want. I am using the dial and spray and don't see as much residue as when I was using a pump spray.

Here is what they say at their site:

{ ...
How do I use the Ortho Dial 'N Spray Multi-Use Hose-End Sprayer?
Pour product into jar, and set dial to amount indicated on product label and begin spraying. This sprayer siphons product and mixes while spraying; it does not mix inside the sprayer.

Which means it is not determined by Scotts, but by the product you want to disperse with the Dial N Spray.

And here is an exact description of the settings:

{ ... There are 14 settings in all and they range from 1 teaspoon per gallon up to 8 ounces per gallon. You will find the dial at the on the top of the sprayer. ... }

SOURCE: I am confused. Your driveway

Hey, sorry for the confusion. Actually Ortho GroundClear can not be used in the Dial N Spray Hose End Sprayer because this sprayer will only dilute up to 8oz per gallon. This dilution rate is not enough for the product to be effective in keeping the area clear of vegetation. Hope this clears it up.
