The handle pushes down and locks to be carry or to unscrew it. Push handle down, then twist left to unscrew. It may take a bunch of force to start. Better to hold the sprayer down and relieve all pressure before doing the unscrew.

Howdy chloebuckski,This is a question that I get quite often. Here is the answer; with some pressure push the handle inward while turning counterclockwise. When you feel the handle sink in, keep turning and you've got it.Hope this helps,Coach Davecommunity.homedepot

Howdy Mlavin55,It sounds like your trying to find the way for the handle to catch the threads. In this case you need to push down on the handle as you turn it counter clockwise. Within about a half turn the handle will sink just a little. Now you've got the threads and simply keep turning counterclockwise and you got it.Happy Gardening,Coach Davecommunity.homedepot

type roundup spare parts into your search box then brose the list that comes up

it should tell you on the induvidual bottles/cans of weed/grass what proportions of liquid/water to use.

Howdy g5483,Most reputable retailers' will either let you exchange the sprayer or get you the part. At The Home Depot we will gladly do either one to get you what you need. Coach Dave

Howdy MMis971,The sprayer just needs to be pushed down by the handle as you turn counter clockwise. This can be made a little easier by unscrewing the nozzle where it connects to the tank to release any pressure built up by pumping. Happy Gardening,Coach Dave

Check under the lid/cover for a rubber gasket. This may have gotten unseated when putting the sprayer top on. It must form a tight seal around the lip of the sprayer top in order to keep the pressure. Alternative: Put water in the sprayer leaving some air on top to build pressure. Put a few drops of dish soap inside and gently stir. Put the cover on, and tilt the sprayer to coat all areas at the top. Start pumping and see where the bubbles come out---there is your leak. If it is near where the sprayer hose enters, and it is a permanent mount, you may have a bad seal. If the sprayer hose unscrews, you may need a new rubber washer inside. If bubbles come out of the wand, or other plastic seams, you may have a crack in the plastic. Depending on the location, you could epoxy over the crack to seal it permanently. Good luck.

I would return it to where you bought it. It sounds like the seal between the cover and the container is defective. Take a small container of soapy water and gently sponge it all around the cover of the sprayer. Pump it up and note where the bubbles form--this is where your leak is.
If you are not able to return it, check to see if there is a rubber insert that should be evenly seated around the cover where it screws on. You may be able to tighten that gap by using pipe thread tape around the ridges, but this is a temporary situation.

Hello,
Yes I do use it, you can put about 1qt of round up for every gallon of water. This should kill your weeds, for most precise mixing instructions check the bottle label.
Thanks.
