Hi Robert
Your pump probably needs priming.
Hold the triggger down and squeeze the bottle at the same time to create a pressure inside of the bottle of spray to prime the pump.

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

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

The Pump N Go can be refilled with either the Roundup Super Concentrate or Roundup Ready To Use Plus Refill Bottle.

To refill the Pump N Go with the Roundup Super Concentrate (purple cap), add 6.5 fl oz of the Super Concentrate to container and slowly fill with water.

To refill with the Ready To Use Plus Refill bottle, just slowly fill the Pump N Go with the refill container.

We do not recommend using Roundup Concentrate Plus (red cap) to refill the Pump N Go because it has different active ingredients and different information regarding use around edibles.

To open to Pump N Go container, please follow the directions below:

Stabilize container by holding between your feet

While holding the pump handle push down slightly and turn left (the pump will be out of the locked position)

The first time it is opened it will be difficult to open because for shipping safety the top is but on very tightly at the factory.

If you have any further questions, please contact us at 877-465-5160.

This is probably a RTU bottle that is designed for non-refilling since it assumes the purchaser doesn't know the correct ratio of water to pure roundup.

Any Roundup Weed & Grass Killer RTU can be refilled with the new 1.25 gallon Roundup Weed & Grass RTU Refill bottle OR use Roundup Super Concentrate (purple cap).

Directions to Refill with Roundup Super Concentrate

• 24oz RTU: 1 oz of RoundUp Super Concentrate, fill with water very slowly to avoid foaming.
• 1/2 Gallon RTU: 2 1/2 fl. oz. of Roundup Super Concentrate and slowly add 1/2 gallon of water
• 1 or 1.1 Gallon RTU: 5 oz RoundUp Super Concentrate, fill slowly with 1 gallon of water
• 1.33 Gallon (PNS & PNG): Add 6.5 fl oz of the Super Concentrate to container and slowly fill with water

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.

For 5L of water 50ml of roundup can be used. Remember Roundup works by being absorbed by leaves not through the soil so spray in calm weather and shield your plants with a bit of cardboard or plastic if you need to get really close.

Put a little wd-40 or light oil down in the plunger shaft to get the leathers on the pump plunger to seal back against the cylinder wall. Work it a little and u will feel the pressure come back. Maybe some dish soap would work too if u like bubbles.
