vue - How to assemble a Hozelock Pressure Sprayer

1. please make one for 5 liters !!!!
2. I bought an 8 litre general purpose pressure sprayer (no instructions) it was already connected up on arrival (bar carry strap) but I've no idea how to get the top off to put water in and no decent opening for the dissolvable packets of weedkiller.
   There seems to be an inner chamber which only holds a tiny amount of water which I had to trickle in. YouTube videos so far are an American woman and one guy with an Irish accent. I can't understand either of them.
3. wonderful ! clear and accurate, easy to follow and very necessary. i would have spent ages trying to find the inlet.
4. I endorse the comments of Libbamacushla. The instructions are awful.
5. Can you provide a video, please , regarding assembly of the 5L pump? (4505). The instructions provided with the product are worse than useless.. The photos don't give a full picture and don't inform adequately .. I have assembles many items before and these are the worst "instructions" I have come across.. eg., colour variations in attachments ( eg Red vs Grey) are presumably made for specific purposes.. yet the instructions are in black and white....impossible to decipher which part is x colour and which is Y colour.. & the photos are miserly, conserving space and costs at the cost of legibility and clarity. very frustrating...
6. Job done my arse!
   How about showing how to connect the reel to mains water, my reel has two solid connecting fittings which look like one of them should be drilled out to allow the passage of water................well?
7. Thanks so much for very clear instructions. They saved me a trip back to the garden centre as I thought I was missing a part!
8. Cheers Phil, found this very useful as the instructions were pants!! Cheers mate
