Bought a Ryobi weed trimmer CS26 from Home Depot. The second time I used it string broke both ends. Could not take it apart went to Home depot after 30 days they could not take it apart. They would not give money back. I Went home banged the string spool got vise grips finaly took off spool and replaced it with optional spool slid in string per directions every time I try to use it string flys out. What the hell? Now what?

Go to home depot where you bought it... oh wait.. they will run from you. Buy a Stihl(not sold @ teh depot) you WILL get help/service

two cycle oil you can purchase from ACE, Menards,Home Depot.... the list goes on. Good Luck...

You can look in the manufacturer web page , under manuals or just go to home depot web site and look for your model , scroll down and you will see product info and manual .

The string head on these units is very poorly designed. There is hardly anything in the head to retain the line. I suggest removing the stock string head and going to Home Depot and getting a replacement Universal type head or one for the Ryobi or Homelite They are basically interchangeable. Check the length available on the shaft end (threaded part) after removing the head.Use a large wrench or pliars to hold the dust cap when you unscrew the head. If you feel the driveshaft turning, don't continue turning head or you will break the flex driveshaft.

Maybe try replacing the faulty factory string head with a universal type head that you can purchase at Home Depot.

put a new plug and dont mix gas so strong

Sounds as tho it needs a minor carburetor adjustment. It's not getting enough fuel when you pull the throttle. Don't know if the owners manual addresses this issue or not, may want to check.

Home Depot have the string for the black and decker weed eater

I don't mean to over simplify this, but are you using fresh gas? Gas string trimmers are extremely ticky when it comes to gas. They like it SUPER fresh. And while the gas and oil mixture should be right, it can be off a little bit and still run. Try draining all of the gas out, and then filling up with fresh mix. This is ALWAYS my first step with string trimmers, and it fixes the problem 75% of the time.
Hope this helps!!
