A: The spark plug needed for the CS-590 is, NGK BPM-8Y.
A: To remove the spark plug from your ECHO product, turn the spark plug counter clockwise using a 19 mm socket or scrench. The spark plug boot can be removed by simply pulling up on the boot. The boot is not held in by anything else. If you still require assistance, feel free to contact ECHO's Consumer Support Department at 1-800-432-ECHO (3246).
A: You will need a deepwell socket wrench, but you won’t need to buy a whole new socket set. You can buy special spark plug sockets individually. Just be sure to get the right size—an answer to another question said that it’s 19mm. You will also need something to turn the socket and give you leverage, so you’ll have to buy another ratchet, or socket wrench. Again, socket wrenches come in a few sizes. Most likely you’ll want a 3/8, but check it with your new spark plug socket to be sure they work together. As for getting the boot off, I would first try it while you are wearing gloves. They grip better than bare hands. Twist it around a little to loosen any corrosion and wiggle it back an forth some. If that doesn’t work, try using a pair pliers, just don’t squeeze any harder than you have to.
