Replace the spark plug. Strip and clean the carburetor. Replace the fuel with fresh. But hang on though, the RY40002 is electric and runs with a 40 volt battery, so no spark plug and carburetor! :>D Replace the battery, lubricate everything from the motor to the head. Check the motor with nothing attached to it. The carbon brushes may need replacing or its bearings need greasing.

Try the battery in another Ryobi to see if it works.
If it does not work it may have been effected when the trimmer burnt out.
time to buy a new battery.

it has a left hand thread which means that to unscrew it you have to turn it in a clockwise direction like putting a nut on a bolt

Gary, diagnose where the problem really lays, do you have spark, is it getting fuel. PRESS THE HELPFUL BUTTON

multiple failures with bump advance string trimmers - GardenWeb

Jul 5, 2008 - I have indeed hurled my own ryobi across the yard in a fit. ... Some heads are not designed for curved shaft trimmers or on engines under a .... the fence so thestring won't wrap around the fence instead of whipping in and out.

The motor is failing. Most likely the brushes have failed, but this is all sealed and they cannot be replaced alone.

I have a Ryobi Model RY28040 straight shaft line trimmer. In my case I replaced the complete String Head Assembly that includes the String Head Housing, Spring, and Spool and the string still did not advance. I then discovered that the bolt in the Spool Retainer cap (the red cap that attaches the spool to the shaft) was fused and not moving. The bolt needs to be loose inside the cap in order to allow the spool to move in and out by the spring. I loosened the bolt and fastened the spool back onto the shaft. Fired it up and bumped it a few times and the line began to advance. Turns out I probably only needed to replace the Spool Retainer rather than the String Head Assembly.

LINE REPLACEMENT (Fig. 8) (For Reel EasyTM Head) Use 2.4mm monofilament string. Use original manufacturer's replacement string for best performance. n Stop the engine and disconnect the spark plug wire. n Cut one piece of string approximately 7.6m in length. n Rotate knob on string head until line on knob aligns with arrows on top of string head. n Insert one end of string into eyelet located on the side of the string head and push until string comes out through eyelet on the other side. Continue to push string through the string head until the middle section of the string is inside the string head and string outside the string head is evenly divided on each side. n Rotate the knob counterclockwise on the string head to wind the string. Wind the string until approximately 20cm remains protruding from the string head. INSTALLING STRING IN PRO CUT II STRING HEAD Use monofilament string between 2.4 mm and 2.7 mm diameter. Use original manufacturer's replacement string for best performance. n Stop the engine and disconnect the spark plug wire. n Gather two of the pre-cut lengths of trimmer line provided or cut two pieces of trimmer line, in 28 cm lengths. n Insert the strings into the slots located on the sides of the string head. String should be pushed in until approximately 2 cm protrudes from the holes on the top of the string head. n Remove old string by pulling it from the holes located on the top of the string head. http://www.screwfix.com/sfd/i/cat/pdfs/89/p4763889.pdf

it sounds like the centrifugal clutch is slipping. take it to several shops and get some quotes. Most times you'll find that fixing a Ryobi is more expensive than buying a bnew one.

You can buy new Line to re-spool on your existing head
