the spools come with line already installed,they are all for bolens,line is generic,you buy your own line,there are 2 different sizes,and a bunch of types,like round or star,you buy generic line because bolens wont make any money if they sold "BOLENS" line.

For your machine, make sure you are using the Manufacturer's recommended trimmer line. For your model, they recommend using Echo brand .080" Cross Fire diameter line. You also need to insure that when you load the spool with the line, that it is loaded (in the right direction) so it can feed properly.

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.

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

The long bolt coming down at the end shaft like place reel over bolt then turn back and forth slowly while pushing upward and it should lock in and take knob or bolt at end and tighten to the right.

Remove the head, the reel, a knob and a spring will fall out if you arentcareful. Cut about 25 feet of proper size line. Pull 12 or so feet throuth the little hole in the reel and wind the string in the direction indicated on the reel. Leave about 6 inches sticking out on each side. There is a notch on each side to hold the string while you reassemble it. Insert the string into these notches. Reassemble the device and trim away while recalling all sorts of wonderful memories of the times you spent with your dad.

there are 2 places you need to push in to remove reel

After you line up the two triangles, push in and lift. Only the top piece will come off, then the spool is inside. I kept trying to lift the whole head and then the top popped off and I realized what I was doing wrong. It is actually quite easy once you figure out the correct way and where to pull.

To install string in the Ryobi you do not have to disassemble anything: Line up the two arrows on the inner and outer reel, remove any excess string, cut two pieces of string about 10 feet, feed line in the side holes, secure line in hole where it comes out the bottom (it only takes about 1/4in. to do so), pull strings tight, then turn the inner reel counter clockwise to wind it. If it sticks a little just pull line a little.
To remove the inner spool in order to remove line that has broken inside, to clean the mechanism, or to perform other maintenance, grasp the outer reel and unscrew the bump knob counter-clockwise. Mine is often very tight and requires pliers to get enough leverage. While you are in there, clean the inner reel and the inside of the outer reel to improve feed performance. The shaft rarely needs cleaning. Do not lubricate. After re-installing the reel, add string (0.080") as described above.
