There are two or more types,
1: provided the spool is full and wound on correctly, to increase the length of nylon you tap the head of the snipper on the ground while it's spinning. This should release extra cutting string.
2: others are simply feed by the centrifugal force governed by a spring in the head. When you wrap the nylon string around the spool, then feed the nylon out the holes provided, the weight of the nylon string pulls the required amount of nylon out so you can continue to work.
Others are manual, simply pull the nylon out by hand to the desired length.
Note that you are only cutting with the very tip of the nylon string, not the full length.

Pull the head off by turning the inner hub counter clockwise while holding the outer head still. Once the inner head pops out, turn it over and look for the string rotation arrow. If you can't find the string winding directional arrow, start the trimmer and determine shaft rotation direction (generally counter clockwise) and wind the string in the same direction as the head rotates when installed.
Pull about 5 arm lengths of string out of a string spool and cut it off. Place the inner trimmer head on an object that will hold it while you pull the string to even lengths through the winding hole (the support brackets of a pickup truck tail gate work well for holding the inner head while doing this).
Begin wrapping the string double wraps in the proper direction, laying them evenly and closely to the previous wrap, working it back and forth as the string begins to build up. Avoid crossing the string over itself more than necessary, the string can weld itself together if the strands cross to awkwardly. Once the string is wound, hold the head with one hand and slide the string through the outer head holes, avoid letting the string come unwrapped.
Carefully place the inner head down into the outer header. Avoid letting the string get caught between the inner and outer head. Once the heads are together lock the inner head onto the outer head by turning it and locking the round knobs into the outer head slots.
You can trim the string or let the trimmer guard do it. If the string doesn't feed it is either wound the wrong way, tangled between the inner/outer head or welded to itself.

pull head off cut 1 piece of line bout 48 inches should be a **** in center of head put center of line in slot then roll line in same direction in both slots lock ends in head reinstall

Unscrew the head's center bump-knob counterclockwise with your fingers. Pull the bump knob off and take the spool cover off the head. Slide out the spool and any remaining cutting line. Lift out the spring underneath the spool. Take out the slide washer. Unscrew the arbor bolt either clockwise or counterclockwise, depending on model, in the center of the trimmer head using the wrench. Take the entire head off the end of the shaft.

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

There is a screw underneath the Toro label.   I learned the hard way.

Invert the trimmer pull the center of the head straight off. Wind new line in counter Clockwise direction. There should be a hole or notch to place the center of the string in. insert each end of the sting through one of the holes in the head and reinsert the spool into the proper position. Be sure that the automatic advance is movable by pressing down and pulling out more string. Cut string to proper length and restart your trimmer
