HOW DO I INSTALL A NEW STRING IN A PRO CUT 11 for Ryobi RLT30CD trimmer

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
