To change the head on a Stihl weedeater, first ensure the trimmer is turned off and disconnect the spark plug for safety. Use a wrench to remove the old cutting head by turning it counterclockwise. Align the new head with the spool, threading the line as per the manufacturer's instructions, and secure it in place by tightening it clockwise. Finally, reconnect the spark plug and you're ready to go.

To replace the line on a Stihl KM56RC Weedeater, first, turn off the engine and disconnect the spark plug for safety. Remove the cutting head by unscrewing the knob at the bottom. Take off the spool and unwind any old line, then cut a new line to the desired length (typically 10-12 feet). Thread the new line through the spool holes, wind it tightly in the direction indicated, and reassemble the cutting head before reattaching it to the Weedeater.
