How do you restring a Bolens 110 weedeater?

To restring a Bolens 110 weedeater, first, turn off the engine and disconnect the spark plug for safety. Then, remove the spool from the trimmer head by pressing the tabs and pulling it out. Feed the new trimmer line through the eyelets in the spool, winding it in the direction indicated on the spool, and leave enough line to extend out of the eyelets. Finally, reassemble the spool back into the trimmer head and ensure it clicks securely in place before reconnecting the spark plug.
