REFILLING TRIMMING LINE

2.Pinch the slotted area on the both sides of the spool housing to unhook the bottom cap.
3.Take out the spool and pull off the old line. Put one end of new line through the spool holes and pull it until the length is equal between each part of the line.
4.Wind up the line in the correct direction as indicated on the spool.
5.Hook each end of the line in the slot on the edge of the spool, and then put the ends through the eyelets on the housing. Make sure that the spring and the washers are in place.
6.While holding the spool against the housing, pull the line ends to release them from the slot.
7.Line up the slot on the bottom cap with the hook on the housing, press the cap against the housing until it clicks.
