REFILLING TRIMMING LINE
1.
For replacement line, use a diameter of .095 in. (2.4 mm).
The spool is capable for a line up to 20 ft. (6 m) on the 4 in.
head. Avoid using a larger line as it may cut down the
trimming performance.
Pinch the slotted area on the both sides of the spool
housing to unhook the bottom cap.
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.
While holding the spool against the housing, pull the line
ends to release them from the slot.
Line up the slot on the bottom cap with the hook on the
housing, press the cap against the housing until it clicks.
