2.4mm(.095in).The spool is capable for a line upto

line as it may cut down the trimming performance.

housing to unhook the bottom cap.

line.

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.
