■ REFILLING TRIMMING LINE (MA1)
1. For replacement line, use a diameter of .095in
(2.4mm). The spool is capable for a line upto 20ft
(6m) on the 4” head. Avoid using a larger line as
it may cut down the trimming performance.
For safety reasons, do not use
metalreinforced 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.
