■REFILLING TRIMMING LINE (MA1)
WARNING
For safety reasons, do not use metalreinforced line.
1.For replacement line, use a diameter of
.095in (2.4mm). The spool is capable for a line up to 20feet (6m) on the 4” head. Avoid using a larger line as it may cut down the trimming performance.
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. Fold new line so that one half line is 4.7in.(12cm) shorter than another half. And then, hook bended end in the slot of the spool.
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.

NOTE
Screwing in the screw too tightly may make it impossible for the blades to move. Conversely, not screwing in the screw tightly enough may make the blades of the trimmer feel dull and cause leaves and branches to become caught in the blades of the trimmer.
QUICK TIP
If the blades become so worn down that it is no longer possible to eliminate the gap between them, you should contact the authorized RedMax servicing dealer from which you purchased your RedMax trimmer to have the blades resharpened or replaced.
