8. Operation
ADJUSTING THE LINE LENGTH
• Your brush cutter is equipped with a semi- auto type
nylon line head that allows the operator to advance
the line without stopping the engine. When the line
becomes short, lightly tap the head on the ground
while running the engine at full throttle.
• Each time the head is bumped, the line advances
about 25 mm. For better effect, tap the head on bear
ground or hard soil. Avoid bumping in thick, tall grass
as the engine may stall by overload.
REFILLING TRIMMING LINE
1. For replacement line, use a diameter of 2.4mm(.095in).
The spool is capable for a line upto 6m(20ft) on the
10cm(4”) head. Avoid using a larger line as it may cut
down the trimming performance.
 WARNING
• 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.
