LINE REPLACEMENT
WARNING:
Never use metal-reinforced line,
wire, or rope, etc. These can break off and become
dangerous projectiles.
WARNING:
Always use the recommended
nylon cutting line with a diameter of 2.4 mm. Using
line other than that specified may cause the tool to
overheat or become damaged.
The grass trimmer is equipped with an advanced
POWERLOADTM system. The cutting line can be wound
onto the spool simply by pressing a single button. Loading
a full spool can usually be completed in 12 seconds.
Avoid repeated operation of the winding system in
rapid succession to reduce the possibility of motor
damage.
1. Remove the battery pack from the trimmer.
2. Cut one piece of cutting line 4 m long.
3. Insert the line into the eyelet (Fig. R) and push
the line until the end of the line comes out of the
opposite eyelet.
NOTICE:
It is not necessary to align the eyelets in order
to insert the cutting line. If the line cannot be inserted into
the eyelet, mount the battery pack onto the trimmer, then
press the POWERLOAD button briefly to reset the winding
mechanism.
4. Remove the battery pack if it has been mounted onto
the trimmer in step 3.
5. Pull the line from the other side until equal lengths
of the line appear on both sides of the trimmer head
(Fig. S).
6. Install the battery pack onto the grass trimmer.
7. Press and hold the POWERLOAD button to start the
line-winding motor. The line will be wound into the
trimmer head continuously (Fig. T).
8. Watch the remaining line length carefully. Prepare
to release the button as soon as approximately 22
cm of line are left on each side. Briefly press the line
loading button to adjust the length until 18 cm of the
line is showing on each side.
NOTICE:
In case the line is pulled into the trimmer head
by accident, open the head and pull the cutting line
out from the spool. Follow the section
“RELOAD THE
CUTTING LINE”
in this manual to reload the line.
