LINE FEEDING/WINDING
INSTRUCTION
1. Automatic line feed system
When initially switching on the trimmer, a small length of
line is fed out. Each time the tool is started from rest it
will advance about 0.25 inches of trimmer line.
A ‘clattering’ noise will be heard when the lines hit the
Line Cutter. DO NOT BE ALARMED. This is quite normal.
After about 5 seconds the line will be cut to the correct
length and the noise will reduce as the motor gains full
speed.
If the noise of the line being cut can’t be heard, more line
will need to be fed out.
To feed more line, it is first necessary to allow the
trimmer to stop completely; it must come to a complete
rest, then restart, allowing the motor to reach full speed.
Repeat above until you hear the line hitting against the
Line Cutter.
2.
TM
(See Fig. L)
Your trimmer is equipped with a Command Feed System.
For eciently feeding the line, just press the command
feed button while the machine is running until you hear
the ‘clattering’ noise of the line cutting.
The motor will shut off when pressing the Command
Feed button and will restart when releasing the button.
During that process the line will automatically feed
additional line for cutting.
3. Manually feeding the line (See Fig. M)
Turn off the trimmer and remove the battery. If required,
line can be fed out manually. To operate, press and
release manual Line Feed Button, while gently pulling out
the line until it is long enough to reach the Line Cutter. If
the line extends past the Line Cutter, too much line has
been fed out. If too much line is fed out, remove the Spool
Cap and turn Spool counter-clockwise until the line is at
the desired length.
4. Manually winding the line
( See Fig. O1, O2, O3, O4)
Take approximately 10ft (3m) of line. Insert 5/8 inch
(15mm) of line into the Spool holes and wind line in the
direction of the arrows on the top of the Spool. Leave
approximately 4 inches (100mm) of line unwound and
place into the cleat. Ensure that the line is neatly coiled
on the Spool. Failure to do so will impair the eciency of
the automatic line feed. Then fit the Spool as shown in
Fig. N1, N2, N3
5. MAINTENANCE
After use, disconnect the battery from the tool and check
for damage.
Your power tool requires no additional lubrication or
maintenance. There are no user serviceable parts in
your power tool. Never use water or chemical cleaners
to clean your power tool. Wipe clean with a dry cloth.
Always store your power tool in a dry place, and out of
the reach of children. Keep the motor ventilation slots
clean. Keep all working controls free of dust.
For Battery tools
The ambient temperature range for the use and storage
of tool and battery is 0oC-45oC.
The recommended ambient temperature range for the
charging system during charging is 0oC-40oC.
