LINE INSTALLATION
Only use original equipment manufacturer replacement line (up to 0.080 inch (2.03
mm) diameter). Line other than the specified may make the motor overheat or fail.
There are two methods to replace the trimming line:
• Wind the inner reel with new line
• Install a prewound inner reel
Winding the Existing Inner Reel
1. Remove the cutting head cover by pressing in both tabs that are visible on
either side or the cutting head (Fig. 14).
2. Remove the inner reel from the outer spool (Fig. 15).
3. Remove any old line from the inner reel and use a clean cloth to wipe the
inner surface of the outer spool.
NOTE: Use a clean cloth to clean the inner reel, spring, shaft, and inner
surface of the outer spool.
4. Take approximately 12 feet (3.6 m) of new trimming line and insert one end of
the line into the hole at the top of the inner reel (Fig. 16).
5. Wind the line, in even and tight layers, onto the reel (Fig. 16). Wind the line in
the direction indicated on the inner reel.
NOTE: Failure to wind the line in the direction indicated will cause the cutting
head to operate incorrectly.
6. Insert the end of the line into one of the holding slots (Fig. 16).
7. Insert the end of the line through the eyelet in the outer spool (Fig. 15).
8. Place the inner reel inside the outer spool.
9. Hold the inner reel in place, grasp the line end and pull firmly to release the
line from the holding slot in the inner reel.
10. Install the cutting head cover over the inner reel. Align the tabs on the cover
with the slots in the outer spool and press the cover down evenly until it
snaps into place (Fig. 15).
NOTE: Make sure the cutting head cover tabs snap into place or the inner reel
will come out during operation.
Installing a prewound reel
Always use genuine replacement line. Using larger line than specified may make
the motor overheat or fail.
1. Remove the cutting head cover by pressing in on both of the cutting head
cover tabs that are visible on either side of the outer spool (Fig. 14).
2. Remove the old inner reel from the outer spool.
3. Use a clean cloth to wipe the inner surface of the outer spool.
4. Insert the end of the line of the pre-wound reel through the eyelet in the outer spool (Fig. 15).
5. Place the inner reel inside the outer spool (Fig. 15).
6. Hold the inner reel in place, grasp the line end and pull firmly to release the line from the holding slot in the inner reel.
7. Install the cutting head cover over the inner reel. Align the tabs on the cover with the slots in the outer spool and press the cover down
evenly until it snaps into place.
NOTE: Make sure the cutting head cover tabs snap into place or the inner reel will come out during operation.
CHARGER MAINTENANCE
• Keep the charger clean and clear of debris. Do not allow foreign material into the recessed cavity or on the contacts.
• Wipe with a dry cloth. Do not use solvents, water or place in wet conditions.
• Always unplug the charger when not in use.
• The battery pack may be stored in the charger. However, it is recommended to disconnect the charger from the power source.
• To ensure safety and reliability, all repairs should be performed by a qualified service technician.
• Check that the charger contacts have not been shorted by debris or foreign material.
• Keep the charger and battery pack in an area that is between 65 and 75˚ F (18 and 24˚ C).
ENVIRONMENTALLY SAFE BATTERY DISPOSAL
To avoid damage to the environment:
• DO NOT attempt to remove or destroy any of the battery pack components.
• DO NOT attempt to open the battery pack.
• DO NOT place the battery pack in the regular household trash.
• DO NOT incinerate.

ADJUSTING THE TRIMMER LINE
The trimmer line wears down and becomes shorter with use. This unit is equipped with an Automatic Line Advancement cutting head. Line
is automatically extended each time the motor starts.
If the line becomes too short:
1. Stop the motor. See Starting and Stopping Instructions.
2. Wait two seconds and then restart the motor.
3. Repeat this process until the line length reaches the line cutting blade on the cutting head shield.
If the line does not automatically advance, the trimming line may be tangled or empty. Refer to the Maintenance section of this manual.
NOTE: DO NOT bump the cutting head; this will damage the unit and void the
warranty.
The trimming line can also be extended manually by lightly pressing the manual
line release button (Fig. 14) and pulling the trimming line. When doing so, always
make sure the motor is off and the battery is removed from the unit.
The life of your cutting line is dependent upon:
• Following the trimming techniques previously explained
• What vegetation is cut
• Where the vegetation is cut.
For example, the line will wear faster when trimming against a foundation wall as
opposed to trimming around a tree.
Decorative Trimming
Decorative trimming is the act of removing all vegetation from around trees,
posts, fences, etc. To accomplish it, rotate the whole unit so that the cutting
attachment is at a 30˚ angle to the ground (Fig. 13).
