USING THE LINE TRIMMER
Clear the area to be cut before each use. Remove all objects, such as rocks, broken glass, nails, wire, or lines that can be thrown or become entangled in the cutting attachment. Clear the area of children, bystanders, and pets. At a minimum, keep all children, bystanders, and pets at least 15m away; there still may be a risk to bystanders from thrown objects. Bystanders should be encouraged to wear eye protection. If you are approached, stop the motor and cutting attachment immediately.
Before each use, check for damage/worn parts
Check the bump head, guard, and front-assist handle and replace the parts that are cracked, warped, bent, or damaged in any way.
The line-cutting blade on the edge of the guard can dull over time. It is recommended that you periodically sharpen it with a file or replace it with a new blade.
After each use, clean the trimmer.
ADJUSTING CUTTING LINE LENGTH
The trimmer head allows the operator to release more cutting lines without stopping the motor. As the line becomes frayed or worn, the additional line can be released by lightly tapping the trimmer head on the ground while operating the trimmer (Fig. M).
NOTICE: Line release will require multiple tapping as the cutting line becomes shorter.
WARNING: Do not remove or alter the line cutting blade assembly. Excessive line length will cause the motor to overheat and may result in serious personal injury.
LINE REPLACEMENT
NOTICE: Always use the recommended nylon cutting line with a diameter that does not exceed 2.4 mm. Using lines other than that specified may cause the line trimmer to overheat or become damaged.
WARNING: Never use metal-reinforced line, wire, or rope, etc. These can break off and become dangerous projectiles.

1. Remove the battery pack.
2. Remove the remaining cutting line, if necessary.
3. Cut 4 m of cutting line. Insert the line into the mounting hole inside the eyelet (Fig. O). Push and pull the line from the other side until equal amounts of the line appear on both sides of the spool.
4. Install the battery pack onto the string trimmer.
5. Press and hold the line-loading button to start the line-winding motor. The line will be wound into the trimmer head continuously (Fig. P).
6. Watch the remaining line length carefully. Briefly press the line loading button to adjust the length until 13 cm of the line is shown on each side.
7. Push down on the trimmer head while pulling on the lines to manually advance the line in order to check for proper assembly of the cutting line.

When the cutting line breaks from the line outlet or the cutting line is not released when the trimmer head is tapped, follow the steps below

1. Remove the battery pack from the trimmer.
2. Press the release tabs on the trimmer head and remove the lower cover assembly by pulling it straight out (Fig. Q).
3. Remove the cutting line from the spool. 4. Insert the spring into the slot in the lower cover assembly (Fig. R).
4. With one hand holding the trimmer, use another hand to grasp the lower cover assembly and align the slots in the lower cover assembly with the release tabs. Press the lower cover assembly until it snaps into place, at which time you will hear a distinct click sound (Fig. S).
5. Follow the instructions in the “LINE REPLACEMENT” section to reload the cutting line.

TRIMMER HEAD REPLACEMENT
WARNING: If the head loosens after it is fixed in position, replace it immediately. Never use a trimmer with a loose cutting attachment.
