   Advancing the Line Manually  (page 12).
   

Advancing the Line Manually

Remove the battery pack from the trimmer, then push the bump button at the base of the spool retainer while pulling on the trimmer line to manually advance the line.

Operating Tips

• Keep the trimmer tilted toward the area being cut; this is the best cutting area.
• The string trimmer cuts when you move it from left to right. This prevents the trimmer from throwing debris at you.
• Use the tip of the string to do the cutting; do not force the string head into uncut grass.
• Wire and picket fences can cause the string to wear rapidly and even break. Stone and brick walls, curbs, and wood can also cause the string to wear rapidly.
• Avoid trees and shrubs. The string can easily damage tree bark, wood moldings, siding, and fence posts.
  

Replacing the Spool

Use only 2 mm (0.08 inch) diameter monofilament string.
Important: Using a larger diameter string causes the motor to overheat and fail.

1. Remove the battery.

2. Push in the tab on the side of the spool retainer (Figure 13).
   

3. Pull the spool retainer up to remove it and remove the spool.

4. To install the new spool, make sure that the string is captured in 1 of the remaining slots on the new spool. Make sure the end of the string extends approximately 150 mm (6  inches). 5. Install the new spool so that the string aligns with the eyelet in the string head. Thread the string into the eyelet.

5. Pull the string extending from the string head so that the string releases from the slot in the spool.

6. Install the spool retainer by pressing the tabs into the slots and pushing down until the spool retainer clicks into place.

Replacing the String

1. Remove the battery.

2. Remove the spool; refer to Replacing the Spool (page 13).
   
   Note: Remove any old string remaining on the spool.

3. Each side of the spool accepts approximately 2.5 m (8 ft) of string. Use only 2 mm (0.08 inch) diameter monofilament string.
   Note: Do not use any other gauge or type of string, as this could damage the trimmer.

4. Insert the string into the anchor slot in the upper part of the spool (Figure 14). Wind the string onto the spool in the direction shown by the arrows on the spool.

5. Place the string in the slot on the upper spool flange, leaving about 150 mm (6 inches) extended beyond the slot.
   Note: Do not overfill. After winding the string, there should be at least 6 mm (1/4 inch) between the wound string and the outside edge of the spool.

6. Replace the spool and the spool retainer; refer to Replacing the Spool (page 13).

Replacing the Blade

1. Press the lock shaft button and turn the spool counterclockwise until it is removed.
2. Take out the brush breaker blade from the accessory package and remove the brush breaker sheath.
3. Insert the blade into the brushless motor assembly, cover the blade pressing plate and cover the blade pressing cover.
