Setup and Assembly
1. Charging the Battery
Before first use, fully charge the 20V MAX Lithium Ion battery. Connect the charger to a standard power outlet and insert the battery pack.

2. Attaching the Guard
Align the guard with the slots on the trimmer head and push firmly until it clicks into place. Ensure it is securely fastened before operation. The guard protects the user from debris and the cutting line.
3. Assembling the Shaft and Handle
Insert the upper shaft into the lower shaft until it locks. The trimmer features an adjustable height and handle for ideal user comfort. Loosen the collar to extend or retract the shaft to your desired length, then tighten to secure. Adjust the auxiliary handle position for comfortable grip and balance.

4. Installing the Automatic Feed Spool (AFS)
The trimmer comes with an Automatic Feed Spool (AFS) which automatically feeds trimmer line as needed, eliminating the need for manual bumping. To install or replace the spool, ensure the battery is removed. Press the tabs on the spool cap and remove it. Place the new spool onto the spindle, ensuring the line is threaded through the eyelet. Replace the spool cap, aligning the tabs and pressing until it clicks.

Operating Instructions
1. Trimming Operation
Insert the charged battery pack into the tool until it clicks. To start the trimmer, press the trigger. Hold the trimmer comfortably, keeping the cutting head parallel to the ground. Move the trimmer slowly and steadily across the area to be trimmed. The 10-inch cutting swath allows for efficient coverage.

2. Edging Operation
The LST201 easily converts from a trimmer to an edger. To switch to edging mode, rotate the trimmer head 180 degrees. This allows you to edge along sidewalks and driveways with precision. Guide the wheel along the hard surface to maintain a consistent cutting depth.
