Иштөө нускамалары
1. Кесүү
Hold the trimmer firmly with both hands. To start, press the safety lock-off button and then squeeze the trigger. Move the trimmer in a sweeping motion, keeping the cutting line parallel to the ground. The Automatic Feed Spool (AFS) system will automatically advance the line as needed, providing uninterrupted performance.

2. Wheeled Edging
To convert the tool to a wheeled edger, simply rotate the shaft. The integrated wheel allows for precise and clean lines along sidewalks and driveways. Guide the wheel along the edge of the surface you wish to trim, maintaining a steady pace.

3. Dual Speed Control
The LST522 features dual speed control. Use the higher speed setting for tougher overgrowth and dense areas, leveraging the PowerDrive Transmission for increased torque. Switch to the lower speed setting for lighter tasks or to extend battery runtime.
