Maintenance

- Cleaning: After each use, clean the mower deck and trimmer head of grass clippings and debris using a brush or cloth. Do not use water directly on electrical components.
- Mower Blade: Periodically inspect the mower blade for sharpness and damage. A dull or damaged blade should be sharpened or replaced by a qualified service technician.
- Trimmer Line: The trimmer features an auto-feed system. If the line does not advance, refer to the specific trimmer manual for instructions on manually advancing or replacing the line. Use only 0.065” diameter replacement line.
- Battery Care: Store batteries in a cool, dry place away from direct sunlight. Charge batteries fully before storage and every 3-6 months during extended storage to maintain battery health.
