Using the Shrubber Blade
The shrubber blade is suitable for shaping and trimming small hedges, bushes, and ornamental plants. The tool has a cut capacity of 5/16 inches.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your tool. Always disconnect the battery pack before performing any maintenance.
