- Starting: Ensure the battery is installed. Press the safety lock-out button and then squeeze the variable speed trigger to start the trimmer.
- Auto-Feed Head: The trimmer features an auto-feed head that automatically extends the cutting line as needed. Avoid intentionally bumping the head to feed line, as this can lead to excessive line consumption.
