FREQUENTLY ASKED QUESTIONS

  • Q1: Do I need to mix gas and oil for this trimmer?
  • No. The 4-Cycle engine runs on straight gasoline and has a separate oil reservoir, eliminating the need to mix fuel and oil.

  • The tool is designed with a Split-Shaft System for quick attachment changes. Simply follow the included instructions to swap the bump feed head with the 3-Tooth Blade.
