Safety Precautions
Always read the safety manual and wear proper PPE, including gloves, safety glasses, and protective clothing. Understand reactive forces and kickback prevention to ensure safe operation.
2.1 Personal Protective Equipment (PPE)
Wearing proper PPE is essential for safe operation of the STIHL MS 170. This includes gloves, safety glasses, and protective clothing like long sleeves and sturdy pants.
