4.1 Chain Tension Adjustment
Proper chain tension is critical for safe and efficient cutting. Use a screwdriver to adjust the tensioning screw, ensuring the chain sits evenly on the guide bar.

Proper care extends the life of both the bar and chain, ensuring smooth cutting and safety.
4.3 Cleaning the Air Filter
Cleaning the air filter regularly is essential for maintaining your Stihl MS 170 chainsaw’s performance. Locate the filter, typically near the carburetor. Gently remove dust with compressed air or tap it clean. For foam filters, wash with mild soap and water, then dry thoroughly before reinstalling. Avoid using damaged filters or operating without one to prevent engine damage. Clean or replace the filter as needed, especially after use in dusty conditions, to ensure optimal airflow and engine efficiency.
