Cleaning the oiler on a Stihl 021 chainsaw is essential to ensure proper lubrication for the chain and guide bar. To clean the oiler, follow these steps:
1. Disconnect the spark plug to prevent accidental starting.
2. Remove the guide bar and chain.
3. Locate the oiler port on the saw's body.
4. Use a small brush or compressed air to remove debris and buildup from the oiler port.
5. Check the oiler hole for blockages and clean as needed.
6. Reassemble the guide bar, chain, and other components.
Regular oiler cleaning helps maintain smooth chain operation and prolongs the chainsaw's life.
