The Stihl 021 chainsaw was manufactured and produced during the period from the late 1980s through the early 2000s.

The Stihl 021 chainsaw typically requires a round file with a diameter of 5/32 inch (4.0 mm) for sharpening its chain. Proper and regular sharpening using the correct file size helps maintain the cutting efficiency and performance of the chainsaw, ensuring smooth and effective cutting through wood. Always refer to the manufacturer's guidelines or your chainsaw's manual to ensure you are using the appropriate file size for optimal results and safety.

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.

Adjusting the carburetor on a STIHL 021 chainsaw involves fine-tuning the fuel-to-air mixture for optimal performance. To do so: 1. Warm up the engine. 2. Locate the three carburetor adjustment screws: L (low), H (high), and LA (idle). 3. Turn the L and H screws clockwise until snug, then back out 1 to 1.5 turns. 4. Start the saw and let it idle. 5. Turn the LA screw to achieve a smooth idle. 6. Accelerate the engine and adjust H screw for peak power. 7. Fine-tune L screw for smooth idling and quick acceleration. Achieving the right balance ensures efficient cutting and prevents engine damage.

The high-speed (H) adjustment screw on the STIHL 021 chainsaw is located near the carburetor. To find it: 1. Locate the carburetor housing, usually near the top or side of the engine. 2. Look for three small screws on the carburetor body. The high-speed screw is typically labeled H. 3. Gently turn the H screw clockwise until it stops, being careful not to overtighten. 4. Gradually turn it counterclockwise 1 to 1.5 turns to start with a baseline setting. The H screw controls the chainsaw's high-speed fuel mixture. Adjust it for optimal performance and smooth operation during high-load cutting tasks.
