Proper Operation
Safety First: Always wear appropriate safety gear, including a helmet with a face shield, hearing protection, gloves, and safety chaps when operating the MS 311.
Fuel Mixture: Use a high-quality, 50:1 gasoline-to-oil ratio with a Stihl two-stroke engine oil. Mixing it accurately is essential for engine longevity and optimal performance.
Starting the Chainsaw: To start the MS 311, engage the chain brake, set the master control lever to the cold start position, and pull the starter handle slowly until you feel resistance. Then, give it a brisk pull. Once it starts, release the throttle trigger and let the chainsaw warm up.
Chain Tension: Proper chain tension is vital for safe and efficient operation. Check the tension regularly and adjust it as needed. The chain should be snug against the guide bar without sagging.
Cutting Techniques: Always cut at full throttle, using a smooth and steady motion. Ensure that the chain contacts the wood using the full length of the guide bar to prevent kickback.
Maintenance
Chain Sharpening: Keep the chain sharp for efficient cutting. Use a round file and a file guide to maintain the correct chain tooth angles and depths.
Air Filter: Regularly clean and inspect the air filter. Replace it if it’s damaged or excessively dirty to ensure proper engine ventilation.
Spark Plug: Check the spark plug regularly and replace it if it’s fouled or damaged. Use the specified Stihl spark plug for optimal performance.
Chain Lubrication: Ensure the chain receives proper lubrication by checking the oil level in the chain oil tank. Clean the oil ports and grooves regularly.
Fuel System Care: Use fresh fuel, and consider using a fuel stabilizer if the chainsaw will be stored for an extended period. Properly dispose of old fuel.
