To start the Jonsered CS2250S II Chainsaw, first ensure the chain brake is engaged. Set the master control lever to the choke position. Pull the starter handle until the engine fires, then push the choke in and continue pulling until the engine runs. Release the chain brake and pull the throttle trigger to start cutting.
The correct fuel mixture for the Jonsered CS2250S II Chainsaw is 50:1, which means 2.6 ounces of two-stroke oil per gallon of gasoline. Always use fresh, unleaded gasoline with a minimum octane rating of 89.
To tension the chain, first, loosen the bar nuts slightly. Use the chain tensioning screw to adjust the chain tension, ensuring it has no slack on the underside of the bar but can still be moved by hand. Retighten the bar nuts to secure the bar.
If the chainsaw won’t start, check the fuel level and ensure the choke is set correctly. Inspect the spark plug for wear or damage and replace if necessary. Ensure the air filter is clean and not clogged. Finally, verify that the chain brake is not engaged while starting.
The air filter should be checked and cleaned after every 5 hours of operation or more frequently if used in dusty conditions. A clean air filter ensures optimal engine performance and longevity.
To sharpen the chain, secure the chainsaw and use a round file that matches the chain's pitch. File each cutter with an even number of strokes, maintaining the correct angle. Ensure all cutters are sharpened equally to maintain balance.
After each use, clean the chainsaw of sawdust and debris, check the chain tension and condition, inspect the bar for damage, and ensure all nuts and bolts are tight. Also, check the fuel and oil levels for the next use.
A chain that keeps coming off may be due to incorrect tension, worn sprocket, or incompatible chain and bar. Ensure the chain is properly tensioned and inspect the bar and sprocket for wear. Replace any worn or damaged components.
Always wear protective gear, including gloves, goggles, and hearing protection. Ensure the work area is clear of obstacles and bystanders. Keep a firm grip on the chainsaw and maintain a stable stance. Never operate the chainsaw above shoulder height.
Regular maintenance, including cleaning, timely replacement of worn parts, and proper storage, will extend the life of your chainsaw. Use high-quality fuel and oil, and follow the manufacturer's recommendations for use and care.
