To start the Stihl MS 441, engage the chain brake, set the master control lever to the choke position, pull the starter rope until the engine fires, then move the lever to the half-throttle position and pull again to start.
Check the fuel level and condition, inspect the spark plug for wear or carbon build-up, ensure the air filter is clean, and verify the ignition coil is functioning.
Regular maintenance includes cleaning the air filter, checking and sharpening the chain, inspecting the guide bar, checking the chain tension, and inspecting the spark plug.
Adjust the carburetor by locating the L (low), H (high), and LA (idle speed) screws. Fine-tune the screws while the engine is running to achieve optimal performance. Refer to the user manual for specific adjustment procedures.
Overheating can result from a dirty air filter, improper fuel mixture, or insufficient oil in the fuel. Check and clean the air filter, ensure the fuel mixture is correct, and verify proper oil levels.
Use a round file that matches the chain's pitch, maintain the correct filing angle, and ensure even sharpening across all teeth. It's recommended to use a file guide for accuracy.
The correct fuel mixture for the Stihl MS 441 is 50:1, which means 50 parts gasoline to 1 part two-stroke engine oil.
To replace the spark plug, remove the top cover, disconnect the spark plug boot, use a spark plug wrench to remove the old plug, and install a new plug with the correct gap setting.
Symptoms include reduced engine power, increased fuel consumption, difficulty starting, and rough idling. Check and clean the air filter regularly to prevent clogging.
Regularly inspect the guide bar for wear and damage, clean the bar groove, and ensure the lubrication holes are clear. Rotate the bar periodically to ensure even wear.
