The Stihl MS 250 chainsaw is a powerful and reliable tool, but proper starting procedures are crucial for safety and optimal performance. Whether you are a seasoned professional or a first-time user, mastering the correct starting process is essential. This guide provides clear and concise instructions to help both technical enthusiasts and beginners successfully start a Stihl MS 250 chainsaw.
Preparation: Safety First
**1. ** Safety Gear: Before starting the chainsaw, ensure you are wearing appropriate safety gear including gloves, safety glasses, hearing protection, and sturdy, non-slip footwear.
**2. ** Check Fuel and Oil Levels: Confirm that there is enough mixed fuel (following the manufacturer’s recommendations) and chain oil in the respective tanks.
Starting the Stihl MS 250 Chainsaw
**1. ** On/Off Switch: Locate the on/off switch and move it to the ‘On’ position. The switch is typically marked with ‘I’ for on and ‘O’ for off.
**2. ** Priming the Engine: Press the primer bulb several times until you see fuel in it. This ensures the carburetor has enough fuel to start the engine.
**3. ** Choke Setting: Set the choke lever to the closed or ‘Choke’ position. This enriches the fuel-air mixture for easier starting.
**4. ** Starting Procedure: Hold the chainsaw on a flat surface. Place your right foot in the rear handle for stability. Use your left hand to firmly grip the front handle and pull the starter handle gently until you feel resistance. Then, give it a quick, strong pull to start the engine.
**5. ** Warm-Up: After the engine starts, let the chainsaw idle for a few moments to warm up. During this time, disengage the choke gradually until the chainsaw runs smoothly.
Important Tips:
**1. ** Avoid Flooding: If the chainsaw doesn’t start after a few pulls, avoid flooding the engine by not priming excessively or pulling the starter cord excessively. Instead, check the choke and fuel supply and try again.
**2. ** Maintenance: Regular maintenance, including cleaning the air filter, checking spark plugs, and ensuring the chain tension, contributes to easier starts and overall chainsaw performance.
**3. ** Shut Down Properly: To turn off the chainsaw, slide the on/off switch to the ‘Off’ position. Allow the engine to cool down before storing the chainsaw.
Starting a Stihl MS 250 chainsaw is a straightforward process when following these steps. Always refer to the user manual for specific instructions related to your particular model. By following the correct procedures and practicing safety measures, you can ensure the reliable and efficient operation of your chainsaw, making your tasks easier and safer.
