There's a certain satisfaction that comes with tackling overgrown areas, isn't there? And when you've got a STIHL brushcutter like the FS 80 or FS 85, you've got a serious tool for the job. But before you can unleash its power, you've got to get it started. It might seem straightforward, but like anything with an engine, a little know-how goes a long way to making sure it fires up smoothly and safely.
First things first, safety is paramount. STIHL is very clear about this, and for good reason. Before you even think about pulling that starter cord, make sure you've read and understood the instruction manual. It's not just a formality; it's packed with crucial safety precautions that can prevent serious injury. Think of it as your essential pre-flight check for your brushcutter.
Now, let's talk fuel. Your STIHL brushcutter needs the right mix. Generally, this means a blend of gasoline and a specific STIHL two-stroke engine oil. The manual will detail the exact ratio, but it's usually around 50:1. Using the wrong fuel or oil can seriously damage the engine, so always double-check what your model requires. When you're fueling up, do it in a well-ventilated area, away from any open flames or sparks. It’s also a good idea to have a rag handy to wipe up any spills.
With the fuel sorted, let's get to the actual starting sequence. It’s a multi-step process designed for reliability:
-
Ensure the Spark Plug is Dry: If the engine has been flooded, the spark plug might be wet. You can check this by removing it and wiping it dry. If it's significantly wet, you might need to let it air out for a bit.
-
Set the Choke: For a cold engine, you'll want to engage the choke. This enriches the fuel-air mixture, making it easier to start. The choke lever usually has positions for 'cold start' and 'warm start'. For a cold engine, move it to the full choke position.
-
Set the Throttle: You'll typically need to set the throttle to a partially open position. The manual will show you exactly where this is, often indicated by a small mark or a specific lever position.
-
Engage the Ignition: Make sure the ignition switch is in the 'on' or 'run' position.
-
Pull the Starter Rope: Now, firmly and smoothly pull the starter rope. You're looking for the engine to sputter or briefly fire. This is called 'catching'.
-
Disengage the Choke (Partially): Once the engine catches, you'll want to move the choke lever to the 'warm start' or partially open position. This leans out the mixture slightly as the engine warms up.
-
Pull the Starter Rope Again: Give the starter rope another pull. The engine should now start and run.
-
Fully Disengage the Choke: Once the engine is running smoothly, you can fully disengage the choke.
-
Warm Up: Let the engine run for a minute or two at idle to fully warm up before you start cutting. This helps ensure optimal performance and longevity.
If your brushcutter doesn't start after a few pulls, don't keep yanking away endlessly. It's better to stop, re-evaluate, and perhaps consult the manual's troubleshooting section. Over-pulling can sometimes flood the engine or even damage the starter mechanism.
Remember, these are general steps, and your specific STIHL FS 80 or FS 85 model might have slight variations. Always refer to your owner's manual for the most accurate and detailed instructions. It’s your best friend when it comes to keeping your STIHL running strong and safely.
