How To Start A Stihl Weed Eater Fs 70 R

Alright, folks, let's talk weed whackers. Specifically, the Stihl FS 70 R. Now, I know what you're thinking: "Ugh, lawn care." But hear me out! Think of it less as a chore and more as… giving your lawn a haircut. A really bad haircut performed by a caffeinated chimpanzee. Okay, maybe not that bad, but you get the picture. It's gotta be done, and the Stihl FS 70 R is a trusty steed in this grassy gladiator battle. But first, you gotta get the darn thing started!

Starting a weed eater can be like trying to convince a toddler to eat their vegetables. Sometimes it's easy, sometimes it's a screaming match. But fear not! We're going to break it down into steps so simple, even your Uncle Barry (the one who wears socks with sandals) can manage it.

Before You Even Think About Pulling the Cord

Before we dive in, let's cover the pre-flight checklist. Think of it like preparing for a mission… a mission to conquer unruly weeds.

Safety First, Sparky!

Seriously. We don't want any ER visits. I'm talking about you, Gary, who once tried to trim the hedges in flip-flops. Wear safety glasses. Flying debris is no joke. Imagine getting a rogue pebble in your eye. Not fun. Also, ear protection is a good idea. These things can be loud, like your neighbor's karaoke night, but hopefully less off-key. Wear sturdy shoes or boots. No sandals or barefoot lawn care, please. Long pants are preferable, too. Basically, dress like you're going into battle against a legion of dandelions.

Fueling Up: Giving Your Beast a Drink

This bad boy runs on a gasoline and oil mixture. Check your owner's manual for the correct ratio. Usually, it's 50:1, but don't just guess! Getting the mixture wrong is like putting sugar in your car's gas tank. Bad news. Use a proper fuel container, and mix the fuel in a well-ventilated area. Spilling fuel is messy and can damage surfaces, not to mention it's a fire hazard. Don't be that neighbor whose garage mysteriously burns down because they were too lazy to mix fuel properly.

Important: Use fresh fuel. Gasoline can go stale, like that bag of chips you found behind the couch. Old fuel can cause starting problems and performance issues. If your fuel has been sitting around for a while (more than a month), it's best to drain it and use fresh stuff. Trust me, your weed eater will thank you.

Checking the Spark Plug: The Tiny Ignition Key

The spark plug is like the tiny spark that starts the whole combustion party. If it's dirty or fouled, your engine won't start, period. To check it, you'll need to remove it. Usually, you can use a spark plug wrench. Examine the electrode. If it's black and gunked up, you can try cleaning it with a wire brush. If it's cracked or damaged, replace it. A new spark plug is cheap insurance against starting headaches.

The Actual Starting Procedure: The Moment of Truth

Okay, deep breaths. You've prepped, you're ready. Now it's time to wrestle this thing to life. Remember, patience is key. It's like trying to teach a cat to fetch. It might take a few tries.

Step 1: The Primer Bulb: Giving It a Little Nudge

The primer bulb is a small, clear bubble usually located near the carburetor. Press it firmly several times (usually 5-10 times) until you see fuel flowing through it. This primes the carburetor with fuel, making it easier to start. Think of it as giving the engine a little pep talk, like "C'mon, you got this!" Don't over-prime it, though. Too much fuel can flood the engine, making it even harder to start.

Step 2: The Choke: Controlling the Airflow

The choke controls the amount of air that enters the engine. When the engine is cold, you'll usually want to set the choke to the "full choke" position. This restricts the airflow, creating a richer fuel mixture that's easier to ignite. Once the engine starts, you'll need to gradually open the choke (move it to the "half choke" or "run" position) as the engine warms up. It's like adjusting the blankets on your bed – too much or too little, and you're uncomfortable.

Find the choke lever! It is usually marked with a picture showing the choke open or closed.

Step 3: The On/Off Switch: Making Sure It's Ready to Rumble

Ensure the on/off switch is in the "on" position. It's usually marked with an "I" or "O" symbol. If it's in the "off" position, you can pull the cord until you're blue in the face, and it won't start. It's like trying to drive a car with the parking brake on. Pointless.

Step 4: Pulling the Starter Cord: The Arm Workout You Didn't Ask For

This is where the fun (or frustration) begins. Hold the weed eater firmly on the ground with one hand. With your other hand, grasp the starter cord handle. Pull the cord slowly until you feel resistance. This engages the starter mechanism. Now, give it a sharp, firm pull. Don't yank it like you're trying to start a lawnmower in Siberia. A smooth, controlled pull is more effective. Repeat this several times until the engine sputters or starts.

Important: Don't pull the cord all the way out! This can damage the starter mechanism. Let the cord retract slowly after each pull. It's like playing tug-of-war – you don't want to pull so hard that you fall on your butt.

Step 5: Adjusting the Choke: Finding the Sweet Spot

Once the engine sputters or starts, immediately move the choke to the "half choke" or "run" position. If the engine dies, move the choke back to the "full choke" position and try again. It may take a few adjustments to find the sweet spot where the engine runs smoothly. It's like finding the perfect temperature setting in your shower – too hot, too cold, just right!

Step 6: Letting It Warm Up: Like a Morning Stretch

Let the engine warm up for a minute or two before you start trimming. This allows the engine to reach its operating temperature and ensures smoother performance. It's like letting your car warm up on a cold morning – it's just good practice.

Troubleshooting: When Things Go Wrong (and They Will)

Sometimes, despite your best efforts, the weed eater just won't start. Don't panic! It happens. Here are a few common problems and solutions:

• Engine won't start at all: Check the fuel level, spark plug, on/off switch, and choke position. Make sure you're using fresh fuel.
• Engine starts but dies immediately: The choke may be in the wrong position. Try adjusting it. Also, check the fuel filter to make sure it's not clogged.
• Engine runs rough or sputters: The spark plug may be fouled. Clean or replace it. Also, check the air filter to make sure it's clean.
• Engine is hard to pull: The spark plug may be fouled, and the cylinder is filled with gas. Remove the spark plug, ground the spark plug wire, and pull the starter cord 10-12 times to expel the fuel from the cylinder. Reinstall the spark plug and try starting again.

If you've tried all these troubleshooting steps and the weed eater still won't start, it's time to consult a professional. Don't be afraid to take it to a qualified repair shop. Sometimes, it's just not worth the headache. Think of it as taking your car to the mechanic when you can't figure out what's wrong.

Tips for Easier Starting: Become a Weed-Whacking Pro

Here are a few extra tips to make starting your Stihl FS 70 R a little easier:

• Store your weed eater properly: When you're not using it, store it in a cool, dry place. Drain the fuel tank before storing it for long periods.
• Use fuel stabilizer: Add fuel stabilizer to the fuel tank to prevent the fuel from going stale.
• Replace the spark plug regularly: A fresh spark plug can make a big difference in starting performance.
• Keep the air filter clean: A dirty air filter can restrict airflow and make the engine harder to start.
• Maintain your weed eater: Regular maintenance, such as cleaning the air filter and replacing the spark plug, can help prevent starting problems.

The Joy of a Well-Trimmed Lawn: It's All Worth It

Starting a weed eater can be a bit of a challenge, but with a little practice and patience, you'll get the hang of it. And once you do, you'll be rewarded with a beautifully trimmed lawn that will make your neighbors jealous (or at least slightly impressed). Think of it as a personal victory – a small but significant accomplishment in the ongoing battle against the forces of nature. And who knows, maybe you'll even start to enjoy it… okay, maybe not enjoy it, but at least tolerate it. Good luck, and happy weed whacking!

Remember that safety is paramount. Always wear the appropriate safety gear, read the owner's manual, and follow all safety precautions. And if you're ever unsure about something, don't hesitate to ask a professional. Now go forth and conquer those weeds!

Now go forth and make your yard the envy of the neighborhood (or at least not the laughingstock). You got this!
