Pull the starter rope – that’s the core of how to start a Stihl chain saw. But doing it right means following a few key steps in order to get your saw running safely and quickly every single time.
I’ve owned Stihl saws for years. I know that first pull can feel tough if you don’t know the drill.
It’s not just about yanking a cord. You need to set up the saw first. This guide will walk you through the whole process.
We’ll cover the cold start, the warm start, and what to do if it just won’t fire up. Let’s get your saw running.
The Right Way to Start Your Stihl Saw
Here’s the deal. There is a proper sequence for how to start a Stihl chain saw. Skipping steps can make it hard or even unsafe.
First, always check your work area. Make sure you have firm footing and nothing in the way. Safety is the most important part of how to start a Stihl chain saw.
Next, look at the saw itself. Is the chain brake on? It should be. The bar and chain should be clear of the ground and any objects.
Now, let’s talk about the controls. You’ll use the master control lever. This one handle does three things. It controls the choke, the throttle, and the stop switch.
For a cold engine, you set it to the choke position. This gives the engine a rich fuel mix to start. It’s a key part of how to start a Stihl chain saw from cold.
Finally, place the saw on a flat, stable surface. Hold it down with your left hand on the front handle. Your right foot can go in the rear handle for extra stability. Now you’re ready to pull.
Step-by-Step Cold Start Procedure
This is how to start a Stihl chain saw that hasn’t been run recently. The engine is completely cold. Follow these steps closely.
First, engage the chain brake by pushing it forward. You should hear a click. This locks the chain so it can’t spin during starting.
Second, find the master control lever. Push it all the way down. This sets the choke to the full “start” position. The throttle also be locked.
Third, press the decompression valve if your saw has one. Many Stihl models have this button. It makes pulling the starter rope much easier.
Now, place your right foot through the rear handle. Press the saw firmly onto the ground. Hold the front handle with your left hand.
With your right hand, pull the starter rope out slowly until you feel resistance. Then give it a strong, fast pull straight up. Do not yank it at an angle.
You should hear the engine try to start or “pop”. Once it pops, move the master control lever up one click to the half-throttle position. Then pull the starter rope again. It should start on this pull.
How to Start a Stihl Chain Saw That’s Warm
The process changes if the engine is already warm. Maybe you just turned it off to move some wood. Here’s how to start a Stihl chain saw that’s still hot.
You do not use the choke on a warm engine. Using choke on a warm saw will flood it with too much fuel. Then it won’t start at all.
Set the master control lever to the half-throttle position. This is the middle setting. The throttle will be slightly engaged but locked.
You still engage the chain brake for safety. Place the saw on the ground and secure it just like before. Your footing is still important.
Now pull the starter rope. It should start within one or two pulls. A warm engine doesn’t need the rich fuel mix from the choke.
If it doesn’t start after three pulls, something might be wrong. Check that the stop switch isn’t on. Also make sure you have fuel in the tank.
Remember, the warm start is simpler. It’s a common mistake to use choke when you shouldn’t. Knowing when not to use choke is part of how to start a Stihl chain saw correctly.
Using the Decompression Valve
Many Stihl saws have a decompression valve. It’s a small button usually near the spark plug. This tool makes starting much easier.
Pressing this valve releases compression in the cylinder. This reduces the force needed to pull the starter rope. It’s a big help, especially on larger saws.
You press it before your first pull on a cold start. Just push it in with your finger. You should feel it click. The valve will pop back out once the engine starts.
Do you need to use it every time? For a cold start, yes. It’s part of the proper sequence for how to start a Stihl chain saw. For a warm start, you usually don’t need it.
The valve is a safety feature too. It helps prevent kickback during starting. According to the Occupational Safety and Health Administration (OSHA), proper starting technique reduces injury risk.
If your saw has one, use it. It makes the job easier on your arm and shoulder. It’s there for a reason.
Common Starting Problems and Fixes
Sometimes the saw just won’t start. Don’t get frustrated. Here are common issues and how to fix them when learning how to start a Stihl chain saw.
First, a flooded engine. This happens if you pull too many times with the choke on. You’ll smell strong gasoline. To fix it, move the control lever to full throttle with no choke. Hold the throttle trigger open and pull the starter rope several times. This clears out the extra fuel.
Second, old fuel. Gas goes bad after about 30 days. It can clog the carburetor. Always use fresh fuel mix. The US Forest Service recommends proper fuel storage for outdoor power equipment.
Third, a dirty air filter. A clogged filter starves the engine of air. Check and clean your filter regularly. A simple tap can clear out dust.
Fourth, a fouled spark plug. Remove it and check the electrode. It should be clean and dry. A wet or black plug needs cleaning or replacement.
Fifth, the chain brake might be stuck on. Make sure it’s fully disengaged before trying to start. Sometimes debris can jam the mechanism.
Work through these checks methodically. Most starting problems have a simple fix. Patience is key when figuring out how to start a Stihl chain saw that’s being stubborn.
Safety Checks Before Every Start
Safety isn’t optional. You must do these checks every single time. They are the first part of how to start a Stihl chain saw.
Check your personal gear first. Are you wearing safety glasses? Do you have hearing protection? Sturdy gloves and cut-resistant pants are a good idea too.
Inspect the saw itself. Look for loose parts or damage. Check that the chain is properly tensioned. It should snap back when you pull it from the bar.
Make sure the bar and chain are clear. They must not be touching the ground, wood, or your body. The chain should spin freely when the brake is off.
Verify the chain brake works. Engage it and try to turn the chain by hand. It should not move. This brake can stop a moving chain in milliseconds.
Check your fuel mix. Is it the right ratio for your saw? Most Stihl saws use a 50:1 mix. Using straight gas will destroy the engine quickly.
Finally, scan your work area. Ensure no people or pets are nearby. Have a clear path to move away once the saw is running. The CDC’s NIOSH reports that proper setup prevents many logging injuries.
Proper Pulling Technique
How you pull matters a lot. Bad technique can hurt you or damage the starter. Let’s break down the right way to pull when you learn how to start a Stihl chain saw.
Grip the starter handle firmly but not too tight. Your knuckles should face up. Do not wrap your fingers around the handle in a death grip.
Pull straight out and up. The rope should follow the path of the starter pulley. Do not pull at an angle to the side.
Use a smooth, fast motion. Do not jerk it. A quick, steady pull works best. Let the rope rewind slowly back into the housing.
Do not let the starter handle snap back. Guide it back with your hand. Letting it snap can damage the starter mechanism over time.
If the engine “pops” but doesn’t run, move the control lever up one notch. Then pull again. This is the transition from choke to half-throttle.
For a warm engine, you might only need a short pull. The goal is to turn the engine over just enough to fire. This is a key skill in how to start a Stihl chain saw efficiently.
After the Engine Starts
You got it running. Great job. But you’re not done yet. Here’s what to do next after you figure out how to start a Stihl chain saw.
First, let the engine idle for a moment. Don’t immediately rev it high. Let it warm up for 15-30 seconds. This allows oil to circulate.
Next, disengage the chain brake. Pull the brake handle back toward you until it clicks. The chain is now free to spin if you give it throttle.
Do a quick test of the chain brake. With the engine idling, tap the brake forward. The chain should stop instantly. This confirms the safety system works.
Check the chain oiler. Hold the saw over a light-colored surface and rev the engine briefly. You should see a line of oil fling off the chain. No oil means a problem.
Now you’re ready to work. But stay aware. Keep both hands on the saw while cutting. Maintain solid footing at all times.
Remember, a running saw is a dangerous tool. Respect it. The process of how to start a Stihl chain saw includes knowing how to handle it once it’s alive.
Maintenance for Easy Starting
A well-maintained saw starts easily. Neglect leads to hard starting. Here’s how to keep your saw ready so you always know how to start a Stihl chain saw quickly.
Use fresh fuel mix. Don’t leave gas in the saw for more than a few weeks. Old fuel gums up the carburetor. Drain the tank if you won’t use it for a while.
Clean the air filter often. A dirty filter chokes the engine. Tap it out or wash it if it’s the foam type. Let it dry completely before reinstalling.
Keep the spark plug clean. Check it every few months. The electrode should be a light tan color. A black, wet, or white plug needs attention.
Lubricate the bar and chain. Use proper bar and chain oil. Check the oil level every time you refuel. A dry chain wears out fast and can break.
Store the saw properly. Keep it in a dry place. Use a bar cover to protect the chain. The Environmental Protection Agency (EPA) has guidelines for small engine storage to prevent pollution.
Do these simple things. Your saw will reward you with reliable starts. Good upkeep is the best way to ensure you always know how to start a Stihl chain saw.
Frequently Asked Questions
How do I start a Stihl chainsaw for the first time?
Follow the cold start procedure exactly. Engage the chain brake, set the master control to choke, and pull. New saws might need a few extra pulls to get fuel into the system.
Why won’t my Stihl chainsaw start?
Check the basics first. Is there fresh fuel? Is the air filter clean? Is the spark plug firing? Most problems come from old gas or a dirty filter. Also, make sure you’re using the right start sequence.
Should the chain brake be on when starting?
Yes, always. The chain brake must be engaged before you pull the starter rope. This is a critical safety step. It prevents the chain from spinning if the engine kicks during starting.
How do I start a Stihl chainsaw after it has been sitting?
It will need a cold start. But first, check the fuel. Old gas is the number one reason a stored saw won’t start. You may need to drain the tank and carburetor and add fresh mix.
What is the decompression valve for?
It reduces engine compression during starting. This makes pulling the starter rope much easier. Press it before your first pull on a cold engine. It pops out automatically when the engine starts.
Can I start my Stihl saw without putting it on the ground?
No, you should not. Stihl specifically recommends starting on the ground with the rear handle secured. Starting in your hands or between your legs is dangerous and can lead to loss of control.
