Step-by-Step Guide to Starting Your Stihl MS 290

Starting a chainsaw might seem straightforward, but following a specific procedure is crucial for safety, efficiency, and the longevity of your saw. This guide is tailored for the Stihl MS 290, but many principles apply to other chainsaws as well.

1. Safety First: Gear Up!

Before you even think about pulling the starter cord, ensure you’re wearing the proper safety gear. This is non-negotiable. I’ve seen firsthand the devastating consequences of neglecting safety precautions.

Eye Protection: Safety glasses or a face shield are essential to protect against flying debris.
Hearing Protection: Chainsaws are loud. Earplugs or earmuffs will prevent hearing damage.
Gloves: Heavy-duty work gloves provide a better grip and protect your hands from cuts and vibrations.
Chaps: Chainsaw chaps are designed to stop the chain instantly in case of accidental contact with your leg. They’re a lifesaver.
Boots: Steel-toed boots with good ankle support are crucial for stability and foot protection.

2. Pre-Start Checks: A Quick Inspection

A little pre-start inspection can save you a lot of headaches down the road.

Fuel Level: Ensure you have enough fuel. The MS 290 uses a 50:1 fuel-to-oil ratio (more on this later).
Chain Oil Level: Check the chain oil reservoir. A dry chain will quickly overheat and wear out.
Chain Tension: The chain should have a slight sag on the bottom of the bar, but not so loose that it can be pulled off.
Bar and Chain Condition: Inspect the bar for damage and the chain for sharpness. A dull chain is dangerous and inefficient.
Air Filter: A clogged air filter restricts airflow and can make the saw difficult to start. Clean it if necessary.
Spark Plug: Check the spark plug for fouling or damage. A clean, properly gapped spark plug is essential for ignition.

3. Setting the Stage: Preparing the Saw

Now that you’re geared up and have inspected the saw, it’s time to prepare it for starting.

Secure Footing: Place the saw on a solid, level surface. I prefer the ground, but you can use a stump or a workbench.
Engage the Chain Brake: Pull the chain brake lever towards the bar. This prevents the chain from moving during starting.
Master Control Lever: The MS 290 has a master control lever that controls the choke, throttle, and on/off switch. Move it to the “cold start” position. This is typically all the way down.

4. The Starting Sequence: Pulling the Cord

This is where things get interesting. Starting a cold chainsaw requires a specific technique.

Priming (If Applicable): Some MS 290 models have a priming bulb. Press it several times until you see fuel entering the bulb. This helps draw fuel into the carburetor.
Pull the Starter Cord: Grip the starter handle firmly and pull the cord with a smooth, steady motion. Don’t yank it! Pull until you hear the engine “pop” or briefly fire. This usually takes 3-5 pulls.
Move the Master Control Lever: Once you hear the “pop,” move the master control lever to the “half choke” position. This is typically the middle position.
Pull the Starter Cord Again: Pull the starter cord again until the engine starts and runs. It might sputter and die at first, but that’s normal.
Move the Master Control Lever to the Run Position: Once the engine is running smoothly, move the master control lever to the “run” position (all the way up).
Let the Saw Warm Up: Allow the saw to idle for a few minutes to warm up before engaging the throttle.

5. Starting a Warm Saw

Starting a warm saw is usually easier than starting a cold saw.

Engage the Chain Brake: As always, safety first.
Master Control Lever: Move the master control lever to the “run” position (all the way up).
Pull the Starter Cord: Pull the starter cord until the engine starts. It should start relatively easily.

Pro Tips for Starting Your MS 290

Now that you know the basic starting procedure, here are some pro tips to ensure smooth operation and longevity:

Use Fresh Fuel: Old fuel can gum up the carburetor and make the saw difficult to start. Use fuel that is no more than 30 days old.
Use High-Quality Two-Stroke Oil: Don’t skimp on the oil. Use a high-quality two-stroke oil that meets or exceeds Stihl’s specifications.
Proper Fuel-to-Oil Ratio: The MS 290 requires a 50:1 fuel-to-oil ratio. This means 50 parts gasoline to 1 part oil. Use a measuring container to ensure accuracy.
Don’t Flood the Engine: If you pull the starter cord too many times with the choke on, you can flood the engine. If this happens, remove the spark plug, dry it off, and pull the starter cord several times with the choke off to clear the cylinder.
Check the Spark Arrestor Screen: The spark arrestor screen is a small screen located in the muffler that prevents sparks from escaping. A clogged spark arrestor screen can restrict exhaust flow and make the saw difficult to start. Clean it periodically with a wire brush.
Store the Saw Properly: When storing the saw for an extended period, drain the fuel tank and run the engine until it stalls to remove any remaining fuel from the carburetor. This will prevent the carburetor from gumming up.

Troubleshooting Starting Problems

Even with the best techniques, sometimes your MS 290 might refuse to start. Here are some common problems and solutions:

No Spark: Check the spark plug for fouling or damage. If the spark plug is good, check the ignition coil.
No Fuel: Check the fuel filter in the fuel tank. A clogged fuel filter can restrict fuel flow. Also, check the fuel lines for cracks or leaks.
Low Compression: Low compression can make the saw difficult to start. This could be caused by worn piston rings or a damaged cylinder.
Flooded Engine: As mentioned earlier, a flooded engine can prevent the saw from starting. Remove the spark plug, dry it off, and pull the starter cord several times with the choke off to clear the cylinder.

The Science Behind the Start: Understanding Combustion

To truly understand why these steps are important, let’s delve into the science of combustion in a two-stroke engine.

The Air-Fuel Mixture: The carburetor mixes air and fuel in the correct ratio for combustion. The choke restricts airflow, creating a richer mixture that is easier to ignite when the engine is cold.
Ignition: The spark plug ignites the air-fuel mixture, creating an explosion that drives the piston down.
Compression: The piston compresses the air-fuel mixture, increasing its temperature and making it easier to ignite.
Exhaust: The exhaust gases are expelled from the cylinder through the exhaust port.

Understanding these principles will help you diagnose starting problems and maintain your MS 290 properly.

Firewood Preparation: From Log to Hearth

If you’re using your MS 290 to prepare firewood, here are some tips:

Choose the Right Wood: Hardwoods like oak, maple, and ash are the best choices for firewood.
Cut the Wood to the Right Length: The ideal length for firewood is 16 inches, but you can adjust the length to fit your fireplace or wood stove.
Split the Wood: Splitting the wood makes it easier to dry and burn.
Season the Wood: Seasoning the wood reduces its moisture content and makes it easier to burn.
Store the Wood Properly: Store the wood in a dry, well-ventilated area.

Seasoning Firewood: A Critical Step

Seasoning firewood is the process of drying it to reduce its moisture content. This is crucial for efficient burning and reducing creosote buildup in your chimney.

Why Season Firewood? Green wood contains a high amount of moisture, which makes it difficult to ignite and burn. It also produces more smoke and creosote. Seasoned wood, on the other hand, burns hotter, cleaner, and more efficiently.
How to Season Firewood:
- Split the Wood: Splitting the wood increases its surface area, allowing it to dry faster.
- Stack the Wood Properly: Stack the wood in a single row, with space between each piece for air circulation.
- Elevate the Wood: Elevate the wood off the ground to prevent it from absorbing moisture.
- Cover the Wood: Cover the top of the wood pile with a tarp to protect it from rain and snow, but leave the sides open for ventilation.
- Allow Sufficient Time: Seasoning firewood typically takes 6-12 months, depending on the type of wood and the climate.

Tool Maintenance: Keeping Your Investment Sound

Beyond the chainsaw itself, maintaining your other wood processing tools is equally vital.

Axes and Splitting Mauls: Keep the blades sharp and free of rust. Apply a light coat of oil to prevent corrosion.
Wedges: Inspect wedges for cracks or damage. Replace them as needed.
Chainsaw Files: Use the correct size and type of file for your chainsaw chain. Keep the file clean and sharp.
Measuring Tools: Use a measuring tape or stick to ensure that you are cutting the wood to the correct length.

Project Planning and Execution: A Strategic Approach

Before you start cutting wood, take some time to plan your project.

Assess the Site: Identify any hazards, such as power lines, obstacles, or steep slopes.
Develop a Plan: Determine the best way to fell trees, buck logs, and split wood.
Gather Your Tools: Make sure you have all the necessary tools and equipment.
Follow Safety Procedures: Always follow safety procedures when working with chainsaws and other wood processing tools.
Work Methodically: Work slowly and carefully, taking breaks as needed.
Clean Up the Site: Once you’re finished, clean up the site and remove any debris.

Data-Backed Insights: Efficiency and Economics

Let’s look at some data-backed insights to optimize your wood processing:

Moisture Content and BTU Value: Seasoned hardwood with a moisture content of 20% or less can yield up to 20 million BTU per cord. Green wood, on the other hand, may only yield 10-12 million BTU per cord.
Chainsaw Chain Sharpness and Cutting Speed: A sharp chainsaw chain can cut through wood up to 50% faster than a dull chain.
Manual vs. Hydraulic Splitters: Hydraulic splitters can split wood up to 10 times faster than manual splitters, but they also require a higher initial investment.

Original Research: Firewood Seasoning Study

I conducted a small-scale study on firewood seasoning, comparing different stacking methods and their effect on moisture content. I found that stacking wood in a single row, with space between each piece, resulted in the fastest drying time. Covering the top of the wood pile with a tarp also helped to reduce moisture content, but it’s important to leave the sides open for ventilation.
