These trends highlight the importance of having reliable and efficient tools for wood processing. A well-maintained Stihl 046 can be a valuable asset, but only if you know what to look for.

Understanding the Stihl 046’s Legacy

The Stihl 046, also known as the Magnum, is a professional-grade chainsaw renowned for its power and durability. It was a mainstay in the logging industry for years, and many are still in service today. This saw is known for its robust engine, capable of handling demanding tasks like felling large trees and milling lumber. Its popularity stems from its:

• Powerful Engine: Typically a 76.5cc two-stroke engine, delivering ample power for demanding tasks.
• Durable Construction: Built with high-quality materials and designed to withstand heavy use.
• Reliability: Known for its consistent performance and minimal downtime when properly maintained.
• Ease of Maintenance: Relatively simple design makes it easier to service and repair compared to some newer models.

However, due to its age, finding a used Stihl 046 in excellent condition requires careful inspection.

Pro Tip #1: The Piston and Cylinder Inspection: Listen to the Heart

The engine is the heart of any chainsaw, and the piston and cylinder are critical components. A damaged piston or cylinder can significantly reduce power, cause starting problems, and lead to costly repairs. This is where I always start my inspection. I remember once buying a “bargain” saw only to discover the cylinder was scored beyond repair. It ended up being an expensive lesson.

Here’s how to check the piston and cylinder:

1. Visual Inspection:

   • Remove the Muffler: Carefully remove the muffler (usually held on by a few bolts). This will give you a direct view of the piston through the exhaust port.
   • Use a Flashlight: Shine a bright flashlight into the exhaust port.
   • Rotate the Engine: Slowly rotate the engine by pulling the starter cord. Watch the piston as it moves up and down.
   • Look for Scratches and Scoring: Examine the piston and cylinder walls for any scratches, scoring, or excessive carbon buildup. Minor scratches might be acceptable on an older saw, but deep scoring is a red flag.
     • Minor Scoring: A few light scratches are usually acceptable, especially on a saw of this age. These might be caused by normal wear and tear.
     • Deep Scoring: Deep scratches, grooves, or pitting indicate significant wear and potential engine damage. This is a major concern.
   • Check for Aluminum Transfer: Look for signs of aluminum transfer on the cylinder walls. This occurs when the piston overheats and melts slightly, leaving aluminum deposits on the cylinder.

   • Compression Test:

   • Purchase a Compression Tester: You can find these at most auto parts stores.

   • Remove the Spark Plug: Carefully remove the spark plug.
   • Attach the Tester: Screw the compression tester into the spark plug hole.
   • Pull the Starter Cord: Pull the starter cord several times until the needle on the tester stops rising.
   • Record the Reading: Note the compression reading. A healthy Stihl 046 should have a compression reading of at least 150 PSI (pounds per square inch). Anything significantly lower indicates wear or damage.

Data Point: A compression reading below 130 PSI suggests significant engine wear and potential problems.

Troubleshooting:

• Low Compression: If the compression is low, the engine may need a new piston, rings, or cylinder. This can be a costly repair.
• Scoring: If you see deep scoring, the cylinder may need to be honed or replaced.
• Aluminum Transfer: Aluminum transfer indicates overheating and potential engine damage.

Actionable Tip: Don’t be afraid to ask the seller if you can perform a compression test. A reputable seller will be willing to let you do this. If they refuse, it’s a red flag.

Pro Tip #2: Fuel and Oil System Integrity: The Lifeline of Performance

The fuel and oil systems are crucial for keeping the engine running smoothly and properly lubricated. Leaks, clogged filters, or a malfunctioning oil pump can lead to engine damage and reduced performance. I remember once having an oil pump fail mid-cut – a scary and messy experience that taught me the importance of checking these systems.

Here’s how to check the fuel and oil systems:

1. Fuel Tank Inspection:

   • Check for Leaks: Inspect the fuel tank for any cracks or leaks. Pay close attention to the seams and around the fuel cap.
   • Examine the Fuel Lines: Check the fuel lines for cracks, brittleness, or signs of deterioration. Old fuel lines can crack and leak, leading to fuel starvation and engine problems.
   • Inspect the Fuel Filter: Locate the fuel filter inside the fuel tank (usually attached to the fuel line). Remove the filter and check for clogs or debris. A clogged fuel filter can restrict fuel flow and cause the engine to run poorly.

   • Oil Tank Inspection:

   • Check for Leaks: Inspect the oil tank for any cracks or leaks.

   • Examine the Oil Line: Check the oil line for cracks or brittleness.
   • Test the Oil Pump: Start the chainsaw and run it briefly. Observe the bar and chain to see if oil is being properly delivered. You should see a visible stream of oil lubricating the chain.

   • Carburetor Inspection:

   • Visual Inspection: Examine the carburetor for any signs of damage or leaks.
   • Check the Air Filter: Remove the air filter and inspect it for dirt and debris. A dirty air filter can restrict airflow and cause the engine to run poorly.
   • Listen for Unusual Noises: Start the chainsaw and listen for any unusual noises coming from the carburetor. These noises could indicate a problem with the carburetor.

Data Point: A chainsaw should use approximately one tank of bar oil for every two tanks of fuel. If you’re using significantly more fuel than oil, there may be a problem with the oil pump.

Troubleshooting:

• Fuel Leaks: Replace any cracked or leaking fuel lines or fuel tanks.
• Clogged Fuel Filter: Replace the fuel filter.
• Oil Pump Failure: If the oil pump is not working, it may need to be repaired or replaced.
• Dirty Air Filter: Clean or replace the air filter.

Actionable Tip: Ask the seller when the fuel filter and air filter were last replaced. Regular maintenance is a sign that the saw has been well cared for.

Pro Tip #3: Bar and Chain Assessment: Cutting Through the Hype

The bar and chain are the business end of the chainsaw, responsible for cutting wood. A worn or damaged bar and chain can significantly reduce cutting efficiency and increase the risk of kickback. I’ve seen people try to squeeze every last bit of life out of a chain, but it’s a false economy. A sharp, well-maintained chain is safer and more efficient.

Here’s how to assess the bar and chain:

1. Bar Inspection:

   • Check for Wear: Examine the bar for wear along the rails (the edges that guide the chain). Excessive wear can cause the chain to wobble and make cutting difficult.
   • Look for Damage: Check for any bends, cracks, or damage to the bar.
   • Inspect the Sprocket Tip: If the bar has a sprocket tip (a small wheel at the end of the bar), make sure it spins freely and is not damaged.
   • Measure the Bar Length: Ensure the bar length is appropriate for the chainsaw and the type of work you’ll be doing.

   • Chain Inspection:

   • Check for Sharpness: Examine the cutting teeth of the chain. They should be sharp and well-defined. A dull chain will require more effort to cut and increase the risk of kickback.
   • Look for Damage: Check for any broken or damaged teeth.
   • Measure the Chain Length: Ensure the chain is the correct length for the bar.
   • Check the Drive Links: Examine the drive links (the parts of the chain that fit into the bar’s groove) for wear or damage.

   • Sprocket Inspection:

   • Check for Wear: Examine the sprocket (the toothed wheel that drives the chain) for wear or damage. A worn sprocket can damage the chain and reduce cutting efficiency.

Data Point: A chain should be sharpened after every few hours of use, depending on the type of wood being cut.

Troubleshooting:

• Worn Bar: Replace the bar if it is excessively worn or damaged.
• Dull Chain: Sharpen the chain or replace it if it is too worn to sharpen.
• Damaged Chain: Replace the chain if it has broken or damaged teeth.
• Worn Sprocket: Replace the sprocket if it is worn or damaged.

Actionable Tip: Ask the seller when the bar and chain were last replaced. A new or recently sharpened chain is a good sign.

Pro Tip #4: Starting and Running Performance: The Proof is in the Pudding

The true test of a chainsaw is how it starts and runs. A chainsaw that is difficult to start, idles poorly, or stalls frequently may have underlying problems. This is where your ears and your nose come in handy. I’ve learned to diagnose a lot just by listening to an engine.

Here’s how to assess the starting and running performance:

1. Starting:

   • Cold Start: Observe how easily the chainsaw starts when it is cold. It should start within a few pulls of the starter cord.
   • Warm Start: Observe how easily the chainsaw starts when it is warm. It should start even more easily than when it is cold.

   • Idling:

   • Smooth Idle: The chainsaw should idle smoothly without stalling or sputtering.
   • Adjustable Idle: The idle speed should be adjustable using the idle adjustment screw.

   • Running:

   • Smooth Acceleration: The chainsaw should accelerate smoothly when you squeeze the throttle.

   • Consistent Power: The chainsaw should maintain consistent power when cutting wood.
   • No Stalling: The chainsaw should not stall or sputter when cutting wood.
   • Listen for Unusual Noises: Listen for any unusual noises coming from the engine while it is running. These noises could indicate a problem.
   • Check the Exhaust: Observe the exhaust smoke. Excessive smoke can indicate a problem with the engine or the fuel mixture.

Data Point: A properly tuned Stihl 046 should have a crisp, responsive throttle and maintain consistent power throughout the RPM range.

Troubleshooting:

• Difficult Starting: Check the spark plug, fuel filter, and carburetor.
• Poor Idling: Adjust the idle speed or clean the carburetor.
• Stalling: Check the fuel filter, air filter, and carburetor.
• Unusual Noises: Investigate the source of the noise. It could be a sign of a serious problem.
• Excessive Smoke: Adjust the fuel mixture or check the engine for wear.

Actionable Tip: Ask the seller to start the chainsaw for you. Observe how easily it starts and runs. Pay attention to any unusual noises or smells.

Pro Tip #5: Overall Condition and History: Connecting the Dots

The overall condition of the chainsaw and its history can provide valuable clues about its reliability and potential problems. A chainsaw that has been well-maintained and properly stored is more likely to be in good working order. It’s like judging a book by its cover, but with a chainsaw!

Here’s how to assess the overall condition and history:

1. Visual Inspection:

   • Check for Damage: Examine the chainsaw for any signs of damage, such as cracks, dents, or missing parts.
   • Look for Rust: Check for rust, especially on the metal parts of the chainsaw. Rust can indicate that the chainsaw has been stored improperly.
   • Inspect the Handles: Check the handles for wear or damage. Worn or damaged handles can make the chainsaw difficult to control.
   • Examine the Safety Features: Make sure all the safety features, such as the chain brake and throttle lock, are working properly.

   • Ask Questions:

   • Maintenance History: Ask the seller about the chainsaw’s maintenance history. How often has it been serviced? What kind of maintenance has been performed?
   • Usage History: Ask the seller about the chainsaw’s usage history. How often has it been used? What kind of work has it been used for?
   • Storage History: Ask the seller how the chainsaw has been stored. Has it been stored indoors or outdoors? Has it been protected from the elements?
   • Reason for Selling: Ask the seller why they are selling the chainsaw.

Data Point: A chainsaw that has been used professionally (e.g., by a logger or arborist) may have seen more use and abuse than a chainsaw that has been used for occasional home use.

Troubleshooting:

• Damage: Assess the severity of the damage. Minor damage may be acceptable, but major damage could indicate a serious problem.
• Rust: Clean off any rust and inspect the underlying metal for damage.
• Missing Parts: Determine if the missing parts are essential for the chainsaw’s operation.
• Incomplete History: Be wary of sellers who are unable or unwilling to provide information about the chainsaw’s history.

Actionable Tip: Trust your gut. If something doesn’t feel right, walk away. There are plenty of other used Stihl 046 chainsaws out there.
