Stihl 009 Specs: 5 Expert Tips for Woodworkers

The Stihl 009 is a compact and versatile chainsaw that has earned a solid reputation among woodworkers and homeowners alike. While newer models boast more power and advanced features, the 009 remains a reliable and affordable option for many tasks. Let’s dive into its specifications and then explore five expert tips to maximize its performance.

Understanding the Stihl 009 Specifications

Before we get into the tips, let’s establish a clear understanding of the Stihl 009’s key specifications. This will help you assess its suitability for your specific needs and understand its limitations.

• Engine Displacement: Typically around 30.1 cc (cubic centimeters). This indicates the engine’s size and power output. A larger displacement generally translates to more power.
• Engine Power: Approximately 1.2 kW (kilowatts), which is roughly 1.6 horsepower. This is a good indicator of the saw’s cutting capability.
• Weight: Around 4.0 kg (8.8 lbs) without the bar and chain. This lightweight design makes it easy to handle and maneuver, especially for extended periods.
• Bar Length: Commonly available with 12-inch (30 cm) or 14-inch (35 cm) bars. The bar length determines the maximum diameter of wood you can cut.
• Fuel Tank Capacity: Approximately 0.27 liters. This dictates how long you can operate the saw before needing to refuel.
• Oil Tank Capacity: Around 0.17 liters. Chain oil lubrication is crucial for smooth cutting and extending the life of the bar and chain.
• Chain Pitch: Typically 3/8″ Picco Micro (PM). This refers to the spacing between the chain’s drive links.
• Chain Gauge: Usually 0.050″ (1.3 mm). This is the thickness of the drive links that fit into the bar groove.

Why are these specs important?

Understanding these specifications allows you to:

• Choose the right saw for the job: A larger tree requires a more powerful saw with a longer bar.
• Maintain the saw properly: Knowing the fuel and oil capacities ensures you’re using the correct mixtures and lubricants.
• Select the correct replacement parts: When replacing the chain or bar, you need to know the pitch and gauge to ensure compatibility.
• Troubleshoot performance issues: Knowing the engine displacement can help diagnose problems related to power loss.

Tip #1: Mastering Chain Sharpening for Optimal Performance

A sharp chain is paramount for efficient and safe chainsaw operation. A dull chain requires more force to cut, increasing the risk of kickback and putting unnecessary strain on the engine. I’ve seen firsthand how a properly sharpened chain can dramatically improve cutting speed and reduce fatigue.

The Importance of a Sharp Chain:

• Safety: A sharp chain bites into the wood cleanly, reducing the likelihood of kickback.
• Efficiency: A sharp chain cuts faster and requires less force, saving you time and energy.
• Saw Longevity: A sharp chain reduces strain on the engine, extending its lifespan.
• Quality of Cut: A sharp chain produces cleaner, more precise cuts.

Sharpening Techniques:

There are two primary methods for sharpening chainsaw chains:

• Hand Sharpening: Using a round file and a file guide. This is a portable and cost-effective method, but requires practice and precision.
• Using a Chainsaw Sharpener: These can be manual or electric. They offer more consistent sharpening angles and depths, making them ideal for beginners.

Hand Sharpening Steps:

1. Secure the Saw: Place the chainsaw in a vise or clamp it securely to a workbench.
2. Identify the Cutter Type: Determine the type of cutter on your chain (e.g., chisel, semi-chisel). This will influence the sharpening angle.
3. Choose the Correct File Size: Consult your chainsaw’s manual to determine the correct round file size for your chain pitch. For a 3/8″ Picco Micro chain, a 5/32″ (4.0 mm) file is typically used.
4. Set the File Guide: Place the file guide on the chain, aligning the file with the cutter’s cutting edge. The guide will ensure you maintain the correct sharpening angle (usually around 30 degrees).
5. Sharpen the Cutter: Using smooth, even strokes, push the file across the cutter’s cutting edge. Maintain consistent pressure and angle. Sharpen each cutter evenly, removing the same amount of material from each. I usually aim for 3-5 strokes per cutter.
6. Lower the Depth Gauges: After sharpening the cutters, use a flat file and a depth gauge tool to lower the depth gauges (rakers). The depth gauges control how much the cutter bites into the wood. If they are too high, the chain will not cut effectively. Consult your chainsaw’s manual for the correct depth gauge setting.
7. Repeat for All Cutters: Repeat steps 4-6 for all cutters on the chain, alternating between left-hand and right-hand cutters.

Using a Chainsaw Sharpener:

1. Secure the Chain: Follow the sharpener’s instructions to secure the chain in the device.
2. Set the Sharpening Angle: Adjust the sharpener to the correct sharpening angle for your chain type.
3. Sharpen Each Cutter: Follow the sharpener’s instructions to sharpen each cutter, ensuring consistent angles and depths.
4. Lower the Depth Gauges: As with hand sharpening, use a flat file and a depth gauge tool to lower the depth gauges.

Pro Tip:

• Keep your files clean: Use a file card to remove metal filings from the file. This will improve its cutting efficiency.
• Avoid over-sharpening: Sharpen only enough to restore the cutting edge. Over-sharpening will shorten the life of the chain.
• Inspect the chain regularly: Look for signs of damage, such as cracks or broken cutters. Replace the chain if necessary.

My Experience:

I remember one instance where I was struggling to fell a small oak tree with my Stihl 009. The saw was bogging down, and the cuts were ragged. After checking the chain, I realized it was severely dull. I took the time to properly sharpen the chain using a file and guide, and the difference was remarkable. The saw cut through the oak like butter, and the felling process became much safer and more efficient. This experience reinforced the importance of maintaining a sharp chain.

Tip #2: Optimizing Fuel and Oil Mixtures for Engine Longevity

The Stihl 009, like most two-stroke engines, requires a precise mixture of fuel and oil for proper lubrication and cooling. Using the wrong mixture can lead to engine damage, reduced performance, and a shortened lifespan. I’ve seen too many engines ruined by improper fuel mixtures, so this is a crucial aspect of chainsaw maintenance.

Understanding the Importance of Fuel and Oil Mixtures:

• Lubrication: Two-stroke engines rely on the oil in the fuel mixture to lubricate the piston, cylinder, and crankshaft. Without adequate lubrication, these components will wear down rapidly.
• Cooling: The oil in the fuel mixture also helps to cool the engine.
• Performance: The correct fuel mixture ensures optimal combustion and power output.

Recommended Fuel and Oil Mixture Ratio:

The recommended fuel and oil mixture ratio for the Stihl 009 is typically 50:1. This means 50 parts gasoline to 1 part two-stroke oil. Always consult your owner’s manual for the specific recommendation for your model.

Choosing the Right Fuel and Oil:

• Fuel: Use unleaded gasoline with a minimum octane rating of 89. Avoid using gasoline that contains ethanol, as it can damage the engine’s fuel system. If you must use ethanol-blended fuel, use it within 30 days and ensure it has a maximum ethanol content of 10%.
• Oil: Use a high-quality two-stroke oil specifically designed for air-cooled engines. Stihl recommends using their own brand of two-stroke oil, but other reputable brands are also acceptable. Look for oil that meets or exceeds the API TC or JASO FD standards.

Mixing Fuel and Oil:

1. Use a Clean Container: Use a clean, approved fuel container to mix the fuel and oil.
2. Add the Oil First: Pour the correct amount of two-stroke oil into the container. For a 50:1 mixture, you would add 2.6 fluid ounces (77 ml) of oil to 1 gallon (3.8 liters) of gasoline.
3. Add the Gasoline: Pour the gasoline into the container, being careful not to spill.
4. Mix Thoroughly: Shake the container vigorously for at least 30 seconds to ensure the fuel and oil are properly mixed.

Pro Tips:

• Mix Fresh Fuel: Always mix fresh fuel before each use. Fuel that has been sitting for more than 30 days can degrade and lose its octane rating.
• Store Fuel Properly: Store fuel in a cool, dry place away from direct sunlight. Use a fuel stabilizer to extend the shelf life of the fuel.
• Empty the Fuel Tank: If you are not going to use the chainsaw for an extended period, empty the fuel tank and run the engine until it stalls. This will prevent the fuel from gumming up the carburetor.
• Use Pre-Mixed Fuel: For convenience, you can purchase pre-mixed fuel from Stihl or other retailers. These fuels are formulated to provide optimal performance and protection for your chainsaw.

My Experience:

I once inherited a Stihl 009 from a friend who had neglected its maintenance. The saw ran poorly and lacked power. After inspecting the engine, I discovered that the piston and cylinder were scored due to insufficient lubrication. My friend had been using a cheap, low-quality two-stroke oil and had not been mixing the fuel properly. This experience taught me the importance of using high-quality fuel and oil and mixing them correctly.

Tip #3: Implementing Safe Felling Techniques for Small Trees

The Stihl 009, with its lightweight design and manageable power, is well-suited for felling small trees. However, felling any tree requires careful planning and execution to ensure safety. I’ve witnessed numerous accidents caused by improper felling techniques, so it’s crucial to prioritize safety above all else.

Before You Begin:

• Assess the Tree: Before felling any tree, carefully assess its size, lean, and any potential hazards, such as dead branches or power lines.
• Plan Your Escape Route: Identify a clear escape route that is at a 45-degree angle away from the direction of the fall.
• Clear the Area: Remove any obstacles from the area around the tree, including brush, rocks, and debris.
• Wear Proper Safety Gear: Always wear a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.

Felling Techniques for Small Trees:

1. The Undercut: The undercut is a notch cut into the tree on the side you want it to fall. It helps to control the direction of the fall and prevent the tree from splitting or barber-chairing (splitting vertically up the trunk).

   • Cut a Horizontal Notch: Make a horizontal cut into the tree trunk, about one-third of the way through.
   • Cut a Sloping Notch: Make a sloping cut that meets the horizontal cut, creating a wedge-shaped notch. The angle of the sloping cut should be about 45 degrees.

   • The Back Cut: The back cut is made on the opposite side of the tree from the undercut. It severs the remaining wood fibers and allows the tree to fall.

   • Position the Back Cut: Start the back cut slightly above the horizontal cut of the undercut.
   • Leave a Hinge: Leave a hinge of uncut wood between the back cut and the undercut. The hinge helps to control the direction of the fall and prevent the tree from kicking back. The width of the hinge should be about 10% of the tree’s diameter.
   • Complete the Back Cut: Slowly and carefully complete the back cut, being mindful of the tree’s lean and any potential hazards.

   • Wedges (Optional): If the tree is leaning in the wrong direction or if you are concerned about it falling unpredictably, you can use felling wedges to help guide the fall.

   • Insert Wedges: Insert felling wedges into the back cut, behind the chainsaw bar.

   • Drive the Wedges: Use a hammer or axe to drive the wedges into the back cut, gradually lifting the tree in the desired direction.

Pro Tips:

• Use a Felling Lever: A felling lever can be used to help push the tree over in the desired direction.
• Watch for Kickback: Kickback occurs when the tip of the chainsaw bar contacts an object, causing the saw to suddenly jump back towards the operator. Be aware of the risk of kickback and take precautions to avoid it.
• Call for Help: If you are unsure about any aspect of the felling process, call for help from a qualified arborist or experienced logger.

My Experience:

I once attempted to fell a small pine tree without properly assessing its lean. The tree was leaning slightly towards a nearby fence, but I didn’t account for it. As I made the back cut, the tree started to fall in the direction of the fence. I quickly realized my mistake and was able to push the tree in the opposite direction just before it hit the fence. This experience taught me the importance of carefully assessing the tree’s lean and planning the felling process accordingly.

Tip #4: Efficient Bucking and Limb Removal Techniques

Once a tree is felled, the next step is to buck it into manageable lengths and remove the limbs. The Stihl 009 is well-suited for these tasks, but it’s important to use efficient and safe techniques.

Bucking Techniques:

Bucking is the process of cutting a felled tree into shorter lengths. The length of the bucked logs will depend on your intended use (e.g., firewood, lumber).

• Plan Your Cuts: Before you start bucking, plan your cuts to minimize waste and maximize the yield of usable wood.
• Support the Log: Ensure the log is properly supported to prevent it from pinching the chainsaw bar during the cut. Use logs, rocks, or other supports to lift the log off the ground.
• Cutting Techniques:
  • Overbucking: Cutting from the top down. This is best for logs that are supported on both ends.
  • Underbucking: Cutting from the bottom up. This is best for logs that are supported in the middle.
  • Combination Cutting: A combination of overbucking and underbucking. This is useful for logs that are partially supported.
• Avoid Pinching: If the chainsaw bar starts to get pinched during the cut, stop cutting and use a wedge to open the cut.

Limb Removal Techniques:

Limb removal is the process of removing the branches from a felled tree.

• Work from the Base to the Tip: Start removing the limbs from the base of the tree and work your way towards the tip.
• Cut on the Underside of the Limb: Cut the limbs from the underside, close to the trunk. This will prevent the bark from tearing and make the cut cleaner.
• Avoid Cutting into the Trunk: Be careful not to cut into the trunk when removing the limbs.
• Use Proper Body Positioning: Maintain a stable stance and keep your body out of the line of the chainsaw.

Pro Tips:

• Use a Log Peavey: A log peavey is a tool used to roll and position logs. It can be helpful for bucking and limb removal.
• Use a Chainsaw Hook: A chainsaw hook can be used to pull branches out of the way.
• Be Aware of Spring Poles: Spring poles are small trees or branches that are bent under tension. Be careful when cutting spring poles, as they can snap back and cause injury.

My Experience:

I once spent an entire day bucking a large oak tree into firewood without properly supporting the log. The chainsaw bar kept getting pinched, and I had to constantly stop cutting and use a wedge to open the cut. It was a frustrating and time-consuming experience. The next time I bucked a log, I made sure to properly support it, and the process was much faster and easier. This taught me the importance of proper log support.
