Today, I’m going to share my expertise on using the Stihl MS310, a reliable workhorse, for the specific task of cutting oak firewood. We’ll delve deep into its specs, maintenance, and, most importantly, five expert tips to maximize your efficiency and safety when wrestling with this king of hardwoods.

Stihl MS310 Specs (5 Expert Tips for Oak Firewood Cutting)

Oak firewood is prized for its high BTU (British Thermal Unit) output, long burn time, and pleasant aroma. However, its density and hardness present unique challenges. The Stihl MS310, while not the largest saw in Stihl’s lineup, is a popular choice for homeowners and small-scale firewood producers due to its balance of power, weight, and affordability. But mastering its use with oak requires understanding both the saw and the wood.

Understanding the Stihl MS310: A Workhorse for Firewood

Before we dive into cutting techniques, let’s get acquainted with the Stihl MS310. Knowing its specifications and limitations is crucial for safe and efficient operation.

• Engine: 59 cc (3.6 cu. in.) two-stroke engine
• Power Output: 3.1 kW (4.2 bhp)
• Weight (powerhead only): 5.9 kg (13 lbs)
• Guide Bar Lengths: Typically available with 16″, 18″, or 20″ bars. For oak, I generally recommend an 18″ bar as a good compromise between maneuverability and cutting capacity. A 20″ bar is useful for larger diameter logs, but requires more power and skill.
• Fuel Tank Capacity: 0.56 liters (18.9 oz)
• Oil Tank Capacity: 0.33 liters (11.2 oz)
• Chain Oil: Stihl recommends their own brand, but any high-quality bar and chain oil designed for chainsaws will suffice. I personally use a synthetic blend for its superior lubrication and reduced wear.
• Chain Type: Typically uses a 3/8″ pitch chain with a .050″ gauge. The specific type of chain (e.g., chisel, semi-chisel) will affect cutting speed and sharpness. For oak, I prefer a chisel chain for its aggressive cutting action, but it requires more frequent sharpening.
• Anti-Vibration System: Stihl’s anti-vibration system helps reduce fatigue during extended use.
• Chain Brake: A safety feature that stops the chain immediately in case of kickback. Always ensure it’s functioning properly.

Key Takeaway: The MS310 is a mid-range saw, capable of handling most oak firewood cutting tasks. However, it’s not a substitute for proper technique and maintenance. Overloading the saw by forcing it through thick oak will lead to overheating, premature wear, and potential damage.

The Nature of Oak: Green vs. Seasoned

Understanding the wood you’re cutting is just as important as understanding the saw. Oak undergoes significant changes as it dries, affecting how it cuts and splits.

• Green Oak: Freshly cut oak is often referred to as “green” wood. It has a high moisture content (often above 50%) and is significantly heavier than seasoned oak. Green oak is easier to split immediately after felling, but more difficult to cut with a chainsaw due to its higher moisture content which can bind the chain. The sap can also gum up the saw.
• Seasoned Oak: Oak that has been allowed to air-dry for at least 6-12 months is considered seasoned. The moisture content drops to around 20%, making it lighter and easier to burn. Seasoned oak is harder to split, but generally cuts cleaner with a chainsaw.
• Moisture Content and BTU: The higher the moisture content, the lower the BTU output of the firewood. Burning green oak wastes energy as the fire must first evaporate the water before it can generate heat. It also produces more smoke and creosote, increasing the risk of chimney fires.

My Experience: I once made the mistake of trying to burn exclusively green oak. The fire was difficult to start, produced minimal heat, and coated my chimney with a thick layer of creosote. It was a valuable lesson in the importance of proper seasoning.

Key Takeaway: Ideally, you want to cut and split oak when it’s green and then allow it to season for at least a year before burning. This balances ease of splitting with optimal burning characteristics.

5 Expert Tips for Cutting Oak Firewood with a Stihl MS310

Now, let’s get to the heart of the matter: how to effectively and safely cut oak firewood using the Stihl MS310. These tips are based on years of experience and are designed to maximize your efficiency and minimize the risk of accidents.

Tip #1: Sharpen Your Chain – The Cornerstone of Safe and Efficient Cutting

A sharp chain is the single most important factor in safe and efficient chainsaw operation, especially when cutting dense hardwoods like oak. A dull chain requires more force to cut, increasing the risk of kickback and putting unnecessary strain on the saw’s engine.

• Signs of a Dull Chain:
  • The saw produces fine sawdust instead of chips.
  • You have to apply excessive pressure to make the saw cut.
  • The saw pulls to one side or vibrates excessively.
  • The cut is uneven or ragged.
• Sharpening Tools:
  • Round File and Guide: This is the most common and affordable method. Use a file of the correct diameter for your chain (typically 5/32″ for a 3/8″ pitch chain). The guide helps maintain the correct filing angle and depth.
  • Electric Chain Sharpener: These sharpeners are faster and more precise than hand filing, but require more investment.
  • Professional Sharpening: If you’re not comfortable sharpening your own chain, you can take it to a professional.
• Sharpening Technique:
  1. Secure the chainsaw in a vise or clamp.
  2. Use the file guide to maintain the correct angle (typically 30 degrees for the top plate and 10 degrees for the side plate). Refer to your chain manufacturer’s specifications for the exact angles.
  3. File each tooth evenly, using smooth, consistent strokes.
  4. Check the depth gauges (rakers) and file them down if necessary. The depth gauges control how much the chain bites into the wood. If they are too high, the chain will not cut effectively.
• Frequency: Sharpen your chain every time you refuel or whenever you notice a decrease in cutting performance. With oak, this might be more frequent than with softer woods.
• Chain Maintenance: Regularly inspect your chain for damage, such as cracked or broken teeth. Replace the chain when it becomes excessively worn or damaged.

My Experience: I used to think I could get away with infrequent sharpening. However, I quickly learned that a dull chain not only made the job harder but also increased the risk of kickback. Now, I sharpen my chain religiously, and it makes a world of difference. I carry a small file and guide with me in the field to touch up the chain as needed.

Case Study: A local firewood producer I know used to struggle with consistently cutting through oak. He was constantly overheating his saws and experiencing excessive chain wear. After I showed him the importance of proper chain sharpening and maintenance, his production increased by 25%, and his saw maintenance costs decreased significantly.

Key Takeaway: A sharp chain is not just about speed; it’s about safety, efficiency, and prolonging the life of your chainsaw. Invest in the right sharpening tools and learn how to use them properly.

Tip #2: Wedges are Your Friends – Preventing Pinching and Kickback

Pinching occurs when the weight of the log closes in on the chainsaw bar during a cut, trapping the chain and potentially causing kickback. Wedges are essential tools for preventing pinching, especially when cutting larger diameter oak logs.

• Types of Wedges:
  • Plastic Wedges: These are lightweight and won’t damage your chain if you accidentally hit them with the saw. They are ideal for general use.
  • Aluminum Wedges: More durable than plastic wedges, but can still damage your chain if hit.
  • Steel Wedges: The most durable type, but also the most likely to damage your chain. Use them with caution.
• Wedge Placement:
  1. Make your initial cut, inserting the wedge into the kerf (the cut you’ve made) behind the bar.
  2. Use a hammer or mallet to drive the wedge further into the kerf, opening the cut and preventing the log from closing in on the bar.
  3. Continue cutting, adding more wedges as needed.
• Felling Wedges: These are larger and more aggressive wedges designed to help direct the fall of a tree. While not always necessary for firewood cutting, they can be useful for controlling the direction of larger logs.
• Avoiding Kickback: Never cut with the tip of the bar, as this is the area most prone to kickback. Always maintain a firm grip on the saw with both hands.

My Experience: I’ve had my fair share of close calls with pinching and kickback. One time, I was cutting a large oak log without using wedges, and the log suddenly shifted, pinching the bar and throwing the saw back towards me. Fortunately, the chain brake engaged, preventing serious injury. That experience taught me the importance of always using wedges, especially when cutting large or unstable logs.

Data Point: According to the U.S. Consumer Product Safety Commission, kickback is the leading cause of chainsaw injuries. Using wedges can significantly reduce the risk of this type of accident.

Key Takeaway: Wedges are a simple but effective tool for preventing pinching and kickback. Always use them when cutting larger diameter logs or when there is a risk of the log shifting.

Tip #3: Leverage Gravity – Efficient Bucking Techniques

Bucking is the process of cutting a felled tree into smaller, more manageable lengths. Efficient bucking techniques can save you time and energy, especially when dealing with heavy oak logs.

• Cutting on the Ground: This is the simplest method, but it can be tiring and increase the risk of pinching.
  • Single Cut: Support the log on one side and cut through from the top. This is suitable for smaller logs.
  • Double Cut: Make a partial cut from the top, then roll the log over and complete the cut from the bottom. This is useful for larger logs, but requires more effort to roll the log.
• Cutting on a Sawbuck: A sawbuck is a simple wooden frame that supports the log off the ground, making it easier to cut.
  • Even Weight Distribution: Ensure the log is evenly supported on the sawbuck to prevent it from rolling or shifting during cutting.
  • Multiple Logs: You can cut multiple smaller logs at once on a sawbuck, increasing your efficiency.
• Cutting on a Log Lifter: A log lifter is a mechanical device that raises the log off the ground, making it easier to cut and reducing strain on your back.
  • Hydraulic Log Lifter: These are the most powerful and efficient type of log lifter, but they are also the most expensive.
  • Manual Log Lifter: These are less expensive than hydraulic log lifters, but require more manual effort.
• Bore Cutting: A technique where you plunge the tip of the saw into the log to create a cut from the inside out. This can be useful for relieving tension and preventing pinching, but it requires a high level of skill and caution. I strongly advise against bore cutting unless you are an experienced chainsaw operator.
• “Noodle” Cutting: This technique involves making overlapping cuts to remove a section of wood, creating a “noodle” shape. It’s useful for removing knots or other obstructions.

My Experience: I used to struggle with back pain after a long day of bucking firewood. I tried various techniques, but nothing seemed to help until I started using a log lifter. The log lifter significantly reduced the strain on my back, and I was able to work much more efficiently.

Case Study: A small-scale firewood business I consulted with was struggling to meet demand. They were using inefficient bucking techniques, which resulted in low production and high labor costs. After implementing a combination of sawbucks and log lifters, their production increased by 40%, and their labor costs decreased significantly.

Key Takeaway: Choose the bucking technique that is most appropriate for the size and weight of the logs you are cutting. Consider using a sawbuck or log lifter to reduce strain on your back and increase your efficiency.

Tip #4: Chain Tension and Lubrication – Preventing Premature Wear

Proper chain tension and lubrication are essential for prolonging the life of your chain and bar, especially when cutting dense hardwoods like oak.

• Chain Tension:
  • Too Loose: A loose chain can derail from the bar, causing damage to the chain and potentially injuring the operator.
  • Too Tight: A tight chain can overheat and wear out prematurely.
  • Proper Tension: The chain should be snug against the bar, but you should still be able to pull it around the bar by hand.
• Checking Chain Tension:
  1. Turn off the saw and allow it to cool down.
  2. Loosen the bar nuts.
  3. Use a screwdriver or wrench to adjust the tensioning screw until the chain is properly tensioned.
  4. Tighten the bar nuts securely.
• Chain Lubrication:
  • Bar and Chain Oil: Use a high-quality bar and chain oil designed for chainsaws.
  • Automatic Oiler: Most chainsaws have an automatic oiler that lubricates the chain as it cuts. Check the oil level regularly and refill as needed.
  • Manual Oiling: Some chainsaws also have a manual oiler that allows you to apply extra oil to the chain when needed.
• Signs of Insufficient Lubrication:
  • The chain smokes or overheats.
  • The bar turns blue.
  • The chain wears out prematurely.

My Experience: I once neglected to check the oil level on my chainsaw and ended up running it dry. The chain quickly overheated and wore out, and the bar was damaged beyond repair. It was a costly mistake that taught me the importance of regular maintenance.

Data Point: Studies have shown that proper chain lubrication can extend the life of a chainsaw chain by up to 50%.

Key Takeaway: Check your chain tension and oil level regularly, especially when cutting oak. Use a high-quality bar and chain oil and adjust the chain tension as needed.

Tip #5: Personal Protective Equipment (PPE) – Your First Line of Defense

Chainsaw operation is inherently dangerous, and personal protective equipment (PPE) is essential for minimizing the risk of injury.

• Required PPE:
  • Chainsaw Chaps: These are designed to stop the chain in case of contact with your legs.
  • Safety Glasses or Face Shield: Protect your eyes from flying debris.
  • Hearing Protection: Chainsaws are loud, and prolonged exposure to high noise levels can damage your hearing.
  • Gloves: Protect your hands from cuts and abrasions.
  • Steel-Toed Boots: Protect your feet from falling logs and chainsaw cuts.
  • Helmet: Protect your head from falling branches and other hazards.
• Additional PPE:
  • First Aid Kit: Keep a well-stocked first aid kit readily available.
  • Whistle: Use a whistle to signal for help in case of an emergency.
  • Communication Device: Carry a cell phone or two-way radio to communicate with others.

My Experience: I’ve witnessed several chainsaw accidents over the years, and in almost every case, the injuries were exacerbated by the lack of proper PPE. I always wear the full complement of PPE when operating a chainsaw, and I encourage everyone else to do the same.

Case Study: A local logging company I worked with implemented a mandatory PPE policy for all employees. As a result, their accident rate decreased by 75%.

Key Takeaway: Always wear the full complement of PPE when operating a chainsaw. It’s a small investment that can save you from serious injury. Don’t compromise on safety!
