5 Expert Tips for Firewood Preparation with the Stihl MS 362 C
Now that we’ve covered the technical specifications, let’s dive into some practical tips for using the Stihl MS 362 C to prepare firewood efficiently and safely.
1. Wood Selection: Knowing Your Fuel
Not all wood is created equal. The type of wood you choose significantly impacts its heating value, burn time, and the amount of creosote it produces. This isn’t just anecdotal; there’s real science behind it.
- Hardwoods vs. Softwoods: Hardwoods, like oak, maple, beech, and ash, are denser and contain more energy per unit volume than softwoods, such as pine, fir, and spruce. This means they burn longer and produce more heat.
-
Heating Value (BTU): The heating value of wood is measured in British Thermal Units (BTU) per cord. A cord is a stack of wood measuring 4 feet high, 4 feet wide, and 8 feet long, totaling 128 cubic feet. Here’s a comparison of the approximate BTU content per cord for common firewood species:
- Oak (Red/White): 24-28 million BTU
- Maple (Sugar/Red): 20-24 million BTU
- Beech: 22-26 million BTU
- Ash: 20-24 million BTU
- Birch (Yellow/White): 20-24 million BTU
- Pine (White/Yellow): 12-16 million BTU
- Fir (Douglas/Balsam): 14-18 million BTU
- Spruce: 12-16 million BTU
Insight: While softwoods burn faster, they can be useful for starting fires. I often keep a supply of pine kindling on hand for this purpose.
-
Seasoning: Freshly cut wood, known as green wood, contains a high moisture content, typically ranging from 30% to over 60%. Burning green wood is inefficient because much of the energy is used to evaporate the water, resulting in less heat output and increased creosote buildup in your chimney. Seasoning involves drying the wood to reduce its moisture content to 20% or less.
- Drying Time: The drying time varies depending on the wood species, climate, and stacking method. Generally, hardwoods require at least 6-12 months of seasoning, while softwoods may season in 3-6 months.
- Moisture Meter: A moisture meter is an invaluable tool for determining the moisture content of firewood. I use a simple pin-type meter and aim for a reading of 20% or less before burning.
- Stacking Method: Proper stacking is crucial for efficient seasoning. Stack the wood in a single row, off the ground, with good air circulation around each piece. I prefer to stack my firewood on pallets to keep it off the ground and allow air to circulate underneath.
- Case Study: I once made the mistake of burning unseasoned oak in my wood stove. The fire was difficult to start, produced little heat, and filled my chimney with creosote. After that experience, I always make sure my firewood is properly seasoned before burning it.
2. Chainsaw Calibration and Maintenance: Keeping Your Saw Sharp
A dull chainsaw is not only inefficient but also dangerous. A sharp chain cuts smoothly and predictably, while a dull chain can grab, kick back, and require excessive force, increasing the risk of injury. Regular calibration and maintenance are essential for keeping your Stihl MS 362 C in top condition.
-
Chain Sharpening: Sharpening your chainsaw chain is a skill that every firewood processor should master. A properly sharpened chain will cut faster, require less effort, and reduce wear and tear on your saw.
- Tools: You’ll need a chainsaw sharpening kit, which typically includes a round file, a flat file, a depth gauge tool, and a guide. I prefer to use a file guide to ensure consistent sharpening angles.
- Technique: Follow the manufacturer’s instructions for your sharpening kit. The key is to maintain the correct filing angle and depth for each cutter. I typically sharpen my chain after every few tanks of fuel, or whenever I notice it’s not cutting as smoothly as it should.
- Professional Sharpening: If you’re not comfortable sharpening your own chain, you can take it to a professional. A good sharpening service can restore a dull chain to like-new condition.
-
Carburetor Adjustment: The carburetor controls the air-fuel mixture in the engine. If your chainsaw is running poorly, it may need a carburetor adjustment. The Stihl MS 362 C with M-Tronic automatically adjusts the carburetor, but in some cases, manual adjustment may be necessary.
-
Procedure: Consult your owner’s manual for specific instructions on carburetor adjustment. Generally, you’ll need to adjust the high (H) and low (L) speed screws to achieve the optimal air-fuel mixture.
- Caution: Carburetor adjustment can be tricky. If you’re not comfortable doing it yourself, take your saw to a qualified technician.
-
Air Filter Cleaning: A clean air filter is essential for proper engine performance. A clogged air filter restricts airflow, causing the engine to run rich and lose power.
-
Frequency: Clean the air filter after every few hours of use, or more frequently in dusty conditions.
- Procedure: Remove the air filter cover and gently brush or blow off any debris. You can also wash the filter with soap and water, but make sure it’s completely dry before reinstalling it.
-
Spark Plug Maintenance: A faulty spark plug can cause starting problems and poor engine performance.
-
Inspection: Inspect the spark plug regularly for signs of wear or damage. Replace it if necessary.
- Gap Setting: Ensure the spark plug gap is set to the correct specification, as indicated in your owner’s manual.
-
Bar and Chain Lubrication: Proper lubrication is essential for extending the life of your guide bar and chain.
-
Oil Level: Check the oil level frequently and refill as needed.
- Oil Type: Use a high-quality chainsaw bar and chain oil. I prefer to use a synthetic oil for better performance and lubrication.
- Oil Flow: Check the oil flow to ensure the chain is being properly lubricated. You should see a light spray of oil coming off the chain while it’s running.
3. Safe Cutting Techniques: Protecting Yourself
Chainsaw operation is inherently dangerous. According to the CDC, chainsaws cause approximately 36,000 injuries each year in the United States alone. Proper safety precautions are essential for preventing accidents and injuries. I’ve personally witnessed several near-misses over the years, and they’ve reinforced the importance of safety in my own work.
-
Personal Protective Equipment (PPE): Always wear appropriate PPE when operating a chainsaw. This includes:
- Eye Protection: Safety glasses or a face shield to protect your eyes from flying debris.
- Hearing Protection: Earplugs or earmuffs to protect your hearing from the loud noise of the chainsaw.
- Head Protection: A hard hat to protect your head from falling branches or other hazards.
- Hand Protection: Heavy-duty work gloves to protect your hands from cuts and abrasions.
- Leg Protection: Chainsaw chaps or pants to protect your legs from chainsaw cuts. These are perhaps the most important piece of PPE, as leg injuries are the most common type of chainsaw accident. I always wear chainsaw chaps, even for small jobs.
- Foot Protection: Steel-toed boots to protect your feet from falling objects and chainsaw cuts.
-
Safe Cutting Practices:
-
Clear the Work Area: Before starting the chainsaw, clear the work area of any obstacles, such as rocks, branches, or debris.
- Stable Footing: Maintain a stable footing and avoid cutting in awkward positions.
- Two-Handed Grip: Always use a two-handed grip on the chainsaw.
- Avoid Kickback: Kickback occurs when the tip of the chainsaw bar contacts an object, causing the saw to suddenly kick back towards the operator. To avoid kickback, avoid using the tip of the bar and be aware of your surroundings.
- Proper Stance: Stand to the side of the cutting path, not directly behind it.
- Never Cut Above Shoulder Height: Cutting above shoulder height is dangerous and increases the risk of losing control of the saw.
- Shut Down the Saw: Always shut down the saw before moving it or performing any maintenance.
- First Aid Kit: Keep a well-stocked first aid kit on hand in case of an accident. Make sure you know how to use the contents of the kit.
- Emergency Plan: Have an emergency plan in place in case of a serious injury. Know how to call for help and provide your location.
4. Bucking and Splitting Techniques: Maximizing Efficiency
Bucking is the process of cutting logs into shorter lengths, typically 16 inches for firewood. Splitting is the process of splitting the rounds into smaller pieces for easier burning. Efficient bucking and splitting techniques can significantly reduce the time and effort required to prepare firewood.
-
Bucking Techniques:
- Log Support: Support the log to prevent it from pinching the chainsaw bar. You can use log stands, sawhorses, or other logs for support.
- Cutting Sequence: Use a combination of overcuts and undercuts to avoid pinching the bar. An overcut is a cut made from the top of the log, while an undercut is a cut made from the bottom.
- Bore Cutting: Bore cutting is a technique used to cut through thick logs. It involves plunging the tip of the chainsaw bar into the log and then pivoting the saw to make the cut. Be extremely cautious when bore cutting, as it can increase the risk of kickback.
- Rolling Logs: Use a cant hook or peavey to safely roll logs into position for bucking. Never attempt to roll a log by hand.
-
Splitting Techniques:
-
Manual Splitting: Manual splitting involves using a splitting axe or maul to split the rounds. This is a physically demanding task, but it can be a good workout.
- Hydraulic Log Splitter: A hydraulic log splitter is a machine that uses hydraulic power to split the rounds. This is a much faster and easier way to split wood than manual splitting. I use a 25-ton hydraulic splitter for most of my splitting.
- Splitting Wedge: A splitting wedge can be used to split particularly tough or knotty rounds. Drive the wedge into the round with a sledgehammer.
- Proper Stance: Maintain a stable stance and keep your feet out of the path of the axe or maul.
- Safety Glasses: Wear safety glasses to protect your eyes from flying chips of wood.
- Log Dimensions: The ideal size of firewood depends on the size of your wood stove or fireplace. Generally, 16-inch lengths are a good choice. The diameter of the rounds should be small enough to fit comfortably in your stove or fireplace.
5. Storage and Seasoning: The Final Touches
Proper storage and seasoning are essential for ensuring your firewood is ready to burn efficiently and cleanly.
- Stacking: Stack the firewood in a single row, off the ground, with good air circulation around each piece.
- Location: Choose a location that is sunny and well-ventilated. Avoid stacking firewood in damp or shaded areas.
- Covering: Cover the top of the firewood stack with a tarp or roof to protect it from rain and snow. Leave the sides open to allow for air circulation.
- Air Circulation: Ensure good air circulation around the firewood stack to promote drying.
- Moisture Content Monitoring: Use a moisture meter to monitor the moisture content of the firewood. Aim for a moisture content of 20% or less before burning.
- Pest Control: Inspect the firewood for signs of pests, such as insects or rodents. Treat the firewood if necessary to prevent infestations.
- Storage Duration: Allow the firewood to season for at least 6-12 months, or longer for hardwoods.
