362 CM Stihl Chainsaw (5 Pro Tips For Firewood Efficiency)

Here is your article:

Isn’t it ironic that the tool designed to fell massive trees can also be the key to a cozy winter evening? The Stihl 362 CM chainsaw, a workhorse in the woods, is more than just a lumberjack’s companion; it’s a firewood maestro’s best friend. I’ve spent countless hours alongside this machine, turning towering logs into manageable, heat-producing fuel. Let me share my insights, not just as a chainsaw operator, but as someone who understands the intimate dance between man, machine, and wood. These aren’t just tips; they’re lessons etched in sawdust and sweat.

Mastering Firewood Efficiency with Your Stihl 362 CM: 5 Pro Tips

The Stihl 362 CM is a powerhouse, but power alone doesn’t guarantee efficiency. It’s about harnessing that power intelligently. These tips will transform you from a casual chainsaw user into a firewood-cutting artisan.

1. Chainsaw Maintenance: The Foundation of Efficiency

A dull chain is an energy vampire, sucking the life out of your chainsaw and your stamina. Proper chainsaw maintenance is the single most important factor in firewood efficiency. I can’t stress this enough.

The Importance of a Sharp Chain

Think of it like this: a sharp chain slices through wood; a dull chain grinds. Grinding creates more friction, requiring more power and ultimately wasting fuel. It also puts unnecessary strain on the chainsaw engine, shortening its lifespan. A sharp chain allows you to cut faster, cleaner, and with less effort. This directly translates into more firewood processed per hour.

Sharpening Techniques

I prefer using a chainsaw file. It gives me more control and allows me to maintain the correct cutting angles. Here’s my process:

Secure the Chainsaw: Use a vise or clamp to keep the chainsaw bar stable.
Choose the Right File: Match the file size to your chain pitch (typically 5/32″ for a 3/8″ pitch chain, which is common on the 362 CM).
Maintain the Correct Angle: Follow the existing angle of the cutter. Most chainsaws have markings on the cutter to guide you.
File Consistently: Use smooth, even strokes, filing from the inside of the cutter outwards. Aim for 3-5 strokes per cutter.
Check Depth Gauges: Use a depth gauge tool to ensure the depth gauges (the little “ramps” in front of each cutter) are at the correct height. If they’re too high, the chain won’t bite into the wood effectively. File them down carefully with a flat file if needed.

I usually sharpen my chain after every two tanks of gas, or sooner if I notice the chain starting to cut slower or produce fine sawdust instead of chips.

Chain Tension Adjustment

Proper chain tension is crucial for both safety and efficiency. A chain that’s too loose can derail and cause serious injury. A chain that’s too tight will bind and overheat.

To adjust the chain tension on your Stihl 362 CM:

Loosen the Bar Nuts: Use the wrench provided with your chainsaw to loosen the bar nuts slightly.
Adjust the Tensioning Screw: Locate the chain tensioning screw (usually on the side of the chainsaw). Turn it clockwise to tighten the chain and counterclockwise to loosen it.
Check the Tension: The chain should be snug against the bar but still be able to be pulled around the bar by hand. You should be able to pull the chain out from the bar about 1/8″ to 1/4″ at the midpoint.
Tighten the Bar Nuts: Once the tension is correct, tighten the bar nuts securely.

I check the chain tension every time I refuel the chainsaw. Temperature changes can affect chain tension, so it’s important to monitor it regularly.

Bar Maintenance

The chainsaw bar also requires regular maintenance. Check it for wear and damage, and clean it regularly.

Clean the Bar Groove: Use a bar groove cleaner to remove sawdust and debris from the bar groove. This ensures proper oil flow to the chain.
Check the Bar Rails: Inspect the bar rails for wear and burrs. If necessary, use a flat file to smooth them out.
Flip the Bar: Periodically flip the bar over to distribute wear evenly.

I clean my bar groove every time I sharpen the chain.

Air Filter Maintenance

A clean air filter is essential for proper engine performance. A clogged air filter restricts airflow, causing the engine to run rich (too much fuel) and lose power.

Clean the Air Filter Regularly: Remove the air filter and clean it with compressed air or warm, soapy water. Allow it to dry completely before reinstalling it.
Replace the Air Filter: Replace the air filter if it’s damaged or excessively dirty.

I clean my air filter after every day of use, or more often if I’m working in dusty conditions.

Fuel and Oil

Using the correct fuel and oil is crucial for engine longevity.

Use High-Quality Fuel: Use fresh, high-octane gasoline (at least 89 octane). Avoid using old or stale fuel.
Use Stihl 2-Cycle Oil: Use Stihl-branded 2-cycle oil mixed at the correct ratio (usually 50:1). This oil is specifically formulated for Stihl engines and provides excellent lubrication and protection.
Use Bar and Chain Oil: Use a high-quality bar and chain oil to lubricate the chain and bar. This oil helps to reduce friction and wear.

I always use Stihl fuel and oil in my 362 CM. It’s a small investment that pays off in the long run.

Takeaway: Regular chainsaw maintenance is the cornerstone of efficient firewood processing. A sharp chain, proper chain tension, a clean bar, a clean air filter, and the right fuel and oil will significantly improve your productivity and extend the life of your chainsaw.

2. Felling Techniques: Strategic Cuts for Easier Processing

How you fell a tree directly impacts how easily you can process it into firewood. Strategic felling can save you time, energy, and frustration. I’ve learned this the hard way, after spending hours wrestling with awkwardly positioned logs.

Planning Your Fell

Before you even start your chainsaw, take a moment to assess the tree and its surroundings.

Identify the Lean: Determine the natural lean of the tree. This is the direction the tree will most likely fall.
Check for Obstacles: Look for obstacles such as other trees, power lines, fences, and buildings.
Plan Your Escape Route: Identify a clear escape route at a 45-degree angle away from the direction of the fall.

I always walk around the tree at least twice before making any cuts. It’s better to be safe than sorry.

The Hinge

The hinge is the key to controlling the direction of the fall. It’s a strip of wood left uncut on the back of the tree.

Make the Face Cut: The face cut consists of two cuts that form a wedge shape. The depth of the face cut should be about 1/3 of the tree’s diameter.
Make the Back Cut: The back cut is made on the opposite side of the tree from the face cut. It should be slightly higher than the bottom of the face cut.
Leave the Hinge: Leave a hinge of uncut wood between the face cut and the back cut. The width of the hinge should be about 1/10 of the tree’s diameter.

The hinge acts as a rudder, guiding the tree as it falls.

Using Wedges

If the tree is leaning in the wrong direction, you can use wedges to help guide its fall.

Insert Wedges: Insert wedges into the back cut before completing it.
Hammer the Wedges: Hammer the wedges in to lift the tree and force it to fall in the desired direction.

I always carry a couple of wedges with me when felling trees. They can be a lifesaver.

Limbing and Bucking

Once the tree is on the ground, it’s time to limb it and buck it into manageable lengths.

Limbing: Remove the branches from the tree. Start from the base of the tree and work your way up. Be careful not to cut yourself with the chainsaw.
Bucking: Cut the tree into desired lengths. I typically buck my firewood into 16-inch lengths, which fit nicely in my wood stove.

When bucking, be mindful of the tree’s tension. If the log is supported at both ends, it will be under compression on top and tension on the bottom. If you cut from the top, the log could pinch your chainsaw. To avoid this, cut halfway through from the top, then finish the cut from the bottom.

Takeaway: Strategic felling techniques, including proper planning, hinge creation, and the use of wedges, can significantly reduce the effort required to process firewood. Understanding tension and compression in logs is crucial for safe and efficient bucking.

3. The Right Equipment: Beyond the Chainsaw

While the Stihl 362 CM is the star of the show, other tools play supporting roles in efficient firewood processing. Investing in the right equipment can save you time, energy, and your back.

Log Splitters: Hydraulic vs. Manual

Log splitters come in two main varieties: hydraulic and manual.

Hydraulic Log Splitters: These are powered by a hydraulic pump and are capable of splitting even the toughest logs. They’re ideal for processing large quantities of firewood. I use a 27-ton hydraulic log splitter. It makes quick work of even the gnarliest oak logs.
Manual Log Splitters: These rely on human power and are best suited for splitting smaller logs or for occasional use. They’re more affordable than hydraulic log splitters but require more physical effort.

When choosing a log splitter, consider the size and type of wood you’ll be splitting. For hardwood like oak or maple, you’ll need a more powerful splitter than for softwood like pine or fir.

Wedges and Sledges

Even with a log splitter, wedges and sledges are still essential tools.

Wedges: Use wedges to split logs that are too large or too knotty for the log splitter.
Sledges: Use a sledgehammer to drive the wedges into the logs.

I keep a variety of wedges and sledges on hand. Different sizes and shapes are useful for different splitting situations.

Peavies and Cant Hooks

Peavies and cant hooks are used to roll and position logs.

Peavies: These have a pivoting hook that grabs onto the log.
Cant Hooks: These have a fixed hook that grabs onto the log.

Both peavies and cant hooks can save you a lot of back strain when working with large logs.

Safety Gear

Safety gear is non-negotiable when working with chainsaws and other wood processing tools.

Chainsaw Chaps: These protect your legs from chainsaw cuts.
Eye Protection: Wear safety glasses or a face shield to protect your eyes from flying debris.
Hearing Protection: Wear earplugs or earmuffs to protect your hearing from the loud noise of the chainsaw.
Gloves: Wear gloves to protect your hands and improve your grip.
Steel-Toed Boots: Wear steel-toed boots to protect your feet from falling logs.

I never operate a chainsaw without wearing all of my safety gear. It’s not worth the risk.

Takeaway: Investing in the right equipment, including a log splitter, wedges, sledges, peavies, and safety gear, can significantly improve your efficiency and safety when processing firewood.

4. Wood Stacking and Drying: The Key to Efficient Burning

The work doesn’t end when the wood is split. Proper stacking and drying are crucial for efficient burning. Dry firewood burns hotter, cleaner, and produces less smoke.

Stacking Techniques

The goal of stacking is to maximize airflow around the wood.

Choose a Sunny, Windy Location: This will help the wood dry faster.
Elevate the Wood: Stack the wood on pallets or other supports to keep it off the ground. This prevents moisture from wicking up into the wood.
Stack Loosely: Leave space between the rows of wood to allow for airflow.
Cover the Top: Cover the top of the woodpile with a tarp or other waterproof material to protect it from rain and snow.

I stack my firewood in long rows, with the splits facing up. This allows rainwater to run off easily.

Drying Time

The amount of time it takes for firewood to dry depends on the type of wood, the climate, and the stacking method.

Softwood: Softwood like pine or fir typically takes 6-12 months to dry.
Hardwood: Hardwood like oak or maple typically takes 12-24 months to dry.

I use a moisture meter to check the moisture content of my firewood. The ideal moisture content for burning is below 20%.

Wood Species and BTU Value

Different wood species have different BTU (British Thermal Unit) values, which is a measure of their heat output.

Oak: Oak is a dense hardwood with a high BTU value. It burns hot and long.
Maple: Maple is another dense hardwood with a high BTU value. It’s a good all-around firewood.
Ash: Ash is a medium-density hardwood with a good BTU value. It splits easily and burns cleanly.
Birch: Birch is a medium-density hardwood with a moderate BTU value. It burns quickly and produces a pleasant aroma.
Pine: Pine is a softwood with a low BTU value. It burns quickly and produces a lot of smoke.

I prefer to burn oak and maple in my wood stove. They provide the most heat for the longest amount of time.

Takeaway: Proper stacking and drying are essential for efficient burning. Aim for a moisture content below 20% and choose wood species with high BTU values for optimal heat output.

5. Chainsaw Safety: A Constant Vigil

No amount of efficiency is worth sacrificing safety. Chainsaw operation is inherently dangerous, and complacency can be deadly. I’ve seen firsthand the devastating consequences of chainsaw accidents. Always be vigilant and prioritize safety.

Personal Protective Equipment (PPE)

As mentioned earlier, PPE is non-negotiable. Always wear chainsaw chaps, eye protection, hearing protection, gloves, and steel-toed boots.

Safe Operating Practices

Read the Manual: Familiarize yourself with the chainsaw’s operating manual.
Inspect the Chainsaw: Before each use, inspect the chainsaw for any damage or loose parts.
Start the Chainsaw on the Ground: Never start the chainsaw in the air or on your leg.
Maintain a Firm Grip: Use both hands to hold the chainsaw firmly.
Keep Your Feet Planted: Maintain a stable stance and keep your feet planted firmly on the ground.
Be Aware of Kickback: Kickback is a sudden, uncontrolled movement of the chainsaw bar that can cause serious injury. Be aware of the potential for kickback and take steps to avoid it.
Don’t Overreach: Avoid overreaching or cutting above your head.
Take Breaks: Chainsaw operation can be tiring. Take frequent breaks to avoid fatigue.
Never Work Alone: Always work with a partner in case of an emergency.

I always have a first-aid kit and a cell phone with me when operating a chainsaw.

Kickback Prevention

Kickback is one of the most common causes of chainsaw injuries.

Use a Reduced-Kickback Chain: These chains have a smaller radius on the cutters, which reduces the likelihood of kickback.
Avoid Cutting with the Tip of the Bar: The tip of the bar is the most likely area to cause kickback.
Maintain a Sharp Chain: A dull chain is more likely to cause kickback.
Hold the Chainsaw Firmly: A loose grip can increase the risk of kickback.

I’ve had a few close calls with kickback over the years. It’s a terrifying experience.

Takeaway: Chainsaw safety is paramount. Always wear PPE, follow safe operating practices, and be aware of the potential for kickback. Never let complacency creep in.

Beyond the Basics: Advanced Techniques and Considerations

Once you’ve mastered the basics, you can explore more advanced techniques and considerations to further enhance your firewood efficiency.

Timber Grading and Selection

Understanding timber grading can help you select the best wood for firewood. Timber is graded based on its quality, size, and species. Higher grades of timber are typically used for lumber, while lower grades are often used for firewood.

Grading Systems: Different regions have different timber grading systems. Familiarize yourself with the grading system used in your area.
Species Selection: As mentioned earlier, different wood species have different BTU values. Choose species that are well-suited for firewood.
Defect Identification: Learn to identify defects in timber, such as knots, rot, and insect damage. These defects can affect the wood’s burning properties.

I often visit local sawmills to purchase low-grade timber for firewood. It’s a cost-effective way to obtain a large quantity of wood.

Sawmill Operations and Byproducts

If you have access to a sawmill, you can take advantage of sawmill byproducts, such as slabs and edgings, for firewood.

Slabs: These are the outer pieces of wood that are cut off the log. They typically have bark on one side.
Edgings: These are the narrow strips of wood that are cut off the sides of the log.

Slabs and edgings are often available at a discounted price compared to whole logs. They’re a great option for firewood.

Seasoning and Kiln Drying

While air drying is the most common method of drying firewood, kiln drying is a faster and more efficient option.

Kiln Drying: Kiln drying involves heating the wood in a controlled environment to remove moisture. This process can dry firewood in a matter of days or weeks.
Cost Considerations: Kiln drying is more expensive than air drying.

I’ve experimented with kiln drying small batches of firewood. It’s a great way to get dry firewood quickly, but it’s not cost-effective for large-scale operations.

Sustainable Firewood Harvesting

It’s important to harvest firewood sustainably to ensure the long-term health of our forests.

Selective Harvesting: Avoid clear-cutting. Instead, practice selective harvesting, which involves removing only certain trees from the forest.
Leave Seed Trees: Leave seed trees to help regenerate the forest.
Avoid Harvesting in Sensitive Areas: Avoid harvesting in sensitive areas, such as wetlands and riparian zones.
Follow Local Regulations: Follow all local regulations regarding firewood harvesting.

I always obtain the necessary permits before harvesting firewood.

Conclusion: The Art of Firewood
