Stihl 012 AV Chainsaw (5 Pro Tips for Wood Cutting)

Have you ever savored the smoky aroma of a perfectly seasoned log crackling in your fireplace, a warmth that seems to penetrate not just the room but your very soul? That’s more than just burning wood; it’s an art, a science, and a connection to a tradition that stretches back millennia. Today, I want to share some insights gleaned from years of working with wood, focusing particularly on getting the most out of a classic: the Stihl 012 AV chainsaw.

The Stihl 012 AV: A Timeless Workhorse

The Stihl 012 AV chainsaw might not be the newest kid on the block, but like a well-aged whiskey, it’s a tool that has proven its worth time and again. It’s a lightweight, easy-to-handle saw that’s perfect for smaller jobs around the yard, felling small trees, or bucking firewood. While it may not have the raw power of its larger cousins, its simplicity and reliability make it a favorite among homeowners and seasoned woodcutters alike.

But even the best tools need the right technique to truly shine. So, let’s dive into five pro tips to help you maximize your wood-cutting efficiency and safety with the Stihl 012 AV.

Pro Tip 1: Sharpening – The Key to Effortless Cutting

Why Sharpening Matters

A dull chain is not only inefficient, but it’s also dangerous. It forces you to apply more pressure, increasing the risk of kickback and putting unnecessary strain on both you and the saw. A sharp chain, on the other hand, glides through wood with ease, reducing fatigue and improving cutting accuracy. In my experience, a well-sharpened chain can reduce cutting time by as much as 30%, saving you valuable time and fuel.

The Sharpening Process: A Step-by-Step Guide

Sharpening a chainsaw chain might seem daunting at first, but with a little practice, it becomes second nature. Here’s a breakdown of the process:

1. Gather Your Tools: You’ll need a chainsaw file (typically 5/32″ for the Stihl 012 AV, but always check your chain’s specifications), a file guide, a depth gauge tool, and a flat file.

2. Secure the Saw: Clamp the chainsaw bar in a vise or use a bar clamp to keep it steady. This allows for more precise and consistent filing.

3. Identify the Correct Filing Angle: The correct filing angle is crucial for optimal cutting performance. Check your chain manufacturer’s specifications, but typically, it’s around 30 degrees. The file guide will help you maintain this angle.

4. File Each Cutter: Using smooth, even strokes, file each cutter from the inside out. Maintain a consistent angle and pressure. Count your strokes per cutter to ensure uniformity. Typically, 3-5 strokes per cutter is sufficient.

5. Check and Adjust Depth Gauges: The depth gauges (also known as rakers) control how much the cutter bites into the wood. Use a depth gauge tool to check the height of the depth gauges. If they are too high, use a flat file to carefully lower them.

6. Test Your Work: After sharpening, test the chain on a piece of softwood. A properly sharpened chain will produce long, thin shavings. If it produces dust or requires excessive pressure, you may need to refine your sharpening technique.

My Personal Sharpening Story

I remember one particularly frustrating day when I was trying to fell a small oak tree with a dull chain. I struggled for hours, sweating and straining, only to make slow progress. Finally, I stopped, took the time to properly sharpen the chain, and the difference was night and day. The saw sliced through the oak like butter, and I finished the job in a fraction of the time. That day, I learned the true value of a sharp chain and the importance of regular maintenance.

Data-Backed Insight

Studies have shown that a properly maintained chainsaw can increase cutting efficiency by up to 40%. This translates to less fuel consumption, reduced wear and tear on the saw, and a significant decrease in operator fatigue. Furthermore, a sharp chain reduces the risk of kickback by allowing the saw to cut smoothly and efficiently.

Pro Tip 2: Mastering the Felling Cut

Understanding Wood Anatomy

Before felling any tree, it’s essential to understand the basics of wood anatomy. Trees are composed of several layers, including the bark, cambium, sapwood, and heartwood. The sapwood is the living part of the tree, responsible for transporting water and nutrients. The heartwood is the dead, inner part of the tree, providing structural support.

Hardwoods, like oak and maple, have a more complex cellular structure than softwoods, like pine and fir. This makes them denser and more difficult to cut. Understanding these differences can help you choose the right cutting technique and adjust your saw accordingly.

The Felling Process: A Safe and Controlled Approach

Felling a tree is a serious undertaking that requires careful planning and execution. Here’s a breakdown of the process:

1. Assess the Tree and Surroundings: Before making any cuts, carefully assess the tree’s lean, wind direction, and any potential hazards, such as power lines or buildings. Clear the area around the tree of any obstacles and create a clear escape path.

2. The Notch Cut: The notch cut (also known as the face cut) determines the direction in which the tree will fall. It consists of two cuts: an upper cut at a 45-degree angle and a lower, horizontal cut that meets the upper cut. The notch should be about one-third of the tree’s diameter.

3. The Back Cut: The back cut is made on the opposite side of the tree from the notch. It should be slightly higher than the horizontal cut of the notch. Leave a hinge of uncut wood between the back cut and the notch. This hinge will help control the tree’s fall.

4. Wedges: As you make the back cut, insert wedges into the cut to prevent the tree from pinching the saw bar. Wedges also help to direct the tree’s fall.

5. The Final Push: Once the back cut is nearly complete, give the tree a final push with a felling lever or by hand. Stand clear of the tree as it falls.

My Close Call

I once underestimated the lean of a tree and nearly had it fall in the wrong direction. Fortunately, I was able to use a felling lever to correct its course, but it was a close call that taught me the importance of careful assessment and planning.

Data-Backed Insight

According to the Occupational Safety and Health Administration (OSHA), logging is one of the most dangerous occupations in the United States. Proper training and adherence to safety protocols are essential to prevent accidents and injuries. Statistics show that the majority of logging accidents are caused by improper felling techniques and a lack of situational awareness.

Pro Tip 3: Bucking for Efficiency

Optimizing Cut Lengths

Bucking, or cutting felled trees into smaller, manageable lengths, is a crucial step in firewood preparation. Optimizing cut lengths can significantly improve your efficiency and reduce waste.

The ideal length for firewood depends on the size of your fireplace or wood stove. Generally, 16-inch lengths are suitable for most applications. However, it’s always best to measure your appliance and adjust accordingly.

The Bucking Process: A Safe and Efficient Approach

1. Plan Your Cuts: Before making any cuts, plan your cuts to minimize waste and maximize the number of usable pieces. Look for knots or defects in the wood and adjust your cuts accordingly.

2. Support the Log: Use sawbucks or other supports to keep the log off the ground. This will prevent the chain from hitting the ground and dulling prematurely.

3. Make Consistent Cuts: Use a measuring stick or tape measure to ensure consistent cut lengths. This will make stacking and storing the firewood much easier.

4. Avoid Pinching: When bucking logs, be aware of the potential for pinching, where the weight of the log closes the cut and traps the saw bar. Use wedges or branches to prop up the log and prevent pinching.

My Time-Saving Trick

I’ve found that using a pre-measured stick as a guide when bucking firewood saves a tremendous amount of time. I simply mark the desired length on the stick and use it to quickly measure each cut. This ensures consistent lengths and reduces the need for constant measuring with a tape measure.

Data-Backed Insight

Studies have shown that using proper bucking techniques can increase firewood production by as much as 20%. This translates to more firewood with less effort and reduced wear and tear on your equipment. Additionally, consistent cut lengths make stacking and storing firewood more efficient, saving space and improving air circulation.

Pro Tip 4: Chain Maintenance Beyond Sharpening

Chain Lubrication: The Lifeblood of Your Saw

Proper chain lubrication is essential for extending the life of your chainsaw and ensuring optimal performance. The chain needs a constant supply of oil to reduce friction and prevent overheating.

Always use a high-quality chainsaw bar and chain oil. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication and can damage the saw. Check the oil level frequently and refill as needed. A good rule of thumb is to refill the oil tank every time you refill the fuel tank.

Cleaning and Inspection: Preventing Problems Before They Start

Regular cleaning and inspection are crucial for preventing problems and extending the life of your chainsaw. After each use, clean the saw with a brush or compressed air to remove sawdust and debris. Pay particular attention to the air filter, spark plug, and cooling fins.

Inspect the chain for damage, such as broken or bent cutters. Replace the chain if it is severely damaged or worn. Check the sprocket for wear and replace it if necessary.

My Maintenance Routine

I make it a habit to thoroughly clean and inspect my chainsaw after each use. This only takes a few minutes, but it can prevent costly repairs down the road. I also keep a log of all maintenance performed on the saw, including sharpening, oil changes, and parts replacements.

Data-Backed Insight

Studies have shown that proper chain lubrication and maintenance can extend the life of a chainsaw by as much as 50%. This translates to significant cost savings over the long term. Additionally, a well-maintained saw is more efficient and reliable, reducing downtime and improving productivity.

Pro Tip 5: Understanding Wood Moisture Content

The Science of Seasoning

The moisture content of wood plays a crucial role in its burning properties. Freshly cut wood can contain as much as 50% moisture, making it difficult to ignite and producing excessive smoke. Seasoning, or drying, wood reduces its moisture content, making it easier to burn and producing more heat.

The ideal moisture content for firewood is between 15% and 20%. This can be achieved by stacking the wood in a well-ventilated area for at least six months, or preferably a year.

How to Measure Moisture Content

You can measure the moisture content of wood using a moisture meter. These devices are relatively inexpensive and easy to use. Simply insert the probes into the wood and read the moisture content on the display.

My Seasoning Method

I prefer to stack my firewood in long, narrow rows with plenty of space between each row. This allows for maximum air circulation and speeds up the drying process. I also cover the top of the stack with a tarp to protect it from rain and snow.

Data-Backed Insight

Studies have shown that properly seasoned firewood can produce up to 30% more heat than green wood. This translates to significant fuel savings and a more efficient burning experience. Additionally, burning dry wood reduces the risk of creosote buildup in your chimney, which can cause chimney fires. Creosote is unburned wood particles that condense in the chimney, and it’s highly flammable. Burning seasoned wood minimizes this risk.

Wood Anatomy and Properties: A Deeper Dive

Let’s delve a bit deeper into wood anatomy. Understanding the structure of wood is crucial for making informed decisions about cutting, splitting, and seasoning.

Hardwood vs. Softwood: The Key Differences

Hardwoods and softwoods differ significantly in their cellular structure and density. Hardwoods, like oak, maple, and birch, have a more complex cellular structure, with smaller cells and thicker cell walls. This makes them denser and more difficult to cut. Softwoods, like pine, fir, and spruce, have a simpler cellular structure, with larger cells and thinner cell walls. This makes them less dense and easier to cut.

Density and Heat Value

The density of wood is directly related to its heat value. Denser woods, like oak and maple, contain more energy per unit volume than less dense woods, like pine and fir. This means that you’ll need less hardwood to produce the same amount of heat as softwood.

Here’s a general comparison of the heat value of different types of wood:

• Oak: High heat value, long burning time
• Maple: High heat value, long burning time
• Birch: Medium heat value, medium burning time
• Ash: High heat value, long burning time, easy to split
• Pine: Low heat value, short burning time, produces more smoke

Wood Grain and Splitting

The grain of wood also affects its splitting properties. Straight-grained wood, like ash and oak, is easier to split than wood with knots or twisted grain. Splitting wood along the grain is much easier than splitting against the grain.

Logging Tool Selection and Maintenance Best Practices

Beyond the chainsaw, several other tools are essential for efficient and safe wood processing. Let’s explore some of these tools and best practices for their maintenance.

Axes and Splitting Mauls

Axes and splitting mauls are used for splitting logs into smaller pieces. Axes are designed for chopping, while splitting mauls are designed for splitting. Choose a splitting maul with a weight that you can comfortably swing for extended periods.

Maintenance: Keep the blade of your axe or splitting maul sharp. Use a file or sharpening stone to maintain the edge. Inspect the handle for cracks or damage and replace it if necessary.

Wedges and Sledges

Wedges are used to help split stubborn logs. Drive the wedge into the log with a sledgehammer. Use multiple wedges if necessary.

Maintenance: Inspect wedges for damage, such as cracks or mushrooming. Replace damaged wedges immediately. Keep the striking face of the sledgehammer clean and free of debris.

Sawbucks

Sawbucks are used to support logs while bucking. They make it easier and safer to cut logs to the desired length.

Maintenance: Inspect sawbucks for damage, such as broken or loose supports. Repair or replace damaged sawbucks as needed.

Personal Protective Equipment (PPE)

Personal protective equipment (PPE) is essential for protecting yourself from injury while working with wood. Always wear the following PPE:

• Safety Glasses: To protect your eyes from flying debris.
• Hearing Protection: To protect your ears from the noise of the chainsaw.
• Gloves: To protect your hands from cuts and abrasions.
• Steel-Toed Boots: To protect your feet from falling logs and sharp objects.
• Chainsaw Chaps: To protect your legs from chainsaw cuts.
• Helmet: To protect your head from falling branches or logs.

Maintenance: Inspect your PPE regularly for damage and replace it as needed.

Firewood Seasoning Techniques and Safety Considerations

Seasoning firewood properly is essential for efficient burning and safety. Let’s explore some key techniques and safety considerations.

Stacking Methods

The way you stack your firewood can significantly affect its drying time. Here are some popular stacking methods:

• Rows: Stacking firewood in long, narrow rows with plenty of space between each row allows for maximum air circulation.
• Circular Stacks: Circular stacks are visually appealing and can be more stable than rows. However, they may not provide as much air circulation.
• Crib Stacks: Crib stacks are built like a log cabin, with alternating layers of wood. They are very stable and provide good air circulation.

Covering Firewood

Covering your firewood can protect it from rain and snow, which can slow down the drying process. However, it’s important to allow for adequate ventilation to prevent mold and mildew.

Use a tarp to cover the top of the stack, but leave the sides open for air circulation. You can also use a woodshed or other covered structure to protect your firewood.

Safety Considerations

• Stacking Stability: Stack your firewood on a level surface to prevent it from toppling over.
• Pest Control: Keep your firewood away from your house to prevent pests, such as termites and carpenter ants, from infesting your home.
• Fire Safety: Keep a fire extinguisher or water hose nearby when burning firewood. Never leave a fire unattended.
