Stihl 193 Chainsaws: 5 Pro Tips for Maximizing Firewood Prep

The global demand for firewood remains surprisingly robust. While renewable energy sources are gaining traction, firewood continues to be a primary heating source for millions, especially in rural areas and developing nations. Recent statistics show that the global firewood market is projected to reach a value of over $30 billion by 2027. This demand underscores the importance of efficient and sustainable firewood preparation techniques, and the Stihl 193, with its lightweight design and reliable performance, is a popular choice for many.

Understanding the Stihl 193: A Brief Overview

Before diving into the tips, let’s quickly recap the Stihl 193. This chainsaw is known for its lightweight design, making it ideal for smaller tasks and extended use without excessive fatigue. It’s a popular choice for homeowners and hobbyists who need a reliable saw for limbing, small tree felling, and, of course, firewood preparation.

However, it’s essential to remember that the Stihl 193 isn’t a heavy-duty logging saw. It has limitations in terms of bar length and engine power. Understanding these limitations is crucial for safe and efficient operation.

Pro Tip #1: Chain Selection and Maintenance – The Heart of the Matter

Your chainsaw is only as good as its chain. Selecting the right chain and maintaining it properly is paramount for efficient firewood prep. Think of it like this: a dull chain is like trying to cut butter with a spoon – frustrating and ineffective.

Choosing the Right Chain

The Stihl 193 typically uses a low-profile chain, often a 3/8″ Picco Micro (PM3) or Picco Duro (PD3). The PM3 is a great all-around chain for general use, while the PD3, with its carbide-tipped cutters, offers superior durability and longer cutting life, especially when dealing with dirty or abrasive wood.

Key Considerations:

Wood Type: For softer woods like pine and fir, the PM3 is usually sufficient. However, for hardwoods like oak or maple, or if you’re cutting wood that’s been lying on the ground and is likely to be dirty, the PD3 is a worthwhile investment.
Chain Pitch and Gauge: Ensure the chain pitch and gauge match your Stihl 193’s specifications. Using the wrong chain can damage your saw and compromise safety. Refer to your owner’s manual for the correct specifications.
Low-Kickback Features: Consider chains with low-kickback features, especially if you’re a beginner. These chains are designed to reduce the risk of kickback, a dangerous and potentially fatal occurrence.

Chain Maintenance: Sharpening and Lubrication

A sharp chain is a safe chain. A dull chain requires more force to cut, increasing the risk of kickback and putting unnecessary strain on your saw’s engine.

Sharpening:

Frequency: Sharpen your chain every time you refuel, or more often if you notice it’s cutting slower or producing fine sawdust instead of chips.
Tools: You can sharpen your chain with a file and guide, or with a motorized chain sharpener. A file and guide is more portable and allows for precise sharpening, while a motorized sharpener is faster and easier to use, especially for beginners.
Technique: Maintain the correct filing angle and depth. The angle is usually marked on the file guide. File each cutter evenly, removing the same amount of material from each.
Depth Gauges: Check and adjust the depth gauges (rakers) periodically. These control the amount of wood each cutter takes. If they’re too high, the chain won’t cut effectively. If they’re too low, the chain will grab and cause kickback.

Lubrication:

Chain Oil: Use a high-quality chain oil specifically designed for chainsaws. This will keep the chain lubricated, reducing friction and wear.
Oil Level: Check the oil level frequently and refill as needed. Never run your chainsaw without chain oil.
Oil Flow: Ensure the oiler is functioning properly. A clogged oiler can lead to premature chain wear and damage to the bar.

My Experience: I once neglected to properly sharpen my chain before tackling a large pile of oak logs. The saw struggled, the chain smoked, and I ended up spending twice as long on the task. Lesson learned: a sharp chain is worth its weight in gold.

Pro Tip #2: Felling Small Trees Safely and Efficiently

The Stihl 193 is well-suited for felling smaller trees, but safety should always be your top priority. Felling a tree, even a small one, can be dangerous if not done correctly.

Assessing the Tree and Surroundings

Before making a single cut, take the time to assess the tree and its surroundings.

Tree Lean: Determine the tree’s natural lean. It will generally fall in the direction of the lean.
Wind Direction: Wind can significantly affect the tree’s fall. Avoid felling trees in high winds.
Obstacles: Identify any obstacles that could interfere with the tree’s fall, such as power lines, buildings, or other trees.
Escape Route: Plan a clear escape route at a 45-degree angle away from the direction of the fall.

Felling Techniques

Notch Cut: The notch cut determines the direction of the fall. It should be a V-shaped cut, about 1/3 of the tree’s diameter.
Hinge: Leave a hinge of uncut wood between the notch cut and the back cut. The hinge controls the fall of the tree.
Back Cut: The back cut should be slightly higher than the notch cut. Do not cut completely through the tree. Leave the hinge intact.
Wedges: If the tree is leaning in the wrong direction, use wedges to help guide its fall. Drive the wedges into the back cut to lift the tree and encourage it to fall in the desired direction.

Step-by-Step Guide:

Clear the area around the tree. Remove any brush or debris that could impede your movement.
Make the notch cut. Aim for a 45-degree angle, cutting about 1/3 of the way into the tree.
Make the back cut. Cut from the opposite side of the tree, slightly higher than the notch cut.
Insert wedges (if needed). Drive the wedges into the back cut to help guide the fall.
Shout a warning. Let everyone in the area know that the tree is about to fall.
Retreat along your escape route. Keep your eye on the falling tree and be prepared to move quickly if necessary.

Data Point: According to the Occupational Safety and Health Administration (OSHA), improper felling techniques are a leading cause of logging accidents. Proper training and adherence to safety guidelines can significantly reduce the risk of injury.

Pro Tip #3: De-limbing Like a Pro – Efficiency and Safety Combined

De-limbing, or removing branches from a felled tree, can be a time-consuming and potentially dangerous task. Here’s how to do it safely and efficiently with your Stihl 193.

Proper Stance and Grip

Stable Base: Maintain a wide, stable stance. Keep your feet firmly planted on the ground.
Firm Grip: Use a firm grip on the chainsaw with both hands. Keep your thumbs wrapped around the handles.
Body Position: Position yourself to avoid being hit by falling branches. Work from the uphill side of the tree if possible.

De-limbing Techniques

Cut from the Top: Start by cutting the branches on the top side of the tree. This will prevent the saw from binding.
Cut Close to the Trunk: Cut the branches as close to the trunk as possible without damaging the bark.
Support the Branch: Support the branch with your hand or foot before cutting it. This will prevent it from pinching the saw.
Avoid Cutting from Below: Avoid cutting branches from below, as this increases the risk of kickback.

Case Study: I once watched a seasoned logger de-limb a tree in what seemed like record time. His secret? He used a systematic approach, working from the top down and always supporting the branches before cutting. He also kept his chain razor-sharp.

Avoiding Pinching

Pinching occurs when the weight of the branch closes the cut, trapping the saw. To avoid pinching:

Cut on the Compression Side: Cut on the side of the branch that is under compression. This will allow the cut to open up.
Use Wedges: Use wedges to keep the cut open if necessary.
Cut in Stages: For larger branches, cut in stages, removing small sections at a time.

Pro Tip #4: Bucking for Firewood – Mastering the Art of Log Cutting

Bucking is the process of cutting logs into smaller, manageable lengths for firewood. This is where the Stihl 193 really shines, especially for smaller diameter logs.

Determining Log Length

Fireplace Size: The ideal log length depends on the size of your fireplace or wood stove. Measure the firebox and subtract a few inches to allow for air circulation.
Ease of Handling: Consider the weight and ease of handling. Shorter logs are easier to lift and stack.
Common Lengths: Common firewood lengths range from 12 to 24 inches.

Safe Bucking Practices

Stable Log: Ensure the log is stable and won’t roll or shift during cutting. Use log supports or sawbucks to elevate the log.
Clear Area: Clear the area around the log of any obstacles.
Proper Stance: Maintain a wide, stable stance and keep your hands firmly on the chainsaw.

Bucking Techniques

Cut from the Top: Start by cutting from the top of the log, about halfway through.
Roll the Log: Roll the log over and finish the cut from the opposite side.
Avoid Cutting into the Ground: Avoid cutting into the ground, as this can dull the chain.

Dealing with Compression and Tension

Just like with de-limbing, compression and tension can cause pinching during bucking.

Compression: The top of the log is under compression. Cut from the top first.
Tension: The bottom of the log is under tension. Cut from the bottom last.

Troubleshooting: If the saw starts to pinch, stop cutting and insert a wedge into the cut to relieve the pressure.

Pro Tip #5: Seasoning and Storing Firewood – The Final Step to a Warm Winter

Preparing firewood isn’t just about cutting wood; it’s also about properly seasoning and storing it. Seasoning is the process of drying wood to reduce its moisture content. Properly seasoned firewood burns hotter, cleaner, and produces less smoke.

Why Season Firewood?

Increased Heat Output: Seasoned firewood has a lower moisture content, which means more of the energy is used to heat your home and less is used to evaporate water.
Reduced Smoke: Seasoned firewood produces less smoke, which is better for your health and the environment.
Easier to Ignite: Seasoned firewood is easier to ignite and burns more consistently.
Reduced Creosote Buildup: Seasoned firewood reduces creosote buildup in your chimney, which can prevent chimney fires.

Data Point: Green wood can have a moisture content of 50% or higher. Seasoned firewood should have a moisture content of 20% or less.

Seasoning Techniques

Split the Wood: Splitting the wood increases the surface area, allowing it to dry faster.
Stack the Wood: Stack the wood in a single row, with gaps between the logs to allow for air circulation.
Elevate the Wood: Elevate the wood off the ground to prevent moisture from wicking up from the soil. Use pallets or cinder blocks.
Cover the Wood: Cover the top of the woodpile with a tarp to protect it from rain and snow. Leave the sides open to allow for air circulation.
Location: Choose a sunny, windy location for your woodpile.

Drying Time

The drying time depends on the type of wood, the climate, and the seasoning techniques used.

Softwoods: Softwoods like pine and fir typically take 6-12 months to season.
Hardwoods: Hardwoods like oak and maple typically take 12-24 months to season.

My Story: I once rushed the seasoning process, thinking I could get away with burning slightly green wood. The result? A smoky, inefficient fire that barely heated my house.

Storing Firewood

Dry Location: Store firewood in a dry location, away from moisture.
Covered Storage: Store firewood in a covered shed or under a tarp.
Elevated Storage: Elevate the firewood off the ground to prevent moisture from wicking up from the soil.
Ventilation: Ensure adequate ventilation to prevent mold and mildew growth.

Costs, Budgeting, and Resource Management

Firewood preparation involves costs, and it’s wise to consider them.

Chainsaw Costs: The Stihl 193 is a relatively affordable chainsaw, but factor in maintenance costs, such as chain sharpening, oil, and spark plugs.
