Wood Processing and Firewood Industry: A Global Overview

Before we get into the nitty-gritty, let’s take a quick look at the bigger picture. Globally, the wood processing and firewood industry is a substantial market. In 2023, the global firewood market was estimated at around $12 billion and is expected to see steady growth as energy prices fluctuate and demand for sustainable heating solutions rises. Similarly, the global market for logging tools, including chainsaws, is projected to reach over $5 billion by 2028, driven by both professional logging operations and individual homeowners managing their properties.

These figures aren’t just numbers; they represent countless individuals and businesses relying on these tools and techniques every single day. Whether you’re a small-scale firewood producer or simply managing your own woodland, understanding best practices in wood processing is essential for efficiency, safety, and sustainability.

Mastering the Husqvarna 137e: 7 Pro Woodcutting Hacks (and Beyond!)

Here are my top tips for maximizing the performance and lifespan of your Husqvarna 137e, along with bonus insights and advice drawn from my own experiences.

1. Chain Tension: The Key to Smooth Cuts and Saw Longevity

Why it Matters: Proper chain tension is the most critical factor in chainsaw operation. Too loose, and the chain can derail, causing damage to the saw and potential injury. Too tight, and you’ll wear out the bar, chain, and even the engine prematurely.

The Hack:

1. Check Before Every Use: Before starting your saw, always check the chain tension.
2. Warm-Up Adjustment: After the first few cuts, recheck the tension. The chain expands as it heats up.
3. The “Pull-Away” Test: With the saw off and wearing gloves, pull the chain away from the bar at the midpoint on the bottom. You should be able to pull the chain out slightly, but not so far that the drive links (the teeth that fit into the bar) come completely out of the bar groove.
4. Tighten or Loosen: Use the chain tensioning screw (usually located on the side of the saw) to adjust. Turn clockwise to tighten, counterclockwise to loosen.
5. Lock it Down: Once you’ve got the right tension, tighten the bar nuts securely.

My Experience: I once ignored a slightly loose chain on a particularly long day of bucking firewood. Within an hour, the chain had derailed three times, and the bar was noticeably worn. I learned my lesson the hard way – a few seconds of checking tension can save you hours of frustration and costly repairs.

Data Point: Studies show that maintaining proper chain tension can extend the life of your chainsaw bar by up to 30%.

2. Sharpening: Turning Dull Chains into Cutting Machines

Why it Matters: A sharp chain cuts faster, safer, and with less effort. A dull chain forces you to push harder, increasing the risk of kickback and putting unnecessary strain on the saw.

The Hack:

1. Recognize Dullness: If you have to force the saw through the wood, or if it produces fine sawdust instead of wood chips, your chain is dull.
2. Invest in a Sharpener: I recommend a good quality chainsaw file and a filing guide for consistent results. Consider an electric sharpener if you’re sharpening frequently.
3. The 30/10 Rule: File the cutting teeth at a 30-degree angle and the depth gauges (rakers) about 10 degrees lower. Use your filing guide to maintain these angles.
4. Consistent Strokes: Use smooth, consistent strokes, filing from the inside of the tooth outwards.
5. Equal Filing: File each tooth the same amount to maintain balance and prevent the saw from pulling to one side.
6. Depth Gauge Adjustment: After sharpening several times, you’ll need to lower the depth gauges (rakers). Use a depth gauge tool and a flat file.
7. Frequency: Sharpen your chain every time you refuel, or more often if you’re cutting dirty or abrasive wood.

My Experience: I used to dread sharpening my chains, but once I invested in a quality filing guide and learned the proper technique, it became a quick and almost meditative process. Plus, the difference in cutting performance is night and day!

Data Point: A properly sharpened chainsaw can cut through wood up to 50% faster than a dull one.

3. Fuel and Oil: The Lifeblood of Your 137e

Why it Matters: Using the correct fuel mixture and bar oil is essential for engine lubrication and chain performance.

The Hack:

1. Fuel Mixture: The Husqvarna 137e typically requires a 50:1 fuel-to-oil ratio (50 parts gasoline to 1 part 2-stroke oil). Always use high-quality, fresh gasoline with an octane rating of 89 or higher.
2. High-Quality 2-Stroke Oil: Use a premium 2-stroke oil specifically designed for air-cooled engines. Husqvarna’s own brand is a good option, but any reputable brand will do.
3. Mixing is Key: Mix the fuel and oil thoroughly in a separate container before pouring it into the saw’s fuel tank.
4. Bar Oil: Use a good quality bar and chain oil to lubricate the chain and bar. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication and can damage the saw.
5. Check Levels: Regularly check the fuel and bar oil levels during use. Never let the bar oil run dry.
6. Storage: If you’re not going to use the saw for an extended period, drain the fuel tank and run the saw until it stalls to prevent fuel from gumming up the carburetor.

My Experience: I once tried to save a few bucks by using a cheaper 2-stroke oil. The saw ran rough, produced excessive smoke, and eventually fouled the spark plug. Lesson learned – always use quality fuel and oil!

Data Point: Using the correct fuel mixture and bar oil can extend the life of your chainsaw engine by up to 25%.

4. Starting Problems: Diagnosing and Solving the Mystery

Why it Matters: A chainsaw that won’t start is useless. Understanding common starting problems and how to fix them can save you time and frustration.

The Hack:

1. Check the Basics: Make sure the fuel tank is full, the on/off switch is in the “on” position, and the chain brake is disengaged.
2. Choke: Use the choke to start the saw when the engine is cold. Once the engine starts, immediately turn off the choke.
3. Priming: Press the primer bulb (if equipped) several times to prime the carburetor.
4. Pull the Cord: Pull the starter cord firmly and smoothly. Avoid yanking it, as this can damage the starter mechanism.
5. Flooded Engine: If the engine floods (smells strongly of gasoline), remove the spark plug, pull the starter cord several times to clear the cylinder, and then reinstall the spark plug.
6. Spark Plug: Check the spark plug for fouling or damage. Clean or replace the spark plug as needed. The gap should be 0.5mm.
7. Air Filter: A dirty air filter can restrict airflow and prevent the engine from starting. Clean or replace the air filter regularly.
8. Fuel Filter: A clogged fuel filter can also prevent the engine from starting. Replace the fuel filter as needed.

My Experience: I had a Husqvarna 137e that refused to start one cold morning. After checking everything, I discovered that the spark plug was fouled with carbon buildup. A quick cleaning with a wire brush, and the saw fired right up.

Data Point: Fouled spark plugs are a common cause of starting problems in 2-stroke engines, accounting for up to 40% of non-start issues.

5. Safe Cutting Techniques: Protecting Yourself and Your Saw

Why it Matters: Chainsaw safety is paramount. Using proper cutting techniques can reduce the risk of injury and prevent damage to your saw.

The Hack:

1. Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, gloves, chainsaw chaps, and sturdy boots. A helmet is also highly recommended.
2. Stance: Maintain a stable stance with your feet shoulder-width apart.
3. Grip: Grip the saw firmly with both hands. Keep your thumbs wrapped around the handles.
4. Kickback Zone: Be aware of the kickback zone (the upper portion of the bar tip). Avoid cutting with this area, as it can cause the saw to kick back violently.
5. Cutting Techniques: Use proper cutting techniques for felling trees, limbing, and bucking.
   • Felling: Plan your escape route, undercut the tree, and then make the back cut. Use wedges to prevent the tree from pinching the bar.
   • Limbing: Work from the base of the tree towards the top. Keep the tree between you and the saw.
   • Bucking: Support the log to prevent it from pinching the bar. Use a sawhorse or other support.
6. Chain Brake: Always engage the chain brake when moving the saw or when not actively cutting.
7. Clearance: Keep the area around you clear of obstacles and bystanders.

My Experience: I once witnessed a near-miss when a fellow firewood cutter ignored the kickback zone and the saw kicked back, nearly striking him in the face. He was lucky to escape with only a minor cut, but it was a stark reminder of the importance of safety.

Data Point: Studies show that wearing proper PPE can reduce the risk of chainsaw injuries by up to 80%.

6. Wood Selection: Choosing the Right Wood for Your Needs

Why it Matters: Different types of wood have different burning characteristics and heat values. Choosing the right wood can make a big difference in your firewood performance.

The Hack:

1. Hardwoods vs. Softwoods: Hardwoods (oak, maple, ash, beech) are denser and burn longer and hotter than softwoods (pine, fir, spruce).
2. Heat Value: The heat value of wood is measured in BTUs (British Thermal Units). Hardwoods typically have a higher BTU rating than softwoods.
3. Seasoning: Always season firewood before burning it. Green wood contains a high moisture content, which reduces its heat value and produces excessive smoke.
4. Seasoning Time: Season firewood for at least six months, or preferably a year.
5. Moisture Content: Aim for a moisture content of 20% or less for optimal burning. Use a moisture meter to check the moisture content.
6. Storage: Store firewood in a well-ventilated area, off the ground, and covered to protect it from rain and snow.

My Experience: I once made the mistake of burning green pine in my wood stove. It produced a lot of smoke, very little heat, and coated the chimney with creosote, increasing the risk of a chimney fire.

Data Point: Properly seasoned firewood can produce up to 50% more heat than green wood.

7. Maintenance: Keeping Your 137e Running Smoothly

Why it Matters: Regular maintenance is essential for extending the life of your chainsaw and ensuring its reliable performance.

The Hack:

1. Air Filter Cleaning: Clean the air filter regularly with warm, soapy water. Allow it to dry completely before reinstalling.
2. Spark Plug Inspection: Inspect the spark plug regularly for fouling or damage. Clean or replace as needed.
3. Bar Cleaning: Clean the bar groove regularly with a scraper or screwdriver to remove sawdust and debris.
4. Bar Oiling: Make sure the bar oiler is working properly. Check the oil outlet on the bar and clean it if necessary.
5. Chain Sharpening: Sharpen the chain regularly, as described above.
6. Fuel System Maintenance: Periodically inspect the fuel lines and fuel filter for cracks or clogs. Replace as needed.
7. Carburetor Adjustment: If the engine is running poorly, you may need to adjust the carburetor. Consult the owner’s manual for instructions.
8. Storage: When storing the saw for an extended period, drain the fuel tank, run the saw until it stalls, and clean the saw thoroughly. Store the saw in a dry place.

My Experience: I neglected to clean the air filter on my chainsaw for too long, and the engine started running rough and losing power. A simple air filter cleaning restored the saw to its original performance.

Data Point: Regular maintenance can extend the life of your chainsaw by up to 50%.

Bonus Tips and Tricks for Woodcutting Success

Now that we’ve covered the core hacks, let’s dive into some additional tips and tricks that I’ve learned over the years.

Understanding Green Wood vs. Seasoned Wood

Green Wood: This is freshly cut wood with a high moisture content (often above 50%). Burning green wood is inefficient, produces less heat, and creates a lot of smoke and creosote, which can be dangerous.

Seasoned Wood: This wood has been allowed to dry for several months, reducing the moisture content to 20% or less. Seasoned wood burns hotter, cleaner, and more efficiently.

How to Season Wood Properly:

1. Split the Wood: Splitting the wood increases the surface area exposed to air, speeding up the drying process.
2. Stack the Wood: Stack the wood in a single row, with gaps between the pieces to allow for air circulation.
3. Elevate the Wood: Place the wood on pallets or other supports to keep it off the ground and prevent moisture from wicking up.
4. Cover the Top: Cover the top of the woodpile with a tarp or roof to protect it from rain and snow, but leave the sides open for ventilation.
5. Location: Choose a sunny, windy location for your woodpile.

Chainsaws vs. Axes: Choosing the Right Tool

While chainsaws are powerful and efficient for cutting large volumes of wood, axes still have their place in wood processing.

Chainsaws:

• Pros: Fast, efficient for cutting large trees and logs, versatile for felling, limbing, and bucking.
• Cons: Requires fuel and maintenance, can be dangerous if not used properly, noisy.

Axes:

• Pros: Simple, reliable, quiet, good for splitting small logs and kindling, requires no fuel.
• Cons: Slower and more physically demanding than chainsaws, not suitable for cutting large trees.

When to Use a Chainsaw vs. an Axe:

• Chainsaw: Use for felling trees, bucking large logs, limbing, and any task that requires cutting a lot of wood quickly.
• Axe: Use for splitting small logs and kindling, removing small branches, and any task where you want to avoid the noise and complexity of a chainsaw.

Case Study: Optimizing Firewood Drying

I once conducted a small experiment to compare different firewood drying methods. I split and stacked three piles of oak firewood:

• Pile 1: Stacked directly on the ground, uncovered.
• Pile 2: Stacked on pallets, uncovered.
• Pile 3: Stacked on pallets, covered with a tarp.

After six months, I measured the moisture content of each pile using a moisture meter.

• Pile 1: Average moisture content of 35%.
• Pile 2: Average moisture content of 25%.
• Pile 3: Average moisture content of 18%.

The results clearly showed that stacking the wood on pallets and covering it with a tarp significantly improved the drying rate and resulted in drier firewood.
