The MS 362 had approximately 17% lower vibration levels than the MS 391. This can make a significant difference during extended use, reducing fatigue and the risk of vibration-related injuries.

Actionable Tips for Wood Processing and Firewood Preparation

Now that we’ve compared the MS 362 and MS 391, let’s move on to some actionable tips for wood processing and firewood preparation.

1. Safety First

Safety should always be your top priority when working with chainsaws and other wood processing tools. Always wear appropriate personal protective equipment (PPE), including:

• Chainsaw-resistant chaps or pants: These protect your legs from accidental cuts.
• Steel-toed boots: Protect your feet from falling logs and sharp objects.
• 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.
• Gloves: Provide a better grip and protect your hands from cuts and splinters.
• Hard hat: Protects your head from falling branches or trees.

Before starting any work, inspect your chainsaw and ensure that it’s in good working condition. Check the chain tension, oil level, and fuel level. Make sure the chain brake is functioning properly.

2. Felling Trees Safely

Felling trees can be dangerous, so it’s essential to follow safe practices.

Step 1: Assess the Tree and Surroundings

Before you start cutting, assess the tree for any signs of weakness or decay. Look for dead branches, cracks in the trunk, or leaning. Also, check the surrounding area for obstacles such as power lines, buildings, or roads.

Step 2: Plan Your Escape Route

Before you start cutting, plan your escape route. You should have a clear path away from the tree in case it falls unexpectedly.

Step 3: Make the Notch Cut

The notch cut determines the direction the tree will fall. It should be made on the side of the tree facing the direction you want it to fall. The notch should be about one-third of the tree’s diameter.

Step 4: Make the Back Cut

The back cut is made on the opposite side of the tree from the notch cut. It should be slightly higher than the bottom of the notch cut. Leave a hinge of wood between the back cut and the notch cut. This hinge will help control the direction of the fall.

Step 5: Wedge the Tree (If Necessary)

If the tree is leaning in the wrong direction or if you’re concerned about it falling prematurely, you can use a felling wedge to help guide the fall. Insert the wedge into the back cut and tap it with a hammer or axe to force the tree to fall in the desired direction.

Step 6: Monitor the Fall

As the tree begins to fall, move away from the tree along your planned escape route. Watch the tree carefully and be prepared to react if it falls unexpectedly.

3. De-Limbing Procedures

After felling a tree, you’ll need to remove the branches. This is called de-limbing.

Step 1: Position Yourself Safely

Stand on the uphill side of the tree and work your way down. This will help prevent the tree from rolling on top of you.

Step 2: Use a Firm Stance

Maintain a firm stance and keep your feet planted firmly on the ground.

Step 3: Cut Branches Close to the Trunk

Cut the branches as close to the trunk as possible. This will make the wood easier to process later.

Step 4: Be Aware of Kickback

Kickback is a sudden, uncontrolled movement of the chainsaw that can cause serious injury. To avoid kickback, avoid cutting with the tip of the bar and keep the chain sharp.

4. Splitting Logs

Splitting logs is an essential part of firewood preparation.

Step 1: Choose the Right Tool

There are several tools you can use to split logs, including:

• Axe: A traditional tool for splitting logs. It’s best for smaller logs and seasoned wood.
• Splitting Maul: A heavier version of the axe, designed for splitting larger logs.
• Hydraulic Log Splitter: A powered machine that uses hydraulic pressure to split logs. It’s the most efficient option for splitting large quantities of wood.

Step 2: Position the Log

Place the log on a solid surface, such as a chopping block or a stump.

Step 3: Aim for the Center

Aim for the center of the log and swing the axe or maul with a controlled motion.

Step 4: Use Wedges (If Necessary)

If the log is difficult to split, you can use wedges to help. Drive the wedges into the cracks with a hammer or maul.

5. Seasoning Firewood

Seasoning firewood is crucial for efficient burning. Green wood contains a high moisture content, which makes it difficult to ignite and produces a lot of smoke. Seasoned wood, on the other hand, burns hotter and cleaner.

Step 1: Split the Wood

Splitting the wood increases the surface area, which allows it to dry more quickly.

Step 2: Stack the Wood Properly

Stack the wood in a well-ventilated area, such as a sunny location with good airflow. Leave space between the rows of wood to allow air to circulate.

Step 3: Cover the Wood (Optional)

If you live in a rainy area, you can cover the top of the woodpile with a tarp to protect it from the rain. However, make sure to leave the sides open to allow air to circulate.

Step 4: Allow the Wood to Dry

Allow the wood to dry for at least 6-12 months. The longer it dries, the better it will burn.

Data Point: Studies have shown that properly seasoned firewood can have a moisture content of 20% or less, compared to green wood which can have a moisture content of 50% or more. This lower moisture content results in a significant increase in burning efficiency and a reduction in smoke emissions.

6. Choosing the Right Wood Species

The type of wood you burn can also affect its burning efficiency and heat output. Hardwoods, such as oak, maple, and ash, are denser and burn longer than softwoods, such as pine and fir.

Data Point: Oak has a BTU (British Thermal Unit) rating of approximately 28 million per cord, while pine has a BTU rating of approximately 20 million per cord. This means that oak produces significantly more heat than pine.

7. Tool Maintenance

Proper tool maintenance is essential for ensuring the longevity and performance of your wood processing tools.

• Chainsaw: Clean the chainsaw regularly, sharpen the chain, and check the oil and fuel levels.
• Axe and Maul: Keep the blade sharp and free of rust.
• Log Splitter: Follow the manufacturer’s instructions for maintenance and lubrication.

Costs and Budgeting Considerations

Wood processing and firewood preparation can involve significant costs, depending on the scale of your operation. Here are some factors to consider:

• Equipment Costs: Chainsaws, axes, log splitters, and other tools can be expensive.
• Fuel and Oil Costs: Chainsaws and log splitters require fuel and oil.
• Maintenance Costs: Regular maintenance and repairs can add up over time.
• Transportation Costs: Transporting wood from the forest to your property can involve significant costs.

To minimize costs, consider:

• Buying Used Equipment: Used chainsaws and log splitters can be a good option if you’re on a tight budget.
• Renting Equipment: Renting equipment can be more cost-effective than buying if you only need it occasionally.
• Harvesting Your Own Wood: If you have access to a wooded area, you can harvest your own wood for free.
• Buying Wood in Bulk: Buying wood in bulk can save you money compared to buying it in smaller quantities.

Troubleshooting and Common Pitfalls

Even with the best planning and preparation, you may encounter problems during wood processing and firewood preparation. Here are some common pitfalls to avoid:

• Dull Chainsaw Chain: A dull chain will make it difficult to cut wood and can increase the risk of kickback.
• Improper Felling Techniques: Improper felling techniques can lead to accidents and injuries.
• Splitting Difficult Logs: Some logs are more difficult to split than others. Use wedges or a hydraulic log splitter to make the job easier.
• Storing Firewood Improperly: Storing firewood improperly can lead to mold and decay.
• Ignoring Safety Precautions: Ignoring safety precautions can lead to serious injuries.

Case Study: Successful Firewood Preparation

I once consulted with a small family-owned farm that wanted to start selling firewood as a side business. They had a large wooded area on their property, but they lacked the equipment and expertise to process the wood efficiently.

I helped them develop a firewood preparation plan that included:

• Purchasing a used hydraulic log splitter: This significantly increased their splitting capacity.
• Building a firewood drying shed: This provided a well-ventilated space for seasoning the wood.
• Implementing safe felling and de-limbing procedures: This ensured the safety of the workers.
• Marketing their firewood to local customers: This helped them build a customer base.

Within a year, the farm was selling a significant amount of firewood and generating a substantial income. Their success was due to careful planning, efficient equipment, and a commitment to safety.
