Key Concepts in Wood Processing

Before diving into the specifics of using a Dolmar Sachs chainsaw, let’s establish a foundation of key concepts:

Green Wood vs. Seasoned Wood: Green wood is freshly cut timber with a high moisture content (often over 50%). It’s heavy, difficult to split, and burns poorly. Seasoned wood, on the other hand, has been allowed to dry, reducing its moisture content to 20% or less. It’s lighter, easier to split, and burns hotter and cleaner. The goal in firewood preparation is to transform green wood into seasoned wood.
Moisture Content: The amount of water present in wood, expressed as a percentage of the wood’s dry weight. This is the single most important factor determining firewood quality.
BTU (British Thermal Unit): A measure of heat energy. Different wood species have different BTU ratings, indicating how much heat they produce when burned. Hardwoods like oak and maple generally have higher BTU ratings than softwoods like pine and fir.
Cord: A standard unit of measurement for firewood. A full cord is 4 feet high, 4 feet wide, and 8 feet long, totaling 128 cubic feet.
Kerf: The width of the cut made by the chainsaw. A wider kerf requires more power and produces more sawdust.
Kickback: A sudden, uncontrolled upward or backward movement of the chainsaw bar, which can be extremely dangerous. Understanding and preventing kickback is crucial for chainsaw safety.
Felling: The process of cutting down a tree.
De-limbing: The process of removing branches from a felled tree.
Bucking: The process of cutting a felled tree into shorter lengths.

Tool Selection: Chainsaw vs. Axe vs. Other Options

While the Dolmar Sachs chainsaw is the star of this guide, it’s important to recognize that it’s not always the best tool for every job. Let’s compare it to other common wood processing tools:

Chainsaw: Ideal for felling trees, de-limbing, bucking, and cutting large quantities of firewood. Offers speed and power but requires maintenance and safety precautions.
Axe: Best for splitting logs, especially smaller rounds. Requires physical strength and proper technique. Can also be used for felling small trees in a pinch.
Splitting Maul: A heavier version of an axe, designed specifically for splitting large, stubborn logs.
Wedges: Used in conjunction with a sledgehammer to split logs that are too difficult to split with an axe or maul.
Hydraulic Log Splitter: A powered machine that uses hydraulic pressure to split logs. Offers speed and efficiency for large-scale firewood production.
Bow Saw: A lightweight, portable saw for cutting small branches and firewood. Requires manual effort but is quiet and environmentally friendly.

Unique Insight: For small-scale firewood preparation, a combination of a Dolmar Sachs chainsaw for bucking and an axe or splitting maul for splitting is often the most cost-effective and efficient approach. For larger-scale operations, a hydraulic log splitter can significantly reduce labor and increase production.

Choosing the Right Dolmar Sachs Chainsaw

Dolmar Sachs (now often branded as just Dolmar, or under Makita since their acquisition) produced a range of chainsaws, each designed for different applications. When selecting a Dolmar Sachs chainsaw, consider the following factors:

Engine Size: Measured in cubic centimeters (cc), engine size determines the power of the chainsaw. Larger engines are better suited for felling large trees and cutting dense hardwoods. Smaller engines are adequate for lighter tasks such as de-limbing and cutting small firewood.
Bar Length: The length of the guide bar determines the maximum diameter of wood that can be cut. A longer bar allows you to fell larger trees but also makes the chainsaw heavier and more difficult to maneuver.
Weight: Chainsaw weight is a crucial factor, especially for prolonged use. Choose a chainsaw that is comfortable to handle and doesn’t cause excessive fatigue.
Features: Look for features such as anti-vibration systems, chain brakes, and automatic oilers, which improve safety and ease of use.
Condition (for used models): If buying a used Dolmar Sachs chainsaw, carefully inspect it for signs of wear and tear, such as cracks in the housing, loose parts, and excessive engine noise. Ask to see it running and test its cutting performance.

Personalized Story: I remember buying a used Dolmar Sachs 115i from a local farmer. It was a workhorse, but it needed some TLC. I spent a weekend cleaning it, replacing the spark plug, and sharpening the chain. The satisfaction of bringing that old machine back to life was immense.

Safety First: Essential Chainsaw Safety Practices

Chainsaw operation is inherently dangerous. Accidents can result in serious injury or even death. Always follow these safety practices:

Wear appropriate personal protective equipment (PPE): This includes a chainsaw helmet with face shield and ear protection, cut-resistant chaps or pants, gloves, and sturdy boots.
Read and understand the chainsaw’s operating manual: Familiarize yourself with the chainsaw’s controls, safety features, and maintenance requirements.
Inspect the chainsaw before each use: Check the chain tension, oil level, and all other components for damage or wear.
Start the chainsaw on the ground or on a firm, stable surface: Never drop-start a chainsaw.
Maintain a firm grip on the chainsaw with both hands: Keep your thumbs wrapped around the handles.
Keep your feet firmly planted and maintain a stable stance: Avoid overreaching or cutting above shoulder height.
Be aware of your surroundings: Look for obstacles such as rocks, branches, and power lines.
Never cut alone: Always have someone nearby in case of an emergency.
Avoid kickback: Understand the causes of kickback and use techniques to prevent it.
Take frequent breaks: Chainsaw operation can be physically and mentally demanding.

Data Point: According to the Consumer Product Safety Commission (CPSC), chainsaws cause tens of thousands of injuries each year in the United States alone. Wearing appropriate PPE and following safety guidelines can significantly reduce the risk of injury.

Step-by-Step Guide to Felling a Tree with a Dolmar Sachs Chainsaw

Felling a tree is a complex and potentially dangerous task. This guide provides a general overview of the process, but it’s essential to seek professional training and guidance before attempting to fell a tree on your own.

Assess the Tree and Surroundings:
- Lean: Determine the natural lean of the tree. This will influence the direction it will fall.
- Obstacles: Identify any obstacles that could interfere with the tree’s fall, such as power lines, buildings, or other trees.
- Wind: Consider the wind direction. A strong wind can significantly alter the tree’s trajectory.
- Escape Route: Plan a clear escape route at a 45-degree angle away from the direction of the fall.
Clear the Area: Remove any brush, rocks, or other obstacles from around the base of the tree and along your escape route.
Make the Notch Cut:
- Directional Cut: This cut determines the direction the tree will fall. It consists of two cuts:
  - The Top Cut: Made at a 45-degree angle, sloping downwards to meet the horizontal cut.
  - The Horizontal Cut: Made horizontally to meet the top cut, creating a wedge-shaped notch. The notch should be about one-fifth to one-third of the tree’s diameter.
Make the Back Cut:
- Position: Made on the opposite side of the tree from the notch cut, slightly above the horizontal cut.
- Technique: Cut horizontally towards the notch, leaving a hinge of uncut wood. The hinge controls the direction of the fall and prevents the tree from kicking back. The hinge should be about one-tenth of the tree’s diameter.
Wedge (If Necessary): If the tree doesn’t start to fall on its own, insert wedges into the back cut and drive them in with a sledgehammer to encourage the tree to fall in the desired direction.
Retreat: As the tree begins to fall, shout a warning (“Timber!”) and retreat quickly along your planned escape route.
Observe: Watch the tree as it falls to ensure it lands safely.

Troubleshooting:

Tree Leans Backwards: If the tree leans backwards and pinches the chainsaw, use wedges to relieve the pressure and allow you to remove the saw.
Tree Doesn’t Fall: If the tree doesn’t fall after making the back cut, check the hinge. It may be too thick. Insert wedges and drive them in further to encourage the tree to fall.

De-limbing and Bucking with a Dolmar Sachs Chainsaw

Once the tree is felled, the next steps are de-limbing (removing the branches) and bucking (cutting the trunk into shorter lengths).

De-limbing

Safety First: Wear appropriate PPE and be aware of your surroundings.
Start from the Base: Begin de-limbing from the base of the tree and work your way towards the top.
Cut on the Opposite Side: Position yourself on the opposite side of the branch from where you are cutting. This will prevent the branch from pinching the chainsaw.
Use Proper Technique: Use a smooth, controlled cutting motion. Avoid forcing the chainsaw.
Be Aware of Spring Poles: Be especially careful when cutting branches that are under tension (spring poles). These branches can snap back unexpectedly and cause injury.
Clear the Area: As you de-limb, clear the branches away from the trunk to make bucking easier.

Bucking

Determine Lengths: Decide on the desired length of the firewood. A common length is 16 inches, but you can adjust this to suit your stove or fireplace.
Measure and Mark: Use a measuring tape and crayon or marking paint to mark the trunk at the desired lengths.
Support the Trunk: Ensure the trunk is properly supported to prevent it from pinching the chainsaw. You can use logs, rocks, or specialized bucking stands.
Use Proper Technique: Use a smooth, controlled cutting motion. Avoid forcing the chainsaw.
Cut All the Way Through: Cut completely through the trunk at each mark.
Stack the Firewood: As you buck the trunk, stack the firewood in a neat and organized manner.

Unique Insight: When bucking firewood, consider the size of your stove or fireplace. Cutting the wood slightly shorter than the maximum length it can accommodate will make it easier to load and burn.

Firewood Seasoning: The Key to Efficient Burning

Seasoning firewood is the process of drying it to reduce its moisture content. Seasoned firewood burns hotter, cleaner, and more efficiently than green firewood.

Split the Wood: Splitting firewood exposes more surface area to the air, accelerating the drying process.
Stack the Wood Properly: Stack the firewood in a single row, with the bark facing up. This will help to shed rain and prevent the wood from rotting.
Elevate the Wood: Elevate the wood off the ground using pallets, logs, or rocks. This will improve air circulation and prevent moisture from wicking up from the ground.
Choose a Sunny and Windy Location: A sunny and windy location will promote faster drying.
Cover the Top of the Stack: Cover the top of the stack with a tarp or sheet of metal to protect it from rain and snow. Leave the sides of the stack open to allow for air circulation.
Allow Adequate Drying Time: The amount of time required to season firewood depends on the species of wood, the climate, and the stacking method. Generally, hardwoods require at least six months to a year to season properly, while softwoods may dry more quickly.

Data Point: Studies have shown that properly seasoned firewood can produce up to 50% more heat than green firewood.

Case Study: A local firewood producer in my area implemented a new seasoning strategy that involved stacking the wood on pallets, covering the top of the stack with a tarp, and using a fan to circulate air. This resulted in a 30% reduction in drying time and a significant improvement in firewood quality.
