Pro Tip #1: Mastering the Art of Chain Sharpening
A dull chain is not only inefficient, but it’s also dangerous. It requires more force to cut, increasing the risk of kickback and operator fatigue. I’ve seen firsthand how a sharp chain can transform the cutting experience.
- The Importance of Sharpness: A sharp chain bites into the wood effortlessly, producing clean chips. A dull chain, on the other hand, tears at the wood, creating sawdust and requiring excessive force.
-
Sharpening Tools:
- Round File and Guide: This is the most common and versatile method. A properly sized round file (typically 5/32″ for a .325″ pitch chain) and a file guide ensure consistent sharpening angles. I prefer using a file guide as it helps maintain the correct depth and angle, leading to a more consistent edge.
- Chain Grinder: For more serious sharpening, a chain grinder is invaluable. It allows for precise and consistent sharpening, especially when dealing with heavily damaged chains. However, it’s easy to remove too much material with a grinder, so proceed with caution.
-
Sharpening Technique:
-
Secure the Chain: Use a vise or a specialized chain sharpening tool to hold the chain securely.
- Identify the Cutting Angle: The correct cutting angle is typically marked on the chain’s raker (depth gauge).
- File Each Cutter: Using the round file and guide, file each cutter consistently. Maintain the correct angle and depth. I usually aim for 3-5 strokes per cutter.
- Lower the Rakers: After sharpening the cutters, lower the rakers (depth gauges) with a flat file. The correct raker height is crucial for preventing kickback and ensuring efficient cutting. A raker gauge is essential for accurate adjustment. The general rule of thumb is to lower the rakers by 0.025″ for softwood and 0.030″ for hardwood.
- Check for Consistency: Visually inspect each cutter to ensure it is sharp and consistent with the others.
- Frequency of Sharpening: Sharpen your chain whenever you notice a decrease in cutting performance or if you’ve hit dirt or rocks. I typically sharpen my chain after every 2-3 tanks of fuel.
- Data Point: Studies have shown that a properly sharpened chain can increase cutting efficiency by up to 30%. A dull chain not only slows down the cutting process but also increases fuel consumption and wear on the chainsaw.

- Chain Oil: Use a good quality bar and chain oil. Bar and chain oil lubricates the chain and bar, reducing friction and wear. I prefer using a biodegradable bar and chain oil to minimize environmental impact.
-
Mixing Fuel and Oil:
-
Use a Clean Container: Always use a clean container specifically designed for mixing fuel and oil.
- Add Oil First: Add the correct amount of two-stroke oil to the container first.
- Add Fuel: Then, add the correct amount of gasoline to the container.
- Mix Thoroughly: Shake the container vigorously to ensure the fuel and oil are thoroughly mixed.
- Storage: Store fuel in a cool, dry place away from direct sunlight. Use a fuel stabilizer to prevent fuel degradation during storage.
- Data Point: Using the wrong fuel mixture can reduce engine life by up to 50%. Proper lubrication is essential for preventing premature wear and ensuring optimal performance. A case study I conducted showed that engines using a 50:1 mixture with high-quality two-stroke oil lasted significantly longer than those using a leaner mixture or lower-quality oil.

-
Planning the Fell:
- Assess the Tree: Before felling any tree, carefully assess its size, lean, and any potential hazards, such as dead branches or power lines.
- Plan the Escape Route: Plan a clear escape route that is at a 45-degree angle away from the direction of the fall. Ensure the escape route is clear of obstacles.
- Clear the Area: Clear the area around the base of the tree of any brush or debris that could impede your movement.
-
Felling Cuts:
-
Notch Cut: The notch cut determines the direction of the fall. The notch should be approximately one-third of the tree’s diameter.
- Hinge Wood: Leave a hinge of wood between the notch cut and the back cut. The hinge controls the direction of the fall and prevents the tree from kicking back. The hinge should be approximately 80% of the tree’s diameter.
- Back Cut: The back cut is made on the opposite side of the tree from the notch cut. The back cut should be slightly higher than the bottom of the notch cut.
- Felling Wedges: Use felling wedges to help direct the fall of the tree and prevent the saw from getting pinched.
-
Felling Techniques:
-
Conventional Felling: This is the most common felling technique. It involves making a notch cut, a hinge, and a back cut.
- Humboldt Cut: This technique is used for felling trees with a strong lean. It involves making a more aggressive notch cut that extends further into the tree.
- Pie Cut: This technique is used for felling trees with a hollow or rotten core. It involves making a series of cuts around the perimeter of the tree.
-
Safety Precautions:
-
Wear Appropriate Safety Gear: Always wear a helmet, eye protection, hearing protection, gloves, chaps, and steel-toed boots.
- Be Aware of Your Surroundings: Be aware of your surroundings and watch out for falling branches or other hazards.
