Pro Tip #1: Mastering Chain Selection and Sharpening

The chain is the heart of any chainsaw. Choosing the right chain and keeping it properly sharpened are critical for maximizing cutting efficiency and extending the life of your Stihl MS460.

Chain Types

• Full Chisel: Aggressive cutting, best for clean wood.
• Semi-Chisel: Versatile, good for both clean and slightly dirty wood.
• Low-Kickback: Safer, but slower cutting.

I generally prefer a full chisel chain for its speed and efficiency when working with clean timber. However, if I’m cutting near the ground or dealing with dirty wood, I switch to a semi-chisel chain to avoid dulling the chain too quickly.

Chain Pitch and Gauge

The Stihl MS460 typically uses a .375″ (3/8″) pitch chain with a .050″ gauge. It is important to verify what your chainsaw uses before purchasing. Using the wrong pitch or gauge can damage your chainsaw and reduce cutting performance.

Chain Sharpening

A dull chain is not only inefficient but also dangerous. It forces you to apply more pressure, increasing the risk of kickback and fatigue. I sharpen my chains regularly, usually after every two or three tanks of fuel.

Tools You’ll Need:

• Chainsaw File: A round file matched to the chain’s pitch.
• File Guide: Helps maintain the correct filing angle and depth.
• Depth Gauge Tool: For adjusting the depth gauges (rakers).
• Vise: To securely hold the chain.

Sharpening Procedure:

1. Secure the chain in a vise.
2. Use the file guide to maintain the correct filing angle (typically 30 degrees).
3. File each cutter tooth from the inside out, using smooth, consistent strokes.
4. Ensure all cutter teeth are filed to the same length.
5. Use the depth gauge tool to check and adjust the depth gauges (rakers) as needed. Lowering the rakers increases the chain’s bite.
6. Rotate the chain and repeat the process for the remaining cutter teeth.

Common Mistakes to Avoid:

• Filing at the wrong angle.
• Rounding off the cutter teeth.
• Failing to maintain consistent file strokes.
• Neglecting the depth gauges.

Takeaway: Mastering chain selection and sharpening is essential for maximizing the Stihl MS460’s cutting performance. A sharp chain cuts faster, safer, and with less effort. A dull chain can turn your powerful saw into an underperforming hazard.

The Stihl MS460 requires a 50:1 fuel-to-oil ratio. This means mixing 50 parts of gasoline with 1 part of two-stroke oil. I always use high-quality, synthetic two-stroke oil specifically designed for air-cooled engines.

Why 50:1?

This ratio provides the optimal balance of lubrication and combustion. Too much oil can cause excessive carbon buildup, while too little oil can lead to engine damage.

Mixing Procedure:

1. Use a clean fuel container.
2. Pour the correct amount of two-stroke oil into the container.
3. Add the gasoline.
4. Secure the cap and shake the container thoroughly to mix the fuel and oil.

Fuel Recommendations:

• Use gasoline with an octane rating of 89 or higher.
• Avoid using gasoline that contains ethanol, as it can damage the engine. If you must use ethanol-blended gasoline, use a fuel stabilizer.
• Store fuel in a cool, dry place.
• Discard fuel that is more than 30 days old.

Bar Oil

Bar oil lubricates the chain and bar, reducing friction and wear. I use a high-quality bar oil specifically designed for chainsaws.

Bar Oil Recommendations:

• Use a bar oil with a viscosity appropriate for the ambient temperature. Thicker oils are better for warmer weather, while thinner oils are better for colder weather.
• Avoid using waste oil or motor oil as bar oil, as they can damage the chain and bar.
• Check the bar oil level frequently and refill as needed.

Oiling System Maintenance:

The Stihl MS460 has an adjustable oiler. I adjust the oiler to ensure that the chain is adequately lubricated without excessive oil consumption.

Common Mistakes to Avoid:

• Using the wrong fuel-to-oil ratio.

Felling Cuts

The standard felling cuts consist of the notch cut and the back cut.

Notch Cut:

The notch cut determines the direction of the fall. It should be cut on the side of the tree that you want it to fall towards.

• Open Face Notch: A notch with a wide opening.
• Conventional Notch: A notch with a 45-degree angle.

I generally prefer the conventional notch for its simplicity and effectiveness.

Back Cut:

The back cut is made on the opposite side of the tree from the notch cut. It should be made slightly higher than the bottom of the notch cut, leaving a hinge of wood to control the fall.

Hinge Wood:

The hinge wood is the portion of wood left uncut between the notch and back cut. It acts as a hinge, guiding the tree’s fall. The width and thickness of the hinge wood are critical for controlling the fall.

Felling Wedges:

Felling wedges are used to help push the tree over in the desired direction. They are inserted into the back cut after it has been partially completed.

Felling Procedure:

1. Clear the area around the tree.
2. Establish your escape routes.
3. Make the notch cut.
4. Make the back cut, leaving the hinge wood intact.
5. Insert felling wedges into the back cut.
6. Hammer the wedges to push the tree over.
7. Retreat along your escape route as the tree falls.

Common Mistakes to Avoid:

• Failing to assess the tree and its surroundings.
• Making the notch cut too shallow or too deep.
