From my own experience, the MS 311 shines in its balance of power and weight. I’ve used it for everything from felling medium-sized trees to bucking firewood, and it consistently delivers reliable performance. The anti-vibration system is a game-changer, especially during long days in the woods.

5 Pro Tips for Efficient Woodcutting with the MS 311

Now, let’s get to the meat of the matter: how to maximize your woodcutting efficiency with the MS 311. These tips are based on years of personal experience and observations in the field.

Tip 1: Master the Art of Chain Sharpening

A sharp chain is the single most important factor in efficient woodcutting. A dull chain not only slows you down but also puts unnecessary strain on the saw and increases the risk of kickback.

Why Sharpening Matters

  • Increased Cutting Speed: A sharp chain bites into the wood with minimal effort, allowing you to cut faster and more efficiently.
  • Reduced Strain on the Saw: A dull chain forces the saw to work harder, leading to increased fuel consumption and potential engine damage.
  • Improved Safety: A sharp chain is less likely to kick back, reducing the risk of accidents.

Sharpening Techniques

  • Using a File: This is the most common method and allows for precise sharpening. Use a round file of the correct size (typically 5/32″ for the MS 311) and a file guide to maintain the correct angle and depth.
    • Angle: The top plate angle should be around 30 degrees, and the side plate angle around 60 degrees.
    • Depth: File each tooth evenly, removing only a small amount of material with each stroke.
  • Using a Grinder: Electric grinders can sharpen chains quickly and efficiently, but they require more skill and caution to avoid damaging the teeth.
    • Coolant: Always use coolant when grinding to prevent overheating the teeth, which can weaken them.
    • Consistent Pressure: Apply consistent pressure and avoid grinding for too long in one spot.
  • On-the-Go Sharpening: I always carry a small file with me in the field for quick touch-ups. A few strokes on each tooth can make a big difference in performance.

Data-Backed Insights

  • Sharpening Frequency: A study by the Forest Products Laboratory found that sharpening a chainsaw chain every 2-3 hours of use can increase cutting efficiency by up to 20%.
  • Sharpening Angle: Maintaining the correct sharpening angle is crucial. A deviation of just 5 degrees can reduce cutting speed by 10%.

Personal Story

I remember one particularly frustrating day when I was trying to buck a pile of oak logs with a dull chain. I was sweating, the saw was bogging down, and progress was painfully slow. Finally, I took a break to sharpen the chain, and the difference was night and day. The saw sliced through the wood with ease, and I finished the job in half the time. That day, I learned the true value of a sharp chain.

Tip 2: Optimize Bar and Chain Selection

The right bar and chain combination can significantly impact your cutting efficiency. The MS 311 is versatile, but choosing the wrong setup can hinder its performance.

Bar Length

  • Shorter Bars (16″): Ideal for limbing and cutting smaller pieces of wood. They offer better maneuverability and control.
  • Medium Bars (18″): A good all-around choice for general firewood cutting and felling small to medium-sized trees.
  • Longer Bars (20″): Best for felling larger trees and cutting thick logs. However, they require more power and skill to handle safely.

Chain Type

  • Full Chisel: These chains have square-cornered teeth that cut aggressively and quickly. They are best suited for clean wood and require more frequent sharpening.
  • Semi-Chisel: These chains have rounded-corner teeth that are more durable and forgiving in dirty or frozen wood. They are a good choice for general use.
  • Low-Kickback: These chains have guard links that reduce the risk of kickback. They are a good choice for beginners or those working in tight spaces.

Matching Bar and Chain

  • Power Match: Ensure the bar length is appropriate for the saw’s engine power. A bar that is too long will bog down the saw and reduce cutting speed.
  • Chain Pitch and Gauge: The chain must match the bar’s pitch and gauge. The pitch is the distance between the chain’s drive links, and the gauge is the thickness of the drive links.

Data-Backed Insights

  • Bar Length and Efficiency: A study by Oregon found that using the correct bar length for the size of the wood being cut can increase cutting efficiency by up to 15%.
  • Chain Type and Durability: Semi-chisel chains last approximately 25% longer than full chisel chains in dirty wood conditions.

Case Study

I once worked on a project where we were felling large oak trees. We initially used 18-inch bars with full chisel chains. While the cutting was fast, we were constantly sharpening the chains due to the dirty bark. We switched to 20-inch bars with semi-chisel chains, and the cutting speed decreased slightly, but the chains lasted much longer, resulting in an overall increase in efficiency.

Tip 3: Master Cutting Techniques for Different Wood Types

Different wood types require different cutting techniques. Understanding these nuances can save you time, energy, and frustration.

Hardwoods vs. Softwoods

  • Hardwoods (Oak, Maple, Hickory): These woods are dense and require more power to cut. Use a sharp chain, maintain a steady pressure, and avoid forcing the saw.
  • Softwoods (Pine, Fir, Spruce): These woods are less dense and easier to cut. Use a faster chain speed and a lighter touch.

Cutting Techniques

  • Felling: Use the proper felling cuts to control the direction of the fall. This includes the undercut, back cut, and hinge.
  • Bucking: Cut logs into manageable lengths for firewood or other uses. Use proper support techniques to prevent the log from pinching the saw.
  • Limbing: Remove branches from felled trees. Work from the base of the tree towards the top, and be mindful of spring poles and kickback.

Data-Backed Insights

  • Wood Density and Cutting Speed: A study by the USDA Forest Service found that cutting speed decreases by approximately 10% for every 10% increase in wood density.
  • Proper Felling Techniques: Using proper felling techniques can reduce the risk of accidents by up to 50%.

Real Example

I was once helping a friend cut firewood from a fallen maple tree. He was struggling to buck the logs, and the saw kept getting pinched. I showed him how to use a support log to prevent the log from pinching, and he was able to cut the rest of the logs quickly and easily.
