Stihl What Does MS Stand For? (Chainsaw Model Secrets Revealed)

Let’s dive into the world of chainsaws and uncover the mystery behind Stihl’s “MS” designation. As someone who’s spent years felling trees, processing timber, and preparing firewood, I’ve come to appreciate the intricacies of chainsaw technology. Understanding the meaning behind model numbers like “MS” is more than just trivia; it’s about grasping the engineering philosophy and intended application of a specific saw. It’s also important to make these choices with our furry friends in mind, opting for eco-friendly bar and chain oil and ensuring they are safely away from the worksite.

Stihl Chainsaw Model Decoding: Unveiling the “MS” Secret and Beyond

The question “Stihl What Does MS Stand For?” is one I’ve heard countless times. While it may seem like a simple query, the answer opens the door to a deeper understanding of Stihl’s chainsaw lineup and how to choose the right tool for the job. The “MS” in Stihl chainsaw model numbers stands for “Motorsäge,” which is German for “motor saw” or “chainsaw.” It’s a straightforward designation, but it’s the starting point for deciphering the rest of the model number.

Understanding Stihl’s Numbering System: A Step-by-Step Guide

I remember when I first started, I was completely overwhelmed by the array of chainsaw models. Learning the numbering system was crucial. Here’s a breakdown:

1. The “MS” Prefix: As mentioned, this simply signifies that it’s a Stihl chainsaw.

2. The Numerical Designation: The numbers following the “MS” are more informative. Generally, higher numbers indicate larger, more powerful saws designed for heavier-duty tasks. For example, an MS 170 is a smaller, lighter saw suitable for occasional use around the home, while an MS 462 is a professional-grade saw designed for felling large trees.

3. Variations and Suffixes: Stihl often uses suffixes to denote specific features or improvements. Here are some common examples:

   • “C”: Comfort features, such as toolless chain tensioning (“C-B”) or ErgoStart (“C-E”). Toolless chain tensioning is a fantastic feature for quick adjustments in the field. I’ve found it saves valuable time when bucking firewood.
   • “E”: Electric start. While less common on professional saws, electric start can be a welcome feature on smaller models.
   • “Q”: QuickStop chain braking system. This is a crucial safety feature that I always recommend.
   • “W”: Wrap handle, which provides a secure grip for felling at various angles. I’ve used wrap handles extensively when working in dense forests.
   • “Z”: Heated handle, designed for cold weather operation. This is essential for loggers working in northern climates.

   For instance, an MS 271 Farm Boss C-BE indicates a model with comfort features, ErgoStart, and toolless chain tensioning.

Key Concepts in Chainsaw Selection

Before diving deeper, let’s define some key terms that are essential for understanding chainsaw operation and maintenance:

• Bar Length: The length of the guide bar, which determines the maximum diameter of the wood you can cut. I typically use a 20-inch bar for most of my firewood processing.
• Chain Pitch: The distance between three consecutive rivets on the chain, divided by two. Common pitches are 3/8″ and .325″.
• Chain Gauge: The thickness of the drive links on the chain, which must match the groove width of the guide bar.
• Engine Displacement: The volume of the engine’s cylinders, measured in cubic centimeters (cc). Higher displacement generally means more power.
• Power-to-Weight Ratio: A crucial factor in chainsaw selection. A saw with a good power-to-weight ratio will be more efficient and less fatiguing to use.
• Green Wood vs. Seasoned Wood: Green wood is freshly cut and contains a high moisture content, making it heavier and more difficult to burn. Seasoned wood has been dried, reducing its moisture content and making it easier to ignite and burn efficiently. I always prefer to season my firewood for at least six months before burning.
• Bucking: Cutting a felled tree into shorter lengths.
• Felling: The process of cutting down a tree.
• Limbing: Removing branches from a felled tree.

Detailed Guide: Felling a Tree Safely and Efficiently

Felling a tree is a dangerous task that should only be attempted by experienced individuals. However, understanding the process is essential for anyone involved in wood processing. Here’s a step-by-step guide:

1. Planning and Preparation:

   • Assess the Tree: Determine the tree’s lean, the presence of dead branches, and any obstacles in the surrounding area. Consider wind direction and its potential impact on the felling direction.
   • Clear the Work Area: Remove any brush, rocks, or other obstacles that could pose a tripping hazard. Create a clear escape path at a 45-degree angle away from the intended felling direction.
   • Personal Protective Equipment (PPE): Always wear a helmet, eye protection, hearing protection, chainsaw chaps, and work boots. I never start working without my full PPE.
   • Tools: Ensure your chainsaw is in good working condition, with a sharp chain and adequate fuel and oil. You’ll also need a felling axe or wedges to assist in directing the tree’s fall.

2. Making the Notch (Undercut):

   • Purpose: The notch determines the direction of the fall. It should be cut on the side of the tree facing the intended felling direction.
   • Procedure: Make a horizontal cut into the tree, approximately one-third of the tree’s diameter. Then, make a sloping cut that meets the horizontal cut at a 45-degree angle. Remove the wedge of wood. The notch should be clean and precise.
   • Measurements: The notch should be wide enough to allow the tree to fall freely in the intended direction.

3. Making the Back Cut:

   • Purpose: The back cut severs the remaining wood fibers and allows the tree to fall.
   • Procedure: Make the back cut on the opposite side of the tree from the notch, slightly above the horizontal cut of the notch. Leave a hinge of wood (approximately 10% of the tree’s diameter) to control the fall.
   • Safety: Never cut completely through the tree. The hinge is crucial for controlling the fall.
   • Using Wedges: If the tree starts to lean in the wrong direction or if the saw becomes pinched, insert felling wedges into the back cut to help direct the fall. I’ve used wedges countless times to prevent trees from barber-chairing (splitting upwards).

4. Felling the Tree:

   • Warning: Shout a warning (“Timber!”) to alert anyone in the area.
   • Retreat: As the tree begins to fall, retreat quickly along your pre-planned escape path. Watch out for falling branches.

5. Case Study:

   I remember once felling a large oak tree that had a significant lean in the wrong direction. I used multiple wedges and a come-along to pull the tree in the desired direction. It was a challenging situation, but careful planning and execution ensured a safe and successful felling.

Debarking Logs: Methods and Tools

Debarking logs is an important step in many wood processing applications, including lumber production, woodworking, and firewood preparation. Removing the bark prevents insect infestation, reduces rot, and speeds up the drying process. Here are several methods for debarking logs:

• Manual Debarking: This is the most common method for small-scale operations. Tools include:

  • Drawknife: A two-handled blade used to shave off the bark. This is my preferred method for small logs.
  • Spud: A specialized tool with a curved blade designed for peeling bark.
  • Axe: Can be used to chop away the bark, but requires more skill to avoid damaging the wood.

• Mechanical Debarking: For larger-scale operations, mechanical debarkers are used. These machines use various methods, such as rotating drums or knives, to remove the bark.

• Hydraulic Debarking: This method uses high-pressure water jets to blast the bark off the log. It’s effective but requires specialized equipment.

Splitting Firewood: Techniques and Tools

Splitting firewood is a crucial step in preparing it for burning. Properly split firewood dries faster and burns more efficiently. Here are several techniques and tools for splitting firewood:

• Manual Splitting:

  • Axe: The traditional tool for splitting firewood. Choose an axe with a head weight of 6-8 pounds and a handle length that suits your height. I prefer a maul for splitting larger rounds.
  • Maul: A heavier version of an axe, designed for splitting larger, tougher rounds. A maul typically weighs 6-10 pounds.
  • Wedges: Used to split particularly tough or knotty rounds. Drive the wedge into the wood with a sledgehammer.

• Hydraulic Log Splitters: These machines use hydraulic power to split logs. They are available in various sizes and splitting forces (measured in tons).

  • Electric Log Splitters: Suitable for smaller-scale firewood production. Typically have a splitting force of 5-10 tons.
  • Gas-Powered Log Splitters: More powerful and suitable for larger-scale operations. Can have a splitting force of 20-30 tons or more. I use a 27-ton gas-powered splitter for my firewood business. It significantly increases my efficiency.

Step-by-Step Guide: Splitting Firewood with a Hydraulic Log Splitter

1. Safety First: Wear safety glasses, work gloves, and steel-toed boots. Ensure the log splitter is on a level surface and that the area is clear of obstructions.
2. Prepare the Log: Place the log on the log splitter’s beam, ensuring it is stable and centered under the splitting wedge.
3. Engage the Control Lever: Operate the control lever to advance the splitting wedge towards the log.
4. Split the Log: Continue advancing the wedge until the log splits.
5. Repeat: Repeat the process until the log is split into the desired size.
6. Stack the Firewood: Stack the split firewood in a well-ventilated area to allow it to dry.

Drying Firewood: Achieving Optimal Moisture Content

Drying firewood is essential for efficient burning. Green wood contains a high moisture content (often over 50%), which makes it difficult to ignite and burns inefficiently, producing excessive smoke and creosote. Seasoned firewood, on the other hand, has a moisture content of 20% or less.

• Air Drying: The most common method for drying firewood. Stack the wood in a single row, off the ground, and in a sunny, well-ventilated location. Allow the wood to dry for at least six months, or preferably a year. I always stack my firewood on pallets to keep it off the ground.
• Kiln Drying: A faster method for drying firewood, but requires specialized equipment. Kiln-dried firewood typically has a moisture content of 15-20%.

Measuring Moisture Content: Using a Moisture Meter

A moisture meter is an essential tool for determining the moisture content of firewood. Insert the probes of the meter into a freshly split piece of wood and read the moisture content percentage. Aim for a moisture content of 20% or less for optimal burning.

Case Study: Firewood Stacking Techniques for Optimal Drying

I experimented with different firewood stacking techniques to determine which method resulted in the fastest drying time. I found that stacking the wood in a single row, with ample space between the rows, allowed for the best air circulation and fastest drying. I also oriented the rows north-south to maximize sun exposure.

Safety Considerations in Wood Processing and Firewood Preparation

Safety is paramount in all aspects of wood processing and firewood preparation. Here are some essential safety considerations:

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including a helmet, eye protection, hearing protection, chainsaw chaps, work gloves, and steel-toed boots.
• Chainsaw Safety: Follow all manufacturer’s instructions and safety guidelines. Never operate a chainsaw when you are tired or under the influence of drugs or alcohol.
• Log Splitter Safety: Follow all manufacturer’s instructions and safety guidelines. Keep hands and feet clear of the splitting wedge.
