2. Weight and Handling

Weight is a crucial factor, especially when you’re working for extended periods. A heavier saw can lead to fatigue and decreased precision.

• MS 250: Weighs approximately 4.6 kg (10.1 lbs) without the bar and chain.
• MS 271: Weighs around 5.6 kg (12.3 lbs) without the bar and chain.

My Perspective: The MS 250’s lighter weight makes it more maneuverable and less tiring to use for extended periods. I’ve found it particularly useful for tasks like limbing, where you’re constantly moving the saw around. The MS 271, while heavier, offers better stability when cutting larger logs. The added weight helps to dampen vibrations and provides a more solid feel.

Practical Example: When I’m clearing brush and small trees, the MS 250 is my go-to. I can work for hours without feeling overly fatigued. However, when I’m felling larger trees, the MS 271’s stability is preferable, especially in challenging conditions.

Actionable Advice: Consider the type of work you’ll be doing most often. If you prioritize maneuverability and ease of use for smaller tasks, the MS 250 is a better choice. If you need a more robust saw for larger logs, the MS 271 is worth the extra weight.

3. Bar Length and Cutting Capacity

The bar length determines the maximum diameter of wood you can cut.

• MS 250: Typically comes with a bar length ranging from 16 to 18 inches.
• MS 271: Usually equipped with a bar length of 16 to 20 inches.

Real-World Scenario: I’ve found that a 16-inch bar is sufficient for most firewood processing and small tree felling. However, when dealing with larger trees, a 20-inch bar on the MS 271 provides the extra reach needed to make clean cuts.

Expert Tip: While you can technically cut a tree with a diameter larger than the bar length by cutting from both sides, it’s generally safer and more efficient to use a saw with a bar length that matches the typical size of the trees you’ll be cutting.

Recommendation: If you regularly encounter trees with diameters approaching 20 inches, the MS 271 with a longer bar is the better option. For smaller trees and firewood, the MS 250 with a 16-inch bar is usually adequate.

Deep Dive: Understanding Wood Types and Cutting Techniques

Choosing the right chainsaw is only the first step. Understanding wood types and employing proper cutting techniques are equally important for safety and efficiency.

Identifying Wood Types

Different wood types have varying densities and hardness, which affect cutting difficulty and chainsaw performance.

• Softwoods: Pine, fir, spruce. Easier to cut, requiring less power.
• Hardwoods: Oak, maple, hickory. Denser and more challenging to cut, demanding more power and a sharper chain.

My Experience: I’ve learned that using a dull chain on hardwood can be incredibly frustrating and even dangerous. The saw can bind, kick back, or overheat. Always ensure your chain is sharp and properly tensioned before cutting.

Practical Application: When cutting softwoods, I often use a slightly higher chain speed to maximize efficiency. For hardwoods, I reduce the chain speed and apply more pressure to allow the chain to bite into the wood.

Essential Cutting Techniques

Mastering basic cutting techniques is crucial for safety and efficiency.

• Felling: Safely bringing down a tree. Requires careful planning, including assessing the tree’s lean, wind direction, and potential hazards.
• Bucking: Cutting a felled tree into smaller logs. Use proper support and cutting techniques to prevent the saw from binding.
• Limbing: Removing branches from a felled tree. Exercise caution to avoid kickback and ensure a stable footing.

Safety First: Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.

Expert Advice: When felling a tree, always cut a notch on the side of the tree in the direction you want it to fall. This helps to control the direction of the fall and prevent the tree from falling unexpectedly.

Optimizing Your Chainsaw for Firewood Preparation

Firewood preparation is a common application for both the MS 250 and MS 271. Here’s how to optimize your chainsaw for this task:

Choosing the Right Bar and Chain

The bar and chain are critical components for efficient firewood processing.
