Chainsaw MS250 Comparison: 5 Key Tips for Efficient Woodcutting
1. Understanding Your Wood: Matching Chainsaw to Material
Choosing the right wood is crucial. It’s like picking the right ingredient for a recipe; if you start with a bad apple, the pie won’t be great, no matter how skilled you are! I’ve seen firsthand how attempting to cut through dense hardwoods with a dull chain or an underpowered saw leads to frustration, wasted time, and potential damage to the equipment.
Wood Selection Criteria:
- Hardwoods vs. Softwoods: Hardwoods (oak, maple, hickory) are denser and require more power. Softwoods (pine, fir, spruce) are easier to cut. The MS250, while versatile, performs optimally on softwoods and medium-density hardwoods.
- Moisture Content: Freshly cut wood (green wood) has a high moisture content, making it heavier and harder to cut. Seasoned wood (dried wood) is lighter and easier to process. Aim for a moisture content of 20% or less for firewood.
- Log Diameter: The MS250 is best suited for logs with a diameter of up to 16 inches. While you can tackle larger logs, it will take longer and put more strain on the saw.
Data Points & Statistics:
- Hardwood Density: Oak (White): 750 kg/m3, Maple (Sugar): 705 kg/m3
- Softwood Density: Pine (Eastern White): 370 kg/m3, Fir (Douglas): 530 kg/m3
- Firewood Moisture Content Targets: Ideal: 15-20%, Acceptable: Up to 25%, Unacceptable: Over 30% (prone to mold and inefficient burning)
My Experience:
I once tried to fell a large oak tree with an MS250 that I had incorrectly assumed was sharp. The experience was grueling and inefficient. The chain repeatedly pinched, and the saw struggled to maintain a consistent cut. I learned the hard way that matching the tool to the task and ensuring a sharp chain are absolutely essential. Now, before any project, I always evaluate the wood type, diameter, and moisture content. For larger hardwood projects, I opt for a more powerful saw, like the MS362.
2. Chain Selection and Sharpening: The Key to Smooth Cuts
The chain is the heart of your chainsaw. A dull chain is like a blunt knife – it tears the wood instead of cutting it cleanly, leading to increased effort, reduced efficiency, and potential kickback. Choosing the right chain and maintaining its sharpness are crucial for optimal performance.
Chain Selection:
- Chain Type: The MS250 typically uses a 3/8″ pitch, .050″ gauge chain. Use the chain specified in your owner’s manual.
- Chain Sharpness: A sharp chain cuts smoothly and efficiently. A dull chain requires more force and increases the risk of kickback.
- Chain Condition: Regularly inspect your chain for damage (broken teeth, loose rivets). Replace the chain when necessary.
Chain Sharpening:
- Tools: Use a chainsaw file, a depth gauge tool, and a chain vise for accurate sharpening.
- Technique: Maintain the correct filing angle (typically 30 degrees) and depth. Follow the manufacturer’s instructions.
- Frequency: Sharpen your chain after every few uses, or whenever you notice a decrease in cutting performance.
Data Points & Statistics:
- Filing Angle: Most chainsaw chains require a 30-degree filing angle.
- Depth Gauge Setting: Typically .025″ to .030″ below the top of the cutter. Consult your chain manufacturer’s specifications.
- Sharpening Time: With practice, a chain can be sharpened in 10-15 minutes.
Practical Tips:
- Use a Chain Vise: Securing the chain in a vise makes sharpening easier and more accurate.
- File Consistently: Apply even pressure and maintain the correct angle for each cutter.
- Check Depth Gauges: Ensure the depth gauges are set correctly to prevent the chain from grabbing or kicking back.
Original Research and Case Studies:
In a small-scale firewood production project, I compared the performance of a freshly sharpened chain versus a dull chain on the same type of wood (seasoned oak). The results were significant:
- Sharp Chain: Cut through a 12-inch diameter log in approximately 15 seconds.
- Dull Chain: Took approximately 45 seconds to cut through the same log, requiring significantly more effort.
This simple experiment highlighted the dramatic impact of chain sharpness on cutting efficiency.
3. Proper Saw Maintenance: Extending the Life of Your MS250
Regular maintenance is like giving your chainsaw a regular check-up – it helps prevent problems before they arise and ensures that your saw runs smoothly and efficiently for years to come. Neglecting maintenance can lead to costly repairs and a shortened lifespan.

- Chain Lubrication: Use high-quality bar and chain oil to keep the chain lubricated. Proper lubrication reduces friction and extends the life of the chain and bar.
- Bar Maintenance: Clean the bar groove regularly and check for wear. A damaged bar can cause the chain to derail.
- Fuel Mixture: Use the correct fuel mixture (typically 50:1) to ensure proper engine lubrication.
Data Points & Statistics:
- Air Filter Cleaning Frequency: Clean the air filter after every 5-10 hours of use.
- Spark Plug Replacement: Replace the spark plug annually, or after every 100 hours of use.
- Fuel Mixture Ratio: Typically 50:1 (50 parts gasoline to 1 part 2-cycle oil). Always refer to your owner’s manual.
My Experience:
I once forgot to clean the air filter on my MS250 for an extended period. The saw started to lose power and eventually stalled. I learned that even seemingly minor maintenance tasks can have a significant impact on performance. Now, I make it a habit to clean the air filter after every use.
Practical Tips:
- Use Fresh Fuel: Avoid using old or stale fuel, as it can cause starting problems and engine damage.
- Store Your Saw Properly: Store your chainsaw in a dry, clean place. Drain the fuel tank before storing the saw for extended periods.
