I’ve spent years in the woods, from felling trees in the dense forests of the Pacific Northwest to splitting firewood under the scorching sun of the Southwest. I’ve learned a thing or two about what works, what doesn’t, and how to get the most out of your equipment. In this guide, I’m diving deep into the Stihl MS 310 and MS 390 chainsaws, comparing their costs, performance, and features to help you decide which one is right for you. And, because I’m all about practical advice, I’m also throwing in seven pro tips to elevate your chainsaw game.

Stihl MS 310 vs. MS 390: A Head-to-Head Comparison

Choosing the right chainsaw can feel like navigating a dense forest. The Stihl MS 310 and MS 390 are both popular choices for homeowners and professionals alike, but they have distinct differences that can make one a better fit for your needs than the other. I’m going to break down everything from engine specs to real-world performance, so you can make an informed decision.

Engine Power and Performance

The heart of any chainsaw is its engine. Let’s examine what powers these two models:

• Stihl MS 310: This model features a 59cc engine. In my experience, this engine provides ample power for felling small to medium-sized trees, limbing, and bucking firewood.
• Stihl MS 390: The MS 390 boasts a slightly larger 64.1cc engine. This translates to more power, which is noticeable when tackling larger trees or denser wood.

Data Point: According to Stihl’s official specifications, the MS 390 produces approximately 15% more horsepower than the MS 310. This difference might seem small on paper, but it can significantly impact your cutting speed and overall efficiency, especially when dealing with hardwoods like oak or maple.

Personal Insight: I remember one particular job where I was cutting down a large oak tree with an MS 310. While it got the job done, it definitely struggled at times, requiring me to take multiple passes to get through the thick trunk. If I had been using an MS 390, I’m confident the job would have been completed much faster and with less strain on the saw and myself.

Weight and Handling

Weight is a critical factor, especially if you’re going to be using the chainsaw for extended periods. A heavier saw can lead to fatigue and reduced control.

• Stihl MS 310: Weighs approximately 13.0 lbs (5.9 kg) without the bar and chain.
• Stihl MS 390: Comes in at around 13.9 lbs (6.3 kg) without the bar and chain.

Technical Requirement: Always consider the weight of the bar and chain when evaluating the overall weight of the chainsaw. A longer bar and chain will naturally add more weight.

Practical Tip: When comparing the two, the MS 390 is noticeably heavier. While the extra power is beneficial, the added weight can be a drawback if you’re not used to handling heavier equipment. I recommend trying both saws to see which one feels more comfortable in your hands.

Bar Length Options

The bar length determines the maximum diameter of the wood you can cut. Both the MS 310 and MS 390 offer a range of bar length options.

• Stihl MS 310: Typically available with bar lengths ranging from 16 to 20 inches.
• Stihl MS 390: Can accommodate bar lengths from 16 to 25 inches.

Measurement Specification: When selecting a bar length, consider the average diameter of the wood you’ll be cutting. As a general rule, choose a bar length that is at least two inches longer than the diameter of the largest tree you expect to fell.

Case Study: In a project involving clearing a plot of land overgrown with small trees and brush, I found that a 16-inch bar on the MS 310 was perfect for the task. However, when I moved on to felling larger trees, I needed to switch to a longer bar on the MS 390 to handle the increased diameter.

Fuel and Oil Capacity

Fuel and oil capacity affect how long you can operate the chainsaw before needing to refuel or refill the oil reservoir.

• Stihl MS 310: Fuel capacity is approximately 18.6 oz (0.55 liters), and oil capacity is around 9.5 oz (0.28 liters).
• Stihl MS 390: Fuel capacity is slightly larger at 20.3 oz (0.6 liters), and oil capacity is about 10.1 oz (0.3 liters).

Best Practice: Always use a high-quality two-stroke oil mixed at the correct ratio (typically 50:1) to ensure optimal engine performance and longevity. I’ve seen too many engines fail prematurely due to using the wrong oil or an incorrect fuel mixture.

Anti-Vibration System

Prolonged chainsaw use can lead to hand-arm vibration syndrome (HAVS). An effective anti-vibration system is crucial for reducing fatigue and protecting your health.

• Stihl MS 310: Equipped with Stihl’s standard anti-vibration system, which uses rubber buffers to isolate the engine and cutting attachment from the handles.
• Stihl MS 390: Features a similar anti-vibration system, but some users report it being slightly more effective due to the saw’s overall design.

Safety Code: OSHA (Occupational Safety and Health Administration) has specific guidelines regarding vibration exposure in the workplace. It’s essential to take breaks and use proper techniques to minimize your risk of developing HAVS.

Cost Comparison

The initial cost is often a significant factor in the decision-making process. Here’s a general overview of the price range for these two models:

• Stihl MS 310: Typically ranges from $350 to $450, depending on the retailer and any included accessories.
• Stihl MS 390: Generally priced between $450 and $550.

Unique Insight: Keep in mind that prices can fluctuate based on seasonal sales, promotions, and local market conditions. It’s always a good idea to shop around and compare prices from different dealers before making a purchase. Also, consider the cost of replacement parts and maintenance when evaluating the long-term cost of ownership.

7 Pro Tips to Elevate Your Chainsaw Game

Now that we’ve covered the key differences between the Stihl MS 310 and MS 390, let’s move on to some pro tips that will help you get the most out of your chainsaw, regardless of the model you choose.

1. Master the Art of Chain Sharpening

A dull chain is not only inefficient but also dangerous. A sharp chain bites into the wood, allowing you to cut smoothly and safely. A dull chain, on the other hand, can kick back or bind, increasing the risk of accidents.

• Tool Requirement: Invest in a good quality chainsaw sharpening kit. These kits typically include a file, a depth gauge, and a filing guide.
• Step-by-Step Guide:
  1. Secure the chainsaw in a vise or on a stable surface.
  2. Use the file and filing guide to sharpen each cutter at the correct angle.
  3. Check the depth gauge and file it down if necessary.
  4. Rotate the chain and repeat the process for each cutter.

Personalized Storytelling: I’ll never forget the time I was trying to fell a tree with a dull chain. The saw kept bouncing and kicking back, and I ended up spending twice as long on the job as I should have. After that experience, I made it a point to always keep my chains sharp.

2. Choose the Right Bar and Chain Combination

The bar and chain combination you choose can significantly impact the performance and safety of your chainsaw.

• Specification: Match the bar length to the size of the wood you’ll be cutting. A longer bar is useful for felling larger trees, while a shorter bar is more maneuverable for limbing and bucking firewood.
• Material Type: Select the appropriate chain type for the type of wood you’ll be cutting. There are different chain designs for hardwoods, softwoods, and even dirty or abrasive wood.

Data-Backed Content: According to Oregon Products, a leading manufacturer of chainsaw chains, using the wrong chain type can reduce cutting efficiency by as much as 30% and increase the risk of chain breakage.

3. Maintain Proper Chain Tension

Proper chain tension is crucial for safe and efficient chainsaw operation. A chain that is too loose can derail, while a chain that is too tight can overheat and break.

• Procedure:
  1. Loosen the bar nuts.
  2. Use the chain tensioning screw to adjust the tension until the chain fits snugly against the bar.
  3. Tighten the bar nuts securely.
  4. Check the tension frequently during use and adjust as needed.

• Lubrication: Use a high-quality bar and chain oil to keep the chain properly lubricated. Check the oil level frequently and refill as needed.

Industry Standard: Most chainsaw manufacturers recommend using a bar and chain oil with a viscosity of SAE 30 or higher.

5. Practice Safe Felling Techniques

Felling trees can be dangerous if you don’t follow proper safety procedures.

• Wood Selection Criteria: Before felling a tree, assess its size, lean, and any potential hazards such as dead branches or power lines.
• Cutting Pattern: Use the appropriate cutting pattern, such as the open-face notch or the Humboldt notch, to control the direction of the fall.
• Safety Equipment Requirements: Always wear appropriate safety gear, including a hard hat, safety glasses, hearing protection, and chainsaw chaps.

Original Research: In a study conducted by the National Institute for Occupational Safety and Health (NIOSH), it was found that improper felling techniques are a leading cause of chainsaw-related injuries.

6. Store Your Chainsaw Properly

Proper storage is essential for preventing damage and ensuring that your chainsaw is ready to use when you need it.

• Procedure:
  1. Drain the fuel tank or add a fuel stabilizer.
  2. Remove the bar and chain and clean them thoroughly.
  3. Store the chainsaw in a dry, well-ventilated area.
  4. Cover the bar and chain to protect them from rust and corrosion.

Technical Limitations: Avoid storing your chainsaw in direct sunlight or in areas where it may be exposed to extreme temperatures.

7. Understand Wood Moisture Content for Firewood

If you’re using your chainsaw to prepare firewood, it’s crucial to understand the importance of wood moisture content.

• Material Specifications: Freshly cut wood can have a moisture content of 50% or higher. For optimal burning, firewood should be seasoned to a moisture content of 20% or less.
• Drying Tolerances: Seasoning firewood typically takes 6 to 12 months, depending on the type of wood and the climate.

Data Points and Statistics: According to the U.S. Department of Energy, burning unseasoned firewood can reduce heating efficiency by as much as 50% and increase the risk of chimney fires.

Practical Examples: To test the moisture content of firewood, use a moisture meter. These devices are readily available and can provide accurate readings. Alternatively, you can split a piece of firewood and examine the freshly exposed surface. If it feels cool and damp, it’s likely still too wet to burn.

Conclusion: Making the Right Choice

Choosing between the Stihl MS 310 and MS 390 ultimately depends on your specific needs and budget. If you’re primarily cutting small to medium-sized trees and bucking firewood, the MS 310 is a solid choice. However, if you frequently tackle larger trees or denser wood, the extra power of the MS 390 may be worth the investment.

Remember, no matter which chainsaw you choose, proper maintenance, safe operating procedures, and a healthy dose of respect for the power of the tool are essential for ensuring your safety and maximizing the lifespan of your equipment. So get out there, get cutting, and stay safe!
