Stihl MS310 Chain Size Guide (3 Pro Tips for Bar Upgrades)

Isn’t it ironic? We spend ages felling trees, only to burn some of them for warmth in our homes. It’s a cycle, a dance between resource and need, and in that dance, the Stihl MS310 chainsaw plays a pivotal role for many. Now, you might think picking a chain for a chainsaw is as simple as grabbing the first one that looks right. Trust me, it’s not. The wrong chain can turn your MS310 from a wood-devouring beast into a dull, frustrating paperweight. And if you’re thinking about upgrading your bar, you’re stepping into a world of performance gains… and potential pitfalls. So, let’s dive deep into the Stihl MS310 chain size guide and explore those pro tips for bar upgrades. We’ll also be talking about how all this impacts your wallet, because let’s be honest, no one wants to break the bank just to keep their firewood stack high.

Stihl MS310 Chain Size Guide: Unleashing the Beast Within

The Stihl MS310 is a workhorse. I’ve personally used one for years, felling everything from stubborn oaks to pesky pines. It’s a reliable saw, but like any tool, its performance hinges on the right setup. The chain is arguably the most crucial component.

Understanding the Stock Chain Size

The stock chain for the Stihl MS310 typically comes in a .325″ pitch, .063″ gauge, and 74 drive links for a 20-inch bar. Let’s break down what each of these terms means:

• Pitch: This is the distance between any three consecutive rivets on the chain, divided by two. In simpler terms, it’s the size of the chain. A .325″ pitch is a common size, offering a good balance between cutting speed and durability.
• Gauge: This refers to the thickness of the drive links, the little tabs that fit into the bar groove. A .063″ gauge is also quite common and ensures a snug fit within the bar.
• Drive Links: These are the individual links that propel the chain around the bar. The number of drive links depends on the bar length. A 20-inch bar usually requires 74 drive links, but always double-check your specific bar.

Why is this important?

Using the wrong chain size can lead to:

• Poor cutting performance: The saw will bog down, cut unevenly, or simply refuse to cut.
• Premature wear and tear: The chain and bar will wear out faster, costing you money in the long run.
• Safety hazards: An improperly sized chain can increase the risk of chain breakage or kickback.

Cost Implications:

Buying the wrong chain is like throwing money into a wood chipper. A decent chain for the MS310 will set you back around $30-$50. Imagine buying the wrong one twice – that’s already $60-$100 down the drain. I’ve made that mistake myself, back when I thought all chains were created equal. Let me tell you, the frustration of a chain that doesn’t fit is not worth the few bucks you might save by not checking the specs.

Pro Tip #1: Know Your Bar Length

The bar length dictates the number of drive links you need. While a 20-inch bar is common, you might have a different size. Always measure your bar or consult the manufacturer’s specifications to determine the correct number of drive links.

Data Point: Stihl’s official website provides detailed specifications for all their bars, including the recommended chain size.

Cost Considerations:

A longer bar means more chain, which translates to a higher cost. For example, a 20-inch chain might cost $40, while a 25-inch chain could easily be $55 or more. But don’t just blindly go for the longest bar you can find. A longer bar requires more power, and if your MS310 is already working hard, it might not be able to handle the extra load. This can lead to slower cutting speeds and increased fuel consumption, effectively costing you more in the long run.

Pro Tip #2: Choosing the Right Chain Type

Not all chains are created equal. There are different types of chains designed for specific cutting tasks. Here are a few common types:

• Full Chisel: These chains have square-cornered cutters that are aggressive and fast-cutting. They are ideal for clean wood but dull quickly in dirty or frozen wood.
• Semi-Chisel: These chains have rounded cutters that are more durable than full chisel chains. They are a good all-around choice for cutting a variety of wood types.
• Low-Profile (Safety) Chains: These chains have a reduced kickback risk, making them a good choice for beginners or those who prioritize safety.
• Ripping Chains: Designed specifically for milling logs lengthwise. The teeth are ground at a different angle for more efficient ripping.

My Experience: I once tried using a full chisel chain on a pile of reclaimed wood that was riddled with dirt and nails. The chain dulled almost instantly, and I spent more time sharpening than cutting. Lesson learned: choose the right chain for the job.

Cost Analysis:

Full chisel chains are often more expensive than semi-chisel chains, typically costing around $5-$10 more. However, if you’re cutting clean wood, the increased cutting speed can save you time and fuel, potentially offsetting the higher cost. On the other hand, if you’re cutting dirty wood, a semi-chisel chain will last longer and require less frequent sharpening, making it the more economical choice. Ripping chains are the most specialized and therefore usually the most expensive, costing upwards of $60 for a chain suitable for the MS310.

Data Point: According to a survey conducted by Arbor Age magazine, professional arborists prefer semi-chisel chains for general use due to their versatility and durability.

Pro Tip #3: Bar Upgrades: Stepping Up Your Game

Upgrading your bar can significantly improve the performance of your MS310. Here are a few factors to consider:

• Bar Length: As mentioned earlier, a longer bar allows you to cut larger trees, but it also requires more power.
• Bar Type: Different bar types are designed for different applications. Solid bars are durable and long-lasting, while laminated bars are lighter and more affordable.
• Sprocket Nose vs. Hard Nose: Sprocket nose bars have a replaceable sprocket at the tip, which reduces friction and wear. Hard nose bars are more durable but generate more friction.

Cost Breakdown of Bar Upgrades:

• Laminated Bar: A 20-inch laminated bar for the MS310 typically costs around $40-$60.
• Solid Bar: A 20-inch solid bar can range from $70-$100 or more, depending on the brand and quality.
• Sprocket Nose Bar: A 20-inch sprocket nose bar usually costs between $80-$120, plus the cost of replacement sprockets.

My Recommendation: If you’re primarily cutting firewood, a laminated bar is a good choice. It’s lightweight, affordable, and durable enough for most tasks. However, if you’re doing heavy-duty logging or milling, a solid bar is a better investment. The added durability will pay off in the long run. If you are milling with the MS310, I would suggest upgrading to a ripping chain at the same time.

Cost Optimization:

Before upgrading your bar, consider the overall cost. A new bar might seem like a good investment, but you also need to factor in the cost of a new chain, as well as the potential increase in fuel consumption and maintenance. Sometimes, it’s more cost-effective to simply maintain your existing bar and chain properly.

The Hidden Costs: Maintenance and Sharpening

Don’t forget about the hidden costs of chainsaw ownership: maintenance and sharpening. A dull chain is not only inefficient, but it’s also dangerous.

Sharpening:

• Hand Sharpening: This is the most affordable option, but it requires skill and practice. A good sharpening kit will cost around $20-$30.
• Professional Sharpening: This is the most convenient option, but it can be expensive. A professional sharpening service typically charges $10-$15 per chain.
• Electric Chain Sharpener: This is a good compromise between cost and convenience. A decent electric chain sharpener will set you back around $50-$100.

Maintenance:

• Chain Oil: This is essential for lubricating the chain and bar. A gallon of chain oil typically costs around $15-$20.
• Air Filter: A clean air filter ensures proper engine performance. Replacement air filters cost around $5-$10.
• Spark Plug: A new spark plug can improve starting and performance. Spark plugs cost around $5-$10.

Cost-Saving Tips:

• Learn to sharpen your own chains: This will save you money in the long run. There are plenty of online tutorials and videos that can teach you the basics.
• Clean your air filter regularly: This will prevent the engine from overheating and improve fuel efficiency.
• Use high-quality chain oil: This will prolong the life of your chain and bar.

Data Point: According to a study by the U.S. Forest Service, proper chainsaw maintenance can reduce fuel consumption by up to 20%.

Budgeting for Firewood: A Case Study

Let’s put all this information into practice with a case study on budgeting for firewood. Suppose you want to cut and split 5 cords of firewood for the winter. Here’s a breakdown of the potential costs:

Material Costs (Wood)

• Free Wood: If you have access to free wood, such as fallen trees on your property, your material costs will be minimal. However, you’ll still need to factor in the cost of transporting the wood.
• Purchased Wood: If you need to purchase wood, the cost will vary depending on the species, quality, and location. A cord of seasoned hardwood typically costs between $200-$400.

Cost Calculation:

• 5 cords of purchased hardwood @ $300/cord = $1500

Tool Costs

• Chainsaw (MS310): You already own the chainsaw, so there’s no initial cost. However, you’ll need to factor in the cost of fuel, chain oil, and maintenance.
• Chain: You’ll need at least one new chain for this project. A good quality chain will cost around $40.
• Splitting Maul or Hydraulic Splitter: A splitting maul is a manual option that costs around $50-$70. A hydraulic splitter is faster and easier, but it’s also more expensive, ranging from $500-$2000.

Cost Calculation:

• Chain: $40
• Splitting Maul: $60 (or Hydraulic Splitter rental: $75/day)

Labor Costs

• Your Own Labor: If you’re doing all the work yourself, you won’t have any direct labor costs. However, you should factor in the value of your time.
• Hired Labor: If you hire someone to help you, the cost will vary depending on their experience and the going rate in your area. Labor costs typically range from $20-$40 per hour.

Cost Calculation:

• Your labor: (Consider the value of your time – even if you aren’t paying for labour directly, time is money)
• Hired labor: (If applicable, calculate based on hourly rate and estimated hours)

Other Costs

• Fuel: Chainsaw fuel and splitter fuel can add up quickly. A gallon of fuel typically costs around $4-$5.
• Chain Oil: As mentioned earlier, chain oil costs around $15-$20 per gallon.
• Safety Gear: You’ll need safety glasses, gloves, and chaps. These items typically cost around $50-$100.

Cost Calculation:

• Fuel: $50 (estimate)
• Chain Oil: $30 (estimate)
• Safety Gear: $75 (if needed)
• Permits: (If applicable, research local requirements)

Total Cost Estimate

Based on these estimates, the total cost of cutting and splitting 5 cords of firewood could range from $1755 (if you have free wood and do all the work yourself with a splitting maul) to over $3600 (if you purchase wood, hire labor, and rent a hydraulic splitter).

Cost Optimization Strategies:

• Source free wood: Look for fallen trees on your property or ask local landowners for permission to cut firewood on their land.
• Do the work yourself: This will save you a significant amount of money on labor costs.
• Use a splitting maul: This is a more affordable option than renting a hydraulic splitter.
• Buy fuel and chain oil in bulk: This will save you money in the long run.
• Maintain your equipment properly: This will prolong the life of your equipment and reduce the need for repairs.

Data Point: According to the U.S. Energy Information Administration, the average household spends around $1000 per year on heating fuel. Cutting your own firewood can save you a significant amount of money on your heating bill.

Calculating Volume: Board Feet and Cords

Understanding how to calculate the volume of logs and firewood is crucial for accurate budgeting and cost management.

Board Feet

A board foot is a unit of measurement for lumber, defined as a piece of wood that is 1 inch thick, 12 inches wide, and 12 inches long.

Formula for Calculating Board Feet:

• (Thickness in inches) x (Width in inches) x (Length in inches) / 144

Example:

• A board that is 2 inches thick, 8 inches wide, and 10 feet long contains:
  • (2 x 8 x 120) / 144 = 13.33 board feet

Cords

A cord is a unit of measurement for firewood, defined as a stack of wood that is 4 feet high, 4 feet wide, and 8 feet long.

Formula for Estimating Cords:

• (Length in feet) x (Width in feet) x (Height in feet) / 128

Example:

• A stack of firewood that is 6 feet high, 8 feet wide, and 16 feet long contains:
  • (6 x 8 x 16) / 128 = 6 cords

Practical Considerations:

• These are estimates. The actual volume of wood in a cord can vary depending on the size and shape of the logs.
• When purchasing firewood, be sure to ask the supplier how they measure a cord.

Estimating Drying Time: Moisture Content

The moisture content of wood significantly affects its burning efficiency and heat output. Seasoned firewood (dried to a moisture content of 20% or less) burns much hotter and cleaner than green firewood (freshly cut wood with a moisture content of 50% or more).

Factors Affecting Drying Time:

• Species: Hardwoods like oak and maple take longer to dry than softwoods like pine and fir.
• Climate: Wood dries faster in warm, sunny, and windy climates.
• Stacking Method: Stacking wood in a way that allows for good air circulation will speed up the drying process.
• Log Size: Smaller logs dry faster than larger logs.

Estimating Drying Time:

• As a general rule, hardwoods typically take 6-12 months to dry, while softwoods take 3-6 months.
• Use a moisture meter to accurately measure the moisture content of your firewood.

Cost Implications:

• Burning green firewood can lead to creosote buildup in your chimney, which can increase the risk of chimney fires.
• Burning green firewood is also less efficient, meaning you’ll need to burn more wood to generate the same amount of heat.
