Stihl 250 Specs (5 Expert Tips) for Efficient Firewood Cutting

Why did the tree go to the dentist? Because it needed a root canal!

Let’s talk about the Stihl MS 250. This chainsaw is a workhorse, a real contender in the world of firewood cutting. But before you start dreaming of cozy winter nights by the fire, let’s get real about the costs involved in turning that Stihl 250 into a firewood-generating machine. I’m going to share my experiences, some hard-won lessons, and a whole lot of data to help you budget effectively and get the most out of your firewood endeavors.

Stihl MS 250 Specs and Why They Matter for Firewood

The Stihl MS 250 is a mid-range chainsaw, popular for its balance of power, weight, and price.

• Engine: Typically around 45.4 cc, delivering decent power for its size.
• Power Output: Around 2.3 kW (3.1 bhp). This is enough for felling smaller trees and bucking medium-sized logs.
• Weight: Around 10.1 lbs (without fuel and bar). This is manageable for extended use.
• Bar Length: Usually available in 16″ or 18″. I personally prefer the 18″ for a little extra reach, but the 16″ is more maneuverable.
• Fuel Capacity: Around 15.2 oz. Keep extra fuel on hand!
• Oil Capacity: Around 8.5 oz. Use a quality bar and chain oil.

Why do these specs matter? The engine size dictates how large of a log you can realistically cut without bogging down. The weight affects how long you can comfortably work before fatigue sets in. The bar length determines the maximum diameter of the wood you can safely cut in a single pass.

5 Expert Tips for Efficient Firewood Cutting with the Stihl MS 250

Before we dive into the nitty-gritty of costs, let’s talk about maximizing the efficiency of your Stihl MS 250 for firewood cutting. These tips will not only save you time but also reduce wear and tear on your saw, ultimately saving you money in the long run.

Tip 1: Chain Sharpening is King

A dull chain is a hungry chain. It forces you to work harder, puts more strain on the engine, and wastes fuel. I cannot stress this enough: sharpen your chain frequently. I usually sharpen mine after every tank of gas, or even more often if I’m cutting dirty wood.

• How to sharpen: You can use a file and guide, or an electric chain sharpener. I use both, depending on the situation. The file is great for quick touch-ups in the field, while the electric sharpener is faster for more extensive sharpening.
• Angle and Depth: Pay attention to the correct filing angle and depth. Consult your Stihl manual for the specific recommendations for your chain.
• Cost Savings: A sharp chain reduces fuel consumption by up to 20% and extends the life of your bar and chain.

Tip 2: Proper Tension is Your Friend

A loose chain is a dangerous chain. It can derail, causing damage to the saw and potentially injuring you. A chain that is too tight puts excessive strain on the bar and engine.

• Checking Tension: Check the chain tension frequently, especially when the chain is new. The chain should be snug against the bar, but you should still be able to pull it around by hand.
• Adjusting Tension: Adjust the tension with the adjustment screw on the side of the saw. Make small adjustments and check the tension frequently.
• Cost Savings: Proper tension prevents premature wear on the bar, chain, and sprocket, saving you money on replacements.

Tip 3: Use the Right Fuel Mix

The Stihl MS 250 requires a specific fuel-to-oil ratio. Using the wrong mix can lead to engine damage and reduced performance.

• Ratio: Typically, it’s a 50:1 ratio (gasoline to 2-cycle oil). Always use high-quality 2-cycle oil specifically designed for air-cooled engines.
• Mixing: I always mix my fuel in a separate container using a measuring cup or ratio rite. Never mix fuel directly in the saw’s tank.
• Fuel Stabilizer: If you’re not going to use the fuel within a month, add a fuel stabilizer to prevent the gasoline from going bad.
• Cost Savings: Using the correct fuel mix prevents costly engine repairs and extends the life of your saw.

Tip 4: Limbing Techniques for Efficiency

Limbing is the process of removing branches from a felled tree. Efficient limbing can significantly speed up your firewood cutting process.

• Work from the Bottom Up: Start by removing the branches on the underside of the tree, working your way up. This allows you to use the trunk as a support.
• Use the Saw’s Momentum: Let the saw’s weight do the work. Don’t force it.
• Be Aware of Pinch Points: Watch out for branches that are under tension. These can pinch the bar and chain, causing the saw to kick back.
• Cost Savings: Efficient limbing reduces the amount of time you spend cutting, saving fuel and reducing wear and tear on your saw.

Tip 5: Felling Techniques for Safety and Wood Optimization

Felling a tree is a dangerous task. It’s crucial to use proper techniques to ensure your safety and maximize the amount of usable wood.

• Assess the Tree: Before felling, assess the tree for lean, wind direction, and any potential hazards such as dead branches or power lines.
• Plan Your Escape Route: Always have a clear escape route planned before you start cutting.
• Use Proper Felling Cuts: Use a combination of the undercut, back cut, and felling wedge to control the direction of the fall.
• Leave a Hinge: Leave a hinge of wood between the undercut and back cut to guide the tree’s fall.
• Cost Savings: Safe and controlled felling prevents damage to the saw, reduces the risk of injury, and maximizes the amount of usable wood.

The Real Cost of Firewood: A Deep Dive

Now for the part you’ve been waiting for: the cost breakdown. Firewood may seem like a cheap way to heat your home, but the true cost can be surprising. I’ve broken down the costs into several categories, and I’ll share my own experiences and insights along the way.

1. The Cost of the Wood Itself

This is often the biggest variable. Are you buying logs, felling your own trees, or scavenging deadwood? The cost will vary dramatically.

• Buying Logs: The price of logs depends on the species, size, and quality. Hardwoods like oak and maple are more expensive than softwoods like pine and fir. Expect to pay anywhere from \$50 to \$200 per cord for logs, depending on your location and the current market. I’ve seen prices fluctuate wildly based on demand and availability. During a particularly cold winter, prices can easily double.
  • Data Point: According to the USDA Forest Service, the average price of delivered firewood in the US ranges from \$150 to \$400 per cord, depending on the region and species.
• Felling Your Own Trees: This is where it gets tricky. You may think it’s “free” wood, but there are still costs involved.
  • Permits: Depending on your location, you may need a permit to fell trees, even on your own property. These permits can range from a few dollars to hundreds of dollars, depending on the size and scope of the project.
  • Land Access: If you don’t own the land, you’ll need permission from the landowner. They may charge you a fee for the wood.
  • Transportation: Getting the logs out of the woods can be a challenge. You may need a tractor, truck, or even a skidder. These can be expensive to rent or purchase.
• Scavenging Deadwood: This is the cheapest option, but it’s also the most time-consuming. You’ll need to search for suitable deadwood, cut it to size, and haul it home. The quality of the wood may also be questionable.
  • My Experience: I’ve scavenged deadwood for years, and I’ve learned that it’s not always as easy as it seems. You have to be careful about the wood you choose. Some deadwood is rotten or infested with insects.

2. The Cost of the Stihl MS 250 and Related Equipment

The initial purchase price of the chainsaw is just the beginning. You’ll also need to factor in the cost of accessories, maintenance, and repairs.

• Chainsaw Price: The Stihl MS 250 typically costs between \$400 and \$500 new. Used models can be found for less, but be sure to inspect them carefully before buying.
• Bar and Chain: You’ll need a good quality bar and chain. Expect to pay around \$50 to \$100 for a new bar and chain. I recommend having at least two chains on hand so you can always have a sharp one ready to go.
• Safety Gear: Safety gear is essential. This includes a helmet, eye protection, ear protection, gloves, and chaps. Expect to pay around \$100 to \$200 for a complete set of safety gear. I’ve seen too many accidents to take safety lightly.
• Maintenance: Chainsaws require regular maintenance. This includes cleaning, sharpening, and lubricating. You’ll also need to replace parts such as spark plugs, air filters, and fuel filters.
  • Chain Sharpening Equipment: As mentioned earlier, you’ll need equipment to sharpen your chain. A file and guide will cost around \$20 to \$30, while an electric chain sharpener will cost around \$50 to \$150.
  • Bar and Chain Oil: You’ll need to use bar and chain oil to lubricate the bar and chain. A gallon of oil will cost around \$15 to \$25.
  • Fuel and Oil: As mentioned earlier, you’ll need to use a specific fuel-to-oil ratio. A gallon of 2-cycle oil will cost around \$20 to \$30.
• Repairs: Chainsaws can break down. Be prepared to pay for repairs. A simple repair, such as replacing a spark plug, may only cost a few dollars. But a more complex repair, such as rebuilding the engine, can cost hundreds of dollars.
  • My Experience: I once had to replace the carburetor on my chainsaw. The part itself only cost about \$30, but the labor to install it was over \$100.

3. The Cost of Splitting and Stacking

Once you’ve cut the wood to size, you’ll need to split it and stack it. This can be done manually or with a machine.

• Manual Splitting: This requires a splitting axe or maul. A good quality splitting axe will cost around \$50 to \$100. It’s hard work, but it’s a good workout!
• Hydraulic Splitter: A hydraulic splitter can make splitting wood much easier. A gas-powered splitter will cost around \$1,000 to \$3,000. An electric splitter will cost around \$500 to \$1,500.
  • Rental Costs: You can also rent a hydraulic splitter. Rental costs typically range from \$50 to \$100 per day.
• Stacking: Stacking firewood is important for proper drying. It also takes time and effort. You’ll need a place to stack the wood, and you’ll need to stack it in a way that allows for good air circulation.

4. The Cost of Drying and Storage

Firewood needs to be properly dried before it can be burned. This can take anywhere from six months to a year, depending on the species of wood and the climate.

• Drying Time: Hardwoods like oak and maple take longer to dry than softwoods like pine and fir.
• Storage: You’ll need a place to store the firewood while it’s drying. This could be a woodshed, a tarp, or simply a well-ventilated area.
• Moisture Meter: A moisture meter can help you determine when the firewood is dry enough to burn. A good quality moisture meter will cost around \$30 to \$50.
  • Ideal Moisture Content: The ideal moisture content for firewood is around 20%.

5. The Cost of Labor

If you’re doing all the work yourself, you may not think about the cost of labor. But your time is valuable.

• Opportunity Cost: Consider what else you could be doing with your time. If you’re spending 40 hours cutting and splitting firewood, that’s 40 hours you’re not spending on other things.
• Hiring Help: If you don’t have the time or energy to do all the work yourself, you can hire someone to help you. Expect to pay around \$20 to \$30 per hour for labor.

Case Study: My Firewood Budget

To give you a better idea of the costs involved, let’s look at a case study. This is my own firewood budget for this year.

• Wood Source: I’m felling my own trees on my property.
• Equipment: I already own a Stihl MS 250, a splitting axe, and safety gear.
• Labor: I’m doing all the work myself.

Here’s a breakdown of my estimated costs:

• Permits: \$0 (I don’t need a permit in my location)
• Fuel and Oil: \$50
• Bar and Chain Oil: \$20
• Chain Sharpening: \$10 (for files)
• Maintenance: \$20 (for spark plugs and air filters)
• Total: \$100

I estimate that I’ll be able to cut and split about 3 cords of firewood this year. So my cost per cord is around \$33. This is significantly cheaper than buying firewood, which would cost me around \$250 per cord in my area.

Global Firewood Market Trends and Pricing

Firewood prices and availability vary significantly around the world. Factors such as climate, forest resources, and local regulations all play a role.

• Europe: In many parts of Europe, firewood is a popular heating source. Prices are generally higher than in the US, due to stricter regulations and higher demand.
  • Data Point: In some European countries, the price of firewood can be as high as €300 per cord.
• Asia: In some parts of Asia, firewood is still the primary source of fuel for cooking and heating. Prices are generally lower than in the US and Europe, due to lower labor costs and less stringent regulations.
• Africa: In many parts of Africa, firewood is a critical resource for survival. Deforestation is a major problem, and firewood prices are often very high due to scarcity.
• North America: Firewood prices in North America vary widely depending on the region. Prices are generally higher in urban areas and in areas with limited forest resources.

Cost Optimization Strategies for Firewood Preparation

Now that you have a better understanding of the costs involved, let’s talk about some strategies for optimizing your budget.

• Buy in Bulk: If you’re buying logs, try to buy in bulk. You’ll often get a better price per cord.
• Season Wood Properly: Properly seasoned wood burns more efficiently, saving you money on fuel.
• Maintain Your Equipment: Regular maintenance can prevent costly repairs and extend the life of your equipment.
• Shop Around for Prices: Don’t just buy the first firewood you see. Shop around and compare prices from different suppliers.

• Take Advantage of Government Programs: Some governments offer programs to help homeowners reduce their heating costs. These programs may include rebates for energy-efficient appliances or subsidies for firewood.

Calculations and Formulas for Firewood Management

Here are some useful calculations and formulas for managing your firewood supply:

• Calculating Volume of Logs:
  • Board Feet: (Length in feet x Width in inches x Thickness in inches) / 12
  • Cords: A cord is a stack of wood that measures 4 feet high, 4 feet wide, and 8 feet long, for a total volume of 128 cubic feet.
• Estimating Drying Time: Drying time depends on several factors, including the species of wood, the climate, and the stacking method. As a general rule, hardwoods take longer to dry than softwoods. In a dry climate, firewood may dry in as little as six months. In a humid climate, it may take a year or more.
• Estimating BTU Output: The BTU (British Thermal Unit) output of firewood depends on the species of wood and its moisture content. Dry hardwoods generally have a higher BTU output than softwoods.
