Let’s delve a bit deeper into what these specs mean and how they impact performance.

Understanding Key Specifications

• Engine Displacement and Power Output: The 55.5cc engine and 3.5hp power output strike a good balance between power and weight. This is sufficient for cutting through most hardwoods and softwoods commonly found in residential and forestry settings. I’ve personally used it to fell trees up to 16 inches in diameter without significant issues.
• Recommended Bar Length: The 13-18 inch bar length range is ideal for versatility. A shorter bar (13-16 inches) is great for limbing and smaller tasks, providing better maneuverability. A longer bar (18 inches) offers increased reach for felling larger trees. I typically use a 16-inch bar for most of my firewood cutting.
• Weight: At 12.8 lbs, the 2255 is relatively lightweight for its power. This reduces fatigue during extended use, which is a significant factor when processing large quantities of wood.
• Chain Pitch and Gauge: The .325″ pitch and .058″ gauge are standard for chainsaws in this class. Ensure you use the correct chain type for optimal performance and safety. Using the wrong chain can lead to premature wear and increased risk of kickback.
• Sound Levels: Chainsaws are inherently noisy. The Jonsered 2255 is no exception. Always wear proper hearing protection when operating a chainsaw. I prefer earmuffs with a Noise Reduction Rating (NRR) of at least 25 dB.
• Vibration Levels: High vibration levels can lead to hand-arm vibration syndrome (HAVS). The 2255 features vibration dampening technology, but it’s still important to take frequent breaks and maintain a firm but relaxed grip on the saw.

Jonsered 2255 vs. Competitors

To put these specs in perspective, let’s compare the Jonsered 2255 to a few similar chainsaws from other manufacturers:

As you can see, the Jonsered 2255 is competitively priced and offers similar performance to its rivals. The Stihl MS 271 boasts slightly more power, but it also comes with a higher price tag. The Husqvarna 455 Rancher is very similar in specs and price, making it a close competitor. Ultimately, the best choice depends on personal preference, brand loyalty, and availability of service and parts in your area. In my experience, the Jonsered 2255 offers a great balance of performance and value.

5 Expert Tips for Efficient Logging with the Jonsered 2255

Now that we’ve covered the specifications, let’s move on to practical tips for efficient logging with the Jonsered 2255. These tips are based on my years of experience in wood processing and are designed to help you work safely, efficiently, and effectively.

1. Proper Chain Maintenance: The Key to Performance

A sharp chain is the single most important factor in chainsaw performance. A dull chain not only cuts slower but also requires more effort, increases the risk of kickback, and puts unnecessary strain on the engine.

• Sharpen Regularly: I recommend sharpening your chain after every two to three tanks of fuel, or more often if you’re cutting dirty or abrasive wood.
• Use the Right Tools: Invest in a good quality chainsaw file and a filing guide. A filing guide helps you maintain the correct angle and depth of the cutters. I personally use a Stihl 2-in-1 Easy File, which sharpens both the cutters and the depth gauges simultaneously.
• Maintain the Depth Gauges: The depth gauges (also known as rakers) control how much the cutters bite into the wood. If the depth gauges are too high, the chain won’t cut effectively. If they’re too low, the chain will grab and kickback. Use a depth gauge tool and a flat file to maintain the correct depth gauge setting. The recommended setting for most chains is .025″-.030″.
• Clean and Inspect the Chain: Regularly clean your chain with kerosene or a citrus-based cleaner to remove pitch and debris. Inspect the chain for damage, such as cracked cutters or loose rivets. Replace the chain if it’s excessively worn or damaged.
• Tension the Chain Properly: A properly tensioned chain will sag slightly on the bottom of the bar but should still be snug enough to pull around by hand. Overtightening the chain can cause excessive wear on the bar and chain, while undertightening can lead to the chain derailing. Check the chain tension frequently, especially when the chain is new, as it will stretch during the initial break-in period.

Personal Story: I once spent an entire day struggling to cut through a pile of oak logs with a dull chain. I was frustrated, exhausted, and getting nowhere fast. Finally, I took the time to properly sharpen the chain, and the difference was night and day. The saw cut through the wood like butter, and I was able to finish the job in a fraction of the time. This experience taught me the importance of chain maintenance and the value of taking the time to do it right.

2. Choose the Right Bar and Chain Combination

The Jonsered 2255 can accommodate bar lengths ranging from 13 to 18 inches. The optimal bar length depends on the size of the wood you’re cutting and your personal preference.

• Shorter Bars (13-16 inches): These are ideal for limbing, pruning, and cutting smaller diameter wood. They offer better maneuverability and are less tiring to use for extended periods.
• Longer Bars (18 inches): These are better suited for felling larger trees and bucking larger logs. They provide increased reach and cutting capacity.
• Chain Type: There are several different types of chainsaw chains available, each designed for specific applications.
  • Full Chisel Chains: These have square-cornered cutters that are very aggressive and cut quickly. They are best suited for clean wood and experienced users.
  • Semi-Chisel Chains: These have rounded-corner cutters that are more durable and less prone to damage from dirty wood. They are a good all-around choice for most users.
  • Low-Kickback Chains: These have special features that reduce the risk of kickback. They are a good choice for beginners and those who are concerned about safety.

Case Study: I recently worked on a project where I needed to fell a number of small to medium-sized pine trees. I initially used an 18-inch bar, but I found it to be cumbersome and unnecessary for the size of the trees. I switched to a 14-inch bar with a semi-chisel chain, and the difference was significant. The saw was much easier to maneuver, and I was able to work more quickly and efficiently. This experience reinforced the importance of choosing the right bar and chain combination for the specific task at hand.

3. Master Proper Felling Techniques

Felling a tree safely and efficiently requires careful planning and execution. Here are some key steps to follow:

• Assess the Tree: Before you start cutting, assess the tree for lean, wind direction, and any potential hazards, such as dead branches or power lines.
• Plan Your Escape Route: Identify a clear escape route that is at a 45-degree angle away from the direction of the fall.
• Make the Notch Cut: The notch cut determines the direction of the fall. It should be a V-shaped cut with an opening angle of about 70-90 degrees. The depth of the notch should be about 1/5 to 1/3 of the tree’s diameter.
• Make the Felling Cut: The felling cut is made on the opposite side of the tree from the notch cut. Leave a hinge of uncut wood to control the direction of the fall. The hinge should be about 1/10 of the tree’s diameter.
• Use Wedges: If the tree is leaning in the wrong direction or if you’re concerned about it falling prematurely, use felling wedges to help guide the fall. Insert the wedges into the felling cut and drive them in with a sledgehammer.
• Communicate: If you’re working with a partner, communicate clearly and use hand signals to coordinate your actions.
• Clear the Area: Before the tree falls, make sure the area is clear of people and obstacles.

Data and Insights: According to the Occupational Safety and Health Administration (OSHA), improper felling techniques are a leading cause of logging accidents. Taking the time to learn and practice proper felling techniques can significantly reduce your risk of injury. I’ve personally witnessed several near-misses due to improper felling, and these experiences have reinforced the importance of prioritizing safety above all else.

4. Optimize Fuel and Oil Mixtures

The Jonsered 2255 is a two-stroke engine, which means it requires a mixture of gasoline and oil to lubricate the engine. Using the correct fuel and oil mixture is crucial for engine performance and longevity.

• Use High-Quality Gasoline: Use gasoline with an octane rating of 89 or higher. Avoid using gasoline that contains ethanol, as ethanol can damage the engine. If you must use gasoline with ethanol, use a fuel stabilizer to protect the engine.
• Use Two-Stroke Oil: Use a high-quality two-stroke oil that is specifically designed for air-cooled engines. I recommend using a synthetic oil, as it provides better lubrication and reduces carbon buildup.
• Mix the Fuel and Oil Correctly: Follow the manufacturer’s recommendations for the fuel and oil mixture ratio. The Jonsered 2255 typically requires a 50:1 mixture ratio (50 parts gasoline to 1 part oil). Use a measuring container to ensure accurate mixing.
• Store Fuel Properly: Store fuel in a clean, airtight container. Label the container clearly and store it in a cool, dry place away from heat and open flames.
• Use Fresh Fuel: Fuel can degrade over time, especially if it contains ethanol. Use fresh fuel whenever possible. If you’re storing fuel for an extended period, add a fuel stabilizer to prevent degradation.

Practical Example: I once had a chainsaw engine seize up due to using the wrong fuel and oil mixture. I had accidentally used a four-stroke oil instead of a two-stroke oil, and the engine didn’t get enough lubrication. This resulted in significant damage to the engine and required a costly repair. This experience taught me the importance of paying close attention to the fuel and oil mixture and using the correct products.

5. Prioritize Safety: Gear Up and Stay Alert

Chainsaw operation is inherently dangerous. Always prioritize safety by wearing appropriate personal protective equipment (PPE) and following safe operating procedures.

• Wear Proper PPE:
  • Helmet: Protects your head from falling branches and debris.
  • Eye Protection: Protects your eyes from flying wood chips. I recommend wearing safety glasses or a face shield.
  • Hearing Protection: Protects your ears from the loud noise of the chainsaw. I prefer earmuffs with a Noise Reduction Rating (NRR) of at least 25 dB.
  • Gloves: Protect your hands from cuts and abrasions.
  • Chaps: Protect your legs from chainsaw cuts. Chainsaw chaps are made of ballistic nylon fibers that are designed to jam the chain and stop it from cutting through.
  • Steel-Toed Boots: Protect your feet from falling logs and other hazards.
• Inspect Your Chainsaw: Before each use, inspect your chainsaw for damage and ensure that all components are in good working order. Check the chain tension, the fuel and oil levels, and the throttle trigger.
• Maintain a Safe Distance: Keep a safe distance from other people when operating a chainsaw. A good rule of thumb is to maintain a distance of at least two tree lengths.
• Be Aware of Your Surroundings: Pay attention to your surroundings and be aware of any potential hazards, such as uneven terrain, slippery surfaces, or overhead obstructions.
• Take Breaks: Chainsaw operation can be physically and mentally demanding. Take frequent breaks to avoid fatigue.
• Never Work Alone: Whenever possible, work with a partner who can assist you in case of an emergency.
• Know Your Limits: Don’t attempt to fell trees that are too large or too difficult for your skill level.

Strategic Insights: Safety is not just a matter of following rules; it’s a mindset. Cultivate a culture of safety by prioritizing safety in all aspects of your wood processing operations. This includes providing proper training, enforcing safety rules, and creating a work environment where employees feel comfortable reporting hazards and concerns.

Beyond the Basics: Advanced Techniques and Considerations

Once you’ve mastered the basics of chainsaw operation and maintenance, you can explore more advanced techniques and considerations to further improve your efficiency and productivity.

Bucking Techniques for Efficient Firewood Production

Bucking is the process of cutting logs into shorter lengths for firewood. Here are a few techniques to optimize your bucking process:

• Support the Log: When bucking logs, it’s important to support them to prevent the chain from pinching. Use a log jack or a bucking sawhorse to elevate the log off the ground.
• Use the Correct Cutting Technique:
  • Overbucking: Cutting from the top down. This is best for logs that are supported at both ends.
  • Underbucking: Cutting from the bottom up. This is best for logs that are supported at one end.
  • Boring Cut: Plunging the saw into the log to create a pocket. This is useful for relieving tension and preventing pinching.
• Cut to the Right Length: Cut your firewood to the appropriate length for your fireplace or wood stove. A common length is 16 inches, but you may need to adjust this depending on the size of your appliance.
• Stack Firewood Properly: Stack your firewood in a well-ventilated area to allow it to dry properly. A good stacking method is to create rows of firewood that are slightly angled to allow for air circulation.

Debarking Logs for Improved Drying

Debarking logs can significantly speed up the drying process and reduce the risk of insect infestation. Here are a few methods for debarking logs:

• Manual Debarking: Use a drawknife or a spud to remove the bark by hand. This is a labor-intensive process, but it’s effective for small quantities of logs.
• Mechanical Debarking: Use a log debarker machine to remove the bark. This is a more efficient process for large quantities of logs.
• Peeling Season: Some species of trees are easier to debark during certain times of the year when the sap is flowing. This is known as the peeling season.

Wood Splitting: Manual vs. Hydraulic

Splitting firewood can be a time-consuming and physically demanding task. There are two main methods for splitting firewood: manual splitting and hydraulic splitting.

• Manual Splitting: Use an axe or a maul to split the wood by hand. This is a good option for small quantities of firewood or for those who enjoy the physical challenge.
• Hydraulic Splitting: Use a hydraulic log splitter to split the wood. This is a much more efficient option for large quantities of firewood. Hydraulic log splitters can be either gas-powered or electric-powered.

Cost Analysis: While a hydraulic log splitter represents a significant upfront investment (ranging from $1,000 to $3,000), it can significantly reduce the time and effort required to split firewood. For example, splitting a cord of wood manually might take 8-12 hours, while splitting it with a hydraulic splitter might take only 2-4 hours. Over time, the savings in time and labor can offset the initial cost of the splitter.

Drying Firewood: Achieving Optimal Moisture Content

Green wood contains a high amount of moisture, which makes it difficult to burn and produces a lot of smoke. Seasoned wood, on the other hand, has a lower moisture content and burns more efficiently.

• Green Wood: Wood that has been freshly cut and contains a high amount of moisture.
• Seasoned Wood: Wood that has been dried for a period of time and has a lower moisture content.

The ideal moisture content for firewood is between 15% and 20%. To achieve this, you need to dry your firewood for a period of time, typically 6-12 months.

• Stack Firewood Properly: Stack your firewood in a well-ventilated area to allow for air circulation.
• Elevate Firewood Off the Ground: Elevate your firewood off the ground to prevent moisture from wicking up from the soil.
• Cover Firewood (Optional): You can cover your firewood with a tarp to protect it from rain and snow, but make sure to leave the sides open to allow for air circulation.
• Use a Moisture Meter: Use a moisture meter to check the moisture content of your firewood.

Drying Times by Wood Type: Different types of wood dry at different rates. Softwoods, such as pine and fir, dry more quickly than hardwoods, such as oak and maple. Here’s a general guideline for drying times:

• Softwoods: 6-9 months
• Hardwoods: 9-12 months
