Power and Performance: Real-World Testing
I’ve put the CS680 through its paces in various scenarios, from felling standing timber to processing downed trees into firewood. Here’s what I’ve found:
- Felling: The CS680 handles trees up to 24 inches in diameter with ease. I’ve used it to fell oak, maple, and pine, and it consistently delivered clean, controlled cuts. The decompression valve makes starting the saw much easier, especially when it’s cold.
- Bucking: This is where the CS680 truly shines. The powerful engine and sharp chain make quick work of bucking logs into manageable lengths. I’ve processed entire cords of wood in a single day without feeling overly fatigued.
- Limbing: While the CS680 is powerful, it can be a bit unwieldy for delicate limbing tasks. The weight and size make it less maneuverable than smaller chainsaws. However, with practice and careful technique, it can still be used effectively for limbing larger branches.
Personal Story: I remember one particularly challenging day when I was clearing a heavily wooded area after a storm. Fallen trees were everywhere, tangled together like a giant’s spilled pick-up-sticks. The CS680 was my workhorse that day. Its power allowed me to cut through thick trunks and tangled branches, turning chaos into order. It was a testament to its reliability and performance under pressure.
Fuel and Oil: The Lifeblood of Your Chainsaw
Proper fuel and oil mixtures are essential for the longevity and performance of your chainsaw. The Echo CS680 requires a 50:1 fuel-to-oil ratio. This means mixing 50 parts of gasoline with 1 part of 2-stroke engine oil.
- Fuel: Use high-quality gasoline with a minimum octane rating of 89. Avoid using gasoline that contains ethanol, as it can damage the engine. If you must use gasoline with ethanol, make sure it doesn’t exceed 10%.
- Oil: Use a high-quality 2-stroke engine oil specifically designed for air-cooled engines. Echo Power Blend X oil is a good option, but other reputable brands will work as well.
- Mixing: Always mix the fuel and oil in a separate container. Pour the correct amount of oil into the container first, then add the gasoline. Shake the container thoroughly to ensure proper mixing.
Data Point: Using the wrong fuel-to-oil ratio can significantly reduce the lifespan of your chainsaw engine. A lean mixture (too little oil) can lead to excessive wear and tear, while a rich mixture (too much oil) can cause carbon buildup and reduced performance. I have seen many people ignore this and end up with damaged cylinders and pistons.
Pro Tip: I always mix a small batch of fuel at a time, enough for a day or two of work. This helps to ensure that the fuel is fresh and prevents the oil from separating. I also use a fuel stabilizer to extend the shelf life of the fuel, especially during periods of inactivity.
Chain and Bar: Choosing the Right Combination
The chain and bar are critical components of your chainsaw, and selecting the right combination can significantly impact performance and safety. The Echo CS680 can accommodate bar lengths ranging from 18″ to 27″.
- Bar Length: The appropriate bar length depends on the size of the trees you’ll be cutting. A shorter bar (18″-20″) is suitable for smaller trees and limbing, while a longer bar (24″-27″) is better for felling larger trees.
- Chain Type: There are several types of chainsaw chains available, each designed for specific applications.
- Full Chisel: These chains have aggressive cutting teeth and are ideal for fast cutting in clean wood.
- Semi-Chisel: These chains have slightly less aggressive teeth but are more durable and forgiving in dirty or frozen wood.
- Low-Kickback: These chains are designed to reduce the risk of kickback and are a good choice for beginners.
- Chain Maintenance: Proper chain maintenance is essential for safe and efficient cutting. Keep the chain sharp by filing the teeth regularly. Check the chain tension frequently and adjust as needed. Lubricate the chain with bar and chain oil to reduce friction and wear.
Technical Requirement: Chain tension should be checked before each use and adjusted as needed. A properly tensioned chain should be snug against the bar but still able to be pulled around by hand. Overtightening the chain can cause excessive wear on the bar and chain, while undertightening can lead to chain derailment.
Case Study: I once worked on a project where we were felling large oak trees. We started with a full chisel chain, which cut through the wood quickly but dulled easily in the dirty conditions. We switched to a semi-chisel chain, which was more durable and held its edge longer. This simple change significantly improved our efficiency and reduced downtime.
Starting and Operating the CS680: A Step-by-Step Guide
Starting and operating a chainsaw safely requires following a specific procedure. Here’s a step-by-step guide for the Echo CS680:
- Safety Check: Before starting the chainsaw, inspect it for any damage or loose parts. Check the fuel and oil levels, and ensure the chain is properly tensioned and lubricated.
- Starting Position: Place the chainsaw on a flat, stable surface. Make sure the chain is not touching anything.
- Choke: If the engine is cold, engage the choke. If the engine is warm, leave the choke off.
- Decompression Valve: Press the decompression valve to release pressure in the cylinder. This will make it easier to pull the starter cord.
- Starting: Grasp the starter handle firmly and pull it sharply until the engine starts. You may need to pull the starter cord several times, especially when the engine is cold.
- Warm-Up: Allow the engine to warm up for a few minutes before using the chainsaw.
- Operating: Hold the chainsaw firmly with both hands. Keep your feet firmly planted and maintain a stable stance.
- Cutting: Use smooth, controlled movements when cutting. Avoid forcing the chainsaw, as this can lead to kickback or damage to the saw.
- Stopping: To stop the chainsaw, release the throttle and press the stop switch.
Safety Codes: Always wear appropriate personal protective equipment (PPE) when operating a chainsaw, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps. Never operate a chainsaw when you are tired or under the influence of drugs or alcohol.
Safety Features: Protecting Yourself in the Woods
The Echo CS680 incorporates several safety features designed to protect the operator:
- Chain Brake: The chain brake is a critical safety device that stops the chain instantly in the event of kickback. It is activated by pushing the front hand guard forward.
- Throttle Lockout: The throttle lockout prevents accidental acceleration of the chainsaw. You must squeeze the throttle lockout lever before you can engage the throttle.
- Chain Catcher: The chain catcher prevents the chain from flying back towards the operator if it breaks or derails.
- Anti-Vibration System: The anti-vibration system reduces the amount of vibration transmitted to the operator, reducing fatigue and the risk of developing vibration-related injuries.
Practical Tips: I always check the chain brake before each use to ensure it is functioning properly. I also make sure to keep the chain catcher clean and free of debris.
Original Research: In a study I conducted with a local logging company, we found that chainsaw operators who consistently used PPE and followed safety procedures had a significantly lower risk of injury compared to those who did not. The study also showed that regular maintenance of safety features, such as the chain brake and chain catcher, was crucial for preventing accidents.

Wood Selection Criteria: Choosing the Right Wood for the Job
The type of wood you’re cutting can significantly impact the performance of your chainsaw. Different types of wood have different densities, moisture contents, and grain patterns, which can affect cutting speed, chain wear, and the overall efficiency of your work.
- Hardwoods vs. Softwoods: Hardwoods, such as oak, maple, and hickory, are denser and more difficult to cut than softwoods, such as pine, fir, and cedar. Hardwoods require a sharper chain and more power to cut efficiently.
- Moisture Content: The moisture content of wood can also affect its cutting properties. Green wood (freshly cut) is more difficult to cut than seasoned wood (dried). Green wood tends to bind on the chain, while seasoned wood cuts more cleanly.
- Grain Pattern: The grain pattern of wood can also affect cutting. Wood with a straight grain is easier to cut than wood with a twisted or knotty grain.
Material Specifications:
- Optimal Moisture Content for Firewood: 15-20%
- Average Density of Oak: 45-55 lbs/cubic foot
- Average Density of Pine: 25-35 lbs/cubic foot
Personalized Storytelling: I once spent an entire day trying to cut through a large oak log that was still green. The chain kept binding, and the saw was working overtime. I finally realized that the wood was too wet and needed to dry out before I could cut it effectively. I learned a valuable lesson that day: understanding the properties of wood is just as important as having a powerful chainsaw.
Tool Calibration Standards: Ensuring Precision and Accuracy
Proper tool calibration is essential for achieving precise and accurate cuts. This includes calibrating the chainsaw itself, as well as other tools used in wood processing, such as measuring tapes, levels, and wedges.
- Chainsaw Calibration: While chainsaws don’t have traditional calibration settings, it’s important to ensure that the chain is properly sharpened and tensioned. A dull or loose chain will not cut accurately and can be dangerous.
- Measuring Tapes: Regularly check the accuracy of your measuring tape by comparing it to a known standard. Replace the tape if it is stretched or damaged.
- Levels: Use a level to ensure that your cuts are straight and square. Check the accuracy of your level periodically by placing it on a known level surface.
- Wedges: Use wedges to prevent the tree from pinching the saw during felling. Make sure the wedges are properly sized for the tree being felled.
Technical Limitations: The accuracy of your cuts is limited by the precision of your tools and your own skill. Even with the best tools, it’s impossible to achieve perfect accuracy. However, by following proper procedures and paying attention to detail, you can minimize errors and achieve satisfactory results.
Safety Equipment Requirements: Protecting Yourself from Injury
Using the right safety equipment is essential for protecting yourself from injury when working with a chainsaw. This includes:
- Helmet: A helmet protects your head from falling branches and other debris.
- Eye Protection: Eye protection, such as safety glasses or goggles, protects your eyes from flying wood chips and sawdust.
- Hearing Protection: Hearing protection, such as earplugs or earmuffs, protects your ears from the loud noise of the chainsaw.
- Gloves: Gloves protect your hands from cuts, scratches, and blisters.
- Chainsaw Chaps: Chainsaw chaps protect your legs from chainsaw cuts.
- Steel-Toed Boots: Steel-toed boots protect your feet from falling logs and other hazards.
Industry Standards: OSHA (Occupational Safety and Health Administration) has specific requirements for the use of PPE when operating a chainsaw. These requirements vary depending on the type of work being performed.
Practical Examples: I always wear a helmet, eye protection, hearing protection, gloves, and chainsaw chaps when operating a chainsaw. I also make sure to wear steel-toed boots to protect my feet. I have seen countless accidents happen in the woods, and I know that wearing the right safety equipment can make the difference between a minor injury and a serious one.
Log Dimensions and Cord Volumes: Measuring Your Harvest
Understanding log dimensions and cord volumes is essential for accurately measuring your harvest and determining its value.
- Log Diameter: The diameter of a log is measured at the small end of the log.
- Log Length: The length of a log is measured from end to end.
- Cord Volume: A cord is a unit of volume used to measure firewood. A standard cord is 4 feet high, 4 feet wide, and 8 feet long, for a total volume of 128 cubic feet.
Precise Measurements:
- Board Foot: A board foot is a unit of volume used to measure lumber. It is equal to 144 cubic inches.
- Doyle Log Scale: The Doyle Log Scale is a formula used to estimate the number of board feet in a log.
- Scribner Log Scale: The Scribner Log Scale is another formula used to estimate the number of board feet in a log. It is generally considered to be more accurate than the Doyle Log Scale.
Data Points and Statistics: The average price of a cord of firewood varies depending on the location, type of wood, and season. In general, hardwoods are more expensive than softwoods.
Wood Drying Tolerances: Achieving Optimal Moisture Content
Achieving the optimal moisture content is crucial for producing high-quality firewood. Wood that is too wet will be difficult to burn and will produce excessive smoke. Wood that is too dry will burn too quickly and will not provide as much heat.
- Air Drying: Air drying is the most common method of drying firewood. It involves stacking the wood in a well-ventilated area and allowing it to dry naturally.
- Kiln Drying: Kiln drying is a faster method of drying firewood. It involves placing the wood in a kiln and using heat to remove the moisture.
Drying Times: The amount of time it takes to dry firewood depends on several factors, including the type of wood, the size of the pieces, and the climate. In general, hardwoods take longer to dry than softwoods.
Technical Requirements: The optimal moisture content for firewood is 15-20%. This can be measured using a moisture meter.
