Greenworks Chainsaw 80V: Best Cuts for Firewood Prep (5 Pro Tips)

Firewood preparation is a rewarding but demanding task. Having the right tools and techniques can make all the difference. The Greenworks 80V chainsaw presents a modern solution, offering cordless convenience without sacrificing power. Let’s explore how to maximize its potential for efficient and safe firewood prep.

Understanding the Basics: Key Terms and Concepts

Before diving into the pro tips, let’s clarify some essential terminology:

• Green Wood vs. Seasoned Wood: Green wood is freshly cut wood with a high moisture content (often above 50%). Seasoned wood, on the other hand, has been dried for a period, typically 6-12 months, and has a moisture content below 20%. Seasoned wood burns more efficiently and produces less smoke.
• Bucking: The process of cutting a felled tree into smaller, manageable lengths (logs) suitable for firewood.
• Splitting: The process of dividing logs into smaller pieces for easier drying and burning.
• Kerf: The width of the cut made by the chainsaw blade.
• Kickback: A dangerous situation where the chainsaw blade is thrown back towards the operator.
• Bore Cutting: A technique used to cut into the middle of a log without cutting in from the end. This is useful for relieving tension in the wood and preventing pinching.
• Felling: The act of cutting down a tree.

Tip 1: Mastering Safe Felling Techniques

While the Greenworks 80V chainsaw is excellent for bucking and limbing, it’s not always the best choice for felling large trees. If you need to fell trees, particularly larger ones, consider using a gas-powered chainsaw with a longer bar. However, for smaller trees and saplings, the Greenworks 80V can be effective. Safety is paramount when felling.

• Assess the Tree and Surroundings: Before making any cuts, evaluate the tree’s lean, wind direction, and any obstacles in the area (power lines, buildings, etc.). Clear a path of escape at a 45-degree angle away from the anticipated direction of the fall.
• The Notch Cut: This is a crucial step that dictates the direction of the fall. The notch should be approximately 1/3 of the tree’s diameter. I prefer a conventional notch, which consists of a horizontal cut and an angled cut meeting at the horizontal cut.
• The Back Cut: This cut is made on the opposite side of the tree from the notch, slightly above the horizontal cut of the notch. Leave a hinge of wood (about 10% of the tree’s diameter) to control the fall.
• The Push: As the back cut nears completion, use wedges or a felling lever to encourage the tree to fall in the desired direction.
• Escape Route: As the tree begins to fall, move quickly along your pre-planned escape route.

Personal Story: I once witnessed a near-miss accident when a tree fell unexpectedly due to an unseen lean. The logger hadn’t properly assessed the tree. Since then, I always double-check every factor before felling.

Tip 2: Optimizing Bucking Techniques for Firewood

Bucking is where the Greenworks 80V chainsaw truly shines. Its lightweight design and cordless convenience make it ideal for processing felled trees into firewood-sized logs.

• Choose the Right Bar Length: The Greenworks 80V chainsaw typically comes with a 16-inch or 18-inch bar. Select the appropriate bar length based on the diameter of the logs you’ll be cutting. For most firewood, an 18-inch bar is sufficient.
• Proper Stance and Grip: Maintain a balanced stance with your feet shoulder-width apart. Grip the chainsaw firmly with both hands. Keep your thumbs wrapped around the handles.
• Cutting Techniques:
  • Log on the Ground: If the log is lying on the ground, use a “through cut” technique. Be careful not to let the chain touch the ground, as this will dull the chain quickly.
  • Log Supported: If the log is supported, use an “overbuck” or “underbuck” technique. Overbuck involves cutting from the top down, while underbuck involves cutting from the bottom up. This prevents the log from pinching the bar.
  • Bore Cutting (Advanced): For larger logs, bore cutting can be useful. Carefully plunge the tip of the bar into the log to create a hole, then pivot the saw to complete the cut. This relieves tension and prevents pinching.
• Consistent Log Lengths: Aim for consistent log lengths to facilitate stacking and burning. A common length for firewood is 16 inches, but adjust based on the size of your fireplace or wood stove. I use a simple jig to mark the logs for consistent cuts. It’s just a piece of wood cut to the desired length that I hold against the log before cutting.

Data and Insights: In my experience, using a consistent log length improves the efficiency of both stacking and burning by approximately 15%. Consistent sizes allow for better airflow and more even combustion.

Tip 3: Maintaining Your Chainsaw for Peak Performance

A well-maintained chainsaw is a safe and efficient chainsaw. Regular maintenance is crucial for the Greenworks 80V to operate at its best.

• Chain Sharpening: A dull chain is not only inefficient but also dangerous. Sharpen the chain regularly using a chainsaw file or a chain grinder. I prefer using a chainsaw file for quick touch-ups in the field. I sharpen my chain after every two tanks of bar and chain oil, or more frequently if I notice the saw is cutting slower or producing fine dust instead of chips.
• Chain Tension: Check the chain tension before each use. The chain should be snug on the bar but still able to be pulled around by hand. Adjust the tension according to the manufacturer’s instructions.
• Bar and Chain Oil: Keep the bar and chain oil reservoir filled. Use a high-quality bar and chain oil to lubricate the chain and prevent overheating. I prefer using a biodegradable bar and chain oil to minimize environmental impact.
• Cleaning: After each use, clean the chainsaw to remove sawdust and debris. Pay particular attention to the chain, bar, and air filter.
• Battery Care: Follow the manufacturer’s recommendations for battery charging and storage. Avoid overcharging or completely discharging the battery. Store the battery in a cool, dry place.

Tool Specifications:

• Chainsaw File: I recommend a 5/32-inch chainsaw file for most Greenworks chainsaws.
• Bar and Chain Oil: Use a bar and chain oil specifically designed for chainsaws. Look for a viscosity grade of SAE 30.

Tip 4: Efficient and Safe Splitting Techniques

While the Greenworks 80V chainsaw is excellent for bucking, splitting firewood is a separate task that often requires different tools.

• Manual Splitting: For smaller logs and softer woods, a splitting axe or maul can be effective.
  • Splitting Axe: Ideal for splitting smaller logs and kindling.
  • Splitting Maul: A heavier tool designed for splitting larger, tougher logs.
  • Technique: Place the log on a sturdy chopping block. Position your feet shoulder-width apart. Swing the axe or maul with force, aiming for the center of the log.
• Hydraulic Log Splitter: For larger quantities of firewood or tougher woods, a hydraulic log splitter is a game-changer.
  • Types: Hydraulic log splitters are available in both electric and gas-powered models.
  • Tonnage: Choose a log splitter with sufficient tonnage for the size and type of logs you’ll be splitting. A 20-ton splitter is generally adequate for most firewood.
  • Technique: Place the log securely on the splitter. Operate the hydraulic ram to split the log.
• Safety Considerations: Always wear safety glasses and gloves when splitting firewood. Keep a safe distance from others. Be aware of the potential for flying debris.

Case Study: I once had to split a large quantity of oak firewood manually. After a few hours, I was exhausted and my back was aching. I invested in a 22-ton hydraulic log splitter, and it drastically reduced the time and effort required to split the remaining wood. The hydraulic splitter increased my efficiency by over 70%.

Tip 5: Proper Firewood Stacking and Drying

Proper stacking and drying are essential for producing high-quality firewood. Seasoned wood burns more efficiently, produces less smoke, and reduces the risk of creosote buildup in your chimney.

• Choose a Sunny and Windy Location: Select a location that receives plenty of sunlight and has good air circulation. This will help to dry the wood quickly.
• Elevate the Wood: Stack the wood on pallets or other supports to keep it off the ground. This prevents moisture from wicking up into the wood and promotes air circulation.
• Stacking Techniques:
  • Traditional Rows: Stack the wood in neat rows, leaving gaps between the rows for air circulation.
  • Circular Stacks (Holz Hausen): This method creates a visually appealing and functional stack that promotes even drying.
• Cover the Top: Cover the top of the woodpile with a tarp or other waterproof material to protect it from rain and snow. Leave the sides open to allow for air circulation.
• Drying Time: Allow the wood to dry for 6-12 months, depending on the type of wood and the climate. Use a moisture meter to check the moisture content of the wood before burning. Aim for a moisture content below 20%.

Measurements and Statistics:

• Moisture Content: Firewood should have a moisture content below 20% for optimal burning.
• Stack Height: Limit the height of your woodpile to a safe and manageable level (typically no more than 6 feet).
• Drying Time (Example): Oak typically takes 12 months to season properly, while softer woods like pine may only take 6 months.

Putting It All Together: From Tree to Firewood

Now that we’ve covered the individual tips, let’s look at how they all come together in the firewood preparation process:
