Kawasaki Chainsaw Tips For Wood Processing (5 Pro Techniques)

Cleaning a chainsaw, especially a Kawasaki, is something I’ve learned to appreciate over years of felling trees and processing wood. A clean saw runs smoother, cuts more efficiently, and lasts longer. It’s a small investment of time that pays off big in the long run. Let’s dive into some pro techniques I’ve picked up specifically for Kawasaki chainsaws when processing wood.

Kawasaki Chainsaw Tips for Wood Processing (5 Pro Techniques)

Wood processing with a chainsaw is more than just cutting logs. It involves understanding your saw, the wood you’re cutting, and how to do it safely and efficiently. I’ve spent countless hours in the woods, turning raw logs into usable lumber and firewood. These are the techniques I rely on with my Kawasaki chainsaws.

1. Mastering the Felling Cut with Your Kawasaki

Felling is the foundation of wood processing. A bad felling cut can waste wood, damage your saw, or even be dangerous. I remember one time, early in my career, I misjudged the lean of a tree and nearly pinched my saw. It taught me a valuable lesson about precision and planning.

Understanding the Lean and Tension

Before you even start your saw, assess the tree. Which way is it leaning? Where is the tension in the wood? These factors dictate your cutting strategy. A tree leaning heavily in one direction requires a different approach than a perfectly upright one.

Lean Assessment: Use a plumb bob or simply sight along the trunk to determine the lean.
Tension Assessment: Look for branches pulling the tree in a particular direction. This indicates tension on that side of the trunk.

The Hinge: Your Steering Wheel

The hinge is the uncut portion of the tree that guides its fall. Its size and position are crucial. Too small, and the tree might fall unpredictably. Too large, and you risk barber-chairing (splitting up the trunk).

Hinge Size: Aim for a hinge that’s about 80% of the bar’s width.
Hinge Placement: Position the hinge so it’s perpendicular to the desired felling direction.

The Bore Cut: Avoiding Pinching

The bore cut is a technique where you plunge the tip of the saw into the tree before completing the felling cut. This is particularly useful for trees with significant lean or tension, as it helps prevent the bar from getting pinched.

How to Bore Cut: Carefully plunge the tip of the bar into the tree, keeping the saw at a low RPM until the tip is completely embedded. Then, pivot the saw to create the desired cut.
Kawasaki Chainsaw Tip: Kawasaki chainsaws often have excellent anti-vibration systems, making bore cuts more comfortable and precise.

The Felling Cut Sequence

Here’s the sequence I follow:

Notch Cut: Create a notch on the side of the tree facing the desired felling direction. The notch should be about 20% of the tree’s diameter.
Bore Cut (if needed): If the tree has significant lean or tension, use a bore cut to relieve pressure.
Felling Cut: Cut from the back of the tree towards the notch, leaving the hinge intact.
Wedges: As you cut, insert wedges into the cut to prevent the tree from leaning back and pinching the saw.

Wood Type and Its Impact

Different wood types require different approaches. Hardwoods like oak and maple are denser and require more power. Softwoods like pine and fir are easier to cut but can be more prone to splintering.

Hardwoods: Use a sharp chain and a higher RPM.
Softwoods: Be mindful of splintering and adjust your cutting angle accordingly.

Safety First

Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, and chainsaw chaps. Be aware of your surroundings and have an escape route planned.

Escape Route: Clear a path behind you at a 45-degree angle from the tree.
Spotter: If possible, have someone spot you while felling.

Takeaway: Mastering the felling cut is essential for safe and efficient wood processing. Understand the lean and tension of the tree, create a proper hinge, and use the bore cut when necessary.

2. Precision Bucking: Maximizing Yield and Minimizing Waste

Bucking is the process of cutting a felled tree into smaller, more manageable logs. It’s where you can really maximize your yield and minimize waste. I’ve seen so much wood wasted due to poor bucking techniques. It’s a shame, especially when you consider the effort that goes into felling the tree in the first place.

Understanding Log Grading

Before you start bucking, understand log grading. Different grades of logs are suitable for different purposes. Knowing this will help you decide where to make your cuts.

Grade 1 Logs: Clear, straight logs with minimal knots. These are ideal for lumber.
Grade 2 Logs: Logs with some knots and imperfections. These can be used for lower-grade lumber or firewood.
Grade 3 Logs: Logs with significant knots, rot, or other defects. These are best suited for firewood.

Optimizing Cut Lengths

The length of your logs depends on their intended use. Lumber logs are typically cut to standard lengths (e.g., 8 feet, 10 feet, 12 feet). Firewood logs are cut to the length of your firewood processor or stove.

Lumber Logs: Consider the dimensions of the lumber you want to produce.
Firewood Logs: Measure your firewood processor or stove and cut accordingly. I usually cut mine to 16 inches.

Techniques for Avoiding Pinching During Bucking

Pinching is a common problem when bucking. The weight of the log can cause the cut to close, trapping the saw. Here are a few techniques to avoid it:

Cutting from Above and Below: Cut partway through the log from above, then flip it over and finish the cut from below.
Using Wedges: Insert wedges into the cut to keep it open.
Making Relief Cuts: Make small cuts on the opposite side of the log to relieve tension.

The Importance of Sharp Chains

A dull chain is not only inefficient, but it’s also dangerous. It requires more force to cut, increasing the risk of kickback. I sharpen my chains every few hours when I’m bucking.

Chain Sharpening: Use a chainsaw file or a chain grinder to sharpen your chains.
Kawasaki Chainsaw Tip: Kawasaki chainsaws often have easily accessible chain tensioning systems, making it easy to keep your chain properly tensioned.

Bucking on Uneven Terrain

Bucking on uneven terrain can be challenging. It’s important to stabilize the log before you start cutting.

Using Support Logs: Place smaller logs under the log you’re bucking to provide support.
Using a Cant Hook: A cant hook is a tool used to roll logs. It can be helpful for positioning logs on uneven terrain.

Wood Type Considerations

Just like with felling, wood type affects bucking. Hardwoods require more power, while softwoods are more prone to splintering.

Hardwoods: Use a sharp chain and a higher RPM.
Softwoods: Be mindful of splintering and adjust your cutting angle accordingly.

Safety First

Always wear appropriate safety gear and be aware of your surroundings. Be especially careful when bucking on uneven terrain.

Footing: Make sure you have solid footing before you start cutting.
Clearance: Ensure there’s enough clearance around the log to avoid tripping or falling.

Takeaway: Precision bucking is about maximizing yield and minimizing waste. Understand log grading, optimize cut lengths, and use techniques to avoid pinching.

3. Efficient Limbing: Clearing Branches Safely

Limbing is the process of removing branches from a felled tree. It’s often the most tedious part of wood processing, but it’s also crucial for safety and efficiency. I’ve learned that a systematic approach to limbing can save a lot of time and effort.

The Importance of Proper Stance and Grip

Your stance and grip are crucial for safe and efficient limbing. You need to be stable and have good control of the saw.

Stance: Stand with your feet shoulder-width apart, with one foot slightly ahead of the other.
Grip: Grip the saw firmly with both hands, keeping your wrists straight.

Limbing Techniques: Top, Bottom, and Sides

There are different techniques for limbing, depending on the position of the branches.

Top Limbing: Limbing branches that are on top of the log.
Bottom Limbing: Limbing branches that are underneath the log.
Side Limbing: Limbing branches that are on the sides of the log.

Dealing with Tensioned Branches

Branches under tension can snap back when cut, posing a safety hazard. Here’s how to deal with them:

Make a Relief Cut: Make a small cut on the tension side of the branch before completing the cut. This will relieve the tension and prevent the branch from snapping back.
Use a Lever: Use a lever to bend the branch away from you before cutting.

Clearing Brush and Debris

As you limb, clear away brush and debris to create a safe working area.

Use a Brush Hook: A brush hook is a tool used to clear brush and small branches.
Pile Debris: Pile the debris in a designated area to keep it out of the way.

The Importance of a Sharp Chain

A sharp chain is essential for efficient limbing. A dull chain will require more force to cut, increasing the risk of kickback.

Chain Sharpening: Sharpen your chain regularly, especially when limbing.
Kawasaki Chainsaw Tip: Kawasaki chainsaws are known for their reliable oiling systems, which help keep the chain lubricated and sharp.

Wood Type Considerations

Softwoods tend to have more branches than hardwoods, making limbing more time-consuming.

Softwoods: Be prepared to spend more time limbing.
Hardwoods: Limbing is typically quicker and easier.

Safety First

Always wear appropriate safety gear and be aware of your surroundings. Be especially careful when limbing branches under tension.

Eye Protection: Wear eye protection to protect your eyes from flying debris.
Gloves: Wear gloves to protect your hands from cuts and scratches.

Takeaway: Efficient limbing is about using proper techniques, dealing with tensioned branches safely, and keeping your chain sharp.

4. Splitting Techniques for Firewood Preparation

Splitting firewood is a necessary step for many who rely on wood for heating. I’ve tried every method imaginable, from hand-splitting with a maul to using high-powered hydraulic splitters. Here are some techniques I’ve found most effective.

Hand Splitting with a Maul

Hand splitting is a great way to get some exercise and connect with the wood. However, it’s also physically demanding and requires proper technique.

Choosing the Right Maul: A heavy maul (6-8 pounds) is best for splitting large, dense logs. A lighter maul (4-6 pounds) is better for smaller logs.
Stance and Swing: Stand with your feet shoulder-width apart, with one foot slightly ahead of the other. Grip the maul firmly with both hands and swing it over your head, bringing it down on the log with force.
Targeting Splits: Aim for existing cracks or knots in the log. These are weak points that will make splitting easier.
Using Wedges: If a log is particularly difficult to split, use wedges to help break it apart.

Using a Log Splitter

A log splitter can make firewood preparation much faster and easier. There are two main types of log splitters: hydraulic and kinetic.

Hydraulic Log Splitters: These splitters use hydraulic pressure to push a log against a wedge. They are powerful and can split even the most difficult logs.
Kinetic Log Splitters: These splitters use a flywheel to generate momentum, which is then used to split the log. They are faster than hydraulic splitters but may not be as powerful.
Choosing the Right Log Splitter: Consider the size and type of logs you’ll be splitting when choosing a log splitter. A larger splitter with more tonnage is needed for larger, denser logs.

Splitting Techniques for Different Wood Types

Different wood types split differently. Some woods, like oak and ash, split easily. Others, like elm and sycamore, are notoriously difficult to split.

Easy-Splitting Woods: Oak, ash, maple, and birch.
Difficult-Splitting Woods: Elm, sycamore, sweetgum, and knotted pine.
Techniques for Difficult Woods: Use a heavier maul or a more powerful log splitter. Split the logs when they are green (freshly cut), as they are easier to split when wet.

Safety First

Splitting firewood can be dangerous. Always wear appropriate safety gear and be aware of your surroundings.

Eye Protection: Wear eye protection to protect your eyes from flying debris.
Gloves: Wear gloves to protect your hands from cuts and blisters.
Foot Protection: Wear sturdy boots to protect your feet from dropped logs.
Log Splitter Safety: Follow the manufacturer’s instructions when using a log splitter. Keep your hands and feet clear of the splitting area.

Takeaway: Splitting firewood requires proper technique and the right tools. Choose the right maul or log splitter for the job, and use techniques to split different wood types effectively.
