Stihl MS661C Chainsaw Tips for Firewood Prep: 7 Pro Hacks

The Stihl MS661C is a beast of a chainsaw. It’s designed for professional logging and forestry work, but it’s also an excellent choice for serious firewood preparation, especially if you’re dealing with large-diameter logs. However, its power demands respect and a good understanding of safe and efficient techniques. These seven hacks will help you get the most out of your MS661C while minimizing strain on yourself and the saw.

Hack 1: Mastering the Art of Felling – Precision and Safety First

Felling, or cutting down a tree, is the crucial first step in firewood preparation. It’s also the most dangerous. Before you even think about firing up your MS661C, you need to assess the tree, the surrounding area, and the weather conditions.

Assessing the Tree: Look for any signs of decay, leaning, or broken limbs. These factors will influence the direction the tree is likely to fall.
Planning the Fall: Choose a clear path for the tree to fall, free from obstacles like other trees, power lines, or buildings. Consider the natural lean of the tree and the wind direction.
Creating an Escape Route: Plan two escape routes at a 45-degree angle away from the anticipated direction of the fall. Clear these paths of any obstacles.
The Notch (or Face Cut): This is a wedge-shaped cut made on the side of the tree facing the direction you want it to fall. The notch should be about 1/3 of the tree’s diameter. I prefer a conventional notch, where the top cut is angled down at approximately 45 degrees, and the bottom cut is horizontal. This creates a clean, predictable hinge.
The Back Cut: This cut is made on the opposite side of the tree from the notch, slightly above the bottom of the notch. Never cut completely through the tree. Leave a hinge of wood, typically about 10% of the tree’s diameter. This hinge will guide the tree’s fall.
Using Felling Wedges: For larger trees, or when the tree is leaning in the wrong direction, use felling wedges to help push the tree over. Insert the wedges into the back cut before it’s completed.
The Push: As you complete the back cut (or drive in the wedges), the tree should begin to fall. Shout a warning (“Timber!”) to alert anyone in the area. Move quickly and safely along your pre-planned escape route.

A Personal Experience: I once underestimated the lean of a tree and almost had it fall in the wrong direction. Luckily, I had felling wedges in place, and they helped correct the fall. This experience taught me the importance of meticulous planning and never taking shortcuts when felling.

Data and Insights: Studies by forestry organizations show that improper felling techniques are a leading cause of logging accidents. Proper training and adherence to safety protocols can significantly reduce the risk of injury.

Measurements and Specifications:

Notch Depth: Approximately 1/3 of the tree’s diameter.
Hinge Thickness: Approximately 10% of the tree’s diameter.
Escape Route Angle: 45 degrees away from the anticipated direction of the fall.

Hack 2: Bucking Like a Pro – Optimizing Cuts for Firewood Size

Bucking is the process of cutting the felled tree into manageable lengths for firewood. The Stihl MS661C’s power makes this task relatively easy, but it’s still important to use efficient techniques to minimize effort and maximize wood yield.

Planning Your Cuts: Before you start cutting, plan where you want to make your cuts. Consider the size of your wood stove or fireplace. Standard firewood lengths are 16 inches, but this can vary depending on your needs.
Supporting the Log: Ensure the log is properly supported to prevent pinching the saw blade. Use log supports, sawhorses, or smaller logs to elevate the log.
The Bore Cut (for Large Logs): For very large logs, I often use a bore cut. This involves plunging the tip of the chainsaw bar into the log to create a cut from the inside out. This helps relieve tension and prevent the bar from getting pinched. However, bore cuts are inherently more dangerous and require advanced chainsaw skills. Always use extreme caution and ensure you have a solid stance.
Cutting Techniques: Use a smooth, controlled motion when cutting. Let the saw do the work. Avoid forcing the saw, as this can lead to kickback.
Dealing with Tension: Be aware of tension and compression in the log. If the log is supported at both ends, the top will be in tension, and the bottom will be in compression. To avoid pinching, cut the top first. If the log is supported in the middle, the top will be in compression, and the bottom will be in tension. Cut the bottom first.
Using a Measuring Tool: Use a measuring stick or tape measure to ensure consistent firewood lengths. This will make stacking and burning the wood much easier.

A Case Study: I once had a large oak log that was severely compressed on the bottom. I tried cutting it from the top, and the bar got pinched almost immediately. After switching to cutting from the bottom first, the cut went smoothly. This experience highlighted the importance of understanding tension and compression in logs.

Data and Insights: Studies have shown that using proper bucking techniques can increase firewood yield by up to 15%. This is because it minimizes waste and ensures that the wood is cut to the optimal length for burning.

Measurements and Specifications:

Standard Firewood Length: 16 inches (adjustable based on your stove/fireplace).
Log Support Height: Varies depending on the log size and your comfort level. Aim for a height that allows you to maintain a good posture.

Hack 3: The Hydraulic Splitter Advantage – Speed and Efficiency

Splitting wood by hand with an axe is a time-honored tradition, but it’s also physically demanding and inefficient, especially when dealing with large quantities of wood. A hydraulic log splitter can dramatically increase your speed and efficiency.

Choosing the Right Splitter: Hydraulic log splitters come in various sizes and tonnage ratings. For most firewood preparation, a 20-30 ton splitter is sufficient. Consider the size of the logs you typically split and choose a splitter that can handle them.
Safety First: Always wear safety glasses and gloves when operating a log splitter. Keep your hands and feet clear of the splitting wedge.
Positioning the Log: Place the log squarely on the splitter bed, ensuring it’s stable and won’t roll.
Splitting Technique: Engage the splitter lever and allow the wedge to split the log. If the log doesn’t split on the first attempt, reposition it and try again.
Splitting Large Rounds: For very large rounds, I often split them into quarters or smaller pieces before attempting to split them into firewood-sized pieces. This reduces the strain on the splitter and makes the process safer.
Dealing with Knotty Wood: Knotty wood can be difficult to split. Try splitting the log along the grain, avoiding the knots if possible. Sometimes, it’s necessary to use a sledgehammer and splitting wedge to break apart knotty pieces.

A Personal Experience: I used to split all my firewood by hand. It was exhausting and time-consuming. After investing in a hydraulic log splitter, I was able to process the same amount of wood in a fraction of the time, with significantly less effort.

Data and Insights: Studies have shown that using a hydraulic log splitter can increase firewood splitting efficiency by up to 80% compared to splitting by hand. This translates to significant time and energy savings.

Measurements and Specifications:

Hydraulic Log Splitter Tonnage: 20-30 tons (typical for firewood preparation).
Log Splitter Bed Length: Varies depending on the model. Choose a bed length that can accommodate the longest logs you typically split.
