How to Use a Stihl Chainsaw (Pro Tips for Wood Processing)

Let’s dive into the world of Stihl chainsaw operation and wood processing, focusing on professional techniques and safety.

Taming the Roar: Noise Reduction and Chainsaw Operation

One of the first things I learned when I started working with chainsaws was the importance of hearing protection. The constant roar of a chainsaw can take a serious toll on your ears. I remember one time, early in my career, I neglected to wear earplugs during a long day of felling trees. By evening, I had a persistent ringing in my ears that lasted for days. That experience taught me a valuable lesson: protecting your hearing is non-negotiable.

Chainsaws typically produce noise levels between 100 and 120 decibels (dB). Prolonged exposure to noise levels above 85 dB can cause permanent hearing damage. Earplugs, which can reduce noise by 20-30 dB, or earmuffs, which offer similar protection, are essential. Some high-end earmuffs even incorporate noise-canceling technology, which can make a significant difference during extended use.

Beyond hearing protection, minimizing noise also benefits your neighbors and the environment. Consider using newer chainsaw models that incorporate noise-reducing features, such as optimized engine designs and exhaust systems. Regular maintenance, like ensuring the chain is sharp and the engine is properly tuned, can also help reduce noise output.

Takeaway

Always prioritize hearing protection when operating a chainsaw. Consider noise-reducing chainsaw models and regular maintenance to minimize noise pollution.

Before you even start your chainsaw, take the time to assess the tree and its surroundings. Look for any hazards, such as power lines, buildings, or other trees that could be damaged if the tree falls in the wrong direction. Consider the tree’s lean, wind direction, and any branches that could affect its fall.

Notches and Back Cuts

The key to felling a tree safely and predictably is to use a combination of notches and back cuts.

1. Notch: Cut a notch on the side of the tree in the direction you want it to fall. The notch should be about one-third of the tree’s diameter and angled at 45 degrees.
2. Back Cut: Make a back cut on the opposite side of the tree, slightly above the bottom of the notch. Leave a hinge of wood between the back cut and the notch to control the tree’s fall.
3. Felling Wedges: As you make the back cut, insert felling wedges into the cut to help guide the tree’s fall and prevent the chainsaw from getting pinched.

Felling the Tree

Once you’ve made the notch and back cut, the tree should start to fall in the direction of the notch. If the tree doesn’t fall on its own, use a felling lever or wedges to help push it over.

Takeaway

Felling trees requires careful planning and precise cutting techniques. Always assess the tree and its surroundings before starting, and use a combination of notches and back cuts to control the tree’s fall.

Limbing and Bucking: Processing the Fallen Tree

Once the tree is on the ground, the next step is to limb and buck it. Limbing involves removing the branches from the trunk, while bucking involves cutting the trunk into shorter, more manageable lengths.

Limbing

When limbing, work from the base of the tree towards the top, removing the branches as you go. Use a sawing motion to cut through the branches, and be careful not to cut into the trunk.

Bucking

When bucking, consider the intended use of the wood. If you’re cutting firewood, buck the trunk into lengths that are appropriate for your stove or fireplace. If you’re cutting lumber, buck the trunk into lengths that are suitable for milling.
