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.

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.
- 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.
- 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.
- 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
