I’ve been using chainsaws for many years to tackle various cutting jobs around my property. As a landowner and hobbyist chainsaw user, having the right tools makes all the difference when it comes to efficiency, safety, and getting the job done right. While chainsaws are incredibly versatile and powerful, they can also expose operators to high levels of vibration during prolonged use. This is where anti-vibration systems come into play. In this post, I’ll explore the benefits of using a chainsaw equipped with an anti-vibration system, how these systems work, and other important chainsaw technologies and safety features.
Chainsaws are one of the most useful tools for cutting and trimming trees, logs, and brush. However, operating a chainsaw exposes users to high vibration levels which can lead to fatigue, reduced control, and safety risks. Chainsaws with effective anti-vibration systems can dramatically reduce vibration exposure and improve comfort, precision, and security during use.
What are the benefits of using a chainsaw with an anti-vibration system?
Using a chainsaw with an anti-vibration system offers several benefits, including reduced fatigue, increased comfort, enhanced precision, and improved safety.
Reduced fatigue and increased comfort
One of the biggest perks of using a chainsaw with an anti-vibration system is significantly decreased operator fatigue. The vibrations generated by a chainsaw engine and cutting chain can really take a toll on your hands, arms, and body over time. This leads to discomfort, pain, and early onset of fatigue. By effectively damping vibrations with rubber isolators and ergonomic handles, an advanced anti-vibration system allows you to operate the saw for longer periods with less discomfort. Your hands and arms will thank you at the end of the day!
Related to reduced fatigue is improved comfort. Chainsaws equipped with anti-vibration technologies simply feel better to use. Rather than having constant vibrations transferred directly into your hands, the vibrations dissipate before reaching your body. This increased comfort means you can better concentrate on the cutting task at hand rather than focusing on the unpleasant sensations from the saw.
Reduced risk of developing hand-arm vibration syndrome (HAVS)
Prolonged exposure to chainsaw vibrations pose a real risk of developing hand-arm vibration syndrome (HAVS) for frequent users. This disorder is characterized by circulatory damage and nerve sensitization. Anti-vibration systems act as a safeguard against developing HAVS by significantly decreasing vibration levels. Look for modern chainsaws that advertise acceleration levels at or below 5 m/s2. This can reduce HAVS risks by a wide margin.
Enhanced precision and control
Another benefit of advanced anti-vibration systems is improved handling and precision when operating the chainsaw. Having your hands and arms constantly shaken by vibrations understandably reduces finesse and accuracy. Chainsaws equipped with anti-vibration handles and isolators give you superior control over the blade. This lets you make more exact, controlled cuts safely. Combined with refined features like tool-less chain tensioning, this results in a more precise, ergonomic cutting experience.
Using a chainsaw with effective vibration reduction inherently improves safety by reducing fatigue and increasing control as discussed above. But anti-vibration systems also contribute to safety by allowing you to keep a better, more secure grip on the chainsaw handles. With vibrations dampened, you can grasp the handles firmly without your hands being numbed or shaken loose over time. This gives you better command over the saw for safer operation. The reduction in fatigue also helps you stay alert and focused on safety.
History of anti-vibration systems in chainsaws
Anti-vibration systems have been around for over 50 years, continually improving chainsaw comfort, ergonomics, and safety. Let’s look at some of the key events in the development of anti-vibration technology in chainsaws.
The invention of the anti-vibration system
It was German power tool manufacturer STIHL that first developed anti-vibration systems for chainsaws. In 1964, STIHL filed a patent for an “Anti-vibrations-handle for portable power tool.” This revolutionary system isolated the saw handles from the engine using rubber cushioning elements. By damping vibrations originating in the engine and cutting chain before they reached the operator’s hands, it greatly reduced vibration exposure.
Evolution of anti-vibration systems
STIHL introduced the first production chainsaw equipped with its anti-vibration system in 1967 – the 041 model. Since then, chainsaw manufacturers have continuously improved and refined anti-vibration technologies. As the systems evolved from simple rubber pads to multi-point isolation with precision mounting, vibration levels dropped dramatically. Today’s chainsaws with the most advanced anti-vibration systems achieve acceleration as low as 3.5 m/s2 – a huge improvement from over 15 m/s2 in saws from the 1960s and 70s. This evolution has made modern saws far more comfortable and ergonomic for the user.
How do anti-vibration systems work?
Now that we’ve covered the history and benefits, let’s examine what’s actually inside an anti-vibration system on a modern chainsaw and how it works to dissipate vibrations.
Components of an anti-vibration system
At the heart of any anti-vibration system are rubber isolator elements that essentially suspend the saw’s handles away from the vibrating engine body. By introducing an isolating rubber barrier, vibrations from the engine and cutting chain are dampened before reaching the operator’s hands. The isolators are positioned at strategic points between the handles and engine housing. Multi-point mounting systems provide the best isolation compared to simpler single point mounts.
Vibration reduction in action
When the chainsaw engine fires up and the chain starts rotating, vibrations are generated. Without an anti-vibration system, these vibrations transfer directly into the operator’s hands. But with isolated handles, the rubber absorbers flex and dissipate the engine vibrations before they can reach the operator.
The latest anti-vibration technologies like STIHL’s “M-Tronic” system combine electronic engine management with finely tuned multi-point vibration damping to achieve extremely low vibration levels under 3.5 m/s2. Advanced low-profile saw chains also help reduce kickback vibrations for smoother cutting.
Comparing battery-powered and combustion-driven chainsaws
Battery-powered cordless chainsaws have risen in popularity in recent years as the technology has improved. They provide some notable benefits compared to traditional gas chainsaws when it comes to vibration exposure. Let’s examine those differences.
Vibration exposure reduction
Multiple studies have shown that battery-powered electric chainsaws significantly reduce vibration levels compared to gasoline-powered models. Researchers found users were exposed to over 45% less daily vibration using a cordless saw compared to a gas saw when cutting identical material.
In addition to lower vibration, cordless saws also reduce noise exposure for the user. Gas saws produce over 20 times more sound power than battery models. The lower noise levels contribute to decreased operator fatigue as well.
While battery saws do provide tangible vibration reduction benefits, proper precautions should still be taken. Safety experts recommend wearing hearing protection and anti-vibration gloves when operating any type of chainsaw for extended periods. Cordless chainsaws also offer additional ergonomic benefits like precise electronic control of the engine speed. However, gas chainsaws remain superior for heavy duty use in terms of power.
Chainsaw safety features
Let’s switch gears and run through some of the key safety technologies integrated into modern chainsaws. While anti-vibration is an important comfort and control feature, dedicated safety systems also play a huge role in reducing risks.
One of the most crucial safety mechanisms is the chain brake, which became widespread on chainsaws in the 1970s and 1980s. This system stops the chain rotation instantly if kickback is detected. Before chain brakes, frequent kickback accidents resulted in severe injuries to chainsaw operators. Studies showed kickback-related accidents dropped as much as 77% thanks to mandatory chain brakes on newer saws.
Other safety features
In addition to chain brakes, other safety features may include:
- Spark arrestor screen to reduce risk of igniting a fire
- Standard warning labels communicating kickback dangers
- Chain catcher to stop broken chains from whipping back at the user
- Front hand guard for protecting the hand on the front handle
- Automatic fast-stopping chain if kickback occurs
Following safety protocols like wearing chainsaw chaps and other protective equipment is equally important when operating a chainsaw. But integrated technologies like chain brakes and anti-vibration systems make a saw inherently safer right out of the box.
After covering the history, operation, benefits and safety features related to chainsaws with anti-vibration systems, it’s clear these technologies offer tangible advantages. While no substitute for safe operating practices, anti-vibration handles and isolators have evolved to make modern chainsaws more comfortable, ergonomic and safer to use.
The reduction in vibration exposure can lessen fatigue, improve control, and protect users from long term health risks like HAVS. Cordless electric models take vibration reduction even further. For anyone using a chainsaw extensively, selecting a model with an advanced anti-vibration system seems well worth the investment.
