Understanding Chainsaw Kickback and How to Prevent It

What is Chainsaw kickback

Chainsaw kickback can be a scary and dangerous phenomenon for any chainsaw user. As someone who regularly uses a chainsaw to cut and clear trees on my property, I know firsthand how important it is to understand what causes kickback and how to prevent it. In this blog post, I’ll explain what exactly chainsaw kickback is, what causes it, and most importantly—how you can prevent it with proper handling, safety features, and regular maintenance.

Whether you’re an experienced chainsaw operator or are planning to use one for the first time, you’ll finish this post with a solid understanding of an issue that all chainsaw users need to be aware of.

What is Chainsaw Kickback? Exploring the Question in 2024

Kickback is the sudden reactive force that occurs when the moving chain near the upper quadrant of the chainsaw bar tip contacts an object like wood or another solid surface. This contact causes the energy of the chain to suddenly be redirected in the opposite direction, forcing the guide bar to swiftly jerk back toward the operator. Kickback is extremely dangerous because it happens so quickly that the operator can be hit by the guide bar before having time to react. This can cause severe laceration injuries or even death. 

Rotational kickback is one of the most common types and occurs when the chain’s cutters grab or pinch in the wood toward the upper portion of the bar. This rotational energy gets redirected back toward the operator. Pinch kickback is similar, but happens specifically when the wood closes down and pinches the chain in the cut along the top of the guide bar. Whether rotational or pinch kickback, the safety risks come from the lightning-fast reverse reaction and moving chain. Knowing what causes kickback is the first step toward preventing it.

How to Prevent Chainsaw Kickback?

While kickback is a hazard inherent to chainsaw use, there are ways you can significantly reduce the risks through proper handling techniques, utilizing safety features, and regular saw maintenance. Here are some tips for how to operate your chainsaw safely.

Proper Chainsaw Handling

Simply being aware of kickback causes is the best place to start. But to really minimize risks, follow these proper chainsaw handling techniques:

  • Maintain a firm and steady grip with your right hand on the rear handle and your left hand on the front handle when cutting. This balanced stance gives you the most control.
  • Keep your left arm straight with your left hand wrapped firmly around the front handlebar. Don’t let go!
  • Stand with your body to the left of the chainsaw to avoid kickback injuries.
  • Don’t overreach or cut above shoulder height where you don’t have good control.
  • Maintain proper chain tension and depth gauges. This keeps the chain feed smooth and steady through the wood.
  • Release the throttle as soon as the cut is complete to avoid accidental contact at full speed.

Following these simple handling rules will give you much more control over an active chainsaw and reduce unexpected reactive forces.

Using Safety Features

Many chainsaws now come equipped with helpful safety features designed to reduce kickback. Here are some to look for:

  • Chain brakes immediately stop the chain momentum if kickback is detected. This is one of the most important safety mechanisms.
  • Reduced kickback bars and low kickback chains are designed to reduce the amount of energy transfer if contact occurs. Definitely use these when possible.
  • Tip guards provide an extra barrier of protection between your hands and the spinning chain if kickback were to occur.
  • Mitten guards on the left hand help protect vulnerable fingers.
  • Safety handles reduce the risk of your hands slipping.

I highly recommend using as many of these safety mechanisms as possible. While the odds of kickback may be low, these features act as your last line of defense if an accident does occur unexpectedly.

Regular Chainsaw Maintenance

In addition to safe handling and kickback safety features, maintaining your chainsaw properly goes a long way in preventing issues. Follow these maintenance tips:

  • Sharpen your chain regularly since dull or loose chains are more prone to grabbing and kickback.
  • Check and maintain proper chain tension often. Loose chains feed poorly.
  • Clean the oil ports and replace the bar/chain when excessively worn. This prevents binding.
  • Check that chain brake is functioning properly before each use.
  • Clean the entire saw to remove any built up sawdust, resin, etc.

Taking the time to inspect and tune up your saw ensures everything is functioning optimally and reduces preventable issues that could lead to increased kickback risk.

Conclusion

Chainsaw kickback is no joke and being on the wrong end of it can seriously injure an unprepared user. While experienced chainsaw operators know how to mitigate the risks, it’s also something beginners need to be acutely aware of before firing up their saw. This post provided a comprehensive overview of what kickback is, what causes it, and most importantly—how you can prevent it through proper handling, safety mechanisms, and regular maintenance. 

I hope you feel better equipped to operate your chainsaw safely. Please use all recommended precautions, follow manufacturer guidelines, and don’t take unnecessary risks working with a powerful motorized tool. With increased awareness and the right safety habits, you can successfully prevent dangerous kickback and other chainsaw accidents. Work smart, be prepared, and check out these additional resources:

Frequently Asked Questions

What are some common chainsaw safety features?

Some of the most common safety features include chain brakes, reduced kickback guide bars, low kickback saw chains, chain catchers, right hand guards, anti-vibration systems, and chain tensioners. Using as many of these as possible greatly improves chainsaw safety.

How often should I perform maintenance on my chainsaw?

You should inspect your saw before each use and perform periodic maintenance like sharpening the chain every 5-8 hours of use. Additionally do a thorough cleaning and inspection of all components every 40-60 hours of use. Refer to your owner’s manual.

Can I use a chainsaw without a safety tip on the guide bar?

No, you should never operate a chainsaw without a safety tip in place. This tip is a vital protective barrier designed to prevent contact injuries from the moving chain. Operating without one poses extreme risks.

What are the signs that my chainsaw’s oiler is not functioning properly?

Signs include visible smoke or smell from friction, increased chain/bar temperature, rattling chain, buildup of sawdust residue, reduced cutting performance, and exposed metal along the bar.

How can I check if my chainsaw’s oil pump is working?

Remove the bar/chain and activate the saw. The oil output can be tested by running the pump and watching for steady oil flow from the outlet port. No flow indicates pump failure.

What should I do if my chainsaw’s oil tank is empty?

Immediately stop cutting, refill with proper bar and chain oil, allow time for oil to fully distribute along the bar, and check that the oil flow returns to normal before resuming operation.

Are there any alternatives to chainsaw bar oil?

No, only use high-quality bar and chain oil designed for chainsaw lubrication. Motor oil and other substitutes do not have the same adhesive qualities and lead to insufficient lubrication.
