How to attach a long bar to your chainsaws: 2 Easy ways

When determining whether you can attach a long bar to your chainsaw, there are two key ways of checking if it’s possible:

  1. Chainsaw engine power
  2. The manufacturer’s manual

1. Chainsaw Engine Power: Bar Length to Engine Size

Every chainsaw needs a specific amount of power, which varies according to the power source. The saw’s manufacturer determines the engine power needed to use a desired bar length. Chainsaw power is expressed in cubic centimetres (cc), and the length of a chainsaw bar is measured in inches.

A chainsaw’s power is expressed in the following units depending on its power source:

  • Gas-powered chainsaws: CC (Cubic Meter)
  • Battery-powered chainsaws: Volts
  • Electric chainsaws: Amps

CC means the bigger the number, the more powerful the engine.

Voltage means the lower the voltage, the more current to produce to get there e.g,. You can make a 36V chainsaw with the same power as a 56V model.

Amps mean the larger the number, the more power on the chainsaw.

According to, below is the power to cc chart, but it is preferable to check the manufacturer instructions as well:

Chainsaw Bar Length vs. cc Chart

Electric13-15 Amps14 – 18 Inches
Battery18-20 Volts10 – 12 Inches
Battery36-40 Volts10 – 16 Inches
Battery54-60 Volts14 – 16 Inches

2. Checking Your Chainsaw Manufacturer’s Manual

Another way of determining whether you can attach a longer bar to your chainsaw is by consulting the manufacturer’s manual. Most chainsaw manufacturers provide detailed instructions for using different types and sizes of bars on their saws. It’s always best to check the manufacturer’s instructions before purchasing or installing a bar to ensure it is compatible with your saw. Always consult the manufacturer’s guidelines to ensure compatibility. Check the guide on devices; if physically not available.

  1. Google “[Chainsaw Name] Users Manual” to find the chainsaw’s user manual.
  2. Use “CTRL + F” (or “CMD + F” on Mac) to Search for Bar Length.
  3. Find the Different Recommended Chainsaw Bars.

Advantages of Using a Longer Bar on Your Chainsaw

Using a longer bar on your chainsaw can have several advantages, primarily if you often work on large projects or deal with big trees. Here are some benefits to consider:

  1. Increased Reach: A longer bar gives you more reach, making it easier to cut high branches without needing a ladder or other lifting equipment.
  2. Improved Leverage: A long bar provides more leverage, making guiding the chainsaw through the wood easier. This can lead to smoother, more efficient cuts.
  3. Greater Versatility: With a longer bar, your chainsaw becomes more versatile, capable of tackling larger trees or logs that a shorter bar might struggle with.
  4. Enhanced Safety: A long bar can improve safety by enabling you to maintain a safe distance while cutting large logs or high branches.

However, it’s important to remember that a longer bar requires more power to operate effectively and is generally heavier. Always ensure you’re comfortable handling the additional weight and that your chainsaw’s engine can handle the increased demand.

Disadvantages of Using a Longer Bar on Your Chainsaw

Although the advantages of using a longer bar on your chainsaw can be quite significant, there are also some potential drawbacks to consider. Here are a few:

  1. More Power Required: A longer bar requires more power from the chainsaw’s engine to operate efficiently. If your engine needs to be bigger, you may experience decreased performance.
  2. Reduced Durability: A longer bar is more prone to damage due to its increased size and weight. This can lead to decreased durability and, in some cases, necessitate frequent repairs or replacements.
  3. Increased Risk of Kickback: Longer bars are more susceptible to kickback, which can be a serious safety risk when using a chainsaw. It’s important always to be aware of the potential for a kickback when using a longer bar.

How to Maintain a Chainsaw with a Longer Bar

A longer bar on your chainsaw can strain the engine, chain and other components more. To ensure it remains in top condition, it’s important to take care of your chainsaw and follow the manufacturer’s instructions for maintenance. Here are some tips for maintaining a chainsaw with a long bar:

  • Clean the chainsaw regularly to prevent the build-up of dirt, debris and sap, which can interfere with its performance.
  • Sharpen the chain often to ensure it cuts efficiently.
  • Check for wear and tear on components regularly and replace worn-out or broken parts as soon as possible.
  • Lubricate the chain every few hours while in use to keep it running smoothly.
  • Inspect chain tension regularly to keep it at optimal tension for clear and efficient cutting.
  • Balance the bar often, as an unevenly balanced bar can cause vibration and deteriorate your chainsaw’s performance.
  • Replace your saw’s sprocket whenever necessary, as improper sprockets can significantly reduce a chainsaw’s performance.

Safety Precautions When Installing a Longer Bar

Installing a longer bar on your chainsaw isn’t a task to be taken lightly; it requires precision and adherence to safety guidelines. Here are some precautions to keep in mind:

  1. Read the Manual: Always refer to your chainsaw’s manual before installing a longer bar to understand the manufacturer’s recommended instructions and safety guidelines.
  2. Proper Tools: Use the right tools when replacing the bar. Incorrect tools can lead to improper installation, causing safety risks.
  3. Chain Tension: After installing the new bar, the chainsaw chain’s tension is correct. An overly tight or loose chain can lead to accidents.
  4. Test Run: Do a test run in a safe environment before starting your work to ensure the new bar runs smoothly and correctly.
  5. Protective Gear: Always wear appropriate safety gear, including gloves, safety glasses, sturdy footwear, and a hard hat, when operating a chainsaw.
  6. Maintenance: Regularly inspect and maintain your chainsaw to ensure its efficient and safe operation. Regular maintenance includes cleaning, sharpening, and lubricating.
  7. Training: If you’re new to using a chainsaw or have installed a significantly longer bar than usual, take a chainsaw safety course to learn safe operation practices.
