A chain falling off a pole saw can occur due to three reasons and one of the primary reason is improper chain tension; a chain that is too loose or tight can lead to derailment. The balance between snugness and flexibility is crucial for smooth operation and, if not maintained, can cause the chain to come off frequently.
In this blog, we will discuss the three main reasons why your pole saw chain falling off and provide solutions to address these issues.
What Causes the Pole Chainsaw Chain to Keep Coming Off the Guide Bar?
A chainsaw is a powerful tool used for various cutting and pruning tasks, but a common issue faced by users is the chain coming off the guide bar. There are several possible causes for this problem, which can be frustrating and reduce work efficiency.
One common reason of chain falling off is loose chain tension. If the chain is not properly tensioned, it can become loose during operation, leading to it slipping off the guide bar.
Another factor that contributes to this issue is wear and tear on the guide bar. Over time, the guide bar may develop uneven surfaces, burrs, or bends that prevent the chain from fitting snugly, making it more susceptible to coming off during operation.
Damages to the drive sprocket or the chain itself, such as broken or missing teeth, can lead to an uneven distribution of force and pressure on the chain, causing it to slip or derail.
Insufficient lubrication can cause friction between the chain and the guide bar, leading to excessive heat and subsequently causing the chain to expand or stretch unevenly, increasing the likelihood of it coming off the guide bar.
Regular maintenance, such as cleaning debris and ensuring proper lubrication, can help prevent these issues and keep your chainsaw functioning efficiently by reducing the chances of the chain coming off the guide bar.
How do You Change a Chain on a Pole Saw?
Changing a chain on a pole saw is a simple yet crucial maintenance task that ensures the efficient functioning and longevity of the tool. Before you begin, make sure the pole saw is switched off and unplugged to prevent any accidents. Now, follow these easy steps to replace the worn-out chain with a new one.
Loosen the side panel screws
Start by loosening the side panel screws located on the side of the chainsaw bar. These screws hold the side panel in place and secure the chain on the bar. You can use a wrench or a screwdriver to turn them counterclockwise until they are loose enough. Be careful not to remove the screws completely, as this may cause the internal parts to disassemble.
Remove the side panel
Once the screws are loose, gently remove the side panel by lifting it up and away from the pole saw. This will expose the chainsaw bar and the old chain. Now, you can carefully lift the old chain off the bar, making sure not to touch the sharp teeth on the chain. It’s a good idea to wear gloves for added protection during this step.
Remove the old chain
With the old chain removed, you can now replace it with a new one. Guide the new chain onto the chainsaw bar, ensuring that the teeth are facing in the correct direction and the chain is properly aligned with the groove in the bar.
Once the new chain is in place, put back the side panel and tighten the screws that were loosened earlier. Finally, double-check the chain tension and adjust as necessary to ensure smooth operation and optimal cutting performance. Now, your pole saw is ready for use with a newly-installed chain.
How do You Tighten a Chain on a Pole Saw?
Now that you know how to change a chain let’s learn how to tighten it properly.
Check the tension of the chain
Before adjusting the chain’s tension, make sure to check the current tension and ensure it’s not too loose or too tight. A loose chain can fall off, while a tight chain can overheat, smoke and cause damage to the pole saw. To do this, try to pull the chain down from the center of the bar to check the tension.
Use a screwdriver to adjust the tension screw
Once the tension has been checked, use a screwdriver to turn the tension adjustment screw clockwise to tighten the chain or counterclockwise to loosen it. Make sure to adjust it in small increments to avoid over tightening or loosening it too much.
Make sure the chain is properly tensioned before use
After making the necessary adjustment, recheck the tension by pulling the chain down from the center of the bar. If it’s tightened properly, the chain should move smoothly and still be tight enough. If the tension is not adequate, repeat the adjustment until the right chain tension is achieved.
How Long Should a Pole Saw Chain Last?
The lifespan of a pole saw chain depends on the frequency and type of use. For example, a pole saw used for light trimming can last up to three years, while a pole saw used for heavy-duty work may need to be replaced every few months.
