Brushless Chain Saw Stops Rotating After Two Revolutions158

Brushless chain saws are becoming increasingly popular due to their advantages over brushed models, such as longer life, higher efficiency, and lower maintenance requirements. However, some users have reported that their brushless chain saw stops rotating after two revolutions. This can be a frustrating problem, especially if you are in the middle of a cutting job.

There are a few possible causes for this problem. One possibility is that the battery is not providing enough power to the motor. Another possibility is that there is a problem with the motor itself. Finally, there could be a problem with the electronic speed control (ESC).

To troubleshoot this problem, you should first check the battery. Make sure that the battery is fully charged and that the connections are clean and tight. If the battery is not the problem, then you can check the motor. To do this, remove the chain and guide bar from the saw and then try to rotate the motor by hand. If the motor does not rotate freely, then it is likely that there is a problem with the motor.

If the motor rotates freely, then the problem is likely with the ESC. The ESC is responsible for controlling the speed of the motor. If the ESC is not functioning properly, then it can cause the motor to stop rotating after two revolutions.

To fix this problem, you can either replace the battery, the motor, or the ESC. If you are not comfortable doing this yourself, then you can take the saw to a qualified repair technician.

Here are some additional tips for troubleshooting a brushless chain saw that stops rotating after two revolutions:
Make sure that the chain is properly tensioned. A loose chain can cause the motor to overheat and stop rotating.
Keep the saw clean. Dirt and debris can build up on the motor and ESC, which can cause them to malfunction.
Do not overload the saw. Cutting too much wood at once can cause the motor to overheat and stop rotating.
If the saw stops rotating, let it cool down before trying to restart it.

By following these tips, you can help to troubleshoot and fix a brushless chain saw that stops rotating after two revolutions.
