Lithium saw reversal reason analysis and solution

First, the principle of reversal

The reversal of the lithium saw refers to the phenomenon of the tooth rotating in the opposite direction. This reversal phenomenon usually appears suddenly in the process of using lithium chainsaws, completely destroying the construction progress, and bringing great hidden dangers to the life safety and health of workers.

In order to avoid the phenomenon of inversion, it is necessary to understand the principle of inversion. When the lithium saw is working normally, the force emitted by the motor drives the saw blade, and the saw blade rotates and cuts. The principle of the reversal phenomenon is because the saw blade because of inertia, resulting in a change in the rotational inertia of the motor, can no longer rotate the saw blade, resulting in rotation in the opposite direction.

Second, the reason for reversal

There can be many reasons for the reversal phenomenon, and we have listed some of the main reasons.

1. Insufficient battery power: Insufficient battery power will directly cause the output current of the motor to be unstable, thus affecting the speed and reversing the saw blade.

2. Saw blade passivation: If the saw blade is too blunt, it will also lead to reversal phenomenon, because the bending elastic force of the saw blade is insufficient, resulting in the saw blade constantly subjected to friction when working, ultimately affecting the rotation of the motor, resulting in reversal.

3. Saw blade installation is not correct: If the saw blade is not fixed correctly when installed, it will also lead to the occurrence of reversal.

4. Motor temperature is too high: too high motor temperature will lead to insufficient motor output torque, unable to rotate stably, so that the saw blade is reversed.

Third, reverse the solution

1. Replace the battery: If it is found that the battery cannot be fully charged by timely charging, it is recommended to replace a set of batteries.

2. Replace the saw blade: When the saw blade is passivated, it is recommended to replace the saw blade in time.

3. Correct installation of the saw blade: When installing the saw blade, make sure that it is fixed in the correct position.

4. Reduce machine load: If the motor temperature is found to be high, it is recommended to let the machine rest for a period of time before continuing to work to reduce the machine load.

In short, the lithium saw reversal may be caused by a variety of factors. Either way, you need to identify the cause before you can fix the problem. Finally, we hope that the above mentioned solutions can help you solve the lithium saw reversal problem.
