Using Tips:

1,Please make sure that the grinding pen chuck is closed before use.If it is not turned off, the machine will automatically shut down.

2,Please use a 5V-2Achargingplug to achieve the fastest charging.

3,When changing the drill bit, it is necessary to shut down or adjust the speed to zero, and then unlock to change the drill bit. Because when the machine is running at high speed, sudden unlocking will cause the circuit board to crash under high load and cause high temperature, which could lead to circuit board burn out.

4,When the screen displays "Er2", it means that the power capacity is exhausted and needs to be fully charged before use. The machine cannot be used while it is charging.

5,Please note that you need to remove the white protective card under the controller button when you use it for the first time.

6,In order to prolong the service life of the power capacity, please try to charge it when the power is not lower than P30.

7,There will be natural discharge during long-distance transportation. If the product cannot be turned on after receiving it, please charge it first.

8,Please open the inner support of the package box. The charging cable and metal polishing head kit are all under the inner support of the package box.
