1、Precautions before commissioning：If the original machine is a split motor（The stator and rotor can be separated），It is necessary to install the housing and tighten the screws first，You can twist the square shaft gently by hand，Make sure the motor is fixed，To power on, press the switch。Because the split motor is not fixed, even if it can rotate, it will rotate disorderly，It is easy to damage the control board！If the machine is not installed properly, the control board may be damaged，Please re install according to the above requirements。
2、The control board is suitable for the maintenance of various brands of brushless electric wrench、Substitution，Directly replaceable，Easy to install，Please refer to the following wiring diagram for wiring。Pay attention to distinguish the positive and negative poles of power supply when wiring（Red positive black negative），In order to avoid the wrong connection burning board！The motor is only connected to the three thickest wires，Regardless of color line order，If the motor reverses，Just switch any two motor wires，If the motor has hall，5There’s no hall wire to connect，No impact on function。
3、Only buy control panel, not switch，Please confirm that the original switch is8Wire with light and socket size is9mmThe ability to match，When installing the original switch on the board，It has to be vertical，Avoid bending the needle in the socket on the board with improper force, resulting in the failure of the tester，If the board is damaged, the buyer is responsible！
4、The control board is divided into wiring type and plug-in type，The size and function are the same，Random delivery，Note or leave a message if necessary！Big switch、Two sizes smaller，There is a size chart below，Its function is the same，Please buy according to the size（Dayi2106It’s a little switch）。
Driving voltage divider18V(5Series lithium battery，Fully charged is21V）。
Driving power：300WBrushless induction or non induction three phase motor。
Protection function：Battery high and low voltage protection、Circuit over temperature protection、Over current protection、Self discharge protection。
The function of the plug-in is the same as that of the wiring，Random delivery，Please note if you have any requirements！
