Precautions for inspection and repair
Inspection
Verify that the power cord is tightly connected on the machine.
Be careful to avoid electric shock.
Repair
Power off the supply before repair work begins.
Keep things tidy and in order during repair work.
When changing more than one part, identify the parts that are damaged and reuse the
serviceable parts.
During the dismantling or assembling process, do not damage other parts and PCB.
Be on the alert for loose or disconnected connectors during repair.
Do not leave any screws or other foreign objects in the unit after it is assembled.
Carry out test operation of the machine after the repair work is done.
It is preferable to perform the repair work on a carpet to prevent scratching or dirtying the
unit.
Clean the workplace after repair work is completed.

二.故障检修流程图 Troubleshooting Process
在修理或者替换零配件过程中注意下面几点：
A. 在拆卸连线，移动连接器，或者替换部件前一定要断开电源线插头。
B. 因为半导体（像集成电路，或者其它的）很容易被静电损坏，所以当要触摸 PCB 前，请确保你的身
体和大地有连线（佩带静电手环），或可以将手放在地端，以释放身体上所带的静电。
Notes for repairing chair or replacing parts
A. Make sure the power is off when you tear down the wires, move terminals or replacing parts.
B. The semiconductors( like IC or something else) will easily be damaged by static.
So you touch the PCB before, please make sure your body is connected with the ground.
