3.UNPACKING WAYS OF MAIN PARTS
3. 1 Product disassembly precautions and steps:
1> General attention:
1.When you remove or repair, please you must unplug the power cord firstly
2.When you connect wire,you are sure to connect wire with wiring cap ,use the tool to
press wiring cap for connecting firmly and use tape to make the line insulation fully.
3.When you plug wire and connect wires, you must insert terminals to the roots for not easily
pulling.
4.When you decorate internal wires,you fix internal wires to avoid encountering moving
parts for example v-belt, pulley,suspend pole, etc or high temperature parts according to
original state.
5.The removing screws must be preserved goodly,because you need screws to install.
6.When you diagnose faults, you are very careful to not get an electric shock if you need to
operate in electricity situation.
