● Use the standard parts when replacing the electric parts.
- Confirm the model name, rated voltage, rated current of the electric parts.
● Repair the disconnection of HARNESS securely when repairing the break down.
- If there is any connection error, it causes an abnormal noise and incorrect operation.
● In case that you assemble or disassemble the products with laying it on the side, do work on the work cloth.
- If not, the exterior of products can be scratched.
● Remove dust and foreign materials from harness, connection part, and inspection part thoroughly when repairing the
break down.
- It protects the danger of fire such as tracking and short.
● Check the assembly status of parts after repairing the break down.
- It should be same as the status before repairing.
● Do not pull any electric wires and do not touch an auxiliary power switch with a wet hand.
- There is a danger of electric shock or fire.
● In case any wire or power plug has been damaged, replace it to eliminate any possible danger.
● Do not bend the power cord by force and do not put any heavy object on the power cord.
- There is a danger of electric shock or fire.
● Ground the product if necessary.
- Be sure to ground the product if there is any danger of electric leakage due to water or moisture.
● Be sure to turn off the auxiliary power switch or pull out the power plug during replacement or repair of electric parts.
- There is a danger of electric shock.
