following safety
precautions:
1.1 Safety Precautions
1.1.1 Use Genuine Parts
The components of the washing machine have safety features such as non-combustibility
and voltage with standing. Therefore, always use thesamepart as suggested by the
manufactuerer.
In particular be sure to use only designated parts in case ofmajor safety parts identified by
themanufacturer.
1.1.2 Grounding
Connect the grounding wire to the shell plate ,and bury it under at least 25cm ofearth:
alternatively, connect the ground wire to the appropriate pin on a properly grounded
power receptacle. Never connect the wire to atelephone line, lightning rod, or gas pipe.
1.2 Servicing Precautions
1.2.1Observe Warnings
Be sure to follow special warning and precautions that are described on part labels and
in the instruction book.
1.2.2 Parts Assembly and Wiring
Be sure to use insulation material(such as tube and tape).And be sure to restore all parts
and wires to their original position. Take special care to avoid contact with sharp edges.
1.2.3 Perform Safety Checks after Servicing
After servicing, check tosee that the screws, parts, and wiring are restored totheir
original positions, and check the insulation between the external metals and the socket
plug. In addition, place the washing machine in a level position (less than1 degree)to
prevent vibration and noiseduring operations.
1.2.4 Insulation Checks
Pull out the plug from the power receptacle, pour water into the spin tub, and then set
the timer.
