1.3 NOTES ON REPLACING PARTS

Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic
induction.
A
Please attach the Sheet between Power Transistor and Heat Sink when you place Power Transistor in Heat Sink.
If the Sheet is not attached between Power Transistor and Heat Sink, Power Transistor might be damaged.
When you replace sheets (#9 (16170201000) & #10 (16170201000) on the page 14), re-apply silicon
grease (GEM1057) after wiping off silicon grease.
The part listed below is difficult to replace as a discrete component part.
When the part listed in the table is defective, replace whole Assy.
