Dear JR Liang.
Asno will planing to change oil new type , Asno request to Ya Thai , that if they change oil to new type , if make effect to chemical and parts or not?
About , why 7 min. because ep-52 in rack line use time 70 sec/rack ( 6rack/tank )
After we tested complete , I think that not have problem , and then I sent report to Murata San for send to Takahashi San ( QA ) about result after this test.
