CAUTION:
(a) Perform this test at normal operation fluid
temperature (50 - 80°C or 122 - 176°F).
(b) Measurement can be made with a 1,000 rpm
test, but if tests are to be made at 1,800 and
3,500 rpm, it would be safer to road test or
on a chassis dynamometer because an on-
stand test could be hazardous.
