follow the OEM recommend service for the correct sequence. Select appropriate
switch and turn on. Loosen corresponding bleeder until adequate flow is observed.
16. Monitor flow and color of fluid in Bleeder Hose and turn off VACUUM BLEEDER switch
when fluid becomes clear or the desired amount of fluid has been exchanged.
Warning: Monitor both the NEW TANK EMPTY and USED TANK FULL Indicator Lights.
If either illuminates during service, immediately turn all switches off, add new
or remove used fluid as needed and continue with procedure.
Note: The appearance of air bubbles in the Bleeder Hoses is due to air being pulled
around the thread of the bleeders. This is a common occurrence and does not
indicate a malfunction with the process.
