4.3.2 Changing the Exhaust Pump Oil
(1) Check method
Watch the oil gauge, and check that the oil level is between
graduations L and H. Also check whether the oil is dark.
If the oil level is below L, add oil to the turbo blower or replace
the oil in it. If the oil level is above H, drain until the oil level
becomes below H.
The exhaust of the turbo blower contains oil mist. The exhaust
pump will capture oil mist, and the amount of exhaust pump oil
increases with time. When the oil has increased too much, the
filter gets immersed in the oil, possibly causing white mist to
come out from the pump, or oil to leak. Furthermore, the exhaust
capacity may get lowered, or the pump may be damaged.
