2 Take out a bottle of oil from an oil kit (A04B-0800-K326).
Remove the nozzle from the bottle, and take off the inner
lid, then put the nozzle back on the bottle.
Put the supplied tube into the nozzle, insert the tube into the
oil inlet, pour oil being careful to cause no foreign matters
to get into oil.
Pour oil while checking the oil level from the oil level
window until the oil level reaches the three-quarter position
from L between L and H. Either superfluous or insufficient
oil can be a cause of trouble.
3 Lightly wipe the area around the oil inlet, hexagonal-head
screw on the oil inlet, and O-ring with a clean cloth or
paper, then check that there are no foreign matters.
Foreign matters getting into oil may cause a turbo blower
fault. Check that the O-ring is fit to the hexagonal-head
screw on the oil inlet, then tighten the screw (recommended
torque: 7.85Nm)
4 If oil has spilled over, wipe it up. Otherwise, the peripheral
equipment may be affected adversely.
5 If there is oil left over, put the inner lid back on the bottle,
and keep the bottle in a dark, cool place.
(3) Replacement method
1 Get a container for oil drain on hand, and put the tip of the
drain tube into the container.
2 Turn the oil drain cock through 90 degrees, and the oil will
start draining. Opening the oil inlet during draining can
drain oil fast.
3 After all the oil has been drained, close the oil drain cock
by setting it back in the initial place.
4 Supply oil by following the same procedure as for
replenishment.
CAUTION
After replacing the turbo blower oil, perform
discharge aging.
