d) Remove the nozzle from the oil bottle, 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.
e) 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: 800N⋅cm)
CAUTION
If the O-ring at the inlet is damaged, gas leak will
result.
f) If oil has spilled over, wipe it up.
g) After replacing the oil for the turbo blower, be sure to conduct
automatic aging as described in Subsection 4.3.5.
CAUTION
If you do not conduct automatic aging after
replacing the oil for the turbo blower, correct
discharge is not possible, which can become a
cause of trouble.
h) If there is oil left over, put the inner lid back on the bottle, and
keep the bottle in a dark, cool place.
CAUTION
Once you open a new oil package, you should use
it within six months. Even for an oil package not
opened, you should use it within one year. Never
use old oil whose validity has expired. Using such
oil can cause a failure in the turbo blower.
