6 months.

be careful not to put dust in turbo blower.

5.3.3 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.

NOTE
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.
(2) Replacement method
1) Stop the oscillator, and turn off the power.
2) Remove the maintenance panel.
3) Remove the oil inlet plug. There is an O-ring on it. Be
careful not to damage it. A missing or damaged O-ring can
lower the exhaust capacity of the pump.
4) Insert the drain tube into a drain oil pot.
5) Fully open the drain cock.
