
When you refill the separator receiver tank with compressor oil, stop the
engine, and make sure that the pressure gauge indicates 0psi (0bar) and
there is no residual pressure in it, and then gradually loosen the oil filler cap
for refilling oil.

Note residual pressure in the receiver tank could force both extremely hot
compressed air and oil to jet out and you may be scalded or seriously injured.


After stopping the engine, confirm that the pressure gauge indicates 0psi
(0bar) and there is no residual pressure in it, then open the drain valve
gradually to drain the compressor oil.

Should any residual pressure be left in the separator receiver tank, hot
compressed air and hot compressor oil jetting out could cause burning or
serious injury to persons nearby.

A long-time operation with condensate accumulated could cause rust in the
interior of compressor air-end, resulting in serious trouble.
The machine should be on level before checking
compressor oil level.
The oil level of this machine will vary depending on
whether it is in operation or not. When it is not in
operation, make sure that the compressor oil level is
above the upper limit line as shown in red on the
level gauge plate. Replenish the oil if short.

separation performance and the like.
Gradually opening the drain valve [B] fitted under
the separator receiver tank [A] as shown in the fig,
drain the condensate.
When all the condensate is drained away and the
compressor oil starts to come out, close the drain
valve.
Drain the condensate in container [C], and then
dispose of condensate according to the designated
regulations.
When the fluid is difficult to distinguish by appearance,
use a gloved hand and check its viscosity via touch to
determine whether it is condensate or compressor oil.
