A portion of the air introduced from the IN side
pressurizes the lubricant inside the bowl. The
remainder of the air passes through the needles o,
and flows to the OUT side. The pressure differential
between the inside of the bowl and the inside of the
sight dome w, causes the lubricant inside the bowl
into the oil passage !0 . The lubricant drips from the
dripping tube !1 , and lubricates the OUT side. The
amount of lubricant is adjusted by the needle o, on
the front face. Turning the needle clockwise increases
the amount of the lubricant, and turning it
counterclockwise until fully opened shuts off the
lubricant. The needle on the side that is not used
should be left fully opened.

dripping amount, and turning it clockwise reduces
the dripping amount. The use of tools, etc. can re-
sult in damage to the unit. From the fully closed
position, three rotations will bring it to the fully open
position. Please do not rotate it any further than this.
