Northern Industrial Tools 109088 - Manual (Page 3)

Fig.2：Connect compressed air 100PSI (7bar) to quick couple D. Open the ball
Valve C. Air will flow out from the muffler E. When the arrow of the vacuum gauge approaches
the red field, after 70-80 seconds, close the ball valve C, then shut off the compressed air. The
aspiration oil is now ready for use.
OIL EXTRACTION
Oils should always be removed when they are hot (158º-176ºF). The suction capacity of the
unit is equal to 2/3 of its reservoir capacity.
Insert the probe into the dipstick tube. Connect the probe to the unit. Open ball valve A taking
care to keep the probe near the bottom of the sump.
EMPTYING THE ASPIRATION OIL
Remove the cap B and manually drain the oil.
First open suction valve A.
CAUTION!
Do not completely overturn the reservoir.
The drained fluids should not come into contact with the oil changer’s venturi valve. If this happens,
unscrew the muffler and blow it out with compressed air.
