Connect the PrimeMate Oil Change System
to the Vacuum Pump
Position the PrimeMate Oil Change System near your vacuum pump such that
the hose from the rear of the PrimeMate Oil Change System easily reaches the
coupling body on the vacuum pump. Turn the vacuum pump off. Push the
coupling insert, which is attached to the hose, into the coupling body on the
vacuum pump until it securely snaps in place. The coupling insert may be
removed from the coupling body by pressing on the tab on the side of the
coupling body.
