Oil change using external pressure source

 Close the ball valve (1).
 Insert the nozzle (6) in the hose coupling (3) on the oil separator tank (5).
 Connect the nozzle to external pressure source. Pressurize the oil separator tank (5)
until the pressure gauge (2) on the oil separator tank (5) shows approximately
43.5 psig.
 Remove the nozzle (6) from the hose coupling (3) on the oil separator tank (5).
Drain the oil from the oil separator tank:
 Prepare a clean container to catch escaping oil.
Attention!
 Hang the oil drain hose (10) into the container and secure.
 Slowly open the ball valve (9). The remaining pressure in the oil circulation forces out
the oil. When air escapes, close the ball valve (9) immediately.
