Changing Rough Pump Oil
Periodically, you must change the rough pump oil. The oil tray of the Quiet Cover MS is designed
to collect the oil as it drains from the pump. Please refer to your pump documentation for detailed
information regarding changing your pump oil.
To change the oil:
1 Properly prepare your system for release of primary vacuum.
2 Turn off the rough pump.
3 Turn off the Quiet Cover MS.
4 Unplug the power supply from the Quiet Cover MS.
5 Lock the locking casters to secure the Quiet Cover MS.
6 Open the front access door of the Quiet Cover MS.
7 Tilt the Quiet Cover MS by using the kickstand located at the back of the Quiet Cover MS
(
Using the Kickstand on page 24.) This technique is the most efficient way to drain the pump
oil.
8 Be sure the oil tray is securely seated.
NOTE
The pump sits close to the front of the Quiet Cover MS.

Pull the tray out 1 to 2 inches to avoid oil spillage.
9 Remove the oil drain plug from your rough pump ( Figure 11 ).
