Changing the Roughing Pump Oil
Required Tools
• (1) Oil Catch Pan
• (1) Flat Blade Screwdriver
• (1) 5mm Hex Key (Allen Wrench)
• (~500 ml) Roughing pump oil
Extrel CMS recommends that the oil in the roughing pump for the MAX300
™
-LG be
changed every six months or if the oil is darker than a light amber color. The rate of oil
deterioration will vary depending on the application. The first step in this procedure is to
vent the vacuum system as described previously.
Both the roughing pump and its oil will be hot (up to 80
o
C). After venting the system,
disconnect the inlet line from the enclosure wall and release the slide latch on the left
side of the VacTrac assembly. Pull the VacTrac out of the enclosure far enough to place a
catch pan under the drain plug of the roughing pump. The capacity of this pan should be
considerably larger than the 450 ml (2 cup) capacity of the pump, shown in Figure 9.
