To Check and Add Foreline Pump Oil
Standard foreline pump only
Materials needed
• Foreline pump oil (6040-0621)
• Funnel (9301-6461)
• Hex key, 5-mm, to remove drain plug (8710-1838)
• Screwdriver, flat-blade, to remove top fill cap
Procedure
1 Examine the oil level window ( Figure 5 ).
Note the two lines on the pump left of the window. The oil
level should be between the lines. The foreline pump oil
should be almost clear. If the oil level is near or below the
lower line, follow steps 2 through 6 to add foreline pump oil.
If your instrument is nearing its scheduled time for replacement
of the foreline pump oil, replace the oil instead of adding oil. If
the oil is dark or cloudy, replace it. See
“To Drain the Foreline
Pump” on page 121 for instructions about replacing the foreline
pump oil.
2 Vent the instrument.
3 Remove the foreline pump fill cap.
4 Add pump fluid until the oil level in the window is near, but
not above, the upper line.
5
Reinstall the fill cap.
6
Pump down the instrument.
