Refilling or Replacing the Lubricating Fluid

DANGER
!
Thoroughly purge the pump for at least 15 minutes to remove all toxic gases
before opening the pump for any reason.
CAUTION
!
Before attempting to add any lubricating fluid into the pump, it is imperative that
the secondary reservoirs are drained first. Failure to do so could result in
lubricating fluid being forced into the vacuum area of the pump.
CAUTION
!
When changing or replenishing lubricating fluid, be sure to stop the pump and
allow the pump to return to atmospheric pressure. Because the lubricating fluid
reservoir is under vacuum, the pump can be severely damaged if the lubricating
fluid port plug is removed while the pump is in operation, or not at atmosphere.
