When evacuating toxic gases, the pump body and the pump oil may cause toxic. Pay
attention certainly.
① Wear suitable protector (rubber gloves, goggles).
② Before charging the oil, read the「
1.2 Material Safety Data Sheet(MSDS)」.
When the contaminated oil touched skin or came into eye accidentally, follow
the first-aid-treatment of「
1.2 Material Safety Data Sheet(MSDS)」.
Do not apply the different type of vacuum pump oil besides our recommended. If
applying the different type of vacuum pump oil, it may cause the performance
deterioration or shortening the lifetime of the pump.
[Oil Change Procedure]
(1) Unplug the inlet port and operate the pump for 5 sec. We can discharge the remained oil
inside the pump, effectively.
(2) Disconnect the standard exhaust pipe, unplug the drain port, and then drain off the oil.
(3) Plug the drain port; charge the recommended new oil as fixed quantity from the exhaust
port. (see Fig-4)
(4) If the oil contamination is heavy, operating the pump for several minutes with the new
pump oil will be necessary for cleaning the pump inside. Several cleaning procedures should
be necessary for very heavy contamination.
(5) After warming up the pump by operating with the new pump oil, confirm the ultimate pressure.
(6) When depositing the oil sludge on the pump bottom as heavily contaminated oil, the
specified ultimate pressure is difficult to obtain. Overhauling and repairing should be
needed.
