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.3)
(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.
