When evacuating toxic gases, the pump body and the pump oil may cause
toxic. Pay attention certainly.
・Wear suitable protector (rubber gloves, goggles).
・Before charging the oil, read the「1.2 Safety Data Sheet(SDS)」. When
the contaminated oil touched skin or came into eye accidentally, follow
the first-aid-treatment of「1.2 Safety Data Sheet」.
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. (Refer to 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.
