(1) Depending on the use, the vacuum pump oil may deteriorate in a
quite short period of time.
It is recommended to do the first replacement of the vacuum pump
oil within 10 days, evaluate the degree of contamination of oil, and
then determine the oil replacement cycle.
(2) If the pump suctions a large amount of water etc., replace the oil
frequently. Continuous use of the pump with water suctioned
accelerates corrosion of the pump part, which may result in
defects.
Do not store with water suctioned.
(3) If it has suctioned chemical agents, such as acid, replace oil
immediately after the suction since it is possible that the pump
part is being corroded causing defects during one-night downtime.
Durability to withstand chemical agents is not guaranteed.
(4) Pay attention to increase in suction gas due to leakage from the
outside, gas emitted from the workpiece, etc.
(5) An extremely high back pressure may cause loss of the pumping
action of this unit, leading to a rise of oil to the vacuum chamber.
(6) When you pumping a lot of gas and drive with back pressure
being high, oil may decrease early.Because there is individual
difference to the limit quantity that can exhaust gas, the
decrease of the oil changes.
CAUTION
