3.2 Oil filling

For both the two oil level gauges, check that the oil level is between the upper and lower level lines.
If the oil level is between the level lines of the oil level gauges when operation stops, the pump can
be operated.
If the oil level is not between the level lines of the oil level gauges when operations stops, check that
the pump stops and the inner pressure in the pump is the atmospheric pressure, and then remove
the oil filler plug and fill the oil so that the oil level is between the level lines of the oil level gauges.

(1) Before starting work, be sure to turn off the power supply.

During the work, never turn on the power supply. Otherwise you may
get injured.

(2) Immediately after the operations stops, the pump temperature is

high. Wait for a while until the pump temperature becomes low and
then perform inspection. Otherwise you may get burned.

If it is used to exhaust hazardous gas, it goes without saying that not
only the pump body but also the pump oil will be toxic. Take due care.

(1) After the operation, the oil level decreases by approx. 1 cm. If the

operation is started under the conditions where the oil level is
between the level lines of the oil level gauge at a stop, there is no
problem if the oil level is not between the level lines of the oil level
gauge during the operation.

(2) Do not operate without oil in the pump. Otherwise the pump is

broken.

Use our specified vacuum pump oil. If other oil is used, it is not covered
by the warranty since the pump performance may deteriorate and its life
is shortened.
