4. Operation
4.1 Caution on Operation
WARNING
This pump is not pressure-proof.
①
Never run the Vacuum pump on blocking up the exhaust outlet,
putting any device that hampers the gas passage. There is a risk that
pressure in the Pump rises, and the main body of the Pump and the
oil level gauge might explode, or the motor become an overload.
②
This product is not made as the withstand pressure structure.
Ensured pressure value of the Pump shall be 0.03MPa (0.3kgf/cm2)
(Gauge pressure).
If any valve was put to a pipe after the Exhaust outlet, check and
ensure that it is open.
CAUTION
①
Never fail to lubricate the machine.
If the lubrication oil came down lower than limit level during operation,
it might give damage on the bearing, gear and rod sealing and result
in leak, noise, motor overload and operation stop.
②
The Pump oil might deteriorate in a shorter time depending on the use.
It is recommended to replace the first Pump oil within ten days after
operation start and see how it got dirty to determine the oil
replacement cycle.
③
If the Pump breathes in a lot of water or the like, you should replace
the oil more frequently. If kept operation without getting rid of
breathed water, it would deteriorate lubrication of the oil and further
help corrosion of the Pump inside and result in causing a failure.
Do not store this product keeping sucked the water.
④
If the Pump breathed in chemical material such as acid, immediately
replace the oil as it would cause the rust during the stop in one night
to make the system e not applicable to operate.
We shall be not liable to the durability to chemical material.
When using this product in suction of chemical material, it is out of
range of warranty.
⑤
You should also replace the oil if breathed in the solution to
deteriorate lubrication of the oil as it would also cause biting inside.
You shall have a risk if breathed in the solution in operation even you
replaced the oil.
When using this product in suction of solvents, it is out of range of
warranty.
