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.
⑥
The Pump oil might deteriorate in a shorter time depending on the
use. It is recommended to replace the first Pump oil within 10 days
after operation start, and see how it got contamination, viscosity and
discoloring 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.
⑦
Caution shall be required for the operation under high pressure
range.
(1) In the continuous operation of VD90C, perform it in the inlet pressure
at 1000Pa or less. The temperature of the Pump becomes very high
temperature, and the Pump may break.
(2) Continuous operation one hour or more under high pressure 1000Pa
or more would increase the oil volume that are discharged as the oil
mist and cause rapid parts wear or cause a trouble such as burning.
You are recommended to control the oil level on regularly supplying
the Pump oil. Also, it is recommended to install the oil recovery
mechanism (option).
The maintenance cycle might become shorter.
(3) Upon performing the continuous operation at the high suction
pressure, the oil temperature becomes very high temperature. As a
result, the oil rapidly deteriorates, and the attained pressure and the
exhaust speed go bad, and it causes the rapid abrasion of parts and
the failure of seizing up. Frequently perform replacement of the
Pump oil. Also, it is effective to cool the oil inside the Pump by
installing the oil cooler.
