Common Safety Instructions for Vacuum Series
Warning
Before selecting or using PISCO products, read the following instructions. Read the
detailed instructions for individual series.
1. If there is a risk of dropping work-pieces during vacuum suction, take a safety
measure against the falling of them.
2. Avoid supplying more than 0.1MPa pressure constantly in a vacuum circuit.
Since vacuum generators are not explosive-proof, there is a risk of damaging
the products.
3. Pay attention to drop of vacuum pressure caused by problems of the supplied
air or the power supply. Decrease of suction force may lead to a danger
of falling work-piece so that safety measure against the falling of them is
necessary.
4. When more than 2 vacuum pads are plumbed on a single ejector and one of
them has a suction problem such as vacuum leak, there is a risk of releasing
work-pieces from the other pad due to the drop of the vacuum pressure.
5. Do not use in the way by which exhaust port is blocked or exhaust resistance
is increased. Otherwise, there is a risk of no vacuum generation or a drop of
the vacuum pressure.
6. Do not use the product in the circumstance of corrosive gas, inflammable
gas, explosive gas, chemicals, seawater and vapor or do not expose the
product to those. Never allow the product to suck those things.
7. Provide a protective cover on the products when it is exposed to sunlight.
8. Carry out clogging check for silencer element in an ejector and a vacuum
filter periodically. Clogged element will be a cause to impair the performance
or a cause of troubles.
9. Before replacing the element, thoroughly read and understand the method of
filter replacement in the catalog.
10. Make sure the correct port of the vacuum generator by this catalog or
marking on the products when plumbing. Wrong plumbing can be a risk to
damage the product.
11. Supply clean air without sludge or dusts to an ejector. Do not lubricate by a
lubricator. There is a risk of malfunction or performance impairing by impurities
and oil contained in the compressed air.
12. Do not apply extreme tension, twist or bending forces on a lead wire.
Otherwise, it may cause a wire breaking.
13. Locknut needs to be tightened firmly by hand. Do not use any tool to tighten.
In case of using tools to tighten the locknut, it may damage the locknut or the
product. Inadequate tightening may loosen the locknut and the initial setting
can be changed.
14. Do not force the product to rotate or swing even its resin body is rotatable. It
may cause damage to the product and a fluid leakage.
15. Do not supply an air pressure or a dry air to the products over the necessary
amount. There is a risk of deteriorating rubber materials and malfunction due
to oil.
16. Keep the product away from water, oil drops or dusts. These may cause
malfunction. Take a proper measure to protect the product before the
operation.
