Before transporting
Before using the
Vakuflex 280,
check it for any externally recognisable damage or flaws.
Now, fix the
Vakuflex 280
on the lifting device or on a crane hook.
Then set the two manual valves to the RELEASE position.
Turn on the device with the button "On/Off" (3). The light is green now. The pumps must
start up if the vacuum is insufficient. The Pump indicator light (4.1 / 4.2) indicates that the
pumps are active. If this is not the case, working with the
Vakuflex 280
is not permitted
(see Troubleshooting).
The signal tone signalises insufficient vacuum in the lines to the suckers. The existing
vacuum in the hose system of both vacuum circuits can be checked on the two vacuum
meters (5.1 / 5.2). After a short time, a vacuum of at least -0.65 bar should have built up in
each tank. The vacuum pumps switch off when -0.7 bar vacuum is reached. This should
be the case after a short time.
In order to check the vacuum, the individual suckers (two per vacuum circuit) must be
blocked from the vacuum reserve tanks using the vacuum couplings. Then the two manual
valves (2.1 / 2.2) are set to SUCTION. The indicators of the two inspection vacuum meters
(5.1 / 5.2) must then be in the green area. Then switch the device off with the switch (3)
and wait ten minutes. During this time the indicators of the two inspection vacuum meters
may not move.
If only one indicator changes, the device is leaking and may no longer be used until the
error has been corrected. However, if this is not the case, the Vacuflex 280 is ready for
