3.2 Vertical clamping start-up
Check the seal is set correctly in the groove before each
use of the electrical vacuum clamp. Secure the vacuum
gripping machine with two G-clamps on a stable support
base, with the fixing plate equipped with the shutoff
valve facing backwards, as indicated in figure 3. Check
that valve (Fig. 3) A for this plate is closed. The pump
will cause a vacuum in the suction plate in front. You
can now place the part to be worked on this suction
plate. To remove the part just turn off the vacuum pump,
holding it by hand to prevent it from falling.
3.3 Gripping small parts
The suction plates can be divided into sections to grip
small parts. To do this, just place a piece of rubber
seal, included in the standard equipment, in any of the
grooves C (Fig. 1) in the suction plate, taking special
care to ensure the ends of this seal fit tightly with seal
B (Fig. 1) so that a vacuum can be produced.
3.4 Working with the extension module
Check the seal is set correctly in the groove before each
use of the electrical vacuum clamp.
With long and heavy work pieces, an extension module
can be used for a secure support. The connection hose
is connected to the basic module and the extension
module with a quick coupling.
In this case it is also important to separate the suction
plate not being used from the vacuum using a blocking
valve.
3.5 Detaching the work piece
Closing the blocking valve (Fig. 1) (A) disconnects the
vacuum and the work piece can be easily removed from
the suction plate.
When detaching the work piece always
raise it slightly so you do not damage the
seal or take it out of the groove.
WARNING
Risk of accident
• Always keep the work piece tight before you open
the blocking valve.
• Make sure the work piece cannot fall or tumble after
you have used the blocking valve.
Work pieces must have flat and even surfaces.
After use, switch off the pump with the on-off switch
and unplug the plug from the socket.

Risk of accident – When using the device

always keep in mind:
• The clamp unit must be placed firmly on the support
base and must not be movable.
• Before each use check the rubber seal on the suction pla-
te and the rubber seal on the underside. Never work with
a damaged suction plate or damaged rubber seal.
• Clamp the work piece in a way that its centre of gravity
is on the suction plate.
On each side the work piece must overlap the border of
the rubber seal by at least 1 cm.
• Do not push or pull the clamped work piece with
force.
This might lead to a detachment of the work piece from
the suction plate.
3.6 General hazard warnings and problem solu-
tions
WARNING
Risk of accident
• Before working on the device always unplug the plug
from the socket.
• Make sure that the seal is set correctly in the groove
before each use of the vacuum clamp.
• Always place the vacuum clamp in a way that the seal
cannot be damaged or taken out of the groove.
• Change the seal in time. The vacuum can be affected
by dust, shavings, etc.
• Exchange the seal when it starts getting porous.
• Only even and flat plates can be clamped.
• For work pieces larger than approximately 1.2 m an
additional extension module with a connector hose
can be used.
• Ensure that the voltage and frequency of the power
supply are in line with the indications on the device's
specifications plate.
• In North America you are only allowed to use VIRUTEX
machines with a voltage of 120 V/60 Hz.
