3.1 Connecting the rivet clamp to the
pressure generator

12
The threads on the hydraulic cylinder and the Booster must be clean and un-
damaged! The securing device must be fully engaged in position. The rivet
inserts must be clean and undamaged!
3.2 Inserting the riveting tool
3.1 Connecting the rivet clamp to the pressure
generator
Two rivet clamps are currently available for use with the riveting tool kit:
1Not included in basic kit VAS 6791
3.1.1 – 3.1.6
Place the riveting clamp on the Compact Booster cylinder. The arrows and dots must be
aligned (position: open). Then turn the rivet clamp to the next marking (position: close) and
lock in position with the lever.
Rivet clamp Art. No. Clamp aperture
NB-45-40 VAS 6790/57 up to 40 mm
NB-230-1401VAS 6790/58 up to 140 mm

3.2.9 3.2.10
3.2.1 – 3.2.8
Insert the rivet insert required for the work process into the rivet clamp recess, as required, or
insert the plunger rod and secure with 1/4-turn. Do not use force.
Select the corresponding counter-piece, locating and locking it in position in the opposite side
of the rivet clamp in the same way. Do not use force.

3.2.13
3.2.9 – 3.2.12
When using a large rivet clamp with a clamp aperture of up to 140 mm, the extension VAS
6790/59 must also be tted. This is screwed either into the seating on the rivet clamp or into
the plunger rod and hand-tightened. Do not use force. The rivet insert can now be placed in
the extension seating (see rivet clamp up to 40 mm). Check that the extension is rmly seated
before and after each riveting operation.
3.3
Each time rivet inserts are to be tted, the bolt and die must be checked for a
correct match rst!
Refer to the areas of application on the following page for this.
3.2.13
Check that the riveting heads, and if
necessary the extension, are rmly seated
after each riveting operation. Rivet inserts
that have come loose present a hazard for
the operator and can lead to damage to
the equipment.

and punch each hole separately.
1If punch rivets are used at a later date, no use may be made of rivet inserts D1, D3 and D4. This means that it is not
possible to center the new punch rivets.
2Position the die for the setting procedure in the deformation which has been created by pushing out through the
metal sheet on the die side.
