ATTENTIoN
y The position of the „O" ring in the handle is used to set
two different functions of the rivet drill adapter that are
necessary for installing rivet nuts.
y When the „O" ring is extended on the edge of the han-
dle (fig. 1A), the rivet mandrel turns together with the
chuck head of the drill, which is necessary for screwing
in the rivet nut on to the rivet mandrel of the adapter to
install the nut and then for unscrewing an already
pulled rivet nut from the mandrel of the rivet drill
adapter.
y When the „O" ring is inserted in the
handle (fig. 1B), the rivet mandrel slides
in or out depending on the rotation
direction of the chuck head of the drill,
which is necessary namely for pulling the rivet nut that
is inserted in a pre-drilled hole.

y The size of the rivet mandrel needs to be selected accor-
ding to the size of the rivet nut. The size and length of
the rivet nut must be selected to respect the diameter
and depth of the pre-drilled hole, otherwise the mate-
rial being joined will not be joined properly. The size of
the rivet nut must then correspond to the size marked
on the rivet mandrel and on the rivet nosepiece in the
form, e.g. M5, M6, etc.

ATTENTIoN
y The rivet drill adapter may only be used with rivet man-
drels and nosepieces that are supplied with this rivet
drill adapter model. Using rivet mandrels and nosepie-
ces intended for other riveting devices is not permitted
even when it is possible to screw them into this adapter
as this could result in damage to the rivet drill adapter.
The replacement of rivet mandrels is described in
individual steps of the procedure in figures 1C to 1H.
a) Retract the „O" ring on the handle of the rivet drill
EN
adapter into the handle as shown in fig. 1B.
b) Using an assembly wrench, screw out the rivet nose-
piece as shown in fig. 1C.
c) Screw out the flange as shown in fig. 1D.
d) Take the spring off the rivet mandrel as shown in fig. 1E.
e) Using an assembly wrench, screw out the rivet man-
drel as shown in fig. 1C.
f) Then screw the rivet mandrel with the marked size
corresponding to the size of the rivet nut into the
thread (fig. 1G).
Clamping the rivet drill adapter into the chuck
head of a drill (fig. 2)
a) Retract the „O" ring on the handle of the rivet drill
adapter into the handle as shown in fig. 1B.
b) Open the chuck of the drill and insert the hexagonal
shank of the rivet drill adapter fully into the chuck.
c) Then firmly clamp the chuck of the drill to properly
secure the rivet drill adapter in the drill.
Iv. Installing rivet nuts
•
ATTENTIoN
y To set the optimal torque and to become acquainted with
the methodology of work with the rivet drill adapter, first
perform practical tests on a piece of sample material.
Initially set a lower torque, which can be increased if
insufficient. Setting a torque that is too high will result in
the thread of the rivet mandrel being torn out of the rivet
nut, which likewise damages the thread of the rivet man-
drel and causes wear to the internal parts of the adapter
that is not covered by free warranty repairs/replacement
of the rivet drill adapter. In the event that the thread of
the rivet mandrel is torn out even when the lowest possi-
ble torque is set on the drill, it is necessary to select a drill
with a lower torque, otherwise the rivet mandrel thread
will become worn out.

WArNINg
y For safe work, it is necessary to work at rotation speeds
of < 20 rpm.
y Set the lowest speed level on the drill and very gently
control the speed by slightly pulling on the trigger.
