OPERATION
1. When items are to be riveted
together, the hole diameter must
be nominally larger than the outer
diameter of the rivet. Ensure that
the hole is perpendicular with the
surface of the workpiece
components.
2. Insert the rivet into the hole of the
workpiece components.
3. Pull the handle back to extend
the rivet gun to its full length.
• This will enable the rivet stem to
enter the rivet gun as far as it will
go, with the handle fully
extended.
4. Ensure the rivet gun is
perpendicular to the work piece
and the flange of the rivet is
pressed against it.
5. Push the rivet gun handle fully
forward to expand the rivet.
6. If the rivet stem does not break off
at the first stroke, pull back the
handle and repeat step 6.
7. Extend the rivet gun by pulling the
handle back and the broken stem
should be ejected from the
nozzle.

the gun shield clockwise to
tighten (anti-clockwise to loosen).
2. Pull the handle to extend the
riveter and to tighten the internal
claws.
3. Re-tighten the locking nut.
