FITTING AND STORING THE NOZZLES
Choose the rivet to be used for the job. The CHT878 Hand Riveter is equipped
with a choice of 5 different size nozzles to suit different rivets.
The sizes available are:
• 3/32” (2.4 mm)
• 1/8” (3.2 mm)
• 5/32” (4.0 mm)
• 3/16” (4.8 mm)
• 1/4” (6.4 mm)
NOTE: The dimensions are
engraved on each one.
• Always store the unused nozzles by screwing them back into the stem
collector of the riveter for safe keeping.
Screw your chosen nozzle into the tip of the rivet gun, finger tight.

OPERATION
1. When items are to be riveted
together, the hole diameter must
be nominally larger than the outer
diameter of the rivet. Ensure the
hole is perpendicular with the
surface of the workpiece
components.
2. Insert the rivet into the hole in the
workpiece.
3. Open the arms of the riveter as
wide as possible.
• This will enable you to insert the
rivet stem into the riveter as far as
it will go.
4. Ensure that the riveter is
perpendicular to the workpiece
and the flange of the rivet is
pressed against it.
5. Close the handles together to
expand the rivet.
6. If the rivet stem does not break at
the first stroke, open the handles
and repeat until the components
are squeezed tightly together and
the rivet stem breaks off.
7. The broken stem should be
ejected from the nozzle and be
caught in the collection tank.
8. Unscrew the collection tank and
dispose of the contents when full.

ADJUSTMENT
If the internal claws of the rivet gun
fail to grip the stem of the rivet, the
riveter will need adjusting.
1. Loosen the locking nut and rotate
the riveter shield clockwise to
tighten (anti-clockwise to loosen).
2. Open the handles to relax the
riveter and to tighten the internal
claws.
3. Re-tighten the locking nut.
