A. Preparing air riveter
Follow the steps below to install the required rivet nozzle:
– Loosen and remove the screw (part 37). To make it easier
to replace the nozzle, unscrew the nozzle holder by 2 or 3
turns (part 38). Then fit the required nozzle (part 37 ~ 37-3)
onto the nozzle holder.
– Loosen the nozzle holder (part 38) and remove it from the
cylinder body (part 53).
– Loosen the clamps holding cone (part 39) from the cone
holding head (part 42).
– Take out the clamp and the clamp opener (parts 40 and 41);
then replace them with the relevant clamp and clamp
opener.
– Then install the clamps holding cone and check adjustment,
so that it can match the caliper wrench (part 63).
– Finally, assemble the nozzle holder and lock it with the
relevant, previously loosened nut.
Fixing problems
Stop using the tool immediately if any of the following problems should occur. Any repair or replacement must be performed by a
trained person or an authorized service centre.
Problem Cause
Rivet jammed Wrong size of rivet
Filings jammed in part 39
Filings on part 37
No suction Shut-off valve has not been opened
Air leaking Damaged O-rings
Loose screws
Air riveter runs slow Air line is loose
or suffers a loss of
Exhaust port (part 20) is blocked
power
Operating pressure is too low
Tips
Clean parts 38~42 and oil every 500 uses.
Replace parts 40~43 every 2,000 uses (if stainless steel rivets
with Ø 6.4 mm are pulled).
The rivet container (part 59) must be emptied when it reaches
approximately 35 rivets.
B. Using air riveter
– Open the air inlet (part 65), to let air into the air riveter.
While using the air riveter, the air inlet (part 65) must be
open, to allow rivet suction.
– Turning the adjusting screw in part 58 allows suction
adjustment. Turning the screw clockwise allows suction to
be reduced.
– Use the nozzle with the relevant rivet; then press the trigger
(part 33) to release the rivet rod into the rivet container (part
59).
– When the rivet container (part 59) is full, unscrew the
adapter (part 61) and empty the rivet container.
– After cleaning it all, screw the adapter (part 61) into the rivet
container (part 59). Then use the air riveter again, following
the steps above.
Remedy
Different rivets require different nozzles, clamps and clamp
openers. Read manual and check rivet size again (fig. 1).
Use adjustable wrench or wrench 63 to remove part 38;
then use supplied wrench to remove spare part 39.
Remove any deposits from parts.
Lock parts 38 and 39 (fig. 1).
This might occur when aluminium rivets are pulled.
Use a sharp tool to remove filings from part 37.
See fig. 2.
Replace O-rings.
Tighten screws.
Reinstall and tighten airline.
Clean out exhaust port (part 20).
Increase operating pressure to 5.9÷6.6 bar.
