OPERATING THE AIR RIVETER
Select a rivet of a size which is suitable for the workpiece to be riveted.
Replace the nosepiece with one which matches the size of the rivet to be used.
(Refer to item in “
Pr paration B for Us ” on page 7.)
Drill a hole of appropriate size (0.1 to 0.2 mm larger than the
diameter of the rivet) into the workpiece.
Insert the rivet into the hole.
ATTENTION:
Some rivets have mandrels with sharp ends.
Be careful not to injure your fingers on these ends.
Place the nosepiece of the air riveter over the mandrel of the rivet.
Gently press the nosepiece of the air riveter against the
workpiece. After checking that there is no gap between the
nosepiece and the workpiece, press the switch.
AWhen you pull the switch or during the keeping pull position, you may find a
little air leak from the point of this switch. This is not the defective of the
quality but the normal condition.
The rivet will be set into the workpiece.
Release the switch, and then tilt the air riveter to remove the cut mandrel from the
nosepiece or safety cap.
NOTE: Make sure that the cut mandrel has been completely removed before proceeding to the next riveting.
＜Operating temperature＞The ambient temperature for working is within the range of 4° ~ 35°C (40° ~ 95°F).

MAINTENANCE
After long periods of use, debris from rivet cut mandrels and other foreign materials tend to build up in
various parts of the tool, and the hydraulic oil level also drops, both of which can lead to operating
problems. The tool should be cleaned periodically.
Jaw maint nanc
Also refer to this section when replacing parts.
◎If debris builds up, the jaws will not move smoothly and normal operation will not be possible.
◎The jaws should be cleaned on average once every 3,000 riveting operations.
