There is a risk that the spent mandrel will be clogged inside, causing a fault of the equipment.
WARNING
㸺Operating temperature㸼The ambient temperature for working is within the range of 4~35Υ(39.2~95°F). Although condensation may occur on the lower part of Grip Cover depending on
the number of rivets used, and the usage environment, that does not indicate a defect.
Wipe off around the part before using the unit.
Note ەMake sure that the cut mandrel has been completely removed before proceeding to
the next riveting.
Note ەAt the time and during activation of the trigger, a small amount of air
may leak from the trigger portion. This is not a malfunction.
Note
Select a suitable size of rivet 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 “Preparation Before Use” on page 7.)
Drill a hole of appropriate size (0.1 to 0.2mm larger than the diameter
of the rivet) into the workpiece.
After inserting the mandrel (shaft) of the rivet into the nosepiece,
insert the head of the rivet into the hole.
Lightly fit the end of riveting tool to the base material. Make sure that
there is no space in the base material and other things, and then
activate the trigger.
The rivet will be installed into the workpiece.

Button fully from the "ON" marking side to start vacuuming.
㸦2㸧Insert the mandrel of rivet into the end of riveter.
ەSome rivets have mandrels with sharp ends. Be careful not to injure your
fingers on these ends.
ەIf the button is not fully pressed, vacuuming power will be lower.
Note ەIf the tank becomes over half full, cut mandrels may be
obstructed by those inside the tank and may not normally be
collected, causing them to be left in the ejection pathway.
That will result in clogging of cut mandrels and air leakage
from the Nosepiece making the unit to be unusable.
