* If the Nosepiece is damaged, replace it with a new one.
* If you change the rivet size, replace with an applicable Nosepiece.
Turn o󰀨 air supply.
Remove the Nosepiece from the Frame
Head using a wrench or spanner.
Firmly set a Nosepiece applicable to the rivet size to the Frame Head
* Please check periodically whether there is any slack of a nosepiece during work.
* If you work after the nosepiece is loosened, damage to the parts may occur.
* When riveting φ4.0/4.8 blind rivets, replace the nose piece and use the guide pipe unit 2.4-3.2.
Replace with guide pipe collar 4.0-4.8.

１To remove the oil retaining screw and the seal washer, loosen the oil
retaining screw with a hexagonal bar wrench (4 mm between opposite
sides) or the like, with the air riveter placed horizontally so that the oil
retaining screw is to the upper side.
* When you loosen the oil retaining screw, hydraulic oil may spew
vigorously. Therefore, loosen the oil retaining screw slowly at rst.
* Hydraulic oil coming from the air riveter may be black. This is not
abnormal. As long as hydraulic oil is not mixed with air, metal powder,
or dust, you can use it without a problem.
* When a large amount of air mixes with hydraulic oil, the seal can wear.
In such case, have the air riveter serviced.
⚠CAUTION
●Customers themselves do not need to oil the air riveter in principle. To lubricate parts, however, use the B29624
oiler (syringe unit, optionally available), and lubricate parts with Ebi-brand hydraulic oil B10012 (optionally
available) as explained in the following steps. If the stroke is inadequate immediately after lubricating with
hydraulic oil, the seal may be worn or some other issue may exist. In such case, have the air riveter serviced.
●Prevent oils such as hydraulic oil, lubricating oil, and grease from contacting skin and eyes. This may cause
irritation. If contacted, wash completely from the contacted area.
●Do not lubricate the air riveter with the cylinder cup removed.
* Note that hydraulic oil does not come standard with an oiler.

３Attach the oiler containing the hydraulic oil to the oiling port in
the air riveter (the part to which the oil retaining screw was attached).
* Make sure that the seal washer is attached to the tip of the oiler.
Without a seal washer in place, air can mix with the hydraulic oil
during oiling or prevent oil from being suf󳞛ciently supplied.
* If air (in the form of air bubbles) is found inside the oiler,
point the tip of the oiler upward and slowly insert the plunger to purge air,
and then attach the oiler to the air riveter.
* When you purge air from the oiler, hydraulic oil may spew from the tip of the oiler.
Keep your face away and cover the tip of the oiler with cloth or the like while purging.
* Be careful not to allow a gap to form between the oiler and the air riveter.
Gapping may allow air to mix with the hydraulic oil.

⚠CAUTION
●Do not lubricate the air riveter with the frame head nut and frame head removed.
Doing so may result in an improper amount of hydraulic oil and cause trouble with the air riveter.

⚠WARNING
●Do not oil the air riveter in ways other than that described in this instruction manual.
