PRL650-6S 4. Preparation for use (1) Make sure that Nosepiece that suits the rivets used are attached: If incompatible parts are attached, replace them with those specified to suit the rivets used (see Table 2-2 on P. 4). (See P.14 for Replacing Nosepiece.) (2) Attach the coupler (AN500-72) to R-Joint block of rivet tool, to supply compressed air.
Page 9: ５．Precautions For Use
PRL650-6S 5. Precautions for use (1) Air pressure used Use the rivet tool with an air pressure of 0.5-0.6 MPa. If the specified air pressure is exceeded, the tool could break, resulting in an accident or injury. If the air pressure is lower than that specified, it may not be possible to setting rivets.

PRL650-6S 7. Maintenance and Inspections (Table 7.1) Item Purpose ･Maintains proper Jaws operation and extends the service life. Spraying lubricant into the Jaws ･To remove metal particles and prevent slippage of Jaws or being caught Cleaning the tip parts ･To prevent early wear on Jaws and Jaws case ･To remove metal particles and prevent slippage of Jaws or being caught...
Page 13 PRL650-6S 7-3. Greasing the Jaw case When Jaws slipping or catching occurs earlier in the spraying lublicant into the Jaws, grease inside of Jaw case. Catching: After a rivet is setting, the jaw is caught by the jaw case and does not open, and the mandrel cannot be ejected.
Page 14 PRL650-6S 7-4. Exchange of Hydraulic oil When hydraulic oil is down and the stroke is low (one trigger operation does not allow riveting), exchange the hydraulic oil by the following procedure: If stroke is low immediately after hydraulic oil is exchanged, seal has worn: Ask for repair.
Page 15 PRL650-6S (7) Loosen Fill screw about 3mm, push and hold Air piston. The hydraulic oil oozes out from Fill screw, and hold it, until this polluted hydraulic oil does not come out. (Fig. 7-9) (8) Pull out Air piston assembly, inject the hydraulic oil again according to (4), and tighten Fill screw temporarily.
Page 16 PRL650-6S 7-5. Replacing Nosepiece Use the specified Nosepiece to match the rivets used (see Table 2-2 on P.6). If Nosepiece is damaged, replace it. ＜Procedure＞ (1) Use spanner to remove Nosepiece from Nose housing. (Fig. 7-12) Remove Nose housing Nosepiece Fig.
Page 17 PRL650-6S ＜Procedure＞ (1) Cut off supply of compressed air by separating the coupler. (2) Remove Collector. Collector lock nut is held by the hand, turn Collector in the left, and remove it. (Fig. 7-13) Collector lock nut Remove Collector Fig. 7-13 (3) Remove Collector lock nut and Valve shutter.
