6. TROUBLESHOOTING
In the event of tool malfunction, perform the following five–point visual inspection of the tool before attempting
a detailed troubleshooting procedure.
1. Ensure that the air pressure is regulated at 552 kPa [80 psi] minimum to 689 kpa [100 psi] maximum.
2. Ensure that the pivot pins are fully inserted.
3. Ensure that the jaws are properly mated with the cam.
4. Ensure that the jaw cam rollers are not binding and are properly lubricated.
5. Ensure that the cam is properly lubricated.
If the five–point visual inspection does not eliminate the malfunction, refer to Paragraph 2.2, Functional
Description; Figure 8 (troubleshooting table); and Section 7, Parts List (which contains an exploded view of the
tool). If the malfunction cannot be remedied with these aids, contact TOOLING ASSISTANCE CENTER at the
