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
number at the bottom of page 1.
DANGER
To avoid personal injury or damage to the tool, ALWAYS DISCONNECT the tool from the air supply before attempting
to disassemble the tool for parts inspection or replacement.
MALFUNCTION
Jaws close too slowly or will not
bottom and complete the crimp.
Piston cam will not retract to open
jaws or retracts too slowly.
PROBABLE CAUSE
REMEDY
Insufficient air pressure.
Ensure that the air pressure is at least 552 kPa
[80 psi].
Piston O" ring is deteriorated allowing too much
blow-by."
Replace piston O" ring. Refer to Paragraph 8.2.
Air valve spool O" rings are deteriorated
allowing too much blow-by."
Replace air valve spool O" rings. Refer to
Paragraph 8.3.
Air valve spool needs to be adjusted.
Adjust air valve spool. Refer to Paragraph 8.4.
Jaw cam rollers are binding or need to be
lubricated.
Clean, inspect, and lubricate the jaw cam rollers.
Refer to Section 5.
Cam is damaged or needs to be lubricated.
Replace the cam (refer to Paragraph 8.1) or
lubricate the cam (refer to Paragraph 5.3).
Piston rod O" ring is deteriorated (air leaks into
jaw housing from behind the main piston cam).
Replace piston rod O" ring. Refer to Paragraph
8.2.
Air valve spool O" rings are deteriorated
allowing too much blow-by."
Replace air valve spool O" rings. Refer to
Paragraph 8.3.
Air valve spool needs to be adjusted.
Adjust air valve spool. Refer to Paragraph 8.4.
There is insufficient air pressure.
Figure 8
Ensure that the air pressure is at least
552 kPa [80 psi].
