Always check out the simplest possible cause of a
malfunction first. For example, an air hose not connected.
Then proceed logically, eliminating each possible cause
until the cause is located. Where possible, substitute
known good parts for suspected bad parts. Use
Troubleshooting chart as an aid in locating and correcting
malfunction.
NOTE:
Piston Drift is when the air piston is in the down position,
but the hydraulic pull piston is not in the full forward
position. This causes an out of sequence condition.
1 Tool fails to operate when trigger is depressed.
a) Air line not connected.
b) Vent hole in air cylinder (78) is blocked.
c)
Vent hole in air valve (79) is blocked.
2 Tool does not complete fastener installation and
break pintail.
a) Air pressure too low
b) Air Piston Quad-ring (50) worn or damaged.
c) Insufficient fluid on pull side: Refer to Fill and
Bleed section.
d) Air in hydraulic system: Refer to Fill and Bleed
section.
3 Pintail stripped and/or swaged collar not ejected.
a) Check for broken or worn jaws in nose assembly:
Refer to nose assembly data sheet.
b) Insufficient fluid on return side: Refer to Fill and
Bleed section.
4
Tool has piston drift.
a) Worn or damaged Piston Assembly (31): Inspect
O-rings (33 & 35), and Back-up Rings (38).
Replace if necessary.
5
Hydraulic fluid exhausts with air or leaks at base of
handle.
a) Worn or damaged Gland Assembly (54): Inspect
Polyseal (61), O-rings (55 & 58), Quad-ring (56),
and Back-up Ring (57). Replace if necessary.
6. Hydraulic fluid leaks at rear of Pull Piston (4)
a) Worn or damaged Rear Gland (8): Inspect
O-rings (9 & 11) and Back-up Ring (10). Replace
if necessary.
7. Hydraulic fluid leaks at front of Pull Piston (4).
a) Worn or damaged front seal: Inspect Back-up
Ring (2) and O-ring (3). Replace if necessary.
8. Pull Piston (4) will not return.
a) Throttle Valve (36) stuck: Lubricate O-rings (37,
39, 55, & 80).
9. Air leaks at air Cylinder Head (49).
