Maintenance
21. Move the intensifier (item 76) up approximately ½ inch more. This will force air trapped at the top of the
ram sleeve into the upper bore chamber of the handle, in front of the hydraulic piston.
22. Let the tool stand for approximately 2 minutes so that any air in the upper bore chamber rises towards the
fill screw.
23. Move the intensifier up so that the pulling head is in the full back position. Apply pressure to the bottom of
the air piston and loosen the fill screw until oil seeps by the threads of the fill screw. Continue until the
piston gap setting is .180 (4.6mm). See gap setting.
24. Tighten fill screw to 60-65 in – lbs.
25. Wipe away any excess oil from the handle.
26. Inspect Ram Seal (92) for cuts and defects. Inspect inside
surface of the Ram Sleeve (84) for marks and scratches.
27. Reinstall the intensifier chamber and sleeve (78 & 79) and
O-ring (93 & 58).
28. Install the Clamp assemblies (11, 12, 89, 90 and 94). Be sure
that the orientation of the clamps is correct. Tighten both Clamp
Nuts (94) to 8 – 10 in–lbs. NOTE: The orientation of the words
“Made In U.S.A.” on one of the clamps should be the same as the
words “POP” on the Handle (4) and located opposite the air inlet port
of the Handle.
29. Reinstall the Nose Housing Assembly (101 / 102).
