IMPORTANT. TOOL MUST BE DISCONNECTED FROM THE AIR SUPPLY. USE ONLY APPROVED HYDRAULIC OIL
SPECIFIED IN THIS MANUAL.
1. Disconnect tool from air supply.
2. Remove Nose Housing Assembly (101 or 102).
3. Loosen fill screw (67) together with fill screw washer (63) ¼” turn.
4. Remove clamp screws (89 & 90), clamp nuts (94), right and left
clamps (11 & 12). Note the orientation of Clamp lettering “Made In U.S.A.”.
5. Remove intensifier chamber and sleeve (78 & 79), Remove O-ring (93
& 58). To avoid spilling hydraulic oil, DO NOT remove Intensifier Assembly
(76) at this time.
6. Turn tool upside down as shown in View E1. Slowly withdraw the
intensifier assembly (76), being careful not to scratch or score the
inside of the Ram Sleeve surface (84).
7. Turn the tool right side up over a pan that can capture the hydraulic oil
as it is drained from the tool. The oil will exit the tool out of the Ram
Sleeve (84).
8. Remove or loosen the fill screw Assembly (67 & 63). Allow oil to drain
for a minute or two.
9. Invert the handle, pulling head down (view E1) in a soft jawed vise. Grip the tool gently on the aluminum
casting in the middle of the tool handle grip area.
10. If fill screw (67) and fill screw washer (63) have been removed during dismantling, reinstall these before
proceeding and tighten hand tight (approximately 15 in – lbs).
11. Move the pulling head (40 or 41) to the full forward position. Note:
rotating the pulling head adaptor while moving it will reduce sudden
uncontrolled movement.
12. Fill ram sleeve (84) with hydraulic oil until level with the top of the
ram sleeve.
13. Slowly move the pulling head back, about ½ inch. Then, slowly
return the pulling head to the full forward position. Note: rotating the
pulling head adaptor while moving it will reduce sudden uncontrolled
movement.
14. Refill ram sleeve (84) with hydraulic oil until level with the top of the
ram sleeve. Repeat above procedure a second time.
15. With the pulling head in full forward position, refill ram sleeve, if
needed, with hydraulic fluid until level with the top of the ram sleeve.
16. Slowly move the pulling head back until the oil level in the ram
sleeve drops to approximately ½ inch for top of seal sleeve.
17. Add hydraulic fluid until level with the top of the ram sleeve.
18. Install the intensifier assembly (76) into the ram sleeve. Push in until
it is about 1/3 down.
19. Reposition this assembly to the upright position, as shown on view E2.
20. Let the tool stand for approximately 2 minutes so that any air in the ram sleeve rises to the top.
