12. When there are no more bubbles in the oil, top off the hydraulic oil in the Sleeve Lower (51) to the level of the Backup
Ring (19).
13. Make sure the Jaw Guide (3) is loose (see No.7). Push the Air Piston Assembly (57) into the Sleeve Lower (51) to
the half-way point. While holding the Air Piston at the half-way point, replace the Nose Housing and hand tighten.
14. With a clean rag, wipe off any oil on the Air Piston Assembly (57), Handle Lower Assembly (54), and Sleeve Lower
(51). Put Chamber (89) over Air Piston Assembly (57) then turn the tool upright and tighten the four Socket Head
Cap Screws (88) to a Torque of 46 - 51 in-lbs (5.2 – 5.8 N-m).
15. Remove the Nose Housing (6), and tighten the Jaw Guide (3) by hand until it stops.
16. Loosen the Fill Screw (45) approximately 3 - 3½ full turns or a 0.14"(3.6mm) gap to allow excess hydraulic oil and
bubbles to escape. When no more oil comes out, tighten the Fill Screw (Fig. 7).
17. Wipe off any dirt and oil on the tool.
18. Replace the Nose Housing (6) and Collector (96).
