! IMPORTANT. TOOL MUST BE DISCONNECTED FROM THE AIR SUPPLY. USE ONLY APPROVED
HYDRAULIC OIL SPECIFIED IN THIS MANUAL.
1. Disconnect from air supply.
2. Remove Nose Housing (6) and Collector (96).
3. Remove four Socket Head Cap Screws (88) using 4mm Hex-Key wrench (accessory). (Fig. 1)
4. Turn tool upside down and remove Chamber (89).
Then pull out Air Piston Assembly (57). (Fig. 2)

6. Clean the dirt off the Air Piston Assembly (57) and inner
Chamber (89) with a clean rag.
Apply a thin layer of Seal Lube to inner Chamber.
7. Loosen Jaw Guide (3) approximately 3 full turns or a 0.12"
(3mm) gap and loosen Fill Screw (45) approximately 3 - 3½ full
turns or a 0.14"(3.6mm) gap (Fig. 3).
8. Secure the tool upside down again and pour hydraulic oil into
Sleeve Lower (51) to the level of the Backup Ring (white part)
(19). (Fig. 4)
9. Push Air Piston Assembly (57) into Sleeve Lower (51) to
half-way point so that dirty hydraulic oil and air bubbles will
come out from the loosened Fill Screw (45).
Hold Air Piston Assembly until no more oil or bubbles come out.

10. Loosely tighten Fill Screw (45) and pull out Air Piston Assembly
(57).
11. Pour more hydraulic oil into Sleeve Lower (51) to the level of the
Backup Ri
ng and push Air Piston Assembly (57) into Sleeve
Lower (51). Push Air Piston inwards then outwards 5-6 times in
a slow, constant motion.
Then pull it out and check for bubbles rising to the oil surface.
If there are still bubbles, repeat the procedure until there are no
more bubbles (Fig. 6).
It may be necessary to repeat this procedure 2-3 times to bleed all bubbles from the oil.
If after 3 attempts there are still bubbles in the oil, go back to No.5 and start again by draining the hydraulic oil.
