Push the Air Piston assembly in and move it back and forth slowly by hand five or six times
(Figure 7-19), then pull it back out again. Check the oil level. If the oil level has fallen or air
bubbles are present, let the air settle out and repeat steps (g) and (h).
h) After replacement of the hydraulic oil, line up the Air Piston assembly and the tube insertion
hole in the handle lower and push the tube into place (Figure 7-20).
i) Pass the Tube into the tube insertion holes in the Air Piston assembly and the Handle
Lower (Figure 7-21).
j) Replace the Air Chamber and the four (4) truss machine screws on the Air Chamber.
k) Turn the tool over so that the fill screw is uppermost. Use a straight screwdriver to unscrew
the fill screw to let any excess oil and air (bubbles) escape. Once the hydraulic oil stops
coming out, tighten the fill screw (Figure 7-22).
l) Finally, adjust the setting stroke correctly for desired POP Nut (Refer to the “Stroke
Adjustment” section).
