5.
Tighten the tool studs firmly to seat the tool piston fully into the tool cylinder and against
the end cap.
Do not use any type of impact tool.
6.
Verify the tool plunger is seated firmly against the stop.
The tool plunger must be seated against the stop in order to fully seat the tool
piston within the tool cylinder.
7.
Before proceeding, turn each of the tool studs counter-clockwise 3/4 turn.
Failure to back the tool studs out 3/4 turn could make tool removal difficult and
possibly result in damage.
8.
Use a 3/4-inch (19 mm) socket and ratchet to rotate the tool plunger clockwise until a
gauge pressure of 21,750 psi (1,500 bar) is achieved.
9.
Loosen the end cap, hex nuts two full turns. Use a 15/16-inch (24 mm) combination
wrench if necessary.
Do not back them against the tool studs or they will seize together when pressure is
removed from the tool.
