Make sure both male and female parts are clean and free of debris; see Figure 4 for fitting
configuration. Hold female part securely when tightening so as to prevent damage to adjacent
tubing. If fitting leaks, first try retightening as needed. If leaking continues then disassemble
and check for scratches or debris on the seating conical surfaces. Clean as required. Replace
plastic caps when finished with tooling.
7.2 Pump
The pump kit is shipped full of hydraulic oil. The pump reservoir cap is sealed for shipment. To
use turn cap to the vent position. To prevent oil spillage close cap when not in use, during
storage and shipment. Lost oil should be replaced with Enerpac Hydraulic Oil. ISO 32. Mineral
Oil may be substituted, if necessary.
7.3 Bleeding Hydraulic System
Follow the tensioner assembly instructions of Section 8.0
TO AVOID FAILURE, ENSURE SAFETY AND PROPER OPERATION THE TENSIONER ASSEMBLY
MUST BE MOUNTED ON THE STUD BEFORE BLEEDING THE SYSTEM AND TENSIONING BEGINS.
The tensioner has four ports see Fig. 3, one for pressurizing, two for bleeding the system and a
fourth pressure relief port. To facilitate bleeding, start by first mounting the tensioner at the 9
o’clock stud position, which will critically place the bleed ports in their uppermost position. In
addition, make sure that the pump is always situated below the tensioner assembly.
The puller tool is equipped with 5/8” [16 mm] hex coned stem bleeder fittings installed in the
bleeder ports. With these two fittings loosened simultaneously, stroke the pump repeatedly
until the streams of oil exiting the tool from each port are free of air, then retighten the fittings.
Note:
The hose is stiff; use of this tooling can be simplified by temporarily mounting the puller
tool on one stud prior to final tightening of fittings. This will reduce the tendency for the
fittings to loosen during use.

8.1 Handling of the Tensioner
Note:
Before threading the puller screw into the stud, carefully check the cleanliness of both
the stud's and the puller screw's conical threads. Apply a light coat of clean turbine oil or a
