Inspection and lubrication of pulse unit

Make sure that the
O-ring's groove is clean
To fill the pulse unit with oil
Due to a possible microleakage of oil from the pulse unit, it could be necessary to refill the
unit between the regular overhaul intervals. The frequency of this procedure depends on
the type of application, number of cycles, tightening time etc. An indication of not enough
oil is a decreased tightening torque and an increased pulse frequency. (See "Test after ser-
vice")
After disassembly of pulse unit, fill with oil according to operation No. 1-3 below. Run
the machine in a vice for 10 seconds according to operation No. 5 below. Then continue
according to operation No. 6-11. For best performance use Hydraulic Oil 22 cST/40° C
(ISO VG22).
Oil : 22 cSt / 40 ˚C (ISO VG22)
