Fig. 12 To fill the pulse unit with oil
Operation No. 1 – 10 (after disassembly of pulse unit)
Due to a possible microleagage of oil from the pulse unit, it could
be necessary for 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. A indication of
too little oil is decreased torque and increased pulse frequency.
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. 4. Then continue according to
operation No. 5 – 10.
Oil : 22 cSt / 40 ˚C (ISO VG22)
