1. Prefill the pulse unit with ESSO UNIVIS J26 using the injection
syringe <B>.
2. Connect the pulse unit to the quick-action coupling using the
adapter <A2>.
3. Close the shut-off cock.
4. Connect supply pressure of approx. 5 bar.
5. Slowly open shut-off cock, until the pressure gauge shows a
vacuum pressure of approx. 1 mbar (-1 bar).
6. Wait for approx. 2 minutes, until the number of vacuum bubbles
has decreased substantially.
7. Carefully close the shut-off cock. The pressure gauge again
shows atmospheric pressure, missing oil is forced into the pulse
unit.
8. Repeat steps 5 to 7 if necessary, until no more bubbles form.
-
Decouple the pulse unit, unscrew the adapter and top up with a
few drops of oil from the injection syringe <B>.
-
Fasten plug screw <88> (5+1 Nm).
Caution!
Caution!
The bearing ring <56> must not turn with the plug screw!
-
Pull needle roller <63> and fill the shut-off chamber behind it using
the injection syringe <B>, be sure there are no bubbles.
-
Reinstall needle roller <63>.
-
Tighten bearing ring <56> to the required torque (8. Assembly
Notes, fig. 16).
-
Install ball bearing <90> in housing <92>. Insert O-ring <91>.

Install equalizing washer <89> to hydraulic cylinder <86>.
-
Screw housing <92> onto pistol grip housing <1> and tighten it
using a strap wrench.
Remarks:
Small bubbles appearing at high vacuum pressure in the
wetting layer between the oil and the material are not
indicating leakage of the pulse unit. The filling result will
not be affected thereby.
