- Push the leaf springs <70>/<115> and the control blades <71>/
<116>, <72>/<117> into the narrow groove.
- Align the long pin end of the control blade <72>/<117> to the bore
in the hydraulic sleeve <63>/<108> (fig. 3).
- Push pin <62>/<107> and washer <61>/<106> onto the sleeve
<63>/<108>.
- Push the hydraulic cylinder <60>/<105> over the pre-assembled
parts and tighten them by hand with the bearing ring <78>/<123>
(Fig. 4).
- Turn the pulse unit over and insert it in the fixture <C1>.
- Undo the bearing ring <78>/<123> by 270°+90° and carry out the

oil filling:

6.6 Oil Filling
1. Begin by filling the impulse unit with syringe <B> by way of the
drive shaft, until oil emerges through the seal hole.
2. Assemble the compression spring <81>/<126>, bolt <82>/<127>,
ball<83>/<128>, valve screw <87>/<132> and stop washer asm.
<88>/<133>. Turn the valve screw back gently against the stop
washer asm. (protection against loss).
Caution! Caution!
The assembled stop washer must only be installed with
the fixture <H> (see Assembly instructions P1746E).
3. Connect the pulse unit using the adapter <A2> to the quick
disconnect coupling.
4. Close the shut-off valve
5. Connect pressure of about 5 bar.
6. Slowly open the shut-off valve fully, until the pressure gauge
shows a vacuum of about 1 mbar (-1 bar).
7. Wait for about 2 minutes, until the number of vacuum bubbles has
substantially reduced.
8. Slowly close the shut-off valve. The pressure gauge shows
atmospheric pressure again, and missing oil is forced into the
pulse unit.

9. Repeat steps 6 to 8, if necessary, until the number of bubbles is
negligible.
10. Disconnect the pulse unit, remove the adapter and add a few
drops of oil with syringe <B>.
11. Install the ball <79>/<124> and tighten the set bolt <80>/<125>
(1+0.3 Nm).
Caution! Caution!
12. Tighten bearing ring <78>/<123> to the required torque (8.
Assembly Instructions, Fig 5).
- Fit the ball bearing with the <92>/<137> circlip <91>/ <136> into
the housing <94>/<139>. Insert the O-ring <93>/<138>. Push fully
over the long shaft end of the hydraulic rotor.
- Fit retaining ring <89>/<134>. Screw the whole component onto
the pistol grip.
Remarks:

6.7 Refilling with Oil

- Remove retaining ring <89>/<134>, stop washer asm. <88>/<133>,
valve screw <87>/<132> and ball <83>/<128>.
Caution! Caution!
- Knock out bolt <82>/<127> and compression spring <81>/<126>.
- Remove set bolt <80>/<125>. Remove ball <79>/<124> by turning
the drive shaft <73>/<118>, keeping the opening away from the
body.
- Undo bearing ring <78>/<123> by 270° +90°.
- Carry out oil filling, see 6.6.

The bearing ring <78>/<123> must not turn along!
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.
The assembled stop washer must only be removed with
the fixture <H> (see Assembly instructions P1746E).
