140/160PH

6.6 Oil Filling

After the filling the pulse unit must be tightened to the
required torque.
1. Connect the pulse unit to the quick disconnect coupling using the
adapter <A2>.
2. Close the shut-off valve.
3. Connect air supply of approx. 5 bar.
4. Slowly open the shut-off valve fully, until the vacuum pressure
gauge shows approx. 1 mbar (-1 bar).
5. Wait for approx. 2 minutes until the number of vacuum bubbles has
decreased substantially.
6. Slowly close the shut-off valve. The pressure gauge indicates
atmospheric pressure again. Missing oil is pressed into the pulse
unit.
7. If necessary, repeat the steps 4. to 6. until no more bubbles come
out.
8. Disconnect the pulse unit, remove the adapter and add a few drops
of oil with syringe <B>.
- Install the ball <57>/<84> and tighten the set bolt <58>/<85>
(2,9 ±0,3 Nm).

Caution! Caution!
- Tighten threaded ring by the required torque (8. Assembly
instructions, fig. 7)
- Fit ball bearing <60>/<87> with the circlip <59>/ <86> into the
housing <62>/<89>. Insert the O-ring <61>/<88>. Push fully over
the long shaft end of the hydraulic rotor.
- Fit ring retaining ring <35>/<90>. Screw the whole component
onto the pistol grip.
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.
6.7 Top up Oil
- Remove set bolt <58>/<85>. Remove ball <57>/<84> by turning
the drive shaft <51>/<78>, keeping the opening away from the
body.
- Carry out oil filling, see 6.6.
