2. Remove screwed
¿ ttings on the coupling.
3. Remove couplings and underlying seals
4. Position the new coupling, together with the seals, onto the valve block.
5. Re-attach the couplings with the bolts and tighten to a torque of M
A
= 40 Nm.
6. The hydraulic
À uid tank must be re¿ lled and the power unit vented.
3. Loosen the union nuts on the hose lines and remove the coupling.
Procedure for coupling to hose pairs:
