Selective Control Valves - Disconnect Hydraulic Hoses

LX266990-UN-10OCT16

CAUTION: Risk of injury due to unintended movements of hydraulic components.

When working on pressurized hydraulic components, there is a great risk that pressurized oil can eject and/or that unintended movements of the implement are triggered.

To avoid this, the implement must be lowered to the ground before disconnecting hydraulic hoses. The hoses and leads need to be depressurized and the controls of the valves need to be blocked in neutral position.

1. Lower implement to ground.

2. Switch off the engine and engage the park lock.

3. With the ignition on*, bring the selective control valves several times into the "Extend" and "Retract" positions.

   * Ignition is only necessary with electrically actuated multi-function valves, e.g. the electric multi-function lever.

4. Activate the transport lock or detent the corresponding lever in neutral position.

   • Bring the SCV control lever into the neutral position and lock with the levers (A).

5. IMPORTANT: Do not apply force when disconnecting the hoses. Pull hoses in a straight line out of connections, without jamming. This can otherwise cause damage to the couplers.

   Pull hoses straight out from couplers.
