Selective Control Valves (SCV), Mechanical - Pressure Settings for Series 450

LX1045796-UN-22DEC10

A - Lock Function

B - Flow Control Valve

C - Plug

NOTE: All selective control valves are factory adjusted to switch off at a pressure of 18000 kPa (180 bar; 2610 psi).

If the selective control valve in lock function switches off too early (control lever goes into neutral position too early), or if it switches off too late or not at all (control lever goes into neutral position too late or not at all), proceed as follows:

1. Disconnect hydraulic hoses at the connectors (if equipped).

2. Engage the lock function (A) (as far as it will go to the right) and move flow control valve (B) to the mid-position.

3. Take out plug (C) and insert a 1.5 mm (0.06 in.) hex socket wrench.

4. Start the engine and turn the screw clockwise as far as it will go.

5. Move control lever of the SCV to the raise or lower position (the control lever remains in the raise or lower position).

6. Turn the screw counterclockwise until the control lever returns to neutral position.

   NOTE: One full turn changes the pressure by approx. 2000 kPa (20 bar) (290 psi).

7. Re-install the plug.
