| Hydraulic Oil Pressure (Main Relief Valve Set Pressure) Boom, Arm Adjusting Method | 1. Loosen locknut (2), then begin adjusting pressure by turning setting screw (1). Turning clockwise raises the set pressure. Turning counterclockwise .... lowers the set pressure. 2. In order to keep the setting screw from turning after pressure has been adjusted, tighten the locknut while at the same time holding the setting screw firmly in place. 3. Operate the relief valve once more to confirm that the pressure that has been set it stabilized. | p. 43 |
