Frame leveling cylinder (1) is attached to the machine frame. Cylinder rod (2) is attached to the front axle. When the frame leveling cylinder extends, the machine will tilt to the left. When the frame leveling cylinder retracts, the machine will tilt to the right.
Both sides of cylinder (1) are closed by load control valve (3) when the control switch is in the HOLD position. If the oil supply to the cylinder fails for any reason, both sides of cylinder (1) are closed by load control valve (3).

Frame leveling cylinder (1) is controlled by control valve (4) which is operated by switch (5) on the dash panel. The control valve is spring centered. The control valve is directly operated by two solenoids. The frame leveling control is a three-position switch.
The frame leveling control is used to level the machine when the machine is on an uneven surface. The frame leveling control can cause the frame to tilt to the left or to the right. The maximum amount of tilt is 10 degrees in either of these directions.
Lower the boom before you use the frame leveling control. The boom must be close to the ground.
Press the right side of the switch for the frame leveling control in order to lower the right side of the frame. The frame rotates clockwise in relation to the axles.
Press the left side of the switch for the frame leveling control in order to lower the left side of the frame. The frame rotates counterclockwise in relation to the axles.
When the switch for the frame leveling control is released, the frame leveling control returns to the HOLD position.
