The system for ride control acts as a shock absorber by absorbing forces from the bucket. Absorbing the forces from the bucket stabilizes the entire machine.Note: The load control valves will not function properly on a machine with a manifold for the ride control.Note: The manifold for the ride control will not function properly on a machine with the load control valves.

(11) Ride Control SwitchPush the top of the switch in order to turn on the ride control system. The ride control will smooth the ride of the machine during travel. Return the switch to the central position in order to turn off the system for ride control. Push in the bottom of the switch in order to turn on the automatic ride control. Return the switch to the central position in order to turn off the automatic system for ride control.The ride control switch (11) controls the solenoid in solenoid valve (3) and solenoid valve (9). The ride control switch will have three positions. The three positions are ON, OFF, and AUTO.Turn ride control switch (11) to the OFF position. The functions of the machine are identical to a machine without ride control. When the ride control is turned off, solenoid valve (3) and solenoid valve (9) de-energize. The check valve (7) blocks the flow of oil from the rod ends of the lift cylinders to the tank. The solenoid valve (3) blocks the flow of oil from the accumulator (1) to the head end of the lift cylinders (5). This also forces oil to flow through orifice (2). Orifice (2) is in the passage from the head end of lift cylinders (5) to the ride control accumulator (1). The orifice (2) in the line to the accumulator prevents the rapid loss of oil which is stored in accumulator (1) when the loader arms are lowered. Orifice (2) also allows the accumulator to be charged without affecting machine performance when the loader arms are lifted.Turn ride control switch (11) to the ON position. The lift cylinders are allowed to move up and down when the ride control system is in the ON position. When the ride control is activated, solenoid valve (3) and solenoid valve (9 ) shift. Any downward force that is placed on the lift arms is transferred to the hydraulic fluid at the head end of lift cylinders (5). As the lift cylinders retract, oil is displaced from the head end of the cylinders and flows through solenoid valve (3) and into accumulator (1). Oil is then drawn from the tank into the rod ends of the cylinders. Accumulator (1) acts as a shock absorber when the cylinders retract. This provides a smoother ride.
