Refer to Special Instruction, REHS5464, "Accumulator Discharging and Charging Procedures" for the required tooling, and the testing and charging procedure.Nitrogen Charging Procedure
Refer to Special Instruction, REHS5464, "Accumulator Discharging and Charging Procedures" for the required tooling, and the testing and charging procedure.Testing the Ride Control Diverter Valve
The following procedure is used to determine whether the check valve for the rod end of the lift cylinders is operating correctly. Perform this test after the ride control accumulator is charged.
Start the machine.
Press ride control button (1) to turn off the ride control system.
Place the bucket in the full DUMP position. Lift the front wheels off the ground by moving the lift control lever to the LOWER position.
When the front wheels are off the ground, place the lift control lever in the HOLD position. In approximately 5 seconds, press and hold ride control button (1) for 2 seconds to turn on the ride control system. Two indicators should be illuminated. The front wheels should lower to the ground.If the wheels do not lower to the ground, the diverter spool has not shifted to the ON position.
