The filter is accessed under the machine.A back pressure check valve is located on the inlet side of the base for the hydraulic oil filter. The back pressure valve reduces cavitation in the cylinders.A check valve for the cooler bypass is located in the outlet side of the filter. The check valve provides oil to the oil cooler until enough pressure is achieved in order to bypass the oil cooler. If the oil bypasses the cooler, the oil goes to the tank. The check valve for the cooler bypass protects the oil cooler from high pressure spikes. If equipped, the filter assembly also has return ports for the ride control valve, the return for the hammer and the AWS valve.
