Right Side of Machine (1) Charge filter (2) S O S tap (3) Charge bypass switchCharge filter (1) is located under the operator platform, on the right side of the machine.Charge oil from the fan hydraulic system flows through charge filter (1). This oil is directed from the filter to the following locations:
Vibratory pump
Propel pump
Machine valveThe housing of the charge filter contains a bypass valve. If the pressure differential across the filter is greater than 280 kPa (41 psi), charge bypass switch (3) closes. When this situation happens, the machine ECM number one logs a level 2 fault and flashes an amber light on the operator display in order to alert the operator of a clogged filter. If the pressure differential across the filter is greater than 350 kPa (51 psi), the bypass valve opens. When the bypass valve opens, charge oil flows directly to the pumps and shift valve. S O S tap (2) provides a means of obtaining oil samples upstream of the charge filter.

Front of Machine (4) Cooling packageCooling package (4) is located at the front of the machine. The hydraulic oil cooler is contained within the cooling package.The return manifold (not shown) combines the case drain oil from the propel pump, vibratory pump, the vibratory motors, and the propel motors. Oil from the return manifold is directed into the inlet port of the hydraulic oil cooler. The outlet port of the hydraulic oil cooler is connected to the hydraulic tank.

Rear of Machine (5) Rear back-up alarmRear back-up alarm (5) is located at the rear of the machine, behind the water tank.The engine ECM controls the signal to the rear back-up alarm (5). The machine ECM number one sends a back-up alarm request to the engine ECM through the CAN lines when the propel lever is in the reverse range.Note: The front back-up alarm (not shown) is identical and located on the front of the machine. When the operator station is facing the rear of the machine, the front back-up alarm is activated when the propel lever is in the reverse range.

Operator Seat (6) Seat position switch "2" (7) Seat position switch "1"The optional seat position switches are located at the base of the operator seat. A removable panel provides access to these components. The seat position switches are proximity switches.The machine ECM number one monitors the state of seat position switch "2" (6) and seat position switch "1" (7) in order to determine the position of the operator seat.When seat position switch "1" (7) is closed and seat position switch "2" (6) is open, the machine ECM number one determines that the operator seat is facing forward. When seat position switch "1" is open and seat position switch "2" is closed, the machine ECM number one determines that the operator seat is facing rearward.When both seat position switches are closed, the machine ECM number one determines that the operator seat is in a transitional position. When this situation happens, the
