(1) S O S tap
(2) Charge bypass switch
(3) Charge filterCharge filter (3) is located under the operator platform, on the right side of the machine.Charge oil from the fan hydraulic system flows through charge filter (3). 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 (2) closes. This action causes the machine ECM to log a level 2 fault. Also, an amber LED on the operator display flashes 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 (1) provides a means of obtaining oil samples upstream of the charge filter.

(4) Cooling packageCooling package (4) is located on the right side 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 main hydraulic 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.

(5) Return manifoldReturn manifold (5) is located under the pump stack, inside the engine compartment. The rear compartment cover provides access to this component.The ports of return manifold (5) are marked for identification. The ports receive return oil from hydraulic components as follows:
Port"A" - Vibratory pump case drain
Port"C" - Rear propel motor and rear vibratory motor case drain
Port"D" - Front vibratory motor case drain
Port"E" - Front propel motor case drainReturn manifold (5) directs the combined return oil to the hydraulic oil cooler through port"B". The hydraulic oil temperature sensor is installed in the return manifold.

Rear of Machine
(6) Back-up alarmBack-up alarm (6) is located at the rear of the machine, behind the water tank.The engine ECM controls the signal to back-up alarm (6). The machine ECM sends a back-up alarm request to the engine ECM through the CAN lines when the propel lever is in the reverse range.A second identical back-up alarm (not shown) may be mounted at the front of the machine. When the operator station is facing the rear of the machine, this back-up alarm is activated when the propel lever is in the reverse range.Note: When the optional 360 degree operator station is installed and facing rearward, the new"front" of the machine is recognized. The propel lever, back-up alarm, and turn signals operate accordingly.

Operator Seat
(7) Seat position switch "1"
(8) Seat position switch "2"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
