Information included in the Service Manual: Technical information needed for redelivery and delivery, operation and activation of all devices and systems, operational performance tests, and troubleshooting procedures.

Information included in the Workshop Manual: Technical information needed for maintenance and repair of the machine, tools and devices needed for maintenance and repair, maintenance standards, and removal / installation and assemble / disassemble procedures.

Reverse Rotation:
1. When the fan reverse rotation switch is turned ON, the fan reverse rotation control solenoid valve (6) shifts by signals from the MC. (Refer to SYSTEM/Control System.)
2. Pressure oil from port P is routed to the end of the fan reverse rotation spool (2) through spool (8) of the fan reverse rotation control solenoid valve (6).
3. Therefore, fan reverse rotation spool (2) moves to the right (left on the circuit diagram).
4. Pressure oil from port P flows to the fan motor through the periphery of the fan reverse rotation spool (2) and port B.
5. Therefore, the fan rotates in reverse direction.
