REVERSIBLE FAN
The Reversible Fan is a hydraulically-
driven constant pitch fan. Fan speed is
controlled based on cooling demand. A signal
is sent to the Hydraulic Valve Block
(mounted on the side of the fan assembly),
which controls the speed and direction of the
fan.
To Activate the Reversible Fan
Refer to “Machine Display” provided in
the
Cab Section
elsewhere in this manual for
complete operating instructions.
Before Starting the Engine
1. Ensure all hoses and wires are ade-
quately secured and routed away from
the fan operating area.
2. Ensure all tools have been removed from
the engine compartment, including the
top side of the radiator and inside of the
shroud before the fan guards are
installed. Obstacles in the path of rota-
tion can interfere with movement of the
fan and can result in damage to the fan
blades, fan hub, and radiator core.
3. Inspect the radiator shroud mounting
bolts to ensure that the radiator and
shroud are firmly secured and unable to
move during operation of the machine.
