FAN ROTATION DIRECTION CONTROL SYSTEM
(Optional)
The radiator, oil cooler and intercooler cores are cleaned by
rotating the fan in reverse.
1. Return control lever (1) to neutral while running the
engine. Pull pilot control shut-off lever (2) to the LOCK
position as illustrated.
2. Turn off the air conditioner.
IMPORTANT: • Unless pilot control shut-off lever (2) is
in the LOCK position, the fan rotation
direction control system can not be
activated.
• If the fan rotation direction is changed
while operating the air conditioner,
damage to the air conditioner may result.
• Before changing the fan rotation direction,
check that objects are not present on the
upperstructure that can be drawn into the
fan.
3. Pull the armrest up and press fan rotation direction
selector (3). Then, the fan rotation direction control
system is automatically activated in the following order.
1) When fan rotation direction selector (3) is pressed, the
engine speed is reduced to slow idle.
2) The fan rotation direction is reversed approximately
20 seconds after the engine speed is reduced to slow
idle.
3) The engine speed is resumed to the speed set by the
engine control dial approximately 5 seconds after
the fan rotation direction is reversed. At this time, the
fan speed is also changed together with the engine
speed change.
IMPORTANT: • When the engine is running at slow
idle, the fan speed is maintained at the
minimum. As the engine speed increases,
the fan speed increases.
• When required to increase the fan speed,
increase the engine speed by operating
the engine control dial.
4) The fan continues to run in reverse for approximately
60 seconds in this state.
5) Approximately 60 seconds later, the engine speed is
reduced to slow idle.
6) The fan rotation direction is returned to normal
approximately 20 seconds after the engine speed is
reduced to slow idle.
7) The engine speed is recovered to the speed set by
the engine control dial approximately 5 seconds
after the fan rotation direction is returned to normal,
completing fan rotation direction control operation.
