Fan Reverse Rotation Switch
Fan reverse rotation switch (1) reverses the hydraulic driven
fan. If the radiator is clogged, rotate the hydraulic driven fan in
reverse direction to blow out the clogged dust. Carry out the
fan reverse rotation regularly to prevent the cooling system
from clogging.
Manual Operation
IMPORTANT:
Fan rotating direction can be changed during the
engine is running. Each time the ON side of fan
reverse rotation switch (1) is pressed, the fan's
rotating direction switches alternatively. While
switching the fan rotating direction, fan reverse
rotation indicator (2) flashes. When the fan rotates
in reverse direction, indicator (2) stays ON. When
fan reverse rotation switch (1) is pressed while fan
reverse rotation indicator (2) turns ON, indicator
(2) starts flashing. When the fan rotates in normal
direction, fan reverse rotation indicator (2) goes OFF.
Do not press fan reverse rotation switch (1) during
indicator (2) is flashing.
Always operate the switch while applying the
parking brake. When the parking brake is released,
the fan reverse condition is automatically canceled
after 1 minute. If abnormal situation occurs such as
engine coolant overheating, reverse rotation may
forcibly be released, or fan reverse rotation switch
may be disabled.
1. Close the side cover and the rear grille before operating
the switch.
2. Start the engine. Be sure to confirm that the parking
brake is applied. Press ON side of fan reverse rotation
switch (1) once. Fan reverse rotation indicator (2) starts
flashing. Approximately 1 minute later, the fan rotates in
reverse direction, and fan reverse rotation indicator (2)
stays ON.
3. After operation, press fan reverse rotation switch (1)
again to return the fan rotation to the normal direction.
