Manual Operation; Hydraulic Coupler Switch (Option) - Hitachi ZW 550-6 Operator's Manual

Manual Operation

IMPORTANT:
 Fan rotating direction can be manually changed
when 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) while indicator (2) is
flashing.
 Always operate the switch while parked
with the parking brake. When the parking
brake is released, the fan reverse condition is
automatically canceled after 1 minute. In case
abnormal situation occurs such as engine coolant
overheating, reverse rotation may forcibly be
stopped, 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)
should start 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.
