IMPORTANT: • Do not operate the pilot control shut-
off lever and/or the key switch while
activating the fan rotation direction
control system, damage to the operating
equipment may result.
• As soon as any abnormality or danger is
detected, stop the engine.
• The appropriate hydraulic oil temperature
on this machine is from 50 to 80 °C. If the
machine is operated when the hydraulic
oil temperature is lower than this range,
damage to the hydraulic components may
result. Before activating the fan rotation
direction control system, sufficiently
perform warm-up operation to preheat
hydraulic oil.
• When the fan is rotating in reverse,
the radiator and the oil cooler are not
normally cooled. Before activating the
fan rotation direction control system,
check that the coolant temperature gauge
needle is within the recommended range
as illustrated to the right.
• Do not activate the fan rotation direction
control system when the coolant
temperature gauge needle is outside the
recommended range.
Action to be Taken When the Coolant Temperature Gauge
Needle is Outside the Recommended Range
1. Cool coolant temperature by reducing the engine speed
to slow idle until the coolant temperature is lowered to
the recommended range.
2. After checking that the coolant temperature gauge
needle has entered the recommended range, take
action by following the procedure designated for the fan
rotation direction control system operation.
IMPORTANT: • If any warning mark such as overheating
are displayed on the monitor during
reverse fan rotation operation, move pilot
control shut-off lever (1) to the UNLOCK
position. Thereby, the fan rotation
direction control system is deactivated so
that normal fan rotation is resumed.
• If any warning mark is detected, refer to
the warning occurrence display on the
monitor screen and take the appropriate
measures.
