Tips for Optimal Air Conditioner Usage
For Rapid Cooling
The temperature in the cab may rise 80°C and over (176°F)
when the machine is exposed to sun light in the summer.
In this case, ventilate the air in the cab first by opening the
windows for rapid cooling.
After starting the engine, set the temperature control
toward the far left end using temperature control switch (9).
Set mode switch (11) to
the right front and rear vents.
Set blower switch (8) at the slow speed position. Turn air
conditioner switch (7) ON.
After running the engine at slightly faster speed (1300 to
1400 min
-1
[rpm] or higher) for 2 to 3 minutes, increase the
air flow.
Close the window when the cab cools down to the ambient
temperature.
When Windows Become Clouded
If inside of the windows becomes clouded during rainy
season or on humid days, operate the air conditioner to aid
in keeping the windows clear.
When the atmosphere is very damp and if the air
conditioner has run excessively, outside of the windows
may become clouded. If this happens, turn OFF the air
conditioner to adjust the temperature in the cab.
Off-Season Air Conditioner Maintenance
To protect each part of the compressor from a lack of
lubricant, operate the air conditioner at least once a month
for several minutes with the engine running at a slow speed
even during off-season.
When the cab temperature is 15°C and under (59°F), the air
conditioner may not operate. If this happens, warm the cab
using the heater first.
IMPORTANT:
Do not suddenly increase the engine speed. Failure
to do so may damage the compressor.
Keep open flames away from the control panel.
Refer to the item "Clean and Replace Heater/Air
Conditioner Filter" in the Maintenance Section for
maintenance of filters.
