OPERATION
EXPLANATION OF COMPONENTS
TEMPERATURE CONTROL SWITCH
This switch (4) can be used to adjust the temperature steplessly
between low temperature and high temperature.
The temperature level indicator lamps (A) light up to display the
temperature of the air coming from the vents.
The more blue lamps on, the lower the temperature is.
The color of the indicator lamp (A) changes while the switch is
being pressed.
When the temperature reaches the desired level, release the
switch to set the temperature.
The settings for each mode are retained in memory even when the starting switch is turned OFF.
However, in the following cases, the settings must be reset.
When the machine has been out of use for more than 7 days
When the battery voltage is extremely low
When there has been abnormal interference from outside
When the fan switch is turned OFF (the setting is not kept in memory with only the air conditioner switch)
If the air conditioner is used in the FRESH position, the inside of the cab will be pressurized and this will prevent the
entry of dust.
The higher the position of the fan switch, the more effective the pressurizing becomes.
