When using the air conditioner for a long time,
open the window once every one hour.
Be careful not to overcool the cab.
The cab is properly cooled if the operator feels
cool when entering there from outside(About
5˚C lower than the outside temperature).
When cooling, change air occasionally.
CHECK DURING SEASON
Ask the service center for replenishment of the
refrigerant or other maintenance service so that
the cooling performance is not damaged.
CHECK DURING OFF-SEASON
Operate the air conditioner 2 or 3 times a month
(Each for a few minutes) to avoid loss of oil film in
the compressor.
