3-3 Cleaning and Replacing the Air Filter
Air is circulated in the controller of the base machine to cool the controller. The cooling air is
introduced through the air filter on the rear of the Front cover machine. Dust may be accumulated choking the
air filter which decreases the cooling power causing serious damage such as thermal breakdown of ICs if the air filter is not properly maintained. Clean the air filter once every six months. If the air filter is heavily clogged, replace the air filter.
1.Turn off the POWER switch and unplug the power cord from an electrical outlet.
2.Remove the front cover.
