[7] CLEANING AIR CONDITIONER FRESH/RECIRC FILTERS
• When using compressed air, there is danger of dirt flying and causing personal injury. Always
wear protective glasses, dust mask, and other protective equipment.
• Always check that the slide door is locked at the open or closed position before cleaning the
FRESH or RECIRC filter. If the slide door is free, there is danger that it may suddenly move and
catch your fingers or break the cover.
• The guide for cleaning the filter is 500 hours, but if the machine is used on an extremely dusty
jobsite, reduce the maintenance interval and clean the filter more frequently.
• When washing the floor, be careful not to get water on the air conditioner system.
