CLEAN AIR CONDITIONER FRESH/RECIRC FILTERS

If compressed air scattered around dust and debris, there is danger of injury. Always wear protective equipment such as
protective glasses and mask.
NOTICE
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.
Cleaning Recirculated Air Filter
1. Roll up floor mat (1) on the front left part of the floor in the
operator's cab, and open cover (2).
2. Take out internal filter (3).
3. Clean internal filter (3) with compressed air. If there is oil stuck
to the filter or it is extremely dirty, wash it in a neutral agent.
After washing, dry it thoroughly before using it again.
REMARK
If the clogging of the filter cannot be removed by blowing it with
compressed air or washing in water, replace the filter with a new
one.
4. Install cleaned filter (3), close cover (2) and spread floor mat (1)
flat.
