13.4 Maintenance
13.4-1 CHECKING AIR FILTERS (INTAKE VALVE)
This check should be performed periodically after every 100 hours of work. If the machine operates in severe
conditions, especially very dusty environments, it will be necessary to perform these checks on a daily basis.
COMPRESSOR AIR FILTER
Figure 13.4-1A Compressor air filter
The filter consists of two filtering elements. To check them, loosen the nut (Figure13.4-1A, (1) ) and remove
the element of the 1st stage (outer) (3). Should any traces of dust be noticed on the element of the 2nd stage
(inner) (5), remove this one also by removing the nut (4).
The filter element must never be washed with water or other substances, but it must be
replaced after every 500 hours of work.
