During engine operation, the indicator shows the vacuum
pressure, which is specified in terms of inches of H
2
O and kPa.
As dirt accumulates in the filter, the vacuum pressure increases.
When the indicator gauge reaches the CHANGE FILTER mark (A),
25 in. of H
2
O (6.20 kPa), a warning tone will sound and the cab
display module (CDM) will indicate that the filter requires
servicing.
IMPORTANT:
Excessive servicing of the filter element increases the risk of dirt
entering the air intake system, which can cause severe engine
damage.
Service the air filter
ONLY IF
the indicator reaches the CHANGE
FILTER mark (A) or registers a reading of 25 in. H
2
O (6.20 kPa).
IMPORTANT:
After servicing the filters, press the RESET button on the end of indicator (B).
Removing Primary Air Filter
The windrower
’
s cab display module (CDM) will alert the Operator when the engine air filter requires service. The air filter
