11.15 Air System
!
NOTE: Location and shape of air filter differs depending on brand and model.
The air filters consist of a filter housing (F) with cover (A), clamps (B), main cartridge (D),
safety cartridge (E), and evacuation valve (C). Air filtration is performed in two stages. The
first stage comprises a cyclone and the second stage a normal filter. Both filtration stages
take place in the filter housing. The filter performance improves right up until it becomes
clogged. Never clean the filter cartridges as this impairs filtration and also risks damaging
the filter element. There is an indicator that is on the filter housing to advise when the filter
cartridge is clogged. The indicator is connected to the display in the cab. A warning symbol
comes on in the status bar at the bottom of the display if a filter is starting to clog.
It is important to keep the air filter and air cleaner in good condition so that the exhaust
gases are as clean as possible. Repeated disassembling and assembly can damage the
gasket between the insert and the filter housing. Smoke and poor engine performance can
be an indication of clogged filters.
11.15.1 Air Filter Indicator Function
To ensure filter clogging is detected, the function of the air filter indicator must be checked
regularly. This is done by gradually covering the air intake with a piece of wood or similar.
The sensor (A) should then send a signal and the warning symbol or the warning light
should come on. If a warning is not indicated, start by checking the cable connections. If
there are no problems with the connections, then the sensor is faulty and must be re-
placed. The sensor is not included in the filter housing, but is ordered separately.
!
NOTE: Be sure to use an intact and clean piece of wood so that dirt or other particles
do not enter the filter housing.
