Cabin air filters category 4
(optional)
NOTE
Standard air filtering category 2 is obsolete if the
machine is equipped with the option cabin air
filtering category 4. Instead of the pocket filters
and activated-carbon filters, closing coverings
are installed on the cabin roof.
The filter system serves to protect the operator
in the cabin from air pollution. The ambient air is
cleaned by one or more filter stages and freed
from dust, aerosols or gases. The filter system
has an integrated fan which transports the fil -
tered fresh air into the cabin. At the same time,
a certain overpressure is generated in the cabin.
The filter system can optionally be mounted
as category 3 (without activated-carbon filter)
or category 4 (with activated-carbon filter). If
the filtration is to pass as category 3 only, the
activated-carbon filter must be removed and the
empty frame installed.
WARNING
Any maintenance work on the filter system must
only be carried out with the engine shut down.
Pay attention to possibly contaminated dust in
the filter. Do not inhale it and avoid skin contact.
Do not blow out or suction out the filter. Dispose
of filter dusts properly.
CAUTION
Safety risk from wrong spare parts!
Wrong spare parts may affect the safety and
function of the filter system and cause damages.
¾
Check the spare parts before installation
¾
Use only original spare parts of the manu-
facturer
NOTE
To generate adequate overpressure in the cab-
in, the default ventilation must also be activated
when selecting Cat 4 filtering! The fan speed of
the default ventilation must be increased in the
event of inadequate cabin overpressure. Refer
to the section Air conditioning / Heater .
