Maintenance of dry type air filter
(Vehicle with Euro II engine)
Dry type air filter with an inbuilt
cyclonic vane type pre-cleaner is
fitted. For vehicles operating under
normal conditions evacuator valve
(of air filter) is required to be
checked once every 2,000 km. This
should be done more often, if
vehicle operates in dusty conditions,
viz. off highway operation, mining
areas, construction sites, etc.
While reassembling, care must be
taken to ensure that evacuator valve
is assembled in the bottom most
position and slit opening is pointing
towards ground.
When service indicator glows, on
instrument panel. Clean air filter
housing and primary cartridge.

cartridge
a)

blink take your vehicle to nearest
Tata authorised workshop.

cartridge. Replace it after three
changes of primary cartridge or
