after which the cartridge must be changed. Never operate
the lift truck with the air filter removed or damaged.
NOTICE
Respect the safety distance of 30mm between the air jet
and the cartridge to avoid tearing or making a hole in
the cartridge. The cartridge must not be blown
anywhere near the air filter box. Never clean the
cartridge by tapping it against a hard surface. Your eyes
must be protected during this intervention.

Do not clean the dry air filter cartridge by washing it in
liquid. Do not clean by any means the safety cartridge
located inside the filter cartridge, change it for a new one if
it is dirty or damaged.
In case of use in a heavily dust laden
atmosphere, the cartridge inspection and
cleaning frequency must be reduced.
