Engine air cleaner (4)
The function of the engine air cleaner is to filter
the air taken into the engine through the engine’s
air intake. The engine air cleaner is the dry type
with two elements: a primary element that is
cleanable and replacable, and a safety element
that should only be replaced and not cleaned.
The assembly also include a dust vacuator valve
and an air cleaner indicator.
Cleaning / replaciing the dust vacuator valve
Discharge the dust by pressing together the upper part of the valve.
Cleaning / replacing the air filter car-
tridge
NOTE:
Air intake filter pollution depends on the dust con-
tent in the air and the mesh size of the filter select-
ed.
The maintenance of the filter becomes necessary
if:
- The restriction gauge reads 25” H
2
O when the
engine is stopped. This indicates that a restric-
tion has occured. This usually means the filters
are dirty and requires opening the air cleaner
and cleaning or replacing the elements.
- When the engine electronic unit indicates serv-
ice required.
Never leave the air cleaner open longer than necessary!
