Cleaning / replacing the dust vacuator valve
Never leave the air cleaner open longer than necessary!
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 replaceable, and a safety
element that should only be replaced and not
cleaned. The assembly also includes a dust
vacuator valve and an air cleaner indicator
NOTE:
Air intake filter pollution depends on the dust
con- tent in the air and the mesh size of the filter
selected.
The maintenance of the filter becomes
necessary if:
- The restriction gauge reads 25” H2O when
the engine is stopped. This indicates that a
restriction has occurred. 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
service required.
