Air Cleaner Inner Safety Element
NOTE: For maximum engine protection and air
cleaner service life, install a new inner safety
element every third primary element change or
after every 1000 hours of operation, whichever
comes first.
The air cleaner inner safety element
④
cannot
be cleaned. It must be replaced once it becomes
partially clogged. A clogged element will cause
an air restriction resulting in a loss of engine
power or excessive black exhaust smoke.
NOTE: Conduct a visual inspection of the inner
safety element by placing a light inside the
element. Little or no light will shine through the
element if it is partially clogged.
To remove the inner safety element, pull it out of
the canister body.
To install the new element, push it into the
canister until seated.
IMPORTANT: Clean any dirt from the canister
before installing the inner safety element. Check
element inner diameter seals for damage and
replace the safety element if seal damage is
present.
IMPORTANT: Failure to obtain a good seal
between the filter and canister may cause major
engine damage.
