Replacing The Air Filter; Kohler Engine - Husqvarna Z4219 Operator's Manual

Replacing the Air Filter

If the engine seems weak or runs unevenly, the air
filter may be clogged. If the machine is run with a
dirty air filter, the spark plug can become fouled. It
is important to replace the air filter regularly (see
"Maintenance Schedule" for proper service intervals).

Kohler Engine

The standard engine is not equipped with a prefilter.
As an option, a prefilter can be installed on the inside
of the air filter cover.
1. Loosen the two retaining knobs and remove
the cover. If the engine has a prefilter, it is
mounted on the inside of the cover.
2. Clean the area around the filter element to
prevent debris from getting into the engine
when the element is removed.
3. Remove the filter element. Replace a dirty,
bent or damaged element with a new one.
Handle the new element carefully and do
not use if the sealing surfaces are bent or
damaged. If the element can be reused, tap it
against a solid surface to remove dust.
4. Check the air cleaner base. Make sure it is
secured and not bent or damaged. Also check
the air filter cover for damage or improper fit.
Replace all damaged air cleaner components.
5. Install the filter element. Check that it fits
properly and that no air leaks occur.
6. Install the cover and tighten knobs by hand.
IMPORTANT INFORMATION
Operating the engine with loose or
damaged air cleaner components could
allow unfiltered air into the engine causing
premature wear and failure.
IMPORTANT INFORMATION
Do not use compressed air to clean the air
filter.
Filter should be assembled dry and not be
oiled.
