Air Filter; Kohler Engine - 20 Hp - Husqvarna RZ4219 Operator's Manual

MAINTENANCE
Air Filter
If the engine seems weak or runs unevenly, the air
filter may be clogged. If running with a dirty air filter,
the spark plugs can become fouled.
For this reason, it is important to replace the air filter
regularly (see the heading Maintenance Schedule for
the proper service interval).
WARNING!
The engine and the exhaust system
become very hot during operation.
Risk for burns if touched.
Allow engine and exhaust system to
cool at least two (2) minutes.

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.
