Service Air Cleaner

A dual element air cleaner is standard. A dirty primary
element is indicated when the air restriction indicator on
instrument panel illuminates. A dirty element can result in
loss of power or excessive smoke.
IMPORTANT: Check unloader valve (B) frequently.
Empty as often as needed to keep it
from filling with dust. If valve is allowed
to fill with dust, air cleaner element will
plug rapidly.
Service air cleaner (A) when indicator light illuminates,
every 250 hours or at least once a year.
Replace primary element at least one a year.
The secondary element should be removed only when
being replaced, normally once a year.
