Check and Replace the Air Filters
Check
The air cleaner assembly is equipped with an air filter
restriction indicator (1). When the service indicator
window is red, air flow through the filter is restricted and
the primary air filter element must be replaced. Reset the
air filter restriction indicator after servicing by pressing the
end of the indicator body.
Replace the secondary air filter every 500 hours.
The dust valve (4) is at the bottom of the end cover (3).
When the engine is off, the dust valve should be closed.
NOTE:
If the dust valve is cracked, torn, remains
open, or is missing, dust particles that are
normally expelled can reenter the filter
housing and deposit themselves on the filter,
shortening the air filter service life.
NOTICE!
If you check or replace air filter elements when the engine is running, dirt may enter the
engine and cause damage. It is necessary to shut off the engine before conducting this
procedure.
