Maintenance-Standard Cleaner. Under ordinary conditions
where the truck is driven on hard surface roads, the air cleaner
should be serviced every 2,000 miles.
Under extremely dusty conditions,
often encountered on gravel or dirt
roads, the air cleaner should be serv-
iced at more frequent intervals.
Servicing is accomplished by re-
moving the cover wing nut, the cover
and the filter element (fig. 29). Slush
the filter element in cleaning solvent
until all foreign matter
is
r emoved,

cleaner reservoir should be checked at regular intervals and
sufficient S.A.E. 50 oil added
