4. Turn power OFF and clean dust and dirt
from motor, tank, air lines and pump
cooling fins.
NOTE: The air filter in the filter housing on
the side of the head must be checked and
cleaned periodically, more often if used
under very dusty conditions or when a
great deal of fog from spraying is allowed
to circulate near unit.
IMPORTANT: Unit should be located as
far from spraying area as hose will allow
to prevent over-spray from clogging filter.
FILTER REMOVAL, INSPECTION AND
REPLACEMENT
To change a filter, pull off the filter
housing cover. If filter element is dirty,
rotate filter cover so the holes line up with
clean element material and snap cover
onto housing. If filter element has no
clean areas, replace element or entire
filter.

This is an oilless type compressor requiring
no lubrication.
