2. MAINTENANCE
AIR CLEANER
The consumer air cleaner should be serviced
every
25 hours of engine use. The commercial
air cleaner is of a two part design: the foam
pre-cleaner should be serviced every 25 hours
and the paper element every
50 hours. More
frequent service for both air cleaners may be
required in dusty or dirty conditions.

wire off the spark plug.

teaspoons of SAE 30 engine oil. Squeeze
the element

Clean the foam element with soap and
water.
DO NOT OIL THIS ELEMENT.
Clean the paper element with Air Filter
Element Cleaner, Toro part number 27-
7220. CAUTION: This compound contains
sodium metasilicate which may cause burns
and is harmful
if swallowed. Keep this
chemical
out of the reach of children.
Follow the manufacturers instructions.
Light accumulations
of dust may be re-
moved by blowing compressed air from the
inside
to the outside of the dry element.
CAUTION: Always wear safety glasses when
working with compressed air. This proce-
dure should be used if the element must be
immediately put back in service because a
washed element must be dried before use.
Make sure the compressed air is at 280 kPa
(40 psi) or less. Hold the air nozzle at least
1
inch away from the element.
After cleaning examine the paper element
for holes or leaks by holding a light behind
the element. Slowly turn the element and
look through the paper for defects.
