Clean the air filters.
Remove the dust from the air filters by vacuuming or washing them. After washing, allow the air filters to dry
thoroughly in an area protected from sunlight.
NOTES
• Dust can be cleaned from the air filter either with a vacuum cleaner, or by washing the filter in a solution of mild deter-
gent and warm water. If you wash the filter, be sure to allow it to dry thoroughly in a shady place before reinstalling.
• If dirt is allowed to accumulate on the air filter, air flow will be reduced, lowering operating efficiency and increasing
noise.
• During periods of normal use, the air filters should be cleaned every two months.
