3.3 GENERAL RECOMMENDATIONS
The warranty of the generator does not cover items that have been
subjected to operator abuse or negligence. To receive full value
from the warranty, the operator must maintain the generator as
instructed in this manual.
Some adjustments will need to be made periodically to properly
maintain the generator.
All adjustments in the Maintenance section (3) of this manual
should be made at least once each season. Follow the requirements
in the "Maintenance Schedule" chart on page 14.
NOTICE:
Once a year you should replace the spark plug and replace the
air filter. A new spark plug and clean air filter assure proper fuel-
air mixture and help your engine run better and last longer.
3.3.1 GENERATOR MAINTENANCE
Generator maintenance consists of keeping the unit clean and dry.
Operate and store the unit in a clean dry environment where it will
not be exposed to excessive dust, dirt, moisture or any corrosive
vapors. Cooling air slots in the generator must not become clogged
with snow, leaves, or any other foreign material.
Check the cleanliness of the generator frequently and clean when
dust, dirt, oil, moisture or other foreign substances are visible on
its exterior surface.
