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 of this manual should 
be made at least once each season. Follow the requirements in the 
"Maintenance Schedule" chart.
NOTE:
Once a year, replace the spark plug and replace the air filter. A 
new spark plug and clean air filter assure proper fuel-air mixture 
and help the 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.
  Never insert any object or tool through the air 
cooling slots, even if the engine is not running.
