3.1 PERFORMING SCHEDULED MAINTENANCE
It is important to perform service as specified in the Maintenance
Schedule for proper generator operation, and to ensure that the
generator complies with the applicable emission standards for the
duration of its useful life. Service and repairs may be performed by
any capable person or repair shop. Additionally, emissions critical
maintenance must be performed as scheduled in order for the
Emissions Warranty to be valid. Emissions critical maintenance
consists of servicing the air filter and spark plugs in accordance
with the Maintenance Schedule.
3.2 MAINTENANCE SCHEDULE
Follow the calendar intervals. More frequent service is required
when operating in adverse conditions noted below.
Check Oil Level At Each Use
Change Oil ‡ *Every 100 hours or Every Season
Check Valve Clearance ***Every Season
Service Air Filter ** Every 200 hours or Every Season
Replace Spark Plug Every Season
‡ Change oil after first 30 hours of operation then every season.
* Change oil and oil filter every month when operating under heavy load or in high
temperatures.
** Clean more often under dirty or dusty operating conditions. Replace air filter
parts if they cannot be adequately cleaned.
*** Check valve clearance and adjust if necessary after first 50 hours of
operation and every 100 hours thereafter.

3.3.3 HIGH ALTITUDE OPERATION
The fuel system on this generator may be influenced by operation
at higher altitudes. Proper operation can be ensured by installing
an altitude kit when required. See the table below to determine
when an altitude kit is required. Operating this generator without the
proper altitude kit installed may increase the engine’s emissions
and decrease fuel economy and performance. Kits may be
obtained from any Dealer, and should be installed by a qualified
individual.

** At elevations above 8000 ft, the engine may experience decreased
performance
3.4 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".
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.
3.4.1 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.
