3.1 PERFORMING SCHEDULED MAINTENANCE
It is important to perform service as specified in the Maintenance
Schedulefor proper generator operation, and to ensure that the
generatorcomplies with the applicableemission standardsfor the
durationof its useful life. Service and repairsmay be performed by
any capableperson 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 MaintenanceSchedule.
3.2 MAINTENANCE S CHEDULE
Follow the calendar intervals. More frequent service is required
when operatingin adverseconditions noted below.
CheckOilLevel At EachUse
Change Oil $ *Every100 hoursor EverySeason
Check ValveClearance ***Every Season
Service Air Filter ** Every200 hoursor EverySeason
Replace SparkPlug EverySeason
$ Changeoil after first 30 hours of operation then every season.
* Changeoil and oil filter every month when operating under heavy load or in high
temperatures.
** Clean more often under dirty or dusty operating conditions. Replaceair 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 HIGHALTITUDE OPERATION
Thefuel system on this generatormay be influencedby operation
at higher altitudes. Proper operation can be ensured by installing
an altitude kit when required. See the table below to determine
when an altitudekit is required.Operatingthis generatorwithout 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.

be madeat least once eachseason. Followthe requirementsin the
"MaintenanceSchedule".
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
