NOTE: Once a year you should clean or replace the spark
plug, clean or replace the air filter, and check the spray gun
and nozzle extension assembly for wear. A new spark plug
and clean air filter assure proper fuel-air mixture and help
your engine run better and last longer.
Pump Oil
DO NOT attempt any oil maintenance on this pump. The
pump is pre-lubricated and sealed from the factory, requiring
no additional maintenance for the life of the pump.

Maintenance, replacement, or repair of the emissions
control devices and systems may be performed by any
non-road engine repair establishment or individual.
However, to obtain "no charge" emissions control service,
the work must be performed by a factory authorized dealer.
See the Emissions Warranty.
