General Recommendations
Regular maintenance will improve the performance and
extend the life of the pressure washer. See any qualified
dealer for service.
The pressure washer's warranty 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 pressure washer as instructed in this manual,
including proper storage as detailed in Winter Storage and
Long Term Storage.
NOTICE Should you have questions about replacing
components on your pressure washer, please call
(877) 224-0458 for assistance.
Some adjustments will need to be made periodically to
properly maintain your pressure washer.

All service and adjustments should be made at least once
each season. Follow the requirements in the Maintenance
Schedule chart above.
NOTICE 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.
Emissions Control
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.

2. Clean debris.
3. Check water inlet screen for damage.
4. Check high pressure hose for leaks.
