General Recommendations
Regular maintenance will improve the performance and
extend the life of the pressure washer. See any authorized
dealer for service.
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 Emissions Warranty.
The emissions control system for carbureted engines is
EM (Engine Modifications). The emissions control systems
for engines with electronic fuel injection are ECM (Engine
Control Module), MPI (Multi Port Injection), and if equipped
an O2S (Oxygen Sensor).
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.

Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF,
SG, SH, SJ or higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity
for the engine. Use the chart to select the best viscosity for
the outdoor temperature range expected. Engines on most
outdoor power equipment operate well with 5W30 Synthetic
oil. For equipment operated in hot temperatures, Vanguard®
15W50 Synthetic oil provides the best protection.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°F) the use of 10W30 may cause increased oil
consumption. Check oil level more frequently.
