Nozzle Maintenance
A pulsing sensation felt while squeezing the spray gun trigger
may be caused by excessive pump pressure. The principal
cause of excessive pump pressure is a nozzle clogged or

the problem, immediately clean the nozzle following these
instructions:
1. Shut off engine and turn off water supply.
2. ALWAYSpoint spray gun in a safe direction, press red
button and and squeezespray gun trigger to release
retained high water pressure.
_i, WARNING The high pressure stream of water that
this equipment produces can cut through skin

Oil
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.
