O–Ring Maintenance
Purchase an O–Ring Repair Kit, item 75116, at your local

This kit includes replacement o-rings and a water inlet
filter. Refer to the instruction sheet provided in the kit to
service your unit's o-rings.
WARNING The high pressure stream of water
that this equipment produces could cut
through skin and its underlying tissues,
resulting in serious injury and possible
amputation.
• NEVER repair leaking connections with sealant of any
kind. Replace o-ring or seal.

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.
* Below 40°F (4°C) the use of SAE 30 will result in hard
starting.
** Above 80°F (27°C) the use of 10W30 may cause increased
oil consumption. Check oil level more frequently.
