O–Ring Maintenance
Purchase an O–Ring Repair Kit, item 7175116, at your local
Sears or by calling 1-800-4-MY-HOME (469-4663) or online at
www.sears.com. It is not included with the pressure washer.
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.
Pump Maintenance
Changing Pump Oil
Change oil after first 50 hours of operation and then every
200 hours or 3 months, whichever occurs first.
NOTICE When changing pump oil, use only high quality
nondetergent 30 weight oil. Use no special additives.
Change pump oil as follows:
1. Clean area around brass oil drain plug at bottom of
pump.
2. Remove oil drain plug. Drain oil completely into an
approved container.
3. When oil has completely drained, install oil drain plug
and tighten firmly.
4. Clean area around pump oil dipstick. Remove dipstick
and fill pump with recommended oil to "Full" mark on
dipstick (typically 0.35L or 12 oz.).
5. Install pump oil dipstick.
6. Wipe up any spilled oil.
ENGINE MAINTENANCE
WARNING Unintentional sparking could cause fire or
electric shock resulting in death or
serious injury.
WHEN ADJUSTING OR MAKING REPAIRS TO YOUR PRESSURE
WASHER
• Disconnect the spark plug wire from the spark plug and place
the wire where it cannot contact spark plug.
WHEN TESTING FOR ENGINE SPARK
• Use approved spark plug tester.
• DO NOT check for spark with spark plug removed.
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.
NOTICE Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with
"SJ/CF ENERGY CONSERVING" or higher, is an
acceptable oil at all temperatures. Use of synthetic oil
does not alter required oil change intervals.
