O–Ring Maintenance
Purchase an O–Ring Repair Kit 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, rubber washer and 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.

electric shock resulting in death or

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

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.
Checking Oil Level
Oil level should be checked prior to each use or at least every
8 hours of operation. Keep oil level maintained.
1. Make sure pressure washer is on a level surface.
2. Remove oil dipstick and wipe dipstick with clean cloth.
Replace and tighten dipstick. Remove and and check oil
level.
3. Verify oil is at FULL mark (top hole) on dipstick. Replace
and tighten dipstick.
Adding Engine Oil
1. Make sure pressure washer is on a level surface.
2. Check oil level as described in Checking Oil Level.
3. If needed, slowly pour oil into oil fill opening to the Full
mark (top hole) on dipstick. DO NOT overfill.
NOTICE Overfilling with oil could cause the engine to not
start, or hard starting.
• DO NOT overfill.
• If over the FULL mark on dipstick, drain oil to reduce oil level to
FULL mark on dipstick.
4. Replace and tighten dipstick.
Changing Engine Oil
If you are using your pressure washer under extremely dirty
or dusty conditions, or in extremely hot weather, change oil
more often.
CAUTION Avoid prolonged or repeated skin contact
with used motor oil.
• Used motor oil has been shown to cause skin cancer in certain
laboratory animals.
• Thoroughly wash exposed areas with soap and water.
KEEP OUT OF REACH OF CHILDREN. DON'T
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.
Change oil while engine is still warm from running, as
follows:
1. Drain fuel tank by running pressure washer until fuel
tank is empty.
2. Disconnect spark plug wire and keep it away from spark
plug.
3. Clean area around oil fill, remove oil fill cap/dipstick.
Wipe dipstick clean.
