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 can pierce skin and its
underlying tissues, leading to 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 every 50 hours or once yearly, whichever
occurs first.
NOTE: You must purchase an approved bottle of
pump oil by calling 1-800-4-MY-HOME (469-4663) or
online at www.sears.com.
Change pump oil as follows:
1. Drain engine oil and fuel from pressure washer.
2. Use a 8mm allen wrench to remove black pump
oil cap between high pressure outlet and garden
hose inlet.
3. Tilt pressure washer to drain oil into an approved
container until it drips slowly from pump.
4. Tilt pressure washer in opposite direction and
empty premeasured pump oil bottle into same
opening (a small funnel may be helpful).
5. Install black pump oil cap and tighten firmly.
6. Set pressure washer in upright position. Add fuel
and engine oil.

Oil Recommendations
NOTE: When adding oil to the engine crankcase, use
only high quality detergent oil rated with API service
classification SF, SG, SH, SJ or higher. DO NOT use
special additives.
1. Choose a viscosity according to the following table:
°F -20
°C -30
STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Synthetic oil meeting ILSAC GF-2, API
Oil Cap 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.
* The use of multi-viscosity oils (5W-30, 10W-30, etc.)
in temperatures above 40°F (4°C) will result in higher
than normal oil consumption. When using a multi-
viscosity oil, check oil more frequently.
** If using SAE 30 oil in temperatures below 40°F
(4°C), it will result in hard starting and possible engine
bore damage due to inadequate lubrication.
