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 at your local Sears service center.
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.
ENGINE MAINTENANCE
WARNING
Unintentional sparking can result in fire or
electric shock.
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
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.
Checking Oil Level
Oil level should be checked prior to each use or at least
every 5 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 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 on dipstick. DO NOT overfill.
4. Replace and tighten dipstick.
