Unintentional sparking can result in fire
or electric shock.
WHEN ADJUSTING OR MAKING REPAIRS TO YOUR
POWER 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.
6.14 — ENGINE OIL RECOMMENDATIONS
We recommend the use of high-quality detergent oils
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 50°F (10°C) the use of SAE 30 will result in hard start-
ing.
** Above 80°F (27°C) the use of 10W30 may cause increased
oil consumption. Check oil level more frequently.
NOTE:
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.

every 8 hours of operation. Keep oil level maintained.
