Oil Recommendations
NOTE:
Use a high quality detergent oil classified “For Service
SF, SG, SH, SJ” or higher. DO NOT use special additives.
1.
Choose a viscosity according to the table below:
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.
SAE 30:
40°F and higher (5°C and higher)
is good for all
purpose use above 40°F, use below 40°F will cause hard
starting.
10W-30:
0 to 100°F (-18 to 38°C)
is better for varying
temperature conditions. This viscosity improves cold weather
starting, but may increase oil consumption above 80°F
(27°C).
*Check oil level frequently at higher temperatures.
Synthetic 5W-30:
-20 to 120°F (-30 to 40 °C)
provides the
best protection at all temperatures as well as improved
starting with less oil consumption.
5W-30:
40°F and below (5°C and below)
is recommended for
winter use and works best in cold conditions.
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.

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.
WARNING
The high pressure stream of water that this
equipment produces can cut through 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.
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 NOTcheck for spark with spark plug removed.
NOTICE
Overfilling with oil may 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.
