CHANGING/ADDING OIL (FIG. 17)
Change the oil according to the Recommended Maintenance Sched-
ule on page 17. Change the oil when the engine is warm to allow for
complete drainage. Change oil more often if operating under heavy
load or high ambient temperatures. It is also necessary to drain the
oil from the crankcase if it has become contaminated with water
or dirt. The oil capacity of the pressure washer engine is 20.3 fl oz
(600mL). Add oil when the oil level is low. For proper type of oil
refer to the “add oil” portion of the “Preparation” section.
To change oil, follow the steps below:
1. Shut off engine. Clean the area around the oil fill cap/dipstick to keep out debris then remove oil dipstick.
2. Place an oil pan on the ground to catch oil. Remove oil plug then tilt pressure washer back and to the side to
empty out the oil from the crankcase.
3. Once oil is completely drained, return the pressure washer to a level position and install the oil drain plug. Refill
the engine with new oil as instructed earlier in this manual under Adding/Checking Oil.
AIR FILTER MAINTENANCE
Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally check that the air
filter is free of excessive dirt. Refer to Recommended Maintenance Schedule.
1. Unscrew the cover bolt, then remove the air filter cover.
2. Remove the air filter element from the casing.
3. Check and clean the air filter element. Replace with a new one if the element is damaged. A good element can be
washed in soapy water and dried. Saturate the element with clean engine oil and squeeze off excess oil.
4. Re-install the element. Wipe off excess oil from the air filter housing. A small amount of oil in the element is
normal and necessary for the engine to work properly.
5. Reinstall the air filter element and cover.
CAUTION! Running the engine with a dirty, damaged, or missing air filter element will cause the engine to wear out
prematurely.
