Change engine oil
NOTICE
Change engine oil when the engine is warm.
1. Place the pressure washer on a flat level surface.
2. Turn off the engine
3. Place an oil pan under the drain oil port.
4. Clean the oil gauge dipstick/cap and the area
around it to ensure that no dirt falls into the
crankcase.
5. Turn the oil gauge dipstick/cap counterclockwise,
remove it and clean it with a clean cloth.
6. Remove the hexagon head drain plug, allow the oil
to drain completely.
7. Reinstall the hexagon head drain plug.
8. Add engine oil into the crankcase through the oil
gauge dipstick/cap installation port (a fuel funnel
may be needed here). Do not overfill.
9. Fully reinsert the oil gauge dipstick and pull it out to
check the oil level.
MAX
MIN
10. If the oil level is just at MIN marker or below, refill
SAE 10W-30 oil through the dipstick hole until the
oil level is between MIN and MAX marker.
11. Reposition the oil gauge dipstick and tighten it by
turning clockwise.
Spark plug
Starting failure and misfiring are often caused by a
fouled spark plug. Clean the spark plug and check that
the plug gap is in the correct range. For a replacement
plug, use the correct type.
1. Disconnect the spark plug wire by pulling it off the
spark plug.
2. Using the spark plug wrench, remove the spark
plug by turning counterclockwise.
3. Check spark plug condition for fouling, worn and
rounded center electrode.
4. Check to see if there is carbon sediment build-up, if
so, remove it. If the carbon sediment is excessive,
replace the spark plug.
