Engine Oil Replacement
Engine oil should be replaced after the first 20 hours of operation or
after the first month of use, it should be replaced every 100 hours or 6
months after. To replace engine oil; loosen the oil gauge dipstick (A)
Fig.16. Lean the pressure washer and drain oil. Once all the oil has
completely drained, retighten the oil gauge dipstick (A).

It is recommended to use SAE10W30 4-stroke gasoline engine oil. Fill
with clean engine oil through the oil gauge dipstick hole to recommended level.
Inspecting, Replacing or Cleaning Spark Plug
The spark plug should be checked every 100 hours of operation or every 6 months.
To replace or clean spark plug;
1) Dismantle the spark plug wire (A) Fig.17 by pulling it off the spark plug (B). Using
the supplied spark plug wrench, undo the spark plug by turning counterclockwise.
2) Check to see if there is carbon sediment build-up, if so remove it. If the carbon
sediment is excessive, replace the spark plug.
3) Measure the electrodes clearance using a feeler gauge. The spark plug
electrode clearance should be between 0.7-0.8mm. If the clearance exceeds
0.8mm, replace the spark plug. The original spark plug supplied is an LD F7TC,
you can replace it with an NGK BP6ES spark plug or equivalent.
4) Reinstall spark plug in the reverse order.
