ENGINE MAINTENANCE
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.13. Place an oil pan underneath drain hex. bolt (B), remove hex. bolt (B) and drain
oil. Once all the oil has completely drained, retighten the hex. bolt (B).
Recommended Engine Oil
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.14 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 just 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 F6TC, you can replace it with an NGK BP6ES spark plug or
equivalent.
4) Reinstall spark plug in the reverse order.
PUMP MAINTENANCE
Pump Oil Replacement
Pump oil should be annually replaced with approx. 4.7 fl. oz. (138ml) of SAE 300 non detergent oil.
To replace pump oil, undo oil bolt (A) Fig.15, and drain pump oil. Once oil has completely drained,
fill with recommended oil. Retighten oil bolt.
Pressure Washer Storage
If you plan on storing your pressure washer for an extended period of time, the following steps
should be followed;
1) Add fuel stabilizer to fuel tank to minimize the formation of fuel gum deposits during storage.
2) Run engine at least 5 minutes after adding stabilizer to allow it to enter the fuel system.
NOTE: If a fuel stabilizer is not used, all gasoline must be drained from the tank and carburetor to
prevent gum deposits from forming on these parts and causing possible malfunction of the engine.
3) Turn fuel shut-off valve to the "OFF" position, remove drain hex. bolt (A) Fig.16 from the
carburetor (B).
4) Now turn fuel shut-off valve to the "ON" position and drain the fuel from the tank, carburetor and
hose.
5) Reposition the carburetor drain hex. bolt once the fuel is completely drained.
6) Drain engine oil from engine as described in "Engine Oil Replacement".
7) Pour approximately one teaspoon of engine oil through the spark plug hole and pull the recoil
starter slowly until you feel increased pressure which indicates the piston is on its compression
stroke and leave it in this position. This closes both the intake and exhaust valves to prevent the
inside of the cylinder from rusting.
8) Cover the pressure washer and store it in a clean, well ventilated and dry place.
Preventing Freezing Damage
If your pressure washer is subjected to freezing temperatures, damage could occur.This type of
damage is not covered under warranty. To avoid possible damage, a small amount of antifreeze
can be used. Place the unit on its side with the water inlet facing upwards, pour 1/4 cup of antifreeze
into the water inlet. Disconnect spark plug wire, then pull recoil starter several times to circulate the
antifreeze in the pump system. Reconnect spark plug wire. It is also important to make sure the wand
and all hoses are disconnected and drained of all water or they may burst. When taking pressure
washer out of storage, run water through the system until it runs clear.
