Engine Oil Replacement (Oil capacity: 0.6 Liters)
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;
1) Unscrew and remove the oil gauge dipstick (A) Fig.12.
2) Place an oil pan underneath drain hex. bolt (B), remove hex. bolt (B) and drain oil.
3) 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. For cold weather (below
-15ºC) use SAE 5W30.
4) Fill with clean engine oil through the oil gauge dipstick hole, fully reinsert the oil gauge
dipstick and pull it out to check the oil level.
5) If the oil level is close to the "L" (low mark), refill with SAE 10W30 oil through the dipstick
hole until the oil level reaches "H" (high mark) on the dipstick.
6) Reposition the oil gauge dipstick and tighten it by turning clockwise.
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 cap (A) Fig.13 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. See Fig.14. The spark plug electrode clearance
should be between 0.7-0.8mm. If the clearance exceeds 0.8mm, replace the spark plug.
4) Reinstall spark plug in the reverse order.
Fuel Filter Maintenance
1) Set the fuel shut-off valve lever (A) Fig.10 to the left "Off" position, and dismantle the fuel
filter cup (A) Fig.15 attached to the caburetor by turning it counterclockwise.
2) Remove the fuel filter inside, clean both the fuel filter and the cup. If the rubber seal
between the fuel filter and fuel filter cup seems damaged, replace it.
3) Reinstall all parts in the reverse order.
Water pump Storage
If you plan on storing your water pump 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.
Run engine at least 5 minutes after adding stabilizer to allow it to enter the fuel system.
2) Drain all the water from the pump housing before storing, this can be done by undoing
the drain cap at the bottom of the pump housing.
3) Remove the spark plug, add about 2-3 cc of engine oil into the cylinder and reinstall spark
plug. Pull the recoil starter handle until resistance is felt. Now both inlet and outlet valves
are closed to prevent the engine chamber from rusting.
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.
4) Turn fuel shut-off valve lever to the left "Off" position. Remove the fuel filter cup (A) Fig.15.
5) Turn fuel shut-off valve lever to the right "On" position and drain fuel from tank.
6) Turn fuel shut-off valve to the left "Off" position, remove drain hex. bolt (A) Fig.15 from the carburetor (B) and drain the remaining fuel inside
the carburetor and hose.
7) Reposition the carburetor drain hex. bolt once the fuel is completely drained.
8) Drain engine oil from engine as described in "Engine Oil Replacement".
9) Pull the recoil starter handle gently until resistance is felt.
