Maintaining your generator
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;
1) Loosen the oil gauge dipstick (A) Fig.9.
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, check oil level using the oil
gauge dipstick, fill until the oil level reaches 3/4 up the dipstick.
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.10 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.11. 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 to the “OFF” position, and dismantle the fuel cock assembly
(A) Fig.12 from the fuel tank by undoing the fuel cock hex. nut (B) with an open ended key.
2) Slide the fuel cock assembly out of the fuel tank as shown in Fig.12. Unscrew and
remove the fuel filter (C), clean it and reinstall it.
3) Reinstall the fuel cock assembly in the reverse order.
Generator Storage
If you plan on storing your generator 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. To drain fuel from fuel tank and carburetor;
1) Turn fuel shut-off valve to the “OFF” position. Remove the rubber hose (D) Fig.12 from
the carburetor.
2) Turn fuel shut-off valve to the “ON” position and drain fuel from tank out from the rubber
hose into an adequate fuel container. Reposition the rubber hose onto the carburetor.
3) Unscrew drain screw (A) Fig.13 from the carburetor (B) and drain the rest of the fuel
inside the carburetor from drain hole (C).
4) Retighten the drain screw once the fuel is completely drained.
5) Drain engine oil from engine as described in “Engine Oil Replacement”.
6) Pull the recoil starter handle gently until resistance is felt.
