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.13.
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 SAE 10W30 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, fill then check oil level until
the oil level reaches 3/4 up the dipstick or until it reaches the bottom lip of the dipstick hole.
Inspecting, Replacing or Cleaning Spark Plug (F7TC or equivalent)
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.14 by pulling it off the spark plug (B). Using the
supplied spark plug wrench, undo the spark plug by turning it 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.15. The spark plug electrode clearance
should be between 0.7-0.8mm. If the clearance exceeds 0.8mm, replace the spark plug
with an LD F7TC or equivalent (NGK BP6ES, Champion N9Y).
4) Reinstall spark plug in the reverse order.
Fuel Filter Maintenance
In order to clean the fuel filter inside the fuel shut-off valve, it is necessary to drain all
gasoline from the tank and the carburetor, see section "Generator Storage" below for
complete instructions.
1) Once the tank and carburetor are drained of all gasoline, disconnect the fuel hose (A)
Fig.16 from the fuel shut-off valve and then dismantle the fuel shut-off valve nut (B) from
the tank.
2) Remove the fuel shut-off valve from the tank to expose the fuel filter (C). Clean the fuel filter.
3) Reinstall all parts 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 gasoline:
3) Turn fuel shut-off valve (A) Fig.17 to the "OFF" position.
4) Disconnect the fuel hose (B) from the fuel shut-off valve.
5) Turn fuel shut-off valve to the "ON" position and drain fuel from tank. Pivot the fuel
shut-off valve outwards to simplify the task as shown in Fig.17.
6) Remove drain hex. bolt (D) from the carburetor (C) and drain the rest of the fuel found
inside the carburetor and hose.
7) Reposition the carburetor drain hex. bolt and fuel shut-off valve hose 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.
