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 50 hours or 6 months after. To replace engine oil;
1) Open rear access panel, then loosen and remove the oil gauge dipstick (A) Fig.9.
2) Screw the oil drain pipe (B) into the oil gauge dipstick opening.
3) Tilt the generator forward and drain the oil from the engine.
4) Once all the oil has completely drained, remove oil drain pipe.
Recommended Engine Oil
It is recommended to use SAE 10W30 4-stroke gasoline engine oil. For cold weather
(below -15ºC) use SAE 5W30.
5) Using the supplied oil fill container, pour 0.45L (450ml) of clean engine oil through the
oil gauge dipstick opening, 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 (A7RTC or equivalent)
The spark plug should be checked every 50 hours of operation or every 6 months. To
replace or clean spark plug;
1) Open the top spark plug access cover.
2) Dismantle the spark plug cap (A) Fig.10 by pulling it off the spark plug. Using the
supplied spark plug wrench, undo the spark plug by turning it counterclockwise.
3) 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.
4) 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
with an A7RTC or equivalent (NGK BPR6ES, Champion Z8YC).
5) Reinstall spark plug in the reverse order.
Fuel Filter Maintenance
If the fuel filter become clogged, it will need to be replaced. To do this, it is necessary to drain
all gasoline from the tank and the carburetor, see section “Generator Storage” below for
complete instructions. Once the tank and carburetor are drained of all gasoline, disconnect
the fuel hoses from the fuel filter (B) Fig.12 and replace it. Reinstall all parts in the reverse
order.
Muffler Spark Arrester Screen Maintenance
An uncleaned muffler spark arrester screen will produce louder noise levels and it will
affect the engine running. If using this generator in dusty and dirty conditions, the muffler
spark arrester screen (A) Fig.12 must be cleaned to prevent clogging of the exhaust
fumes. To clean muffler spark arrester screen;
1) Make sure the generator is not running and has cooled down.
2) Undo the 6 pan head screws (B) Fig.12 and remove the muffler cover (C).
3) Undo the 2 pan head screws (D) which secure the muffler spark arrester screen (A) to
the muffler (E) and remove the spark arrester screen.
4) Inspect the spark arrester screen, remove it from the holder and clean with a metalic
brush if it is necessary. If it is too difficult to clean, replace it.
