emove spark plug using wrench provided (Fig.18).
I
nspect spark plug for damage, and clean with a wire
b
rush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced. Make sure
electrode gap is 0.60mm-0.80mm.
NOTE: If replacing, use the following recommended
spark plug: F7RTC.
Screw spark plug back by hand, avoid damaging
t
hreads of the cylinder.
P
ut the spark plug back in position and use the spark
p
lug wrench to tighten it. If spark plug is new, use 1/2
turn to compress washer appropriate amount. If
reusing old spark plug, use 1/8 to 1/4 turn for proper
washer compression.
Replace spark plug cap.
CLEANING THE FUEL VALVE FILTER
The fuel valve filter prevents dirt and water that may
have gotten into the fuel tank from entering the
carburetor. If the engine has not been run for a long
time, the fuel valve filter should be cleaned before
use.
Turn the fuel valve to the OFF position.
Unscrew the sediment cup on the bottom of the fuel
valve (Fig.19).
Clean it with gasoline and wipe off any excess.
Check the gasket of the seal ring and replace it if it is
damaged.
Assemble everything back together after inspection
and return the fuel valve to ON position and check for
leaks.
CLEANING THE EXHAUST PORT & MUFFLER
Depending on the type of fuel used, the type and
amount of oil used, and/or your operating conditions,
the exhaust port and muffler may become blocked
with carbon deposits. If you notice a power loss with
your petrol-powered tool, you may need to remove
these deposits to restore performance. We highly
recommend that only qualified service technicians
perform this service.
CLEANING THE FUEL TANK FILTER
Remove fuel cap and filter (Fig.20).
Clean the filter, replace if broken.
Dry the filter and install back on the generator.
DRAINING THE FUEL TANK
Turn the engine switch OFF ( O ).
Close fuel valve.
Remove the fuel line from the barb by using pliers to
loosen the tubing clamp and sliding the fuel line off.
Install one end of a drain line over the barb, and place
the other end in a fuel container large enough to catch
the fuel being drained from the tank.

I
f the generator is not to be used or is to be stored for
more than one month the following storage procedure
should be carried out. Drain all the fuel from the fuel
tank and the carburettor, ensure that all the fuel has
b
een removed. Remove the spark plug and pour
approximately one tablespoon full of clean engine oil
into the spark plug hole. With the ignition turned OFF
g
ently pull on the recoil starter cord several times.
Re-fit the spark plug and continue to pull the recoil
starter cord until the piston is on the compression
stroke (when resistance is felt) then stop puling.
Store the generator in a dry well ventilated place
under a cover to prevent any dust or debris from
accumulating on the generator.
DRAINING THE CARBURETOR
Turn off fuel valve, make sure fuel is drained and the
tank is empty. Residual gasoline left over a long time
will cause difficulty when next starting the engine.
Position an approved fuel container under the
carburetor drain screw to catch fuel; loosen the screw.
(Fig.21). Allow fuel to drain completely into container.
Retighten drain screw.
After draining the fuel tank and carburetor, start the
engine and allow it to run until the unit runs out of
fuel. Consult hazardous waste management guidelines
in your area for the proper way to dispose of fuel.
Replace engine oil. The used engine oil will produce
lots of oil remnants. If the generator is not in use for a
long time, a lots of thick oil deposits may remain. The
generator components maybe damaged when used
the next time.
Check if screws and bolts are loosened. Tighten again
if necessary.
Carefully clean the gasoline generator with an oil-
dipped cloth. Spray anti-corrosion agent if necessary.
Do not clean the generator with water.
When preparing the generator for storage, follow the
guidelines below.
STORAGE TIME
Less than 1 month:
• No special preparation is needed.
1 to 2 months:
• Empty fuel from fuel tank.
2 months to 1 year:
• Empty fuel from fuel tank
• Drain fuel from carburetor.
• Clean fuel sediment cup.
