Spark Plug
Check the spark plug for dirt and grime; if necessary
clean it with a copper wire brush.
First time after approximately 10 hours of
operation
Hereafter service the spark plug after every 50
hours of operation.
How to:
Disconnect the spark plug cap, and remove
any dirt from around the spark plug area.
Remove the spark plug with a spark plug
wrench. Inspect the spark plug.
Replace it if the electrodes are worn, or if the
insulator is cracked or chipped.
Measure the spark plug electrode gap with a
suitable gauge.
The gap should be 0.70 - 0.80 m. Correct the
gap, if necessary, by carefully bending the side
electrode.
Mount the spark plug carefully, by hand, to
avoid cross-threading.
After the spark plug seats, tighten with a spark
plug wrench to compress the water. If
reattaching a used spark plug, tighten 1/8 - 1/4
turn after the spark plug seats. If installing a
new spark plug, tighten 1/2 turn after the spark
plug seats.
Attach the spark plug cap.
Notice: An incorrect spark plug can cause engine
damage.

STORAGE

Proper preparation for long term storage is essential
for keeping your snow blower free from rust corrosion
and prevent part and function to parts impair. The
following steps will make the engine easier to start
after storage and prevent your snow blower from
rusting during long term storage.
Notice: The warranty does not cover damage on
machine or engine as a result of incorrect storage or
negligence to comply with maintenance
recommendation and warning.
Cleaning If the engine has been running, allow it to
cool for at least half an hour before cleaning. Clean all
exterior surfaces, seal up any damaged paint, and coat
other areas that may rust with a light film of oil.
Notice: Water directly on a hot engine can cause
damage or worse crack the aluminum parts in the
engine. If the engine has been running, allow it to cool
for at least half an hour before washing.
Fuel Gasoline will oxidize and deteriorate during
storage. Stale gasoline will cause hard starting, and
will leave gum deposits that will clog the fuel system.
Do not keep same gasoline in engine for more than
3 months!!!
Warning: Don't start the engine with oxidize and
deteriorate gasoline in the fuel tank, it may damage the
carburetor and other fuel system components!
Preparation for long term storage
We recommend draining the fuel tank and carburetor
before long-term storage. However adding a fuel
stabilizer can extend fuel service life.
Draining the fuel tank and carburetor
We recommend draining the fuel tank first and
hereafter the carburetor.
How to:
1. Place an approved gasoline container below
the carburetor, and use a funnel to avoid
spilling fuel.
2. Remove the carburetor drain bolt, and then
pull out the fuel tube.
3. After all the fuel has drained into the container,
reattach the drain bolt and fuel tube. Ensure
that both bolt and tube are securely tightened.
Adding a fuel additive
Follow the fuel additive scale of the manufacturer.
How to:
1. Empty fuel tank for old gasoline and refill fresh.
2. Pour the fuel additive in the tank.
3. Idle run, the engine outdoors for 10 minutes.
This will blend the fuel mixture in the engine
block and carburetor.
4. Stop the engine.
Precautionary measures against moist
In order to minimize the parts to impair from moist:
1. Change the engine oil.
2. Remove the spark plugs.
3. Pour a tablespoon (5-10 cc) of clean engine oil
into the cylinder.
4. Pull the starter rope several times to distribute
the oil in the cylinder.
5. Reinstall the spark plugs.
6. Pull the starter rope slowly until resistance is
felt. This will close the valves so moisture
cannot enter the engine cylinder. Return the
starter rope gently.
