Storage
Gasoline can oxidize in as little as 30 days, causing gum and varnish to build up in
fuel system components.
NOTE
Ensure that the storage area is free of excess humidity and dust.
Storage Duration Preparation Required
Less than 1 Month No storage preparation required, simply store
as is.
1 Month to 1 Year Drain the old gas and completely fill the
tank with fresh gas before storage. Add fuel
stabilizer according to the manufacturer’s
directions. Adding a quality fuel stabilizer can
keep gas fresh for up to a year.
1 Year or More Drain off the gasoline from the fuel tank, and
store in a suitable container. This will help prevent
deposits from forming in the fuel system.
Turn the fuel switch to OPEN and loosen the
carburetor drain bolt. Take off the spark plug cap
and revolve the engine 3 or 4 times, by pulling the
recoil handle, to fully discharge the gasoline from
the fuel lines.
Turn the fuel switch to CLOSED and tighten the
drain bolt of the carburetor.
Change oil while engine is still warm from
operation.
Remove the spark plug, and pour a tablespoon
of clean engine oil (10~20ml) into the cylinder.
Revolve the engine several times by pulling on
the recoil start to distribute the oil. Reinstall the
spark plug. Pull the starter grip slowly until you feel
resistance. At this point, the piston is coming up
on its compression stroke and both the intake and
exhaust valves are closed. This position helps to
protect the engine from internal corrosion.
