Preparing the Engine
For engines stored over 30 days:
To prevent gum from forming in fuel system or on carburetor parts, run
engine until it stops from lack of fuel or add a gasoline additive to the gas
in the tank. If you use a gas additive, run the engine for several minutes to
circulate the additive through the carburetor—after which the engine and
fuel can be stored up to six months.
While engine is still warm, change the oil. See Change Engine Oil in SERVICE
AND MAINTENANCE section.
Remove spark plug and pour approximately 1 oz. (30 ml) of clean engine oil
into the cylinder. Pull the recoil starter several times to distribute the oil, and
reinstall the spark plug.
Clean engine of surface debris.
Never store chipper shredder with fuel in tank indoors or in poorly ventilated
areas where fuel fumes may reach an open flame, spark, or pilot light as on a
furnace, water heater, clothes dryer, or gas appliance.
Preparing the Chipper/Shredder
When storing the chipper shredder in an unventilated or metal storage
shed, care should be taken to rustproof the non-painted surfaces. Using a
light oil or silicone, coat the equipment, especially any springs, bearings, and
Remove all dirt from exterior of engine and equipment.
Follow lubrication recommendations.
Store equipment in a clean, dry area. Do not store next to corrosive materials,
such as fertilizer. Do not store in an area where equipment is present that
may use a pilot light or has a component that can create a spark.
