Storage Location
If your trimmer will be stored with gasoline in the fuel tank and
carburetor, it is important to reduce the hazard of gasoline vapor
ignition. Select a well-ventilated dry storage area away from any
appliance that operates with a flame, such as a furnace, water heater,
or clothes dryer. Also avoid any area with a spark-producing electric
motor, or where power tools are operated.
With the engine and exhaust system cool, cover the trimmer to keep
out dust. A hot engine and exhaust system can ignite or melt some
materials. Do not use sheet plastic as a dust cover. A nonporous
cover will trap moisture around the trimmer, promoting rust and
corrosion.
Removing From Storage
Check your trimmer as described in BEFORE OPERATION (page 7).
If the fuel was drained during storage preparation, fill the tank with
fresh gasoline. If you keep a container of gasoline for refueling, be
sure that it contains only fresh gasoline. Gasoline oxidizes and
deteriorates over time, causing hard starting.
If the cylinder was coated with oil during storage preparation, the
engine may smoke briefly at startup. This is normal.
