(1 ~ 3 cc) of clean engine oil into the cylinder. Pull the starter rope
several times to distribute the oil in the cylinder. Reinstall the spark
plug. Pull the starter rope slowly until resistance is felt, then return the
starter grip gently. This closes the valves so moisture cannot enter.

STORAGE PRECAUTIONS

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 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.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
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 non-porous
cover will trap moisture, promoting rust and corrosion.

REMOVAL FROM STORAGE

Check your trimmer as described in the BEFORE OPERATION
section of this manual.
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 will smoke briefly at startup. This is normal.
