5. Clean the power carrier and inspect all parts to make sure they are securely
tightened. Lubricate the points noted on page 49.
NOTE: If the carrier will be stored for more than three months, remove the
spark plug, pour a tablespoon (5-10~~) of clean engine oil into the cylinder.
Pull the starter rope slowly two or three times to distribute the oil. Reinstall the
spark plug.

7. With the engine and exhaust system cool, cover the power carrier 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 power carrier, promoting rust and corrosion.
