Long Term Storage
Remove the spark plug and pour about
1/4 ounce of 2-cycle mixing oil into the
cylinder through the spark plug hole.
Slowly pull the recoil starter 2 or 3 times
so oil will evenly coat the interior of the
engine. Reinstall the spark plug.
Before storing the unit, repair or replace
any worn or damaged parts.
Remove the air cleaner element from the
carburetor and clean it thoroughly with
soap and water. Let dry and reassemble
the element.
Store the unit in a clean, dust-free area.
