SECTION 7: OFF SEASON STORAGE

If the unit will be stored for an extended time,

1.

Start the engine and allow it to run until it stalls.
This ensures that all fuel has been drained from
the carburetor.

and put 1 oz. (30 ml) of high quality motor oil 
into the cylinder. Pull the starter rope slowly to 
distribute the oil. Reinstall the spark plug.

Remove the spark plug and drain all of the oil

from the cylinder before attempting to start the unit
after storage.

loose or damaged parts. Repair or replace 
damaged parts and tighten loose screws, nuts or
bolts.

fumes may reach an open flame or spark.
