WARNING
Always turn off your unit before you clean
or perform any maintenance on it.
Cleaning
Use a small brush to clean off the outside of the unit. Do
not use strong detergents on plastic housing or handle.
They can be damaged by household cleaners that contain
aromatic oils such as pine and lemon, and by solvents
such as kerosene.
Storage
If the unit will be stored for an extended period of time,
use the following storage procedure.
1. Drain all fuel from the fuel tank. Make sure that the
fuel is drained into a container with the same 2-cycle
fuel mixture. Do not use fuel that has been stored for
more than 60 days. Dispose of the old fuel/oil mix in a
safe manner and use a fresh mix.
2. Start the engine and allow it to run until it stalls.
3. Allow the engine to cool. Remove the spark plug and
put approximately 1 ounce of any high quality motor
oil or 2-cycle oil into the cylinder. Pull the starter rope
slowly to distribute the oil. Reinstall the spark plug.
NOTE: Remove the spark plug and drain all of
the oil from the cylinder before attempt-
ing to start the unit after storage.
4. Thoroughly clean the unit and inspect it for any loose
or damaged parts. Repair or replace the damaged
parts and tighten any loose screws, nuts or bolts.
The unit is now ready for storage.
5. Store the unit in a dry, well-ventilated area.
