CLEANING
Use a small brush to clean the outside of the unit. Do not use strong detergents. Household cleaners
that contain aromatic oils such as pine and lemon, and solvents such as kerosene, can damage
plastic. Wipe off any moisture with a soft cloth.
STORAGE
•
Never store a fueled unit where fumes may reach an open flame or spark.
•
Allow the engine to cool before storing.
•
Lock up the unit to prevent unauthorized use or damage.
•
Store the unit in a dry, well-ventilated area.
•
Store the unit out of the reach of children.
Long-term Storage
1. Remove the fuel cap, tip the unit and drain the fuel into an approved container.
2. Start the engine and allow it to run until it stalls. This ensures that all fuel has been drained from
the carburetor.
3. Allow the engine to cool. Remove the spark plug and put 5 drops of any high quality motor oil into
the cylinder. Pull the starter rope slowly to distribute the oil. Reinstall the spark plug.
4. Thoroughly clean the unit and inspect it for any loose or damaged parts. Repair or replace
damaged parts and tighten loose screws, nuts or bolts.
Preparing the Unit for Use after Long-term Storage
1. Remove the spark plug and drain all of the oil from the cylinder.
2. Change the oil. Refer to
Changing the Oil
.
NOTE:
Do not use fuel that has been stored for more than 30 days. Dispose of old fuel and oil
according to federal, state and local regulations.
WARNING:
To avoid serious personal injury, always stop the engine and allow it to cool
before cleaning or maintaining the unit.
