Helpful Tips & Suggestions

STORING YOUR ENGINE

Storage Preparation
Proper storage preparation keeps your engine trouble-free and clean. The following steps will assist in keeping rust and corrosion from
impairing your engine's function and appearance, and will make the engine easier to start when using again.
Cleaning
If the engine has been running, allow it to cool for at least half an hour before cleaning. Clean all exterior surfaces and apply a light film
of spray penetrating lubricant.
• Do not allow water to enter into the exhaust ports or into the heat shield openings (intake port). Water that passes through these
areas can cause damage to the engine. Use a rag to wipe down heat shield if cleaning is required.
• Water contacting a hot engine can cause damage. If the engine has been running, allow it to cool for at least half an hour before cleaning.
• It's best to use compressed air to clean debris from engine.
Adding a Fuel Stabilizer to Extend Fuel Storage Life
• NOTICE
Fuel stabilizer is recommended for long term storage.
1. Turn the red fuel knob to the OFF position while engine is running and allow the engine to run until it stops. Turn engine OFF when
it begins surging to avoid engine damage.
2. Add fuel stabilizer, following the manufacturer's instructions.
3. Turn the red fuel knob to the ON position after adding fuel stabilizer.
4. Re-start engine.
5. Run the engine outdoors for 1 minute to be sure that treated gasoline has replaced the untreated gasoline in the carburetor.
6. Slow the engine to an idle speed.
7. Repeat step 1 above.
