WARNING
Gaseous vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Storing Fuel Or Equipment With Fuel In Tank
• Store away from furnaces, stoves, water heaters or other appliances that have
pilot lights or other ignition sources because they can ignite fuel vapors.
Engine Oil
While the engine is still warm, change the engine oil. See the Change Engine Oil
section.
NOTICE
Store the engine level (normal operating position). If the engine is tipped in
any other direction, it may be difficult to start due to oil contaminating the air filter and/
or the spark plug.
Troubleshooting
For assistance, contact your local dealer or go to VanguardEngines.com or call
