•Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep
sparks and flames away from fuel.
•Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and
damage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line
Safety Procedure”. (See F2–45 Fuel Line Safety Procedures.)

Warning
•Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the
engine oil have cooled.
•A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall,
causing death or serious injury. Never work around or under a lifted vehicle if it is not securely
supported on safety stands.
•Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your
skin by washing with soap and water immediately after working with engine oil.
Caution
•In case you spill engine oil on the front pipe, wipe it off completely. If you fail to wipe the spilled
oil, it will produce fumes because of the heat.
1. Position the vehicle on level ground.
2. Remove the the oil filler cap.
3. Remove the under cover.
