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
• If engine oil is spilled on the exhaust system, wipe it off completely. If you fail to wipe the spilled
engine oil, it will produce fumes because of the heat.
• To avoid damage to the oil filter, use only specified oil filter.

Note
• Oil could be easily drained when the air is in
