CAUTION:
• Prolonged and repeated contact with engine oil will
result in the removal of natural oils from the skin,
leading to dryness, irritation and dermatitis. In
addition, used engine oil contains potentially harmful
contaminants which may cause skin cancer.
• Precautions should be taken when replacing engine
oil to minimize the risk of your skin making contact
with used engine oil. Protective clothing and gloves
that cannot be penetrated by oil should be worn. The
skin should be washed with soap and water, or
waterless hand cleaner, to remove any used engine oil
thoroughly. Do not use gasoline, thinners, or solvents.
• In order to preserve the environment, used oil and
used oil filters must be disposed of at designated
disposal sites.
1. DRAIN ENGINE OIL
(a) Remove the oil filler cap.
(b) Remove the oil drain plug, and drain the oil into a
container.
(c) Clean and install the oil drain plug with a new
gasket.
Torque: 40 N*m (408 kgf*cm, 30 ft.*lbf)
