CAUTION:

Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi-
tion, used engine oil contains potentially harmful
contaminants which may cause skin cancer.

Exercise caution in order to minimize the length and
frequency of contact of your skin to used oil. Wear
protective clothing and gloves. Wash your skin thor-
oughly with soap and water, or use water±less hand
cleaner, to remove any used engine oil. Do not use
gasoline, thinners, or solvents.

In order to preserve the environment, used oil and
used oil filters must be disposed of only at desig-
nated disposal sites.
