driven by the crankshaft via the timing belt.

ENGINE OILS
Health Warning

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
addition, used engine oil contains potentially harmful
contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must be provided.

Recommended Precautions

The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example by
using enclosed systems for handling used engine oil
and by degreasing components, where practicable,
before handling them. Other precautions:

• Avoid prolonged and repeated contact with oils,

particularly used engine oils.

• Wear protective clothing, including impervious

gloves where practicable.

• Avoid contaminating clothes, particularly

underpants, with oil.

• Do not put oily rags in pockets, the use of overalls

without pockets will avoid this.

• Do not wear heavily soiled clothing and

oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.

• Where there is a risk of eye contact, eye

protection should be worn, for example, chemical
goggles or face shields; in addition an eye wash
facility should be provided.

• Obtain First Aid treatment immediately for open

cuts and wounds.

• Wash regularly with soap and water to ensure all

oil is removed, especially before meals (skin
cleansers and nail brushes will help). After
cleaning, the application of preparations
containing lanolin to replace the natural skin oils
is advised.

• Do not use petrol, kerosine, diesel fuel, gas oil,

thinners or solvents for cleaning skin.

• Use barrier creams, applying them before each

work period, to help the removal of oil from the
skin after work.

• If skin disorders develop, obtain medical advice

without delay.

1. Start the engine and allow it to warm up until the

temperature of the coolant reaches 80

°C to 90

°C.

2. Remove the engine oil filler cap.

CAUTION

Use care as engine oil could be hot.
3. Remove the engine oil pan drain plug to drain

engine oil.

4. Install a new engine oil pan drain plug gasket so

that it faces in the direction shown in the
illustration, and then tighten the engine oil pan
drain plug to the specified torque.

Tightening torque: 39

± 5 N⋅m

NOTE: Install the engine oil pan drain plug gasket
so it faces in the direction shown in the illustration.
