The lubrication method is a fully force-fed, full-flow fil-
tration type. The engine oil pump is a gear type
which is 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 addi-
tion, used engine oil contains potentially harmful con-
taminants 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 under-

pants, 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 per-
sonal clothing.

• Where there is a risk of eye contact, eye protec-

tion should be worn, for example, chemical gog-
gles 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 clean-
ing, 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. Pull out the engine oil level gauge slowly and

check that the oil level is in the illustrated range.

2. Check that the oil is not excessively dirty, that

there is no coolant or petrol mixed in, and that it
has sufficient viscosity.

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

temperature of the coolant reaches 80

°C to 90°C.

WARNING

Use care as oil could be hot.

2. Remove the engine oil filler cap.
3. Remove the drain plug to drain oil.

NOTE: SAE 5W-30 engine oil can be used to
improve engine startability in very cold weather
areas where the lowest atmospheric temperature
is below the range shown in the illustration. In this
case, use engine oil conforming to the following
classification:

.

•

ACEA classification: For service A3

•

API classification: For service SG or higher

6. Install the engine oil filler cap.
7. Check oil level.

CAUTION

Since sealant is applied to the thread of oil pres-
sure switch, take care not to damage the oil pres-
sure switch when removing it.
2. Use the special tool Oil pressure switch wrench

(MD998012) to remove the oil pressure switch.
NOTE: Remove the terminal of oil pressure switch
where the special tool oil pressure wrench
(MD998012) is not fitted.

3. Install the oil pressure gauge.

NOTE: Use an adapter of PT 1/8 thread.

5. After the engine has been warmed up, check that

oil pressure is within the standard value.

Standard value:

At idle: 29 kPa or more
At 3,500 r/min: 294

− 686 kPa

6. Remove the oil pressure gauge.
