WARNING: Highly inflammable or explosive materials

Danger of fire or explosion

→ Avoid contact with hot parts or sources of ignition.

→ Use suction to remove ignitable vapors.

→ Attach warning sign in a clearly visible position.

CAUTION: Risk of material damage when lowering engine

Damaged components must be replaced.

→ Get one or two more people to help.

NOTE: Pressure accumulator removed incorrectly

Damage to hoses and wiring

→ First relieve pressure in the clutch system.

→ Actuate the clutch pedal at least 25 times for this purpose.

Information

Remove upper hexagon-head bolts for the cross member so as to avoid damaging the reference mark sender cable and oil tank when lowering the engine/transmission unit.

Information

Get a second person to check the clearance when lowering the engine/transmission unit.
If the vehicle is placed on its wheels or moved in the workshop, the rear cross member must always be refitted in order to maintain structural strength.

Information

When opening the power-steering oil lines, make sure that Pentosin does not drop onto the rubber sleeves of the fuel injectors.
Cover this area beforehand with a cloth.
If drops of Pentosin fall onto a rubber sleeve, clean it immediately.
Replace swollen rubber sleeves.

Before opening the fuel lines, place a warning sign in a clearly visible position on the vehicle.
