Open locking ring

1 Connect locking rings (3) for a short time conductive with the vehicle body and ground.
Grounding for components prevents electrostatic discharge (ESD). ESD can bring an escaping fuel/air mixture to explosion.

2 Unlock, detach and set aside electrical connections on fixture cover (4a) and fuel filter (4b).
3 Unlock, detach and set aside fuel lines on fuel filter (4b).
Do not kink or disconnect fuel lines to avoid damage.
Collect any escaping fuel with an absorbent rag.







4 Insert claw wrench (010) in the openings (3a) on the outside on the locking ring (3).
5 Insert long locking handle (011) into claw wrench (010) and turn locking ring (3) counterclockwise.
A high degree of force is necessary; the cap (3) clicks into place abruptly. Do not insert an extension between the locking handle (011) and the claw wrench (010).

6 Remove locking handle (011) with claw wrench (010) and locking ring (3).







Close locking ring

7 Clean contact surface of sealing ring (5) on fuel tank and locking ring (3).
Do not bring any dirt into the fuel tank in order to avoid damage and malfunctions.

8 Replace sealing ring (5) and lay in groove on fuel tank.
9 Hold by the locking ring (3) and insert locating cover (4a) or fuel filter (4b) through the opening on the fuel tank in such a way that the recess (4c) points in the direction of travel.
In order to avoid leaks, do not press sealing ring (5) out of the groove on the fuel tank in the process.
Handle left or right fuel level indicator sensor carefully to avoid deformation of the float linkage.







10 Press locating cover (4a) or fuel filter (4b) on its seat in the fuel tank and lay locking ring (3) in place.
11 Turn locking ring (3) clockwise until the catch tab (3r) lies on the left on the fastening claws (3k).







12 Carefully insert claw wrench (010) with locking handle (011) into the openings (3a) on the outside on the locking ring (3).
13 Turn locking ring (3) clockwise until the catch tab (3r) lies on the left on the recesses in the fastening claw (3k).
A high force is required. Do not insert an extension between the locking handle (011) and the claw wrench (010).







14 Turn locking ring (3) clockwise until the catch tabs (3r) between the recesses on the fastening claws (3k) engage.
A high force is required. The locking ring (3) engages abruptly.

15 Check for correct engagement of the locking ring (3).
An incorrectly engaged locking ring (3) can come loose which can lead to leaks on the fuel tank and injury to persons or damage to equipment and the environment.

16 Remove claw wrench (010) and locking handle (011).







17 Place electrical connections on fixture cover (4a) and fuel filter (4b) and check for correct engagement.
18 Place fuel lines on fuel filter (4b) and check for correct engagement.
