📋 Procedure

1. ⚠ Always ensure that no reducing agent contacts clothing or bodywork.If this occurs, wash out reducing agent using clear water and a lint-free cotton cloth.If the reducing agent has already crystallised, use warm water and a sponge.Reducing agent that has not been removed will crystallise and damage the surface after some time.For information on storage and disposal see Service net → Environment → Workshop disposal! Request country specific information concerning storage and disposal from importer. — Lift attachment of cap (1) slightly and turn it anticlockwise so that indentations (2) are exposed.
2. Insert special wrench from toolkit (3) into indentations and unscrew cap.
3. Close shut-off taps (A), (B) and (C).
4. Connect coupling (D) with connection to shut-off tap (A) and pressurise compressed air hose with compressed air.
5. Open shut-off tap (A).

6. Close shut-off valve (A) as soon as the pressure gauge registers a pressure of 0.8 bar.
7. Disconnect coupling (D) from connection on shut-off tap (A) and interrupt compressed air supply at compressed air hose.
8. Guide end of hose (E) into filler neck as far as base of reducing agent tank and open shut-off tap (B). [Note: The reducing agent is then drawn from the tank and into the vacuum boxVAS 6557 by the vacuum. The capacity of the vacuum boxVAS 6557 is 11 litres. The extracted volume is sufficient for removal of the reducing agent tank. If the reducing agent tank holds a greater amount and the tank is to be emptied, then repeat the process.]
9. To empty vacuum boxVAS 6557, hold connection on shut-off tap (C) over suitable container and open shut-off taps (A) and (C).
10. ⚠ Never reuse extracted reducing agent. For information on storage and disposal see Service net → Environment → Workshop disposal! Request country specific information concerning storage and disposal from importer. — Flush out vacuum boxVAS 6557 carefully using water when work sequence is complete.
