How to perform maintenance task: Replace rear oiler foams and wicks
This change affects the “Replace rear oiler foam and wicks” maintenance task. This is part of “Clean carriage rails and replace oiler foams” maintenance, included in the 100L maintenance.
The new procedure, including instructions of both types of rear oilers (original and new) follows. If the machine has the new rear oiler assembly, it is recommendable to follow the new maintenance instructions described in detail; they will also be included in the new version of the User Guide at the end of September 2014.
Replace the rear oiler foam and wicks
  1. Locate the rear oiler foam in the carriage.
  2. Slide off the cover of the rear oiler foam.
  3. Remove the old foam.
  4. Loosen the two screws that attach the black oiler holder to the carriage, and pull the holder out of the carriage
  5. If the oiler also has a felt retainer fitted, remove it, and the 2 used felts. If not, skip this step.
  6. Remove the used wicks.
  7. Insert the new wicks.
    Check that the wicks are inserted correctly.
  8. If the oiler had the felt retainer fitted, insert 2 new felts, one on each side. If not, go to step 10.
  9. Insert the felt retainer.
    Check that the wicks and retainer are inserted and fitted correctly.
  10. Put the black oiler holder back into position. The holder has two pins to locate it properly.
  11. Check again that the new wicks are inserted correctly.
  12. Tighten the screws.
  13. Insert the new foam.
  14. Slide in the cover.
