Chapter 1 Before You Begin Tests, Maintenance, or Repairs
The grease applicator kit, catalog number SK-RM-GRAPP1, is available to
reapply grease to edge connectors on circuit boards and fiber transceivers. The
grease applicator kit contains these components.
Figure 6 - Grease Applicator Kit Contents
Follow these steps to use the grease applicator kit to apply dielectric grease to
an edge connector on a circuit board.
1. By using a lint-free alcohol wipe with 90% or higher alcohol content,
remove the contamination and grease from the connector.
2. Before you apply grease, allow the edge connector to dry thoroughly.
3. Open the grease tube and by using the pin on the side of the large
applicator, puncture the seal on the end of the tube.
4. Install the large grease applicator on the threaded tip of the tube.
5. Close the applicator cover.
6. Press the tube until the applicator-tip chamber is completely filled with
grease.
7. Open the applicator cover and verify that the chamber is full of grease.
8. If the chamber is not full of grease, repeat steps

Regarding grease coverage on edge connectors:
• Complete coverage is more important than the thickness of the grease layer.
• A thicker application of grease does not improve corrosion resistance.
The chamber is full when a grease escapes through the small holes on the
applicator cover.
