• Inspect the door mechanism for wear. Contact ETS-Lindgren if any parts require replacement.
• For damage to the door contact fingers, see
Door Finger Replacement section of this guide.
• To seal properly, the door must close and seat evenly at all points. The three roller cam ramps and
rollers hold the door tightly in place. If adjustment is required, add a thin piece of shim stock behind
the ramp and replace it. This will increase the pressure on the roller and cause the door to sit tighter
in the jamb at that point.
If additional contact pressure is required, gently pull the phosphor bronze contact fingers.
