[CAUT] Funny Noises

[William Schneider]

Ken,

Here's an odd occasional source of clicks: Sometimes if the jack rest
regulating button screw threads are a bit loose in the jack, on a hard blow
the inertia of the jack will cause the screw to move a thousanth or two when
the jack stops its escapement stroke, causing a surprisingly loud click.
Removing the screw and inserting a piece of dental floss in the hole with
the screw will tighten the threads just enough to stop the noise.
