CLP takes on crunchy snow and loses (almost)

[Newton Hunt]

Use Teflon spray, with WD-40 button and tube, depress damper pedal,
spray damper lift rod and damper felt from under neat.  No action
removal.

Also use the same setup to spray damper spring seats if felt.

Also check rod and reach interface, lever and reach interface, lever
spring, pedal rod and pedal and pedal rod and lever interfaces.

Check pivot brackets and if bottom board screws are loose enough to
cause noise.

Check casters for noise.

Check toe rail, legs, toes, keybed and sides.
