[GreenKeys] Introducing Myself To The List

[Christian Gauger-Cosgrove]

Oh, one thing which you've probably already heard...

When you finally do get around to powering the machine up. The print
hammer. It has probably turned into a lovely goop that is slightly
less useful then banging your head against a cement wall. To replace
the print hammer, a suitable replacement is some plastic/rubber
tubing/hose that is fit over the arm of the print hammer. One
suggestion also made is to glue one of those round furniture pads (the
kind used to protect carpet from heavy furniture) in the place of the
rubber part of the hammer, but that repair can fail quite badly.

The reason for replacing the print hammer is that if you don't you'll
chew up the typewheel.

Cheers,
Christian
