Locate the plastic dial plate. Handle the
plastic by its edges to avoid finger smudges,
Remove the protective paper. Using a so-
lution of a few drops of household deter-
gent (Joy, Liquid Lux, etc.,) in a cup of
lukewarm water, wipe over both sides of
the
plastic plate with a sponge or soft
cloth. This will prevent static charges from
collecting on the plastic that normally
attracts dust particles, and will also clean
any smudges that may be present,
( ) Again, referring to DetaillN, mount the dial
plate so that the lettering can be read from
the front panel, the dial spacer plates, dial
back plate assembly, pulley bracket assem-
bly, and the pilot lamp bracket to the front
panel. Use #6lockwashers and 6-32 nuts on
the front panel studs. Use care when tight-
ening to prevent breaking the studs from the
front panel. Also line up the pilot lamp holes
in the dial plate, dial spacer plate, and dial
backplate.
