CARRIAGE/BALL BUSHING
1. Use a lint-free cloth and isopropyl alcohol to clean any dust or
debris from the front guide bar, Z way bar, theta way bar, and
rear guide bar. Rotate the Z way and rear guide bar (the front
guide bar does not turn) and move the carriage spindle for
access to the entire length of these shafts.
2. The Z way bar, theta way bar, and front and rear guide bars
should be given a light coat of oil. This is best done by
applying with a lint-free cloth.
3. Place one or two drops of oil on each side of the ball bushing
and in the oil hole (as indicated).
SPROCKETS AND BAIL ARMS
1. Inspect the teeth of the drum sprockets for adhesive buildup
from the use of vinyl films.
2. Use a small stiff brush (such as a toothbrush) dipped in
isopropyl alcohol to clean the sprockets.
3. After using isopropyl alcohol to clean them, immediately dry
the sprockets and drum with a lint-free cloth.
4. Place one drop of oil in each pin of the sliding sprocket.
