1. Use a lint-free cloth and alcohol to clean any dust or debris from the
front way, drive shaft, cam shaft and rear way. Rotate the cam shaft
and rear way (the front way does not turn) and move the carriage
spindle for access to the entire length of these shafts.
2. The rear way and front way should be given a light coat of oil. This
is best done by applying with a lint-free cloth.
