Lubrication
For the quill, table, and column, an occasional
application of light machine oil is all that is neces-
sary. Before applying lubricant, clean off any dust
or metal chips.
Your goal is to achieve adequate lubrication. Too
much lubrication will attract dirt and dust. Various
parts of your machine could lose their freedom of
movement as a result.

quarts
Lubrication Frequency ........................... Annually
The headstock uses ISO 68 machine oil to lubri-
cate the gears.
The headstock is equipped with two different sight
glasses: an oil-level sight glass to indicate when
the proper amount of oil is in the headstock, and
an oil-flow sight glass to verify oil is circulating
properly in the headstock.
With the machine operating, it may take 1–2
minutes before the oil-flow sight glass shows the
oil. If oil is not circulating, and the headstock has
the proper amount of oil, immediately shut down
machine, and troubleshoot before proceeding
with any additional operations. The oil MUST be
properly circulating or headstock components will
become damaged from lack of lubrication.
The amount of oil in the headstock must be regu-
larly monitored before each operation to ensure
it doesn't drop below the oil-level sight glass vis-
ibility. The headstock has the proper amount of
oil when the oil-level sight glass is halfway full.
Headstock oil must be changed on an annual
basis to ensure proper lubricity of oil.
