Longitudinal Leadscrew
Oil Type .... Grizzly T23962 or ISO 68 Equivalent
Oil Amount ......................................... As Needed
Lubrication Frequency ................................. Daily
Before lubricating the leadscrew, clean it first
with mineral spirits. A stiff brush works well to
help clean out the threads. Make sure to move
the carriage out of the way, so you can clean the
entire length of the leadscrew.
Apply a thin coat of oil along the length of the
leadscrew. Use a stiff brush to make sure the oil
is applied evenly and down into the threads.
Note: In some environments, abrasive material
can become caught in the leadscrew lubricant and
drawn into the half nut. In this case, lubricate the
leadscrew with a quality dry lubricant.
Oil Cup
Lift the oil cup lid and fill the cup to the top. The oil
will slowly drain into the gearing over time. Refer
to Figures 106–108 and the following descrip-
tions to identify the locations of each oil device.

This lathe has seven ball oilers and one oil cup
that should be oiled on a daily basis before begin-
ning operation.
Ball Oilers
Proper lubrication of ball oilers is done with a
pump-type oil can that has a plastic or rubber-
ized cone tip. We do not recommend using metal
needle or lance tips, as they can push the ball too
far into the oiler, break the spring seat, and lodge
the ball in the oil galley.
Lubricate the ball oilers before and after machine
use, and more frequently under heavy use. When
lubricating ball oilers, first clean the outside sur-
face to remove any dust or grime. Push the rub-
ber or plastic tip of the oil can nozzle against the
ball oiler to create a hydraulic seal, then pump the
oil can once or twice. If you see sludge and con-
taminants coming out of the lubrication area, keep
pumping the oil can until the oil runs clear. When
finished, wipe away any excess oil.
