Lubrication
The lathe has numerous metal-to-metal sliding
surfaces that require regular lubrication to
maintain smooth movement and ensure long-
lasting operation.
Other than the lubrication points covered in
this section, all other bearings are internally
lubricated and sealed at the factory. Simply leave
them alone unless they need to be replaced.
Before performing any lubrication task,
DISCONNECT LATHE FROM POWER!
Important: Before adding lubricant, clean away
any debris or grime from the entry points with
mineral spirits to prevent contamination of the
new lubricant.
Oil Gun
Proper lubrication of the spindle bearing and
chuck fittings is done with a pump-type oil gun
that has a plastic or rubberized cone tip. We do
not recommend using metal needle or lance tips
as they can push the ball too far into the fitting,
break the spring seat, and lodge the ball into the
oil galley. Push the rubber or plastic tip of the oil
can nozzle against the ball to create a hydraulic
seal, then add the lubricant.
Use the schedule and information in the chart
below as a daily guide for lubrication tasks.
The following schedule is based on light-to-
medium usage. Some components may need
to be lubricated more frequently depending on
usage.

Use only an ISO 32 equivalent oil to lubricate
the spindle bearings. Using a heavier lubricant
such as grease will cause the bearing to run
hot and cause excessive machine wear.
