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.
