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.
