Lubrication
The four drum bearings in the bearing blocks need to be lubricated every 20 hours of operation. However, all other bearings used on this machine are shielded and permanently lubricated. Simply leave them alone until they need to be replaced. DO NOT lubricate them, as this will only attract dust and cause possible premature bearing failure.
DO NOT apply grease on any exposed areas on the sander like the feed conveyor chain, sprockets, and the table lead screws. If you do, sanding dust and abrasives will collect on these parts and create a gummy mixture that can hamper proper movement of components and increase wear. Use a light machine oil and a dry graphite lubricant.

MAINTENANCE
To lubricate the sander, do these steps:
1.Unplug the double drum sander.
2.Clean the sander as outlined in General Cleaning procedures on Page 34.
3.Open the dust hood to gain access to the four
